    Figures recently issued by Co-operativesUK show that co-operative business grew by 1.5% in 2011, twice the rate of the UK economy as a whole. This is the fourth consecutive year that the co-operative sector has outperformed the rest of UK business. The figures also show that it is not only in growth that co-operative businesses do better, they are also much more reliant - 98% are still in operation after three years compared to 65% of all businesses. Also 88% try to minimize the environmental impact of their activities compared to 44% of all businesses who state they do not take any action in this regard at all. Membership of trading co-operatives from 2010 to 2011 grew by 5.5% to 13.5 million people - the increase from 2008 to 2011 is 19.7%. Currently the number of co-operatives in the UK is around 5,900 - a growth of 23% from 2008. The largest growth by sector was in the renewable energy sector, and there are now 242 co-operative schools across the country.

  • I posit an optimistic view of the potential for Society from the emergence of a new and “Open” form of Capitalism.
  • Open Capital
  • the concept of “Open” Capital is “so simple…. it repels the mind".
  • ...162 more annotations...
  • Open Capital is defined as “a proportional share in an enterprise for an indeterminate time”
  • ‘Enterprise’ is defined as ‘any entity within which two or more individuals create, accumulate or exchange Value”.
  • Value is to Economics as Energy and Matter are to Physics.
  • The Metaphysics Of Value
  • division between “subject” and “object”.
  • primary reality is “Quality”
  • formless and indefinable
  • not a “thing”
  • a non-intellectual awareness or “pre-intellectual reality”
  • but an event at which the subject becomes aware of the object and before he distinguishes it
  • Quality is the basis of both subject and object
  • distinguish between “Static” and “Dynamic” Quality
  • treating Value as a form of “Quality” as envisioned by Pirsig.
  • Riegel
  • defined “Value” as “ the Relativity of Desire” again implying indeterminacy.
  • Pirsig’s approach Capital may be viewed as “Static” Value and Money as “Dynamic” Value. “Transactions” are the “events” at which individuals (Subjects) interact with each other or with Capital (both as Objects) to create forms of Value and at which “Value judgments” are made based upon a “Value Unit”.
  • The result of these Value Events /Transactions is to create subject/object pairings in the form of data ie Who “owns” or has rights of use in What,
  • at what Price
  • accounting data
  • Neo-Classical” Economics confuses indeterminate Value with a market– determined Price –
  • Data may be static
  • This Data identifies the subject with objects such as tangible ‘Material Value’
  • Data may itself constitute ‘Intellectual Value’
  • It, too, may then be defined in a subject/object pairing through the concept of “intellectual property”.
  • Other forms of Value are however not definable by data:
  • “sentimental” Value
  • Emotional Value’
  • 'Spiritual Value’
  • We may therefore look at the “transaction” or “value event” in a new light.
  • The creation and circulation of Value essentially comprises the concept we know of as “Money”.
  • Money / Dynamic Value
  • “The purpose of money is to facilitate barter by splitting the transaction into two parts, the acceptor of money reserving the power to requisition value from any trader at any time
  • money
  • value unit dissociated from any object
  • monetary unit
  • the basis relative to which other values may be expressed
  • The monetary process is a dynamic one involving the creation and recording of obligations as between individuals and the later fulfilment of these obligations
  • The monetary “Value Event”/ Transaction involves the creation of “Credit”
  • obligation to provide something of equivalent Value at a future point in time.
  • These obligations may be recorded on transferable documents
  • database of “Credit”/obligations is not Money, but temporary “Capital”
  • “Working Capital”
  • Static Value – which only becomes “Money”/ Dynamic Value when exchanged in the transitory Monetary process.
  • what we think of as Money is in fact not tangible “cash” but rather
  • the flow of data between databases of obligations maintained by Credit Institutions
  • or dynamic
  • Banks literally “loan” Money into existence
  • In exchange for an obligation by an Individual to provide to the Bank something of Value
  • Bank’s obligation is merely to provide another obligation at some future time
  • These Bank-issued obligations are therefore
  • claim upon a claim upon Value
  • The true source of Credit is the Individual, not the intermediary Bank
  • this Money they create from nothing despite the fact that it is literally Value-less
  • Thus there is no true sharing of Risk and Reward involved in Lending
  • issue in relation to Credit/Debt and this relates to the nature of Lending itself.
  • the practice of Lending involves an incomplete exchange in terms of risk and reward: a Lender, as opposed to an Investor, has no interest in the outcome of the Loan, and requires the repayment of Principal no matter the ability of the Borrower to repay.
  • Ethical problem
    • Tiberius Brastaviceanu
      Tiberius Brastaviceanu on 02 Jun 11
       
      "The Lender has no interest in the outcome of the loan", i.e doesn't care what happens in the end. The Lender ins not interested in the economical outcome of the Lender-Loner relation. So in fact there is no real risk sharing. the only risk for the Lender is when the Loner doesn't pay back, which is not really a risk... In fact it is a risk for the small bank, who has to buy money from the central bank, but not for the central bank. 
  • Money is not
  • an “Object” circulating but rather a dynamic process of Value creation and exchange by reference to a “Value Unit”.
  • Capital/ Static Value
  • Capital represents the static accumulation of Value
  • Some forms of Capital are “productive”
  • An ethical question
  • in relation to Productive Capital relates to the extent of “property rights” which may be held over it thereby allowing individuals to assert “absolute” permanent and exclusive ownership - in particular in relation to Land
  • our current financial system is based not upon Value but rather a claim upon Value
  • Financial Capital consists of two types:
  • “Debt”
  • “Equity”
  • Interest
  • obligations of finite/temporary duration but with no participation in the assets or revenues
  • absolute and permanent ownership/participation (without obligation) in assets and revenues
  • discontinuity between Debt and Equity
  • at the heart of our current problems as a Society
  • The Enterprise
  • ‘Charitable’ Enterprise
  • ‘Social’ Enterprise
  • Value
  • exchanged in agreed proportions;
  • Value is exchanged for the Spiritual and Emotional Value
  • ‘Commercial’ Enterprise
  • ‘closed’
  • Value are exchanged between a limited number of individuals
  • Early enterprises were partnerships and unincorporated associations
  • need for institutions which outlived the lives of the Members led to the development of the Corporate body with a legal existence independent of its Members
  • The key development in the history of Capitalism was the creation of the ‘Joint Stock’ Corporate with liability limited by shares of a ‘Nominal’ or ‘Par’ value
  • over the next 150 years the Limited Liability Corporate evolved into the Public Limited Liability Corporate
  • Such “Closed” Shares of “fixed” value constitute an absolute and permanent claim over the assets and revenues of the Enterprise to the exclusion of all other “stakeholders” such as Suppliers, Customers, Staff, and Debt Financiers.
  • The latter are essentially ‘costs’ external to the
  • owners of the Enterprise
  • maximise ‘Shareholder Value’
  • There is a discontinuity/ fault-line within the ‘Closed’ Corporate
  • It has the characteristics of what biologists call a ‘semi-permeable membrane’ in the way that it allows Economic Value to be extracted from other stakeholders but not to pass the other way.
    • Tiberius Brastaviceanu
      Tiberius Brastaviceanu on 02 Jun 11
       
      It is a way to extract value from productive systems. It is a system of exploitation. 
  • Capital most certainly is and always has been - through the discontinuity (see diagram) between:‘Fixed’ Capital in the form of shares ie Equity; and ‘Working’ Capital in the form of debt finance, credit from suppliers, pre-payments by customers and obligations to staff and management.
  • irreconcilable conflict between Equity and Debt
  • xchange of Economic Value in a Closed Corporate is made difficult and true sharing of Risk and Reward is simply not possible
  • No Enterprise Model has been capable of resolving this dilemma. Until now.
  • Corporate Partnerships with unlimited liability
  • mandatory for partnerships with more than 20 partners to be incorporated
  • in the USA
  • it is the normal structure for professional partnerships
  • Limited Liability Partnerships
  • In the late 1990's
  • litigation
  • The UK LLP is supremely simple and remarkably flexible.
  • All that is needed is a simple ‘Member Agreement’ – a legal protocol which sets out the Aims, Objectives. Principles of Governance, Revenue Sharing, Dispute Resolution, Transparency and any other matters that Members agree should be included. Amazingly enough, this Agreement need not even be in writing, since in the absence of a written agreement Partnership Law is applied by way of default.
  • The ease of use and total flexibility enables the UK LLP to be utilised in a way never intended – as an ‘Open’ Corporate partnership.
  • ‘Open’ Corporate Partnership
  • concepts which characterise the ‘Open’ Corporate Partnership
  • it is now possible for any stakeholder to become a Member of a UK LLP simply through signing a suitably drafted Member Agreement
  • ‘Open’
  • supplier
  • employee
  • may instead become true Partners in the Enterprise with their interests aligned with other stakeholders.

      Can SENSORICA be a UK LLP?
  • no profit or loss in an Open Corporate Partnership, merely Value creation and exchange between members in conformance with the Member Agreement.
  • Proportional shares
  • in an Enterprise constitute an infinitely divisible, flexible and scaleable form of Capital capable of distributing or accumulating Value organically as the Enterprise itself grows in Value or chooses to distribute it.
  • Emergence of “Open” Capital
  • example of how ‘Temporary Equity’ may operate in practice
  • The Open Capital Partnership (“OCP”)
  • Within the OCP Capital and Revenue are continuous: to the extent that an Investee pays Rental in advance of the due date he becomes an Investor.
  • Open Capital – a new Asset Class
  • create a new asset class of proportional “shares”/partnership interests
  • in Capital holding OCP’s
  • Property Investment Partnerships (“PIP’s”)
  • Open Corporate Partnerships as a Co-operative Enterprise model
  • A Co-operative is not an enterprise structure: it is a set of Principles that may be applied to different types of enterprise structure.
  • Within a Partnership there is no “Profit” and no “Loss”.
  • Partnerships
  • mutual pursuit of the creation and exchange of Value
  • Partners do not compete with each othe
  • the crippling factors in practical terms have been, inter alia: the liability to which Member partners are exposed from the actions of their co-partners on their behalf; limited ability to raise capital.
  • they favour the interests of other stakeholders, are relatively restricted in accessing investment; are arguably deficient in incentivising innovation.
  • The ‘new’ LLP was expressly created to solve the former problem by limiting the liability of Member partners to those assets which they choose to place within its protective ‘semi-permeable membrane’
  • However, the ability to configure the LLP as an “Open” Corporate permits a new and superior form of Enterprise.
  • it is possible to re-organise any existing enterprise as either a partnership or as a partnership of partnerships.
  • the revenues
  • would be divided among Members in accordance with the LLP Agreement. This means that all Members share a common interest in collaborating/co-operating to maximise the Value generated by the LLP collectively as opposed to competing with other stakeholders to maximise their individual share at the other stakeholders’ expense.
  • facilitate the creation of LLP’s as “Co-operatives of Co-operatives”.
  • he ‘Commercial’ Enterprise LLP – where the object is for a closed group of individuals to maximise the value generated in their partnership. There are already over 7,000 of these.
    • Tiberius Brastaviceanu
      Tiberius Brastaviceanu on 02 Jun 11
       
      Can SENSORICA be one of these?
  • the Profit generated in a competitive economy based upon shareholder value and unsustainable growth results from a transfer of risks outwards, and the transfer of reward inwards, leading to a one way transfer of Economic Value.
  • This,
  • will very often impoverish one or more constituency of stakeholders
  • A partnership, however, involves an exchange of value through the sharing of risk and reward.
  • Whether its assets are protected within a corporate entity with limited liability or not, it will always operate co-operatively – for mutual profit.
  • Open Capital, Economics and Politics
  • continuity between Capital as Static Value and Money as Dynamic Value which has never before been possible due to the dichotomy between the absolute/infinite and the absolute/finite durations of the competing claims over assets – “Equity” and “Debt”
  • Open Capital Partnership gives rise to a new form of Financial Capital of indeterminate duration. It enables the Capitalisation of assets and the monetisation of revenue streams in an entirely new way.
  • It is possible to envisage a Society within which individuals are members of a portfolio of Enterprises constituted as partnerships, whether limited in liability or otherwise.
  • Some will be charitable
  • Others will be ‘social’
  • ‘Commercial’ enterprises of all kinds aimed at co-operatively working together to maximise value for the Members.
  • the process has already begun
  • Capitalism
  • superior
  • to all other models, such as Socialism.
  • It can only be replaced by another ‘emergent’ phenomenon, which is adopted ‘virally’ because any Enterprise which does not utilise it will be at a disadvantage to an Enterprise which does.
  • The ‘Open’ Corporate Partnership is: capable of linking any individuals anywhere in respect of collective ownership of assets anywhere; extremely cheap and simple to operate; and because one LLP may be a Member of another it is organically flexible and ‘scaleable’. The phenomenon of “Open Capital” – which is already visible in the form of significant commercial transactions - enables an extremely simple and continuous relationship between those who wish to participate indefinitely in an Enterprise and those who wish to participate for a defined period of time.
  • Moreover, the infinitely divisible proportionate “shares” which constitute ‘Open’ Capital allow stakeholder interests to grow flexibly and organically with the growth in Value of the Enterprise. In legal terms, the LLP agreement is essentially consensual and ‘pre-distributive’: it is demonstrably superior to prescriptive complex contractual relationships negotiated adversarially and subject to subsequent re-distributive legal action. Above all, the ‘Open’ Corporate Partnership is a Co-operative phenomenon which is capable, the author believes, of unleashing the “Co-operative Advantage” based upon the absence of a requirement to pay returns to “rentier” Capitalists.

      Very similar to SENSORICA, an environment of entrepreneurs. The argument against this is that not everyone is a risk taker or has initiative. The answer to it is that not every role in the organization requires that.

  • The system is not made up of artifacts but rather an elegantly designed void. He says “I prefer to use the analogy of rescuing an endangered species from extinction, rather than engaging in an invasive breeding program the focus should be on the habitat that supports the species. Careful crafting of the habitat by identifying the influential factors; removing those that are detrimental, together with reinforcing those that are encouraging, the species will naturally re-establish itself. Crafting the habitat is what I mean by designing the void.”

  • It is essential that autonomy is combined with responsibility.
  • staff typically manage the whole work process from making sales, manufacture, accounts, to dispatch
  • they are also responsible for managing their own capitalization; a form of virtual ownership develops. Everything they need for their work, from office furniture to high-end machinery will appear on their individual balance sheet; or it will need to be bought in from somewhere else in the company on a pay-as-you go or lease basis. All aspects of the capital deployed in their activities must be accounted for and are therefore treated with the respect one accords one’s own property.

  • The result is not simply a disparate set of individuals doing their own thing under the same roof. Together they benefit from an economy of scale as well as their combined resources to tackle large projects; they are an interconnected whole. They have in common a brand, which they jointly represent, and also a business management system (the Say-Do-Prove system) - consisting not only of system-wide boundaries but also proprietary business management software which helps each take care of the back-end accounting and administrative processing. The effect is a balance between freedom and constraint, individualism and social process.
  • embodiment of meaning
  • But culture is a much more personal phenomenon
  • Culture is like climate- it does not exist in and of itself- it cannot exist in a vacuum, it must exist within a medium.
  • underlying culture
  • Incompatibility between the presenting culture and the underlying one provide a great source of tension
  • The truth of course is that when tension builds to a critical level it takes just a small perturbation to burst the bubble and the hidden culture reveals itself powered by the considerable pent-up energy.

  • Consider again the idea that for the health of an endangered species; the conditions in their habitat must be just right. In business, the work environment can be considered analogous to this idea of habitat.
  • A healthy environment is one that provides a blank canvas; it should be invisible in that it allows culture to be expressed without taint
  • The over-arching, high-level obligations are applied to the organization via contractual and legal terms.
  • But it is these obligations that the traditional corporate model separates out into functions and then parcels off to distinct groups. The effect is that a clear sight of these ‘higher’ obligations by the people at the front-end is obstructed. The overall sense of responsibility is not transmitted but gets lost in the distortions, discontinuities and contradictions inherent in the corporate systems of hierarchy and functionalization.
  • employees are individually rewarded for their contribution to each product. They are not “compensated” for the hours spent at work. If an employee wants to calculate their hourly rate, then they are free to do so however, they are only rewarded for the outcome not the duration of their endeavors.
  • Another simplification is the application of virtual accounts (Profit and Loss (P&L) account and Balance Sheet) on each person within the business.
  • The company systems simply provide a mechanism for cheaply measuring the success of each individual’s choices. For quality the measure is customer returns, for delivery it is an on-time-and-in-full metric and profit is expressed in terms of both pounds sterling and ROI (return on investment).

  • The innumerable direct links back to an external reality -like the fragile ties that bound giant Gulliver, seem much more effective at aligning the presenting culture and the underlying embodied culture, and in doing so work to remove the existing tension.
  • With a culture that responds directly to reality, the rules in the environment can be “bounding” rather than “binding”- limiting rather than instructive; this way individual behavior need not be directed at all. The goal is to free the individual to express himself fully through his work, bounded only by the limits of the law. With clever feedback (self-referencing feedback loops) integrated into the design, the individuals can themselves grow to collectively take charge of the system boundaries, culture and even the environment itself, always minded of the inherent risks they are balancing, leaving the law of the land as the sole artificial boundary.
  • the conventional company, which, instead of rewarding enterprise, trains compliance by suppressing individual initiative under layer upon layer of translation tools.

  • a new member of staff at Matt Black Systems
  • recruited by another staff member (sponsor) and they will help you learn the basics of the business management system- they will help you get to know the ropes.
  • jobs are passed to new staff members, a royalty payment can be established on the work passed over.
  • Along with that job you will be given a cash float (risk capital), P&L Account, a Balance Sheet and computer software to help plan and record your activities. Your operation is monitored by your sponsor to see if you increase the margin or volume, and so establish a sustainable operation. Training and mentoring is provided to support the steep learning curve - but without removing the responsibility of producing a return on the sponsor’s risk capital.
  • You will, in the meantime be looking to establish some of your own work for which you will not have to pay a commission or royalty to your sponsor and this will provide you with more profitable operations such that eventually you might pass back to the sponsor the original operation, as it has become your lowest margin activity. It will then find its way to a new employee (along with the associated Balance Sheet risk capital) where the process is repeated by the sponsor.[4]
  • Remuneration for staff is calibrated in a way that reflects the balance of different forces around ‘pay’
  • there is an obligation upon the company to pay a minimum wage even if the profitability of the operation does not support this
  • there are therefore two aspects of the basic pay structure: one is “absolute” and reflects the entrepreneurial skill level of the employee according to a sophisticated grading scale
  • A further 20% of the original profit will be paid into his risk capital account, which will be his responsibility to deploy in any way he sees fit as part of his Balance Sheet. Of the three remaining 20% slices of the original profit, one is paid out as corporation tax, another as a dividend to the shareholders and the last retained as collective risk capital on the company’s balance sheet- a war chest so to speak.
  • Julian Wilson and Andrew Holm sell products / services to their staff (such as office space and software) they have an identical customer/supplier relationship with the other employees.
  • Naturally there are some people that can’t generate a profit. The sponsor’s risk capital will eventually be consumed through pay. After a process of rescue and recovery- where their shortcomings are identified and they are given the opportunity to put them right, they either improve or leave, albeit with a sizeable increase in their skills.
  • there is a gradual process of accustomisation; the void of the new employee is surrounded by others dealing with their particular activities, offering both role models and operations they may wish to relinquish. One step at a time the new employee acquires the skills to become completely self-managing, to increase their margins, to make investments, to find new business, to become a creator of their own success. Ultimately, they learn to be an entrepreneur.
  • responsible autonomy as an alternative vision to traditional hierarchy

  • scientific management employs rationalism and determinism in pursuit of efficiency, but leaves no place for self-determination for most people within the system.
  • Command and Control
  • today, a really “modern” view of an organization is more likely to be depicted in terms that are akin to an organism.
  • When it comes to getting work done, the simple question is: are people the problem or the solution?
  • the Taylorist approach may be more real in theory than in practice: its instrumentalist view of the workforce is cursed by unintended consequences.

  • The natural, human reaction to this is unionization, defiance and even outright rebellion; to counter this, management grows larger and more rigid in pursuit of compliance, organizations become top heavy with staff who do not contribute directly to the process of value creation but wield power over those who do.

  • The removal of hierarchy and specialization is key to a massive improvement in both profitability and productivity. In summary: there are no managers in the company, or foremen, or sales staff, or finance departments; the company is not functionally compartmentalized and there is no hierarchy of command. In fact every member of staff operates as a virtual micro-business with their own Profit & Loss account and Balance Sheet, they manage their own work and see processes through from end to end

  • The human qualities which are of greatest potential value to the business are: curiosity, imagination, creativity, cooperation, self-discipline and realization (bringing ideas to reality)
  • These qualities are the very ones most likely to be withheld by an individual when the environment is ‘wrong’.
  • Any elements in the business environment that undermine the autonomy and purpose of the individual will see the above qualities withheld
  • High on the list of undermining elements come power-hierarchy and over-specialization
  • the responsibility of the individual is formalized, specified and restricted. An improved system is not one where responsibility is distributed perfectly but rather one where there is simply no opportunity for responsibility to be lost (via the divisions between the chunks). Systems must be reorganized so responsibility -the most essential of qualities -is protected and wholly preserved.
  • Matt Black Systems believe this can only be done by containing the whole responsibility within an individual, holding them both responsible and giving them ‘response-ability’
  • The experience of Matt Black Systems demonstrates that radical change is possible
  • productivity is up 300%, the profit margin is up 10%[3], customer perception has shifted from poor to outstanding, product returns are at less than 1%, “on time and in full” delivery is greater than 96%, pay has increased 100%.
  • staff develop broader and deeper skills and feel greater job security; they get direct feedback from their customers which all go to fuel self-confidence and self-esteem.
  • the staff manage themselves
  • “only variety can absorb variety”.
  • What is particular about their story is that behind it is a very consciously crafted design that surrounds the individualism of each person with hard boundaries of the customer, the law and the business. It is these boundaries rather than the instructive persona of ‘the boss’ that gives rise to the discipline in which individuals can develop. Autonomy is not the same as freedom, at least not in the loose sense of ‘do as you please’. An autonomous person is a person who has become self-governing, who has developed a capacity for self-regulation, quite a different notion from the absence of boundaries. Indeed, it is with establishing the right boundaries that the business philosophy is most concerned. The company provides the crucible in which the individual can develop self-expression but the container itself is bounded. Wilson calls this “designing the void”. This crucible is carefully constructed from an all-encompassing, interconnecting set of boundaries that provide an ultimate limit to behaviours (where they would fall foul of the law or take risks with catastrophic potential). It is an illusion to think, as a director of a company, that you are not engaged in a process of social conditioning; the basis of the culture is both your responsibility and the result of your influence. The trick is to know what needs to be defined and what needs to be left open. The traditional authoritarian, controlling characters that often dominate business are the antithesis of this in their drive to fill this void with process, persona and instruction. Alternatively, creating an environment that fosters enterprise, individuals discover how to be enterprising.

  • s. Euclidean space
  • metric space
  • topological space
  • Physical space is the extension surrounding a point
  • My presentation of a general theory of living systems will employ two sorts of spaces in which they may exist, physical or geographical space and conceptual or abstracted spaces
  • Physical or geographical space
  • Euclidean space
  • distance
  • moving
  • maximum speed
  • objects moving in such space cannot pass through one another
  • friction
  • The characteristics and constraints of physical space affect the action of all concrete systems, living and nonliving.
  • information can flow worldwide almost instantly
  • Physical space is a common space
  • Most people learn that physical space exists, which is not true of many spaces
  • They can give the location of objects in it
  • Conceptual or abstracted spaces
  • Peck order
  • Social class space
  • Social distance
  • Political distance
  • life space
  • semantic space
  • Sociometric space
  • A space of time costs of various modes of transportation
  • space of frequency of trade relations among nations.
  • A space of frequency of intermarriage among ethnic groups.
  • These conceptual and abstracted spaces do not have the same characteristics and are not subject to the same constraints as physical space
  • Social and some biological scientists find conceptual or abstracted spaces useful because they recognize that physical space is not a major determinant of certain processes in the living systems they study
  • interpersonal relations
  • one cannot measure comparable processes at different levels of systems, to confirm or disconfirm cross-level hypotheses, unless one can measure different levels of systems or dimensions in the same spaces or in different spaces with known transformations among them
  • It must be possible, moreover, to make such measurements precisely enough to demonstrate whether or not there is a formal identity across levels
  • fundamental "fourth dimension" of the physical space-time continuum

  • Matter and energy
  • Matter is anything which has mass (m) and occupies physical space.
  • Energy (E) is defined in physics as the ability to do work.
  • kinetic energy
  • potential energy
  • rest mass energy
  • Mass and energy are equivalent
  • Living systems need specific types of matter-energy in adequate amounts
  • Energy for the processes of living systems is derived from the breakdown of molecules
  • Any change of state of matter-energy or its movement over space, from one point to another, I shall call action.
  • It is one form of process.
  • information (H)
  • Transmission of Information
  • Meaning is the significance of information to a system which processes it: it constitutes a change in that system's processes elicited by the information, often resulting from associations made to it on previous experience with it
  • Information is a simpler concept: the degrees of freedom that exist in a given situation to choose among signals, symbols, messages, or patterns to be transmitted.
  • The set of all these possible categories (the alphabet) is called the ensemble or repertoire
  • .) The unit is the binary digit, or bit of information
  • . The amount of information is measured as the logarithm to the base 2 of the number of alternate patterns
  • Signals convey information to the receiving system only if they do not duplicate information already in the receiver. As Gabor says:
  • [The information of a message can] be defined as the 'minimum number of binary decisions which enable the receiver to construct the message, on the basis of the data already available to him.'
  • meaning cannot be precisely measured
  • Information is the negative of uncertainty.
  • information is the amount of formal patterning or complexity in any system.
  • The term marker was used by von Neumann to refer to those observable bundles, units, or changes of matter-energy whose patterning bears or conveys the informational symbols from the ensemble or repertoire.
  • If a marker can assume n different states of which only one is present at any given time, it can represent at most log2n bits of information. The marker may be static, as in a book or in a computer's memory
  • Communication of almost every sort requires that the marker move in space, from the transmitting system to the receiving system, and this movement follows the same physical laws as the movement of any other sort of matter-energy. The advance of communication technology over the years has been in the direction of decreasing the matter-energy costs of storing and transmitting the markers which bear information.
  • There are, therefore, important practical matter-energy constraints upon the information processing of all living systems exerted by the nature of the matter-energy which composes their markers.
  • organization is based upon the interrelations among parts.
  • If two parts are interrelated either quantitatively or qualitatively, knowledge of the state of one must yield some information about the state of the other. Information measures can demonstrate when such relationships exist
  • The disorder, disorganization, lack of patterning, or randomness of organization of a system is known as its entropy (S)
  • the statistical measure for the negative of entropy is the same as that for information
  • entropy becomes a measure of the probability
  • Increase of entropy was thus interpreted as the passage of a system from less probable to more probable states.
  • according to the second law, a system tends to increase in entropy over time, it must tend to decrease in negentropy or information.
  • therefore no principle of the conservation of information
  • The total information can be decreased in any system without increasing it elsewhere
  • but it cannot be increased without decreasing it elsewhere
  • . Making one or more copies of a given informational pattern does not increase information overall, though it may increase the information in the system which receives the copied information.
  • transforms information into negative entropy
  • smallest possible amount of energy used in observing one bit of information
  • calculations of the amount of information accumulated by living systems throughout growth.
  • the concept of Prigogine that in an open system (that is one in which both matter and energy can be exchanged with the environment) the rate of entropy production within the system, which is always positive, is minimized when the system is in a steady state.
  • in systems with internal feedbacks, internal entropy production is not always minimized when the system is in a stationary state. In other words, feedback couplings between the system parameters may cause marked changes in the rate of development of entropy. Thus it may be concluded that the "information flow" which is essential for this feedback markedly alters energy utilization and the rate of development of entropy, at least in some such special cases which involve feedback control. While the explanation of this is not clear, it suggests an important relationship between information and entropy
  • amount of energy actually required to transmit the information in the channel is a minute part of the total energy in the system, the "housekeeping energy" being by far the largest part of it
  • In recent years systems theorists have been fascinated by the new ways to study and measure information flows, but matter-energy flows are equally important. Systems theory is more than information theory, since it must also deal with energetics - such matters as
  • the flow of raw materials through societies
  • Only a minute fraction of the energy used by most living systems is employed for information processing
  • I have noted above that the movement of matter-energy over space, action, is one form of process. Another form of process is information processing or communication, which is the change of information from one state to another or its movement from one point to another over space
  • Communications, while being processed, are often shifted from one matter-energy state to another, from one sort of marker to another
  • transformations go on in living systems
  • One basic reason why communication is of fundamental importance is that informational patterns can be processed over space and the local matter-energy at the receiving point can be organized to conform to, or comply with, this information
  • the delivery of "flowers by telegraph."
  • Matter-energy and information always flow together
  • Information is always borne on a marker
  • . Conversely there is no regular movement in a system unless there is a difference in potential between two points, which is negative entropy or information
  • If the receiver responds primarily to the material or energic aspect, I shall call it, for brevity, a matter-energy transmission; if the response is primarily to the information, I shall call it an information transmission
  • Moreover, just as living systems must have specific forms of matter-energy, so they must have specific patterns of information
  • example
  • example
  • develop normally
  • have appropriate information inputs in infancy
  • pairs of antonyms
  • one member of which is associated with the concept of information (H)
  • the other member of which is associated with its negative, entropy (S)
  • System
  • A system is a set of interacting units with relationships among them
  • .The word "set" implies that the units have some common properties. These common properties are essential if the units are to interact or have relationships. The state of each unit is constrained by, conditioned by, or dependent on the state of other units. The units are coupled. Moreover, there is at least one measure of the sum of its units which is larger than the sum of that measure of its units.

  • physical proximity of its units
  • similarity of its units
  • common fate of its units
  • distinct or recognizable patterning of its units.
  • Their boundaries are discovered by empirical operations available to the general scientific community rather than set conceptually by a single observer
  • Variable of a concrete system
  • Any property of a unit or relationship within a system which can be recognized by an observer
  • which can potentially change over time, and whose change can potentially be measured by specific operations, is a variable of a concrete system

  • The state of a concrete system
  • its structure
  • represented by the set of values on some scale which its variables have at that instant
  • Open system
  • Most concrete systems have boundaries which are at least partially permeable, permitting sizable magnitudes of at least certain sorts of matter-energy or information transmissions to pass them. Such a system is an open system. In open systems entropy may increase, remain in steady state, or decrease.
  • Closed system
  • impermeable boundaries through which no matter-energy or information transmissions of any sort can occur is a closed system

  • No actual concrete system is completely closed
  • In closed systems, entropy generally increases, exceptions being when certain reversible processes are carried on which do not increase it. It can never decrease.
  • Nonliving system

  • Abstracted versus concrete systems
  • One fundamental distinction between abstracted and concrete systems is that the boundaries of abstracted systems may at times be conceptually established at regions which cut through the units and relationships in the physical space occupied by concrete systems, but the boundaries of these latter systems are always set at regions which include within them all the units and internal relationships of each system
  • A science of abstracted systems certainly is possible and under some conditions may be useful.
  • If the diverse fields of science are to be unified, it would be helpful if all disciplines were oriented either to concrete or to abstracted systems.
  • It is of paramount importance for scientists to distinguish clearly between them

    "Centrifuges are commonly required devices in medical diagnostics facilities as well as scientific laboratories. Although there are commercial and open source centrifuges, the costs of the former and the required electricity to operate the latter limit accessibility in resource-constrained settings. There is a need for low-cost, human-powered, verified, and reliable lab-scale centrifuges. This study provides the designs for a low-cost 100% 3-D printed centrifuge, which can be fabricated on any low-cost RepRap-class (self-replicating rapid prototyper) fused filament fabrication (FFF)- or fused particle fabrication (FPF)-based 3-D printer. In addition, validation procedures are provided using a web camera and free and open source software. This paper provides the complete open source plans, including instructions for the fabrication and operation of a hand-powered centrifuge. This study successfully tested and validated the instrument, which can be operated anywhere in the world with no electricity inputs, obtaining a radial velocity of over 1750 rpm and over 50 N of relative centrifugal force. Using commercial filament, the instrument costs about U.S. $25, which is less than half of all commercially available systems. However, the costs can be dropped further using recycled plastics on open source systems for over 99% savings. The results are discussed in the context of resource-constrained medical and scientific facilities."

smart contract cryptography paper

shared by Kurt Laitner on 21 Mar 13 - No Cached
  • Whether enforced by a government, or otherwise, the contract is the basic building block of a free market economy.
  • A smart contract is a set of promises, specified in digital form, including protocols within which the parties perform on the other promises.
  • The basic idea of smart contracts is that many kinds of contractual clauses (such as liens, bonding, delineation of property rights, etc.) can be embedded in the hardware and software we deal with, in such a way as to make breach of contract expensive (if desired, sometimes prohibitively so) for the breacher.
  • ...77 more annotations...
  • A broad statement of the key idea of smart contracts, then, is to say that contracts should be embedded in the world.
  • And where the vending machine, like electronic mail, implements an asynchronous protocol between the vending company and the customer, some smart contracts entail multiple synchronous steps between two or more parties
  • POS (Point of Sale)
  • EDI (Electronic Data Interchange
  • SWIFT
  • allocation of public network bandwidth via automated auctions
  • Smart contracts reference that property in a dynamic, proactively enforced form, and provide much better observation and verification where proactive measures must fall short.
  • The mechanisms of the world should be structured in such a way as to make the contracts (a) robust against naive vandalism, and (b) robust against sophisticated, incentive compatible (rational) breach.
  • A third category, (c) sophisticated vandalism (where the vandals can and are willing to sacrifice substantial resources), for example a military attack by third parties, is of a special and difficult kind that doesn't often arise in typical contracting, so that we can place it in a separate category and ignore it here.
  • The threat of physical force is an obvious way to embed a contract in the world -- have a judicial system decide what physical steps are to be taken out by an enforcement agency (including arrest, confiscation of property, etc.) in response to a breach of contract
  • It is what I call a reactive form of security.
  • The need to invoke reactive security can be minimized, but not eliminated, by making contractual arrangements verifiable
  • Observation of a contract in progress, in order to detect the first sign of breach and minimize losses, also is a reactive form of security
  • A proactive form of security is a physical mechanism that makes breach expensive
  • From common law, economic theory, and contractual conditions often found in practice, we can distill four basic objectives of contract design
  • observability
  • The disciplines of auditing and investigation roughly correspond with verification of contract performance
  • verifiability
  • The field of accounting is, roughly speaking, primarily concerned with making contracts an organization is involved in more observable
  • privity
  • This is a generalization of the common law principle of contract privity, which states that third parties, other than the designated arbitrators and intermediaries, should have no say in the enforcement of a contract
  • The field of security (especially, for smart contracts, computer and network security), roughly corresponds to the goal of privity.
  • enforceability
  • Reputation, built-in incentives, "self-enforcing" protocols, and verifiability can all play a strong part in meeting the fourth objective
  • Smart contracts often involve trusted third parties, exemplified by an intermediary, who is involved in the performance, and an arbitrator, who is invoked to resolve disputes arising out of performance (or lack thereof)
  • In smart contract design we want to get the most out of intermediaries and arbitrators, while minimizing exposure to them
  • Legal barriers are the most severe cost of doing business across many jurisdictions. Smart contracts can cut through this Gordian knot of jurisdictions
  • Where smart contracts can increase privity, they can decrease vulnerability to capricious jurisdictions
  • Secret sharing
  • The field of Electronic Data Interchange (EDI), in which elements of traditional business transactions (invoices, receipts, etc.) are exchanged electronically, sometimes including encryption and digital signature capabilities, can be viewed as a primitive forerunner to smart contracts
  • One important task of smart contracts, that has been largely overlooked by traditional EDI, is critical to "the meeting of the minds" that is at the heart of a contract: communicating the semantics of the protocols to the parties involved
  • There is ample opportunity in smart contracts for "smart fine print": actions taken by the software hidden from a party to the transaction.
  • Thus, via hidden action of the software, the customer is giving away information they might consider valuable or confidential, but the contract has been drafted, and transaction has been designed, in such a way as to hide those important parts of that transaction from the customer.
  • To properly communicate transaction semantics, we need good visual metaphors for the elements of the contract. These would hide the details of the protocol without surrendering control over the knowledge and execution of contract terms
  • Protocols based on mathematics, called cryptographic protocols, tre the basic building blocks that implement the improved tradeoffs between observability, verifiability, privity, and enforceability in smart contracts
  • secret key cryptography,
  • Public key cryptography
  • digital signatures
  • blind signature
  • Where smart contracts can increase observability or verifiability, they can decrease dependence on these obscure local legal codes and enforcement traditions
  • zero-knowledge interactive proof
  • digital mix
  • Keys are not necessarily tied to identities, and the task of doing such binding turns out to be more difficult than at first glance.
  • All public key operation are are done inside an unreadable hardware board on a machine with a very narrow serial-line connection (ie, it carries only a simple single-use protocol with well-verified security) to a dedicated firewall. Such a board is available, for example, from Kryptor, and I believe Viacrypt may also have a PGP-compatable board. This is economical for central sites, but may be less practical for normal users. Besides better security, it has the added advantage that hardware speeds up the public key computations.
  • If Mallet's capability is to physically sieze the machine, a weaker form of key protection will suffice. The trick is to hold the keys in volatile memory.
  • The data is still vulnerable to a "rubber hose attack" where the owner is coerced into revealing the hidden keys. Protection against rubber hose attacks might require some form of Shamir secret sharing which splits the keys between diverse phgsical sites.
  • How does Alice know she has Bob's key? Who, indeed, can be the parties to a smart contract? Can they be defined just by their keys? Do we need biometrics (such as autographs, typed-in passwords, retina scans, etc.)?
  • The public key cryptography software package "Pretty Good Privacy" (PGP) uses a model called "the web of trust". Alice chooses introducers whom she trusts to properly identify the map between other people and their public keys. PGP takes it from there, automatically validating any other keys that have been signed by Alice's designated introducers.
  • 1) Does the key actually belong to whom it appears to belong? In other words, has it been certified with a trusted signature?
  • 2) Does it belong to an introducers, someone you can trust to certify other keys?
  • 3) Does the key belong to someone you can trust to introduce other introducers? PGP confuses this with criterion (2). It is not clear that any single person has enough judgement to properly undertake task (3), nor has a reasonable institution been proposed that will do so. This is one of the unsolved problems in smart contracts.
  • PGP also can be given trust ratings and programmed to compute a weighted score of validity-- for example, two marginally trusted signatures might be considered as credible as one fully trusted signature
  • Notaries Public Two different acts are often called "notarization". The first is simply where one swears to the truth of some affidavit before a notary or some other officer entitled to take oaths. This does not require the notary to know who the affiant is. The second act is when someone "acknowledges" before a notary that he has executed a document as ``his own act and deed.'' This second act requires the notary to know the person making the acknowledgment.
  • "Identity" is hardly the only thing we might want map to a key. After all, physical keys we use for our house, car, etc. are not necessarily tied to our identity -- we can loan them to trusted friends and relatives, make copies of them, etc. Indeed, in cyberspace we might create "virtual personae" to reflect such multi-person relationships, or in contrast to reflect different parts of our personality that we do not want others to link. Here is a possible classification scheme for virtual personae, pedagogically presented:
  • A nym is an identifier that links only a small amount of related information about a person, usually that information deemed by the nym holder to be relevant to a particular organization or community
  • A nym may gain reputation within its community.
  • With Chaumian credentials, a nym can take advantage of the positive credentials of the holder's other nyms, as provably linked by the is-a-person credential
  • A true name is an identifier that links many different kinds of information about an person, such as a full birth name or social security number
  • As in magick, knowing a true name can confer tremendous power to one's enemies
  • A persona is any perstient pattern of behavior, along with consistently grouped information such as key(s), name(s), network address(es), writing style, and services provided
  • A reputable name is a nym or true name that has a good reputation, usually because it carries many positive credentials, has a good credit rating, or is otherwise highly regarded
  • Reputable names can be difficult to transfer between parties, because reputation assumes persistence of behavior, but such transfer can sometimes occur (for example, the sale of brand names between companies).
  • Blind signatures can be used to construct digital bearer instruments, objects identified by a unique key, and issued, cleared, and redeemed by a clearing agent.
  • The clearing agent prevents multiple clearing of particular objects, but can be prevented from linking particular objects one or both of the clearing nyms who transferred that object
  • These instruments come in an "online" variety, cleared during every transfer, and thus both verifiable and observable, and an "offline" variety, which can be transfered without being cleared, but is only verifiable when finally cleared, by revealing any the clearing nym of any intermediate holder who transfered the object multiple times (a breach of contract).
  • To implement a full transaction of payment for services, we need more than just the digital cash protocol; we need a protocol that guarantees that service will be rendered if payment is made, and vice versa
  • A credential is a claim made by one party about another. A positive credential is one the second party would prefer to reveal, such as a degree from a prestigious school, while that party would prefer not to reveal a negative credential such as a bad credit rating.
  • A Chaumian credential is a cryptographic protocol for proving one possesses claims made about onself by other nyms, without revealing linkages between those nyms. It's based around the is-a-person credential the true name credential, used to prove the linkage of otherwise unlinkable nyms, and to prevent the transfer of nyms between parties.
  • Another form of credential is bearer credential, a digital bearer instrument where the object is a credential. Here the second party in the claim refers to any bearer -- the claim is tied only to the reputable name of issuing organization, not to the nym or true name of the party holding the credential.
  • Smart Property We can extend the concept of smart contracts to property. Smart property might be created by embedding smart contracts in physical objects. These embedded protocols would automatically give control of the keys for operating the property to the party who rightfully owns that property, based on the terms of the contract. For example, a car might be rendered inoperable unless the proper challenge-response protocol is completed with its rightful owner, preventing theft. If a loan was taken out to buy that car, and the owner failed to make payments, the smart contract could automatically invoke a lien, which returns control of the car keys to the bank. This "smart lien" might be much cheaper and more effective than a repo man. Also needed is a protocol to provably remove the lien when the loan has been paid off, as well as hardship and operational exceptions. For example, it would be rude to revoke operation of the car while it's doing 75 down the freeway.
  • Smart property is software or physical devices with the desired characteristics of ownership embedded into them; for example devices that can be rendered of far less value to parties who lack possesion of a key, as demonstrated via a zero knowledge interactive proof
  • One method of implementing smart property is thru operation necessary data (OND): data necessary to the operation of smart property.
  • A smart lien is the sharing of a smart property between parties, usually two parties called the owner and the lienholder.
  • Many parties, especially new entrants, may lack this reputation capital, and will thus need to be able to share their property with the bank via secure liens
  • What about extending the concept of contract to cover agreement to a prearranged set of tort laws? These tort laws would be defined by contracts between private arbitration and enforcement agencies, while customers would have a choice of jurisdictions in this system of free-market "governments".
  • If these privately practiced law organizations (PPLs for short) bear ultimate responsibility for the criminal activities of their customers, or need to insure lack of defection or future payments on the part of customers, they may in turn ask for liens against their customers, either in with contractual terms allowing arrest of customers under certain conditions
  • Other important areas of liability include consumer liability and property damage (including pollution). There need to mechanisms so that, for example, pollution damage to others' persons or property can be assessed, and liens should exist so that the polluter can be properly charged and the victims paid. Where pollution is quantifiable, as with SO2 emissions, markets can be set up to trade emission rights. The PPLs would have liens in place to monitor their customer's emissions and assess fees where emission rights have been exceeded.

  • I clarify the core elements of cryptocurrency and outline a different approach to designing such currencies rooted in biomimicry
  • This post outlines a completely different strategy for implementing cryptocurrencies with completely distributed chains
  • Rather than trying to make one global, anonymous, digital cash
  • ...95 more annotations...
  • we are interested in the resilience that comes from building a rich ecosystem of interoperable currencies
  • What are the core elements of a modern cryptocurrency?
  • Digital
  • Holdings are electronic and only exist and operate by virtue of a community’s agreement about how to interpret digital bits according to rules about operation and accounting of the currency.
  • Trustless
  • don’t have to trust a 3rd party central authority
  • Decentralized
  • Specifically, access, issuance, transaction accounting, rules & policies, should be collectively visible, known, and held.
  • Cryptographic
  • This cryptographic structure is used to enable a variety of people to host the data without being able to alter it.
  • Identity
  • there must be a way to associate these bits with some kind of account, wallet, owner, or agent who can use them
  • Other things that many take for granted in blockchains may not be core but subject to decisions in design and implementation, so they can vary between implementations
  • It does not have to be stored in a synchronized global ledger
  • does not have to be money. It may be a reputation currency, or data used for identity, or naming, etc
  • Its units do not have to be cryptographic tokens or coins
  • It does not have to protect the anonymity of users, although it may
  • if you think currency is only money, and that money must be artificially scarce
  • Then you must tackle the problem of always tracking which coins exist, and which have been spent. That is one approach — the one blockchain takes.
  • You might optimize for anonymity if you think of cryptocurrency as a tool to escape governments, regulations, and taxes.
  • if you want to establish and manage membership in new kinds of commons, then identity and accountability for actions may turn out to be necessary ingredients instead of anonymity.
  • In the case of the MetaCurrency Project, we are trying to support many use cases by building tools to enable a rich ecosystem of communities and current-sees (many are non-monetary) to enhance collective intelligence at all scales.
  • Managing consensus about a shared reality is a central challenge at the heart of all distributed computing solutions.
  • If we want to democratize money by having cryptocurrencies become a significant and viable means of transacting on a daily basis, I believe we need fundamentally more scalable approaches that don’t require expensive, dedicated hardware just to participate.
  • We should not need system wide consensus for two people to do a transaction in a cryptocurrency
  • Blockchain is about managing a consensus about what was “said.” Ceptr is about distributing a consensus about how to “speak.”
  • how nature gets the job done in massively scalable systems which require coordination and consistency
  • Replicate the same processes across all nodes
  • Empower every node with full agency
  • Hold this transformed state locally and reliably
  • Establish protocols for interaction
  • Each speaker of a language carries the processes to understand sentences they hear, and generate sentences they need
  • we certainly don’t carry some kind of global ledger of everything that’s ever been said, or require consensus about what has been said
  • Language IS a communication protocol we learn by emulating the processes of usage.
  • Dictionaries try to catch up when the usage
  • there is certainly no global ledger with consensus about the state of trillions of cells. Yet, from a single zygote’s copy of DNA, our cells coordinate in a highly decentralized manner, on scales of trillions, and without the latency or bottlenecks of central control.
  • Imagine something along the lines of a Java Virtual Machine connected to a distributed version of Github
  • Every time this JVM runs a program it confirms the hash of the code it is about to execute with the hash signed into the code repository by its developers
  • This allows each node that intends to be honest to be sure that they’re running the same processes as everyone else. So when two parties want to do a transaction, and each can have confidence their own code, and the results that your code produces
  • Then you treat it as authoritative and commit it to your local cryptographically self-validating data store
  • Allowing each node to treat itself as a full authority to process transactions (or interactions via shared protocols) is exactly how you empower each node with full agency. Each node runs its copy of the signed program/processes on its own virtual machine, taking the transaction request combined with the transaction chains of the parties to the transaction. Each node can confirm their counterparty’s integrity by replaying their transactions to produce their current state, while confirming signatures and integrity of the chain
  • If both nodes are in an appropriate state which allows the current transaction, then they countersign the transaction and append to their respective chains. When you encounter a corrupted or dishonest node (as evidenced by a breach of integrity of their chain — passing through an invalid state, broken signatures, or broken links), your node can reject the transaction you were starting to process. Countersigning allows consensus at the appropriate scale of the decision (two people transacting in this case) to lock data into a tamper-proof state so it can be stored in as many parallel chains as you need.
  • When your node appends a mutually validated and signed transaction to its chain, it has updated its local state and is able to represent the integrity of its data locally. As long as each transaction (link in the chain) has valid linkages and countersignatures, we can know that it hasn’t been tampered with.
  • If you can reliably embody the state of the node in the node itself using Intrinsic Data Integrity, then all nodes can interact in parallel, independent of other interactions to maximize scalability and simultaneous processing. Either the node has the credits or it doesn’t. I don’t have to refer to a global ledger to find out, the state of the node is in the countersigned, tamper-proof chain.
  • Just like any meaningful communication, a protocol needs to be established to make sure that a transaction carries all the information needed for each node to run the processes and produce a new signed and chained state. This could be debits or credits to an account which modify the balance, or recoding courses and grades to a transcript which modify a Grade Point Average, or ratings and feedback contributing to a reputation score, and so on.
  • By distributing process at the foundation, and leveraging Intrinsic Data Integrity, our approach results in massive improvements in throughput (from parallel simultaneous independent processing), speed, latency, efficiency, and cost of hardware.
  • You also don’t need to incent people to hold their own record — they already want it.
  • Another noteworthy observation about humans, cells, and atoms, is that each has a general “container” that gets configured to a specific use.
  • Likewise, the Receptors we’ve built are a general purpose framework which can load code for different distributed applications. These Receptors are a lightweight processing container for the Ceptr Virtual Machine Host
  • Ceptr enables a developer to focus on the rules and transactions for their use case instead of building a whole framework for distributed applications.
  • how units in a currency are issued
  • Most people think that money is just money, but there are literally hundreds of decisions you can make in designing a currency to target particular needs, niches, communities or patterns of flow.
  • Blockchain cryptocurrencies are fiat currencies. They create tokens or coins from nothing
  • These coins are just “spoken into being”
  • the challenging task of
  • ensure there is no counterfeiting or double-spending
  • Blockchain cryptocurrencies are fiat currencies
  • These coins are just “spoken into being”
  • the challenging task of tracking all the coins that exist to ensure there is no counterfeiting or double-spending
  • You wouldn’t need to manage consensus about whether a cryptocoin is spent, if your system created accounts which have normal balances based on summing their transactions.
  • In a mutual credit system, units of currency are issued when a participant extends credit to another user in a standard spending transaction
  • Alice pays Bob 20 credits for a haircut. Alice’s account now has -20, and Bob’s has +20.
  • Alice spent credits she didn’t have! True
  • Managing the currency supply in a mutual credit system is about managing credit limits — how far people can spend into a negative balance
  • Notice the net number units in the system remains zero
  • One elegant approach to managing mutual credit limits is to set them based on actual demand.
  • concerns about manufacturing fake accounts to game credit limits (Sybil Attacks)
  • keep in mind there can be different classes of accounts. Easy to create, anonymous accounts may get NO credit limit
  • What if I alter my code to give myself an unlimited credit limit, then spend as much as I want? As soon as you pass the credit limit encoded in the shared agreements, the next person you transact with will discover you’re in an invalid state and refuse the transaction.
  • If two people collude to commit an illegal transaction by both hacking their code to allow a normally invalid state, the same still pattern still holds. The next person they try to transact with using untampered code will detect the problem and decline to transact.
  • Most modern community currency systems have been implemented as mutual credit,
  • Hawala is a network of merchants and businessmen, which has been operating since the middle ages, performing money transfers on an honor system and typically settling balances through merchandise instead of transferring money
  • Let’s look at building a minimum viable cryptocurrency with the hawala network as our use case
  • To minimize key management infrastructure, each hawaladar’s public key is their address or identity on the network. To join the network you get a copy of the software from another hawaladar, generate your public and private keys, and complete your personal profile (name, location, contact info, etc.). You call, fax, or email at least 10 hawaladars who know you, and give them your IP address and ask them to vouch for you.
  • Once 10 other hawaladars have vouched for you, you can start doing other transactions because the protocol encoded in every node will reject a transaction chain that doesn’t start with at least 10 vouches
  • seeding your information with those other peers so you can be found by the rest of the network.
  • As described in the Mutual Credit section, at the time of transaction each party audits the counterparty’s transaction chain.
  • Our hawala crypto-clearinghouse protocol has two categories of transactions: some used for accounting and others for routing. Accounting transactions change balances. Routing transactions maintain network integrity by recording information about hawaladar
  • Accounting Transactions create signed data that changes account balances and contains these fields:
  • The final hash of all of the above fields is used as a unique transaction ID and is what each of party signs with their private keys. Signing indicates a party has agreed to the terms of the transaction. Only transactions signed by both parties are considered valid. Nodes can verify signatures by confirming that decryption of the signature using the public key yields a result which matches the transaction ID.
  • Routing Transactions sign data that changes the peers list and contain these fields:
  • As with accounting transactions, the hash of the above fields is used as the transaction’s unique key and the basis for the cryptographic signature of both counterparties.
  • Remember, instead of making changes to account balances, routing transactions change a node’s local list of peers for finding each other and processing.
  • a distributed network of mutual trust
  • operates across national boundaries
  • everyone already keeps and trusts their own separate records
  • Hawaladars are not anonymous
  • “double-spending”
  • It would be possible for someone to hack the code on their node to “forget” their most recent transaction (drop the head of their chain), and go back to their previous version of the chain before that transaction. Then they could append a new transaction, drop it, and append again.
  • After both parties have signed the agreed upon transaction, each party submits the transaction to separate notaries. Notaries are a special class of participant who validate transactions (auditing each chain, ensuring nobody passes through an invalid state), and then they sign an outer envelope which includes the signatures of the two parties. Notaries agree to run high-availability servers which collectively manage a Distributed Hash Table (DHT) servicing requests for transaction information. As their incentive for providing this infrastructure, notaries get a small transaction fee.
  • This approach introduces a few more steps and delays to the transaction process, but because it operates on independent parallel chains, it is still orders of magnitude more efficient and decentralized than reaching consensus on entries in a global ledger
  • millions of simultaneous transactions could be getting processed by other parties and notaries with no bottlenecks.
  • There are other solutions to prevent nodes from dropping the head of their transaction chain, but the approach of having notaries serve out a DHT solves a number of common objections to completely distributed accounting. Having access to reliable lookups in a DHT provides a similar big picture view that you get from a global ledger. For example, you may want a way to look up transactions even when the parties to that transaction are offline, or to be able to see the net system balance at a particular moment in time, or identify patterns of activity in the larger system without having to collect data from everyone individually.
  • By leveraging Intrinsic Data Integrity to run numerous parallel tamper-proof chains you can enable nodes to do various P2P transactions which don’t actually require group consensus. Mutual credit is a great way to implement cryptocurrencies to run in this peered manner. Basic PKI with a DHT is enough additional infrastructure to address main vulnerabilities. You can optimize your solution architecture by reserving reserve consensus work for tasks which need to guarantee uniqueness or actually involve large scale agreement by humans or automated contracts.
  • It is not only possible, but far more scalable to build cryptocurrencies without a global ledger consensus approach or cryptographic tokens.

    Machines talking to machines No doubt that the Olympics will have a profound effect in shaping London's future. By the time the Games begin, for instance, it will have Europe's largest free WiFi zone, with the city's iconic red phone booths converted, fittingly, into hotspots. But another opportunity London landed earlier this month could have just as much impact, perhaps more. A company called Living PlanIt announced that it will begin testing its "Urban Operating System" in the Greenwich section of the city. What does that mean? Put simply, London would have its own operating system, much as your PC runs on Windows or your Mac runs on Apple's IOS. This ties into the latest hot buzz phrase, "the internet of things," which describes a world where machines talk to other machines. No human interaction required. So, for a city, this means sensors in buildings would connect to sensors in water treatment plants which would connect to sensors in stoplights. It would be one gigantic, computerized urban nervous system, which a lot of experts think is the only way cities can survive a future when they'll contain more than two out of every three people on Earth. Based on what sensors reveal about the location and movement of humans in a section of a city, for instance, buildings will automatically adjust their temperatures, streetlights will dim or brighten, water flow will increase or slow. Or, in the event of a disaster, emergency services would have real-time access to traffic data, trauma unit availability, building blueprints. And soon enough, our smart phones will be able to tap in to the Urban OS. So will our household appliances. This is not some 21st century analogue of the personal jet pack. The Urban OS is the driving force behind a smart city being built from the ground up in northern Portugal. Construction is scheduled to be completed in three years; eventually it will have about 150,000 residents. It will also have more than 100 million sen

  • The act of accessing may mean consuming, entering, or using.
  • Permission to access a resource is called authorization.
  • Locks and login credentials are two analogous mechanisms of access control.
  • ...26 more annotations...
  • Geographical access control may be enforced by personnel (e.g., border guard, bouncer, ticket checker)
  • n alternative of access control in the strict sense (physically controlling access itself) is a system of checking authorized presence, see e.g. Ticket controller (transportation). A variant is exit control, e.g. of a shop (checkout) or a country
  • access control refers to the practice of restricting entrance to a property, a building, or a room to authorized persons
  • can be achieved by a human (a guard, bouncer, or receptionist), through mechanical means such as locks and keys, or through technological means such as access control systems like the mantrap.
  • Physical access control is a matter of who, where, and when
  • Historically, this was partially accomplished through keys and locks. When a door is locked, only someone with a key can enter through the door, depending on how the lock is configured. Mechanical locks and keys do not allow restriction of the key holder to specific times or dates. Mechanical locks and keys do not provide records of the key used on any specific door, and the keys can be easily copied or transferred to an unauthorized person. When a mechanical key is lost or the key holder is no longer authorized to use the protected area, the locks must be re-keyed.[citation needed] Electronic access control uses computers to solve the limitations of mechanical locks and keys. A wide range of credentials can be used to replace mechanical keys. The electronic access control system grants access based on the credential presented. When access is granted, the door is unlocked for a predetermined time and the transaction is recorded. When access is refused, the door remains locked and the attempted access is recorded. The system will also monitor the door and alarm if the door is forced open or held open too long after being unlocked
  • Credential
  • Access control system operation
  • The above description illustrates a single factor transaction. Credentials can be passed around, thus subverting the access control list. For example, Alice has access rights to the server room, but Bob does not. Alice either gives Bob her credential, or Bob takes it; he now has access to the server room. To prevent this, two-factor authentication can be used. In a two factor transaction, the presented credential and a second factor are needed for access to be granted; another factor can be a PIN, a second credential, operator intervention, or a biometric input
  • There are three types (factors) of authenticating information:[2] something the user knows, e.g. a password, pass-phrase or PIN something the user has, such as smart card or a key fob something the user is, such as fingerprint, verified by biometric measurement
  • Passwords are a common means of verifying a user's identity before access is given to information systems. In addition, a fourth factor of authentication is now recognized: someone you know, whereby another person who knows you can provide a human element of authentication in situations where systems have been set up to allow for such scenarios
  • When a credential is presented to a reader, the reader sends the credential’s information, usually a number, to a control panel, a highly reliable processor. The control panel compares the credential's number to an access control list, grants or denies the presented request, and sends a transaction log to a database. When access is denied based on the access control list, the door remains locked.
  • A credential is a physical/tangible object, a piece of knowledge, or a facet of a person's physical being, that enables an individual access to a given physical facility or computer-based information system. Typically, credentials can be something a person knows (such as a number or PIN), something they have (such as an access badge), something they are (such as a biometric feature) or some combination of these items. This is known as multi-factor authentication. The typical credential is an access card or key-fob, and newer software can also turn users' smartphones into access devices.
  • An access control point, which can be a door, turnstile, parking gate, elevator, or other physical barrier, where granting access can be electronically controlled. Typically, the access point is a door. An electronic access control door can contain several elements. At its most basic, there is a stand-alone electric lock. The lock is unlocked by an operator with a switch. To automate this, operator intervention is replaced by a reader. The reader could be a keypad where a code is entered, it could be a card reader, or it could be a biometric reader. Readers do not usually make an access decision, but send a card number to an access control panel that verifies the number against an access list
  • monitor the door position
  • Generally only entry is controlled, and exit is uncontrolled. In cases where exit is also controlled, a second reader is used on the opposite side of the door. In cases where exit is not controlled, free exit, a device called a request-to-exit (REX) is used. Request-to-exit devices can be a push-button or a motion detector. When the button is pushed, or the motion detector detects motion at the door, the door alarm is temporarily ignored while the door is opened. Exiting a door without having to electrically unlock the door is called mechanical free egress. This is an important safety feature. In cases where the lock must be electrically unlocked on exit, the request-to-exit device also unlocks the doo
  • Access control topology
  • Access control decisions are made by comparing the credential to an access control list. This look-up can be done by a host or server, by an access control panel, or by a reader. The development of access control systems has seen a steady push of the look-up out from a central host to the edge of the system, or the reader. The predominant topology circa 2009 is hub and spoke with a control panel as the hub, and the readers as the spokes. The look-up and control functions are by the control panel. The spokes communicate through a serial connection; usually RS-485. Some manufactures are pushing the decision making to the edge by placing a controller at the door. The controllers are IP enabled, and connect to a host and database using standard networks
  • Access control readers may be classified by the functions they are able to perform
  • and forward it to a control panel.
  • Basic (non-intelligent) readers: simply read
  • Semi-intelligent readers: have all inputs and outputs necessary to control door hardware (lock, door contact, exit button), but do not make any access decisions. When a user presents a card or enters a PIN, the reader sends information to the main controller, and waits for its response. If the connection to the main controller is interrupted, such readers stop working, or function in a degraded mode. Usually semi-intelligent readers are connected to a control panel via an RS-485 bus.
  • Intelligent readers: have all inputs and outputs necessary to control door hardware; they also have memory and processing power necessary to make access decisions independently. Like semi-intelligent readers, they are connected to a control panel via an RS-485 bus. The control panel sends configuration updates, and retrieves events from the readers.
  • Systems with IP readers usually do not have traditional control panels, and readers communicate directly to a PC that acts as a host

  • Some readers may have additional features such as an LCD and function buttons for data collection purposes (i.e. clock-in/clock-out events for attendance reports), camera/speaker/microphone for intercom, and smart card read/write support

  • VC-backed sharing economy companies like Airbnb and Uber have caused trouble for legacy industries, but gone is the illusion that they are doing it with actual sharing
  • Their main contribution to society has been facilitating new kinds of transactions
  • The notion that sharing would do away with the need for owning has been one of the mantras of sharing economy promoters. We could share cars, houses, and labor, trusting in the platforms to provide. But it’s becoming clear that ownership matters as much as ever.

  • Léonard and his collaborators are part of a widespread effort to make new kinds of ownership the new norm. There are cooperatives, networks of freelancers, cryptocurrencies, and countless hacks in between. Plans are being made for a driver-owned Lyft, a cooperative version of eBay, and Amazon Mechanical Turk workers are scheming to build a crowdsourcing platform they can run themselves. Each idea has its prospects and shortcomings, but together they aspire toward an economy, and an Internet, that is more fully ours.
  • Jeremy Rifkin, a futurist to CEOs and governments, contends that the Internet-of-things and 3-D printers are ushering in a “ zero marginal cost society“ in which the “collaborative commons” will be more competitive than extractive corporations
  • once the VC-backed sharing companies clear away regulatory hurdles, local co-ops will be poised to swoop in and spread the wealth
  • People are recognizing that doing business differently will require changing who gets to own what.
  • “We’re moving into a new economic age,” says Marjorie Kelly, who spent two decades at the helm of Business Ethics magazine and now advises social entrepreneurs. “It needs to be sustainable. It needs to be inclusive. And the foundation of what defines an economic age is its form of ownership.”
  • It’s a worker-owned cooperative that produces open-source software to help people practice consensus—though they prefer the term “collaboration”—about decisions that affect their lives.
  • From the start Loomio was part of Enspiral, an “open value network“ of freelancers and social enterprises devoted to mutual support and the common good.

  • The team members recently had to come to terms with the fact that, for the time being, only some of them could be paid for full-time work They called the process “participatory downsizing.”
  • And they can take many forms. Loomio and other tech companies, for instance, are aspiring toward the model of a multi-stakeholder cooperative—one in which not just workers or consumers are voting members, but several such groups at once.
  • Loconomics is a San Francisco-based startup designed, like TaskRabbit, to manage short-term freelance jobs
  • “People who have been without for a long time,” she says, “often operate with a mindset that they can’t share what they have, because they don’t know when that resource will come along again.”
  • As Loconomics prepares to begin operations this winter, it’s running out of the pocket of the founder, Josh Danielson

  • Fenton’s new undertaking, Sovolve, proposes to “create innovative solutions to accelerate social change,” much as CouchSurfing did, but it’s doing the innovating cautiously. All work is done by worker-owners located around the world. Sovolve uses an internal platform—soon to become a product in its own right—through which contributors decide how much they want to be paid in cash and how much in equity. They can see how much others are earning. Their virtual workplace is gamified, with everyone working to nudge their first product, WonderApp, into virality

  • Open-source software and share-alike licenses have revived the ancient idea of the commons for an Internet age. But the “ commons-based peer production“ that Sensorica seeks to practice doesn’t arise overnight. Just as today’s business culture rests on generations of accumulated law, habit, and training, learning to manage a commons successfully takes time

  • A project called Eris is developing a collective decision-making tool designed to govern DAOs on Ethereum, though the platform may still be months from release.
  • For now, the burden of reinventing every wheel at once makes it hard for companies like Sensorica and Loomio to compete
  • For instance, Cutting Edge Capital specializes in helping companies raise money through a long-standing mechanism called the direct public investment, or DPO, which allows for small, non-accredited investors.
  • Venture funding may be in competition with Dietz’s cryptoequity vision, but it provides a fearsome head start
  • Co-ops help ensure that the people who contribute to and depend on an enterprise keep control and keep profits, so they’re a possible remedy for worsening economic inequality
  • Sooner or later, transforming a system of gross inequality and concentrated wealth will require more than isolated experiments at the fringes—it will require capturing that wealth and redirecting its flows
  • A less consensual strategy was employed to fund the Catalan Integral Cooperative in Spain; over the course of a few years, one activist borrowed around $600,000 from Spanish banks without paying any of it back.
  • In Jackson, Mississippi, Chokwe Lumumba was elected mayor in 2013 on a platform of fostering worker-owned cooperatives, although much of the momentum was lost when Lumumba died just a few months later.

valve management structure company paper

shared by Kurt Laitner on 07 Aug 12 - No Cached
  • Valve’s management model; one in which there are no bosses, no delegation, no commands, no attempt by anyone to tell someone what to do
  • Every social order, including that of ants and bees, must allocate its scarce resources between different productive activities and processes, as well as establish patterns of distribution among individuals and groups of output collectively produced.
  • the allocation of resources, as well as the distribution of the produce, is based on a decentralised mechanism functioning by means of price signals:
  • ...18 more annotations...
  • Interestingly, however, there is one last bastion of economic activity that proved remarkably resistant to the triumph of the market: firms, companies and, later, corporations. Think about it: market-societies, or capitalism, are synonymous with firms, companies, corporations. And yet, quite paradoxically, firms can be thought of as market-free zones. Within their realm, firms (like societies) allocate scarce resources (between different productive activities and processes). Nevertheless they do so by means of some non-price, more often than not hierarchical, mechanism!
  • they are the last remaining vestiges of pre-capitalist organisation within… capitalism
  • The miracle of the market, according to Hayek, was that it managed to signal to each what activity is best for herself and for society as a whole without first aggregating all the disparate and local pieces of knowledge that lived in the minds and subconscious of each consumer, each designer, each producer. How does this signalling happen? Hayek’s answer (borrowed from Smith) was devastatingly simple: through the movement of prices
  • The idea of spontaneous order comes from the Scottish Enlightenment, and in particular David Hume who, famously, argued against Thomas Hobbes’ assumption that, without some Leviathan ruling over us (keeping us “all in awe”), we would end up in a hideous State of Nature in which life would be “nasty, brutish and short”
  • Hume’s counter-argument was that, in the absence of a system of centralised command, conventions emerge that minimise conflict and organise social activities (including production) in a manner that is most conducive to the Good Life
  • Hayek’s argument was predicated upon the premise that knowledge is always ‘local’ and all attempts to aggregate it are bound to fail. The world, in his eyes, is too complex for its essence to be distilled in some central node; e.g. the state.
  • The idea here is that, through this ever-evolving process, people’s capacities, talents and ideas are given the best chance possible to develop and produce synergies that promote the Common Good. It is as if an invisible hand guides Valve’s individual members to decisions that both unleash each person’s potential and serve the company’s collective interest (which does not necessarily coincide with profit maximisation).
  • Valve differs in that it insists that its employees allocate 100% of their time on projects of their choosing
  • In contrast, Smith and Hayek concentrate their analysis on a single passion: the passion for profit-making
  • Hume also believed in a variety of signals, as opposed to Hayek’s exclusive reliance on price signalling
  • One which, instead of price signals, is based on the signals Valve employees emit to one another by selecting how to allocate their labour time, a decision that is bound up with where to wheel their tables to (i.e. whom to work with and on what)
  • He pointed out simply and convincingly that the cost of subcontracting a good or service, through some market, may be much larger than the cost of producing that good or service internally. He attributed this difference to transactions costs and explained that they were due to the costs of bargaining (with contractors), of enforcing incomplete contracts (whose incompleteness is due to the fact that some activities and qualities cannot be fully described in a written contract), of imperfect monitoring and asymmetrically distributed information, of keeping trade secrets… secret, etc. In short, contractual obligations can never be perfectly stipulated or enforced, especially when information is scarce and unequally distributed, and this gives rise to transaction costs which can become debilitating unless joint production takes place within the hierarchically structured firm. Optimal corporation size corresponds, in Coase’s scheme of things, to a ‘point’ where the net marginal cost of contracting out a service or good (including transaction costs) tends to zero 
  • As Coase et al explained in the previous section, the whole point about a corporation is that its internal organisation cannot turn on price signals (for if it could, it would not exist as a corporation but would, instead, contract out all the goods and services internally produced)
  • Each employee chooses (a) her partners (or team with which she wants to work) and (b) how much time she wants to devote to various competing projects. In making this decision, each Valve employee takes into account not only the attractiveness of projects and teams competing for their time but, also, the decisions of others.
  • Hume thought that humans are prone to all sorts of incommensurable passions (e.g. the passion for a video game, the passion for chocolate, the passion for social justice) the pursuit of which leads to many different types of conventions that, eventually, make up our jointly produced spontaneous order
  • Valve is, at least in one way, more radical than a traditional co-operative firm. Co-ops are companies whose ownership is shared equally among its members. Nonetheless, co-ops are usually hierarchical organisations. Democratic perhaps, but hierarchical nonetheless. Managers may be selected through some democratic or consultative process involving members but, once selected, they delegate and command their ‘underlings’ in a manner not at all dissimilar to a standard corporation. At Valve, by contrast, each person manages herself while teams operate on the basis of voluntarism, with collective activities regulated and coordinated spontaneously via the operations of the time allocation-based spontaneous order mechanism described above.
  • In contrast, co-ops and Valve feature peer-based systems for determining the distribution of a firm’s surplus among employees.
  • There is one important aspect of Valve that I did not focus on: the link between its horizontal management structure and its ‘vertical’ ownership structure. Valve is a private company owned mostly by few individuals. In that sense, it is an enlightened oligarchy: an oligarchy in that it is owned by a few and enlightened in that those few are not using their property rights to boss people around. The question arises: what happens to the alternative spontaneous order within Valve if some or all of the owners decide to sell up?

property governance paper

shared by Kurt Laitner on 03 Feb 14 - No Cached
  • Whenever a group of people depend on a resource that everybody uses but nobody owns, and where one person’s use effects another person’s ability to use the resource, either the population fails to provide the resource, overconsumes and/or fails to replenish it, or they construct an institution for undertaking and managing collective action.
  • Common-pool resources may be owned by national, regional, or local [1]governments; by [2] communal groups; by [3] private individuals or corporations; or used as open access resources by whomever can gain access
  • Based on her survey, Ostrom distilled this list of common design principles from the experience of successful governance institutions: Clearly defined boundaries. Individuals or households who have rights to withdraw resource units from the CPR must be clearly defined, as must the boundaries of the CPR itself. Congruence between appropriation and provision rules and local conditions. Appropriation rules restricting time, place, technology, and/or quantity of resource units are related to local conditions and to provision rules requiring labour, material, and/or money. Collective-choice arrangements. Most individuals affected by the operational rules can participate in modifying the operational rules [how refreshing. Standing!]. Monitoring. Monitors, who actively audit CPR conditions and appropriator behavior, are accountable to the appropriators or are the appropriators. Graduated sanctions. Appropriators who violate operational rules are likely to be assessed graduated sanctions (depending on the seriousness and context of the offence) by other appropriators, by officials accountable to these appropriators, or by both. Conflict-resolution mechanisms. Appropriators and their officials have rapid access to low-cost local arenas to resolve conflicts among appropriators or between appropriators and officials. Minimal recognition of rights to organize. The rights of appropriators to devise their own institutions are not challenged by external governmental authorities. For CPRs that are parts of larger systems: Nested enterprises. Appropriation, provision, monitoring, enforcement, conflict resolution, and governance activities are organized in multiple layers of nested enterprises.

    "Three-axis distributed fiber optic strain measurement in 3D woven composite structures   Paper 8690-6 Time: 1:50 PM - 2:10 PM Author(s): Matt Castellucci, Evan M. Lally, Sandra Klute, Luna Innovations Inc. (United States); David Lowry, NASA Johnson Space Ctr. (United States) Hide Abstract Add to My Schedule  Recent advancements in composite materials technologies have broken further from traditional designs and require advanced instrumentation and analysis capabilities. Success or failure is highly dependent on design analysis and manufacturing processes. By monitoring smart structures throughout manufacturing and service life, residual and operational stresses can be assessed and structural damage identified. Composite smart structures can be manufactured by integrating fiber optic sensors into existing composite materials processes such as layup, filament winding and three-dimensional weaving. In this work optical fiber was integrated into 3D woven composite parts at a commercial woven products manufacturing facility. The fiber was then used to monitor the structures during a VARTM manufacturing process, and subsequent static and dynamic testing. Low cost telecommunications-grade optical fiber acts as the sensor using a high resolution commercial Optical Frequency Domain Reflectometer (OFDR) system providing distributed strain measurement at spatial resolutions as low as 2mm. Strain measurements using the optical fiber sensors are correlated to resistive strain gauge measurements during static structural loading."

  • Smart card
  • There are two types of smart cards: contact and contactless. Both have an embedded microprocessor and memory. The smart card differs from the proximity card in that the microchip in the proximity card has only one function: to provide the reader with the card's identification number. The processor on the smart card has an embedded operating system and can handle multiple applications such as a cash card, a pre-paid membership card, or an access control card.
  • A contactless card does not have to touch the reader or even be taken out of a wallet or purse. Most access control systems only read serial numbers of contactless smart cards and do not utilize the available memory. Card memory may be used for storing biometric data (i.e. fingerprint template) of a user. In such case a biometric reader first reads the template on the card and then compares it to the finger (hand, eye, etc.) presented by the user. In this way biometric data of users does not have to be distributed and stored in the memory of controllers or readers, which simplifies the system and reduces memory requirements.

  • Something with no reproduction costs can have no exchange-value in a context of free exchange.
  • Further, unless it can be converted into exchange-value, how can the peer producers be able to acquire the material needs for their own subsistence?
  • For Social Production to have any effect on general material wealth it has to operate within the context of a total system of goods and services, where the physical means of production and the virtual means of production are both available in the commons for peer production.

  • All texts published in Situationist International may be freely reproduced, translated and edited, even without crediting the original source
  • The point of the above is clear, the Creative Commons, is to help "you" (the "Producer") to keep control of "your" work. The right of the "consumer" is not mentioned, neither is the division of "producer" and "consumer" disputed.
  • Creative "Commons" is thus really an Anti-Commons, serving to legitimise, rather than deny, Producer-control and serving to enforce, rather than do away with, the distinction between producer and consumer
  • specifically providing a framework then, for "producers" to deny "consumers" the right to either create use-value or material exchange-value of the "common" stock of value in the Creative "Commons" in their own cultural production
  • Thus, the very problem presented by Lawrence Lessig, the problem of Producer-control, is not in anyway solved by the presented solution, the Creative Commons, so long as the producer has the exclusive right to chose the level of freedom to grant the consumer, a right which Lessig has always maintained support for
  • The Free Software foundation, publishers of the GPL, take a very different approach in their definition of "free," insisting on the "four freedoms:" The Freedom to use, the freedom to study, the freedom to share, and the freedom to modify.
  • The website of the creative commons makes the following statement about it's purpose: "Creative Commons defines the spectrum of possibilities between full copyright -- all rights reserved -- and the public domain -- no rights reserved. Our licenses help you keep your copyright while inviting certain uses of your work -- a 'some rights reserved' copyright
  • In all these cases what is evident is that the freedom being insisted upon is the freedom of the consumer to use and produce, not the "freedom" of the producer to control.
  • Moreover, proponents of free cultural must be firm in denying the right of Producer-control and denying the enforcement of distinction between producer and consumer
  • where a class-less community of workers ("peers") produce collaboratively within a property-less ("commons-based") society
  • Clearly, even Marx would agree that the ideal of Communism was commons-based peer production
  • the property in the commons is entirely non-rivalrous property
  • The use-value of this information commons is fantastic
  • However, if commons-based peer-production is limited exclusively to a commons made of digital property with virtual no reproduction costs then how can the use-value produced be translated into exchange-value?
  • Further, unless it can be converted into exchange-value, how can the peer producers be able to acquire the material needs for their own subsistence
  • The root of the problem of poverty does not lay in a lack of culture or information
  • but of direct exploitation of the producing class by the property owning classes
  • The source of poverty is not reproduction costs, but rather extracted economic rents, forcing the producers to accept less than the full product of their labour as their wage by denying them independent access to the means of production
  • So long as commons-based peer-production is applied narrowly to only an information commons, while the capitalist mode of production still dominates the production of material wealth, owners of material property, namely land and capital, will continue to capture the marginal wealth created as a result of the productivity of the information commons.
  • Whatever exchange value is derived from the information commons will always be captured by owners of real property, which lays outside the commons.
  • For Social Production to have any effect on general material wealth it has to operate within the context of a total system of goods and services, where the physical means of production and the virtual means of production are both available in the commons for peer production
  • For free cultural to create a valuable common stock it must destroy the privilege of the producer to control the common stock, and for this common stock to increase the real material wealth of peer producers, the commons must include real property, not just information
  • Kurt Laitner on 31 Jan 14
     
    Strong grasp of the issues, not entirely in agreement on the thesis that the solution is the removal of producer control as this does not support the initiation of an economy, only its ongoing function once established, and the economy is continuously intiating itself, so it is not a one time problem. I do support the notion that producers are in fact none other than consumers of prior art but also that effort is required to remix as much as the magical creation out of nothing. In order to incent this behavior then (or even merely to allow it) the basic scarce needs of the individual must be taken care of. This may be done by ensuring beneficial ownership, but even that suffers from the initiation problem, which the requires us to have a pool of wealth to kickstart the thing by supporting every last person on earth with a basic income - that wealth is in fact available...
