Beyond Blockchain: Simple Scalable Cryptocurrencies - The World of Deep Wealth - Medium - 0 views

  • 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.

  • 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.

  • 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).

  • 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.

  • 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.

  • 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. When workers have no space for their own creative expression, when they are treated like automata not unique individuals, when they become demotivated and surly, when they treat their work as a necessary evil; this is no recipe for a functional organization.
  • 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.
  • voluntary slavery of ‘wagery’

  • 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
  • Formal interaction between colleagues takes place via “customer and supplier” relationships.
  • autonomy enables productivity
  • if one creates a space in which staff pursue their own goals and are not paid by the hour, they will focus on their activities not the clock; if they are not told what to do, they will need to develop their own initiative; if they are free to develop their own processes, they will discover through their own creative faculties how to work more productively- in pursuit of their goals
  • 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%.

  • 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.

Access control - Wikipedia, the free encyclopedia - 0 views

  • 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
  • a built in webservice to make it user friendly
  • 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

  • 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.

  • 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

      That is why we need a role system in SENSORICA
  • On the other hand, the society is an aggregate of social subsystems, and as a limiting case it is that social system which comprises all the roles of all the individuals who participate.
  • What Ruesch calls the social system is something concrete in space-time, observable and presumably measurable by techniques like those of natural science
  • To Parsons the system is abstracted from this, being the set of relationships which are the form of organization. To him the important units are classes of input-output relationships of subsystems rather than the subsystems themselves
  • system is a system of relationship in action, it is neither a physical organism nor an object of physical perception
  • evolution
  • differentiation
  • growth
  • from earlier and simpler forms and functions
  • capacities for specializations and gradients
  • [action] is not concerned with the internal structure of processes of the organism, but is concerned with the organism as a unit in a set of relationships and the other terms of that relationship, which he calls situation
  • 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

  • But a world of private ledgers sounds eerily similar to a range of “private Internets.”
  • Blockchain technology is useful not because it offers efficiency in a world of message-passing but because it uses a complex process to settle value between untrusted parties.
  • But distributed ledgers do not offer users the ability to easily convert their tokens and messages into fungible units of value. Nor do distributed ledgers escrow value between parties that don't trust each other.
  • If a ledger is not a public resource, it will have the pressures incumbent to existing settlement systems plus the overhead of maintaining a shared database among competitors. What efficiency will remain thereafter remains dubious.
  • Permissioned Blockchains

      This is also a problem with access, if an access event needs to be recorded in a way that cannot be altered, in a data location that cannot be altered, it will need to be stored on a block chain.

What is an ontology and why we need it - 1 views

  • an ontology designer makes these decisions based on the structural properties of a class.
  • an ontology is a formal explicit description of concepts in a domain of discourse (classes (sometimes called concepts)), properties of each concept describing various features and attributes of the concept (slots (sometimes called roles or properties)), and restrictions on slots (facets (sometimes called role restrictions)). An ontology together with a set of individual instances of classes constitutes a knowledge base. In reality, there is a fine line where the ontology ends and the knowledge base begins.
  • Classes describe concepts in the domain
  • ...16 more annotations...
  • A class can have subclasses that represent concepts that are more specific than the superclass.
  • Here we discuss general issues to consider and offer one possible process for developing an ontology. We describe an iterative approach to ontology development: we start with a rough first pass at the ontology. We then revise and refine the evolving ontology and fill in the details. Along the way, we discuss the modeling decisions that a designer needs to make, as well as the pros, cons, and implications of different solutions.
  • In practical terms, developing an ontology includes: �         defining classes in the ontology, �         arranging the classes in a taxonomic (subclass–superclass) hierarchy, �         defining slots and describing allowed values for these slots, �         filling in the values for slots for instances.
  • We can then create a knowledge base by defining individual instances of these classes filling in specific slot value information and additional slot restrictions.
  • Slots describe properties of classes and instances:
  • There is no one correct way to model a domain— there are always viable alternatives. The best solution almost always depends on the application that you have in mind and the extensions that you anticipate. 2)      Ontology development is necessarily an iterative process. 3)      Concepts in the ontology should be close to objects (physical or logical) and relationships in your domain of interest. These are most likely to be nouns (objects) or verbs (relationships) in sentences that describe your domain.
  • some fundamental rules in ontology design
  • how detailed or general the ontology is going to be
  • what we are going to use the ontology for
  • concepts in the ontology must reflect this reality
  • We suggest starting the development of an ontology by defining its domain and scope. That is, answer several basic questions: �         What is the domain that the ontology will cover? �         For what  we are going to use the ontology? �         For what types of questions the information in the ontology should provide answers? �         Who will use and maintain the ontology?
  • plan to use
  • domain
  • If the people who will maintain the ontology describe the domain in a language that is different from the language of the ontology users, we may need to provide the mapping between the languages.
  • One of the ways to determine the scope of the ontology is to sketch a list of questions that a knowledge base based on the ontology should be able to answer, competency questions
  • These competency questions are just a sketch and do not need to be exhaustive.

Food Safety in China, and the Risk to the U.S. - 0 views

  •  
    Three years after the melamine-in-milk scandal that made 300,000 children sick, and two years after China passed its first-ever food safety law in response, the country is still struggling to keep its food supply healthy. The Chinese government recently cracked down, closing almost 5,000 food-producing businesses and arresting 2,000 people -- but China experts say a needlessly complex bureaucracy and ferocious determination to turn a profit mean the contamination will keep coming. (On forums where expats chat, Westerners living in China wonder whether there is anything safe to eat.) (Update: Commenters at the China Law Blog, many of them apparently resident in China, reflect the same anxiety.)

  • You can connect triggers to one or more functions in a script. Any function can have multiple triggers attached. In addition, you can add trigger attributes to a function to further refine how the trigger behaves.
  • When a script runs because of a trigger, the script runs using the identity of the person who installed the trigger, not the identity of the user whose action triggered the event. This is for security reasons.
  • Installing an event handler may prompt for authorization to access
  • An event is passed to every event handler as the argument (e). You can add attributes to the (e) argument that further define how the trigger works or that capture information about how the script was triggered.

  • The emerging opportunities for businesses are things that are renewable. Renewable energy sources are the ones that will ensure a business’s stability in the long run. We can also broaden the concept of renewable resources to include things like goodwill and trust, things which a business can rebuild with good husbandry. Most business doesn’t just depend on law and competition, trust is at the heart of much business and it is very much a renewable resource.

At the moment for many larger businesses, the local is something one pays lip-service to as a source of good PR, something one is passing through, rather than actually being an integral part of the community.
  • This is a profound structural challenge for large organisations. Part of the resilience of the organisation comes from the degree of lateral integration. Resilience is in all solutions, it is the characteristic of ecological systems. If we apply these principles, resilience is one of the emergent properties

  • it is a good strategy for business to keep a diverse portfolio of what sustains the business, keep some things that appear to be peripheral. They may not at this stage appear to be a serious part of how the business is run, but in this new world they will increasingly become so

  • overlap systems where possible so as to maximise their potential.
  • recognising that innovation doesn’t come from the centre but from fringe thinkers.
  • giving status to the marginal
  • It is important that the business has as many fingers in as many pies as possible, as many interfaces, and recognises that every person working for the business represents it in the community.
  • Natural systems are constantly in flux, evolving and growing.
  • Remaining observant of the changes around you, and not fixing onto the idea that anything around you is fixed or permanent will help too.
  • be flexible, lean and adaptable
  • A healthy approach is to start with no complete plan, to allow the process to be emergent. This is not a time when we can work to a rigid plan as conditions will change so fast. Organisations will need to stay on their toes, without rigid management.

If not Global Captalism - then What? - 0 views

  • 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
       
      "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
       
      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

  • 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.

  • Proportional shares

  • 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.

  • 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.

      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.

  • a new class has arisen which controls the vectors of information
  • In terms of knowledge creation, a vast new information commons is being created, which is increasingly out of the control of cognitive capitalism.

  • But notice that to do this, the system had to change, the core logic was no longer the same.
  • The emergence of the peer model of production, based on the non-rivalrous nature and virtually non-existent marginal cost of reproduction of digital information, and coupled with the increasing unenforceability of “intellectual property” laws, means that capital is incapable of realizing returns on ownership in the cognitive realm.
  • capital is becoming an a posteriori intervention in the realization of innovation, rather than a condition for its occurrence
  • 1) The creation of non-monetary value is exponential 2) The monetization of such value is linear
  • What this announces is a crisis of value, most such value is ‘beyond measure’, but also essentially a crisis of accumulation of capital.
  • more and more positive externalizations are created from the social field
  • “the core logic of the emerging experience economy, operating as it does in the world of non-rival exchange, is unlikely to have capitalism as its core logic.”
  • This takes the form both of “intellectual property” law, as well as direct subsidies from the taxpayer to the corporate economy
  • crisis of realization under state capitalism to capital’s growing dependence on the state to capture value from social production and redistribute it to private corporate owners
  • The state capitalist system will reach a point at which, thanks to the collapse of the portion of value comprised of rents on artificial property, the base of taxable value is imploding at the very time big business most needs subsidies to stay afloat.
  • We live in a political economy that has it exactly backwards. We believe that our natural world is infinite, and therefore that we can have an economic system based on infinite growth. But since the material world is finite, it is based on pseudo-abundance. And then we believe that we should introduce artificial scarcities in the world of immaterial production, impeding the free flow of culture and social innovation, which is based on free cooperation, by creating the obstacle of permissions and intellectual property rents protected by the state. What we need instead is a political economy based on a true notion of scarcity in the material realm, and a realization of abundance in the immaterial realm.
  • Brains and bodies still need others to produce value, but the others they need are not necessarily provided by capital and its capacities to organize production.
  • The household and informal economies have been allowed to function to the extent that they bear reproduction costs that would otherwise have to be internalized in wages; but they have been suppressed (as in the Enclosures) when they threaten to increase in size and importance to the point of offering a basis for independence from wage labor. “
  • increasing untenability of property rights in the information realm
  • there is no more outside.
