  • 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
  • is the particular instant at which a structure exists or a process occurs
  • or the measured or measurable period over which a structure endures or a process continues.
  • durations

  • accelerations
  • irreversible unidirectionality of time
  • thermodynamics
  • negentropy
  • "time's arrow."
  • 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.
  • Conceptual system
  • Units
  • terms
  • Relationships
  • a set of pairs of units, each pair being ordered in a similar way
  • expressed by words
  • or by logical or mathematical symbols
  • operations
  • The conceptual systems of science
  • observer
  • selects
  • particular sets to study
  • Variable
  • Each member of such a set becomes a variable of the observer's conceptual system
  • conceptual system may be loose or precise, simple or elaborate
  • Indicator
  • an instrument or technique used to measure fluctuations of variables in concrete systems
  • Function
  • a correspondence between two variables, x and y, such that for each value of x there is a definite value of y, and no two y's have the same x, and this correspondence is: determined by some rule
  • Any function is a simple conceptual system
  • Parameter
  • An independent variable through functions of which other functions may be expressed
  • The state of a conceptual system
  • the set of values on some scale, numerical or otherwise, which its variables have at a given instant
  • Formal identity
  • variables
  • varies comparably to a variable in another system
  • If these comparable variations are so similar that they can be expressed by the same function, a formal identity exists between the two systems
  • Relationships between conceptual and other sorts of systems
  • Science advances as the formal identity or isomorphism increases between a theoretical conceptual system and objective findings about concrete or abstracted systems
  • A conceptual system may be purely logical or mathematical, or its terms and relationships may be intended to have some sort of formal identity or isomorphism with units and relationships empirically determinable by some operation carried out by an observer
  • Concrete system
  • a nonrandom accumulation of matter-energy, in a region in physical space-time, which is organized into interacting interrelated subsystems or components.
  • Units
  • are also concrete systems
  • Relationships
  • spatial
  • temporal
  • spatiotemporal
  • causal
  • Both units and relationships in concrete systems are empirically determinable by some operation carried out by an observer
  • patterns of relationships or processes
  • The observer of a concrete system
  • distinguishes a concrete system from unorganized entities in its environment by the following criteria
  • 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
  • Examples
  • number of its subsystems or components, its size, its rate of movement in space, its rate of growth, the number of bits of information it can process per second, or the intensity of a sound to which it responds
  • A variable is intrasystemic
  • not to be confused with intersystemic variations which may be observed among individual systems, types, or levels.
  • 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
  • special case
  • 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
  • the general case of concrete systems, of which living systems are a very special case. Nonliving systems need not have the same critical subsystems as living systems, though they often have some of them
  • Living system
  • a special subset of the set of all possible concrete systems
  • They all have the following characteristics:
  • open systems
  • inputs
  • throughputs
  • outputs
  • of various sorts of matter-energy and information.
  • maintain a steady state of negentropy even though entropic changes occur in them as they do everywhere else
  • by taking in inputs
  • higher in complexity or organization or negentropy
  • than their outputs
  • The difference permits them to restore their own energy and repair breakdowns in their own organized structure.
  • In living systems many substances are produced as well as broken down
  • To do this such systems must be open and have continual inputs of matter-energy and information
  • entropy will always increase in walled-off living systems
  • They have more than a certain minimum degree of complexity
  • They either contain genetic material composed of deoxyribonucleic acid (DNA)
  • or have a charter
  • blueprint
  • program
  • of their structure and process from the moment of their origin
  • may also include nonliving components.
  • They have a decider, the essential critical sub-system which controls the entire system, causing its subsystems and components to interact. Without such interaction under decider control there is no system.
  • other specific critical sub-systems or they have symbiotic or parasitic relationships with other living or nonliving systems
  • Their subsystems are integrated together to form actively self-regulating, developing, unitary systems with purposes and goals
  • They can exist only in a certain environment
  • change in their environment
  • produces stresses
  • Totipotential system
  • capable of carrying out all critical subsystem processes necessary for life is totipotential
  • Partipotential system
  • does not itself carry out all critical subsystem processes is partipotential
  • A partipotential system must interact with other systems that can carry out the processes which it does not, or it will not survive
  • parasitic
  • symbiotic

      The Exchange fime is a symbiotic system to SENSORICA
  • Fully functioning system
  • when it
  • Partially functioning system
  • it must do its own deciding, or it is not a system
  • Abstracted system
  • Units
  • relationships abstracted or selected by an observer in the light of his interests, theoretical viewpoint, or philosophical bias.
  • Some relationships may be empirically determinable by some operation carried out by the observer, but others are not, being only his concepts
  • Relationships
  • The relationships mentioned above are observed to inhere and interact in concrete, usually living, systems
  • these concrete systems are the relationships of abstracted systems.
  • The verbal usages of theoretical statements concerning abstracted systems are often the reverse of those concerning concrete systems
  • An abstracted system differs from an abstraction, which is a concept
  • representing a class of phenomena all of which are considered to have some similar "class characteristic." The members of such a class are not thought to interact or be interrelated, as are the relationships in an abstracted system
  • Abstracted systems are much more common in social science theory than in natural science.
  • are oriented toward relationships rather than toward the concrete systems
  • spatial arrangements are not usually emphasized
  • their physical limits often do not coincide spatially with the boundaries of any concrete system, although they may.
  • important difference between the physical and biological hierarchies, on the one hand, and social hierarchies, on the other
  • Most physical and biological hierarchies are described in spatial terms
  • we propose to identify social hierarchies not by observing who lives close to whom but by observing who interacts with whom
  • intensity of interaction
  • in most biological and physical systems relatively intense interaction implies relative spatial propinquity
  • To the extent that interactions are channeled through specialized communications and transportation systems, spatial propinquity becomes less determinative of structure.

      Tiberius Brastaviceanu on 25 Jun 11
       
      This is the case of SENSORICA, built on web-based communication and coordination tools. 
  • PARSONS
  • the unit of a partial social system is a role and not the individual.
  • culture
  • cumulative body of knowledge of the past, contained in memories and assumptions of people who express this knowledge in definite ways
  • The social system is the actual habitual network of communication between people.
  • RUESCH
  • A social system is a behavioral system
  • It is an organized set of behaviors of persons interacting with each other: a pattern of roles.
  • The roles are the units of a social system
    • Tiberius Brastaviceanu
      Tiberius Brastaviceanu on 25 Jun 11
       
      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

  • "Places to Intervene in a System," followed by nine items: 9.  Numbers (subsidies, taxes, standards). 8.  Material stocks and flows. 7.  Regulating negative feedback loops. 6.  Driving positive feedback loops. 5.  Information flows. 4.  The rules of the system (incentives, punishment, constraints). 3.  The power of self-organization. 2.  The goals of the system. 1.  The mindset or paradigm out of which the goals, rules, feedback structure arise.
  • an invitation to think more broadly about system change.
  • Numbers ("parameters" in systems jargon) determine how much of a discrepancy turns which faucet how fast.
  • some of which are physically locked in, but most of which are popular intervention points.
  • Probably ninety-five percent of our attention goes to numbers, but there's not a lot of power in them.
  • Not that parameters aren't important—they can be, especially in the short term and to the individual who's standing directly in the flow. But they rarely change behavior. If the system is chronically stagnant, parameter changes rarely kick-start it. If it's wildly variable, they don't usually stabilize it. If it's growing out of control, they don't brake it.
  • Spending more on police doesn't make crime go away.
  • Numbers become leverage points when they go into ranges that kick off one of the items higher on this list.
  • Probably the most common kind of critical number is the length of delay in a feedback loop.
  • A delay in a feedback process is critical relative to rates of change (growth, fluctuation, decay) in the system state that the feedback loop is trying to control.
  • Delays that are too short cause overreaction, oscillations amplified by the jumpiness of the response. Delays that are too long cause damped, sustained, or exploding oscillations, depending on how much too long. At the extreme they cause chaos. Delays in a system with a threshold, a danger point, a range past which irreversible damage can occur, cause overshoot and collapse.
  • delays are not often easily changeable
  • It's usually easier to slow down the change rate (positive feedback loops, higher on this list), so feedback delays won't cause so much trouble
  • Most systems have evolved or are designed to stay out of sensitive parameter ranges. Mostly, the numbers are not worth the sweat put into them.
  • The plumbing structure, the stocks and flows and their physical arrangement, can have an enormous effect on how a system operates.

    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

  • Scientific progress depends on both conceptual and technological advances, which in turn depend on the creativity of scientists

  • create optimal conditions in a research organization with the aim of enhancing the creativity of its scientific staff
  • Creativity has been traditionally associated with art and literature but since the early twentieth century, science has also been regarded as a creative activity
  • Measuring creativity is a challenging task owing to its complex and elusive nature
  • Measurement of brain activity showed that creativity correlates with two brain states: a quiescent, relaxed state corresponding to the inspiration stage, and a much more active state corresponding to the elaboration stage
  • models of creativity
  • have a common feature: they depend on a balance between analytical and synthetic thinking, and usually describe the creative process as a sequence of phases that alternate between these states
  • Most research on creativity has focused on the individual
  • However, more recent studies suggest that creativity also depends strongly on the social and cultural context
  • breakthroughs depended on collaboration and social support
  • social environment in business organizations affects the creativity of their employees
  • Although creative individuals are essential, the strong link with the environment indicates that creativity might be greatly enhanced by generating a culture that supports the creative process.
  • Many of the interviewees repeatedly emphasized three main qualities necessary to be a good scientist: rigorous intellect, the ability to get the job done and the ability to have creative ideas.
  • almost all interviewees characterized their breakthrough moment as an abrupt leap in understanding
  • Although breakthroughs in science depend on such an ‘internal' conceptual shift, they also rely on ‘external' experimental results. However, most interviewees described their breakthroughs as largely internal:
  • Only two scientists expressed the view that their breakthroughs were purely external events, based on the observation of novel data.
  • intuition
  • must be combined with rational thinking to be effective
  • Although the synthesis of a new concept relies on intuition, which is based on subconscious mental processing, it must be subjected to conscious examination and analysis
  • specific mental skills or attitudes
  • ability to make unexpected connections
  • ability to choose relevant possibilities from an infinite set of irrelevant ones
  • interest in the unknown'
  • enjoyment of the creative process
  • stimulation by interacting with colleagues
  • undoubtedly the most crucial trait for creativity, which thrives on the exchange of ideas
  • The majority felt that the individual and the collective are equally important:
  • what interactions are optimal for creativity
  • The majority of interviewees answered that other people provided them with ‘inspiration to do something new'
  • positive feedback after the emergence of a new idea is almost as important as the inspiration that triggered it
  • collective provides the individual with technical expertise
  • Therefore, scientists would value a culture of interaction and mutual inspiration more highly than access to technology, although the latter is essential for their experiments.
  • At the end of the interviews, each scientist was asked to describe the best possible conditions for generating creativity at a research institute.
  • Cross-fertilization is absolutely essential
  • These results indicate strongly that an interactive environment is the single most important factor for stimulating creativity
  • interacting with people doing very different things
  • interacting with colleagues informally
  • interactions within any institution are strongly affected by its organization
  • Several interviewees described ‘an open hierarchy' as an important factor for creativity
  • hierarchy is based on genuine respect because people are great scientists, but at the same time they're very approachable and open towards what you have to say
  • These results suggest that the best conditions for scientific creativity come with a free-flowing hierarchy and a highly developed culture of interaction to guarantee the exchange of ideas and inspiration.
  • Furthermore, interdisciplinary interactions lead to the generation of new and unusual ideas
  • Finally, because of the freedom to try new things, these ideas can be tested and eventually generate new insights.
  • Creativity can be described as an emergent phenomenon
  • nonlinear phenomena
  • Emergence depends on dynamic interactions between individual agents within the system
  • The importance of a ‘freedom to try new things' and a ‘free-flowing hierarchy' further supports the idea that individual components in an emergent system must be able to interact flexibly without central control
  • During the interviews, it became apparent that although a culture of interaction and creativity exists at EMBL, this itself is not often the subject of discussion. The values on which this culture is based are seemingly implicit rather than explicit
  • Potentially, the EMBL culture of interaction could be strengthened further by consciously expressing and discussing the values on which it is based

Mirroring Plastics - silver or "spray chrome" plastic and non-glass substrates - 0 views

shared by Francois Bergeron on 08 Sep 11 - No Cached
  • Plastic can be as glossy as glass but, unlike glass, it is hydrophobic – it repels water. If water does not flow smoothly over the surface, the mirroring chemicals will not deposit evenly. There are two ways to overcome this problem: You can flood the surface with so much water (or mirroring chemicals) that the beads merge into a smooth sheet. This technique works best using our mirror bath technique where the object to be mirrored is submerged in the chemicals. It is only practical for small objects. You can use a wetting agent (a type of surfactant) to break the surface tension on the plastic before you apply the mirroring chemicals. There are many types of plastic and each type has its own chemistry and surface characteristics. We have tested our Wetting Agent on some types of acrylic, polycarbonate and polyurethane. We have not tested it on all types of plastic. You should test it on a sample of your substrate to confirm that it works. See Cleaning and Polishing for more information on wetting agents.

  • resistance to neoliberalism
  • we are at a stage of emergence
  • difficulty of implementing full p2p solutions in the current dominant system
  • At this stage, there is a co-dependency between peer producers creating value, and for-profit firms ‘capturing that value’, but they both need each other.
  • Peer producers need a business ecology to insure the social reproduction of their system and financial sustainability of its participants, and capital needs the positive externalities of social cooperation which flow from p2p collaboration.
  • peer producing communities should create their own ‘mission-oriented’ social businesses, so that the surplus value remains with the value creators, i.e. the commoners themselves, but this is hardly happening now.
  • Instead what we see is a mutual accomodation between netarchical capital on one side, and peer production communities on the other.
  • the horizontal meets the vertical
  • mostly hybrid ‘diagonal’ adaptations
  • For peer producers the question becomes, if we cannot create our own fully autonomous institutions, how can we adapt while maintaining maximum autonomy and sustainability as a commons and as a community.
  • Why p2p have failed to create successful alternatives in some areas?
  • In commons-oriented peer production, where people aggegrate around a common object which requires deep cooperation, they usually have their own infrastructures of cooperation and a ecology combining community, a for-benefit association managing the infrastructure, and for-profit companies operating on the market place; in the sharing economy, where individuals merely share their own expressions, third party platforms are the norm. It is clear that for-profit companies have different priorities, and want to enclose value so that it can be sold on the marketplace. This in fact the class struggle of the p2p era, the struggle between communities and corporations around various issues because of partly differential interests.
  • Even commercially controlled platforms are being used for a massive horizontalisation and self-aggregation of human relationships, and communities, including political and radical groups are effectively using them to mobilize. What’s important is not just to focus on the limitations and intentions of the platform owners, but to use whatever we can to strengthen the autonomy of peer communities.
  • requires a clever adaptation
  • use for our own benefit
  • The fact today is that capital is still capable of marshaling vast financial and material resources, so that it can create,
  • platforms that can easily and quickly offer services, creating network effects
  • without network effects, there is no ‘there’ there, just an empty potential platform.
  • p2p activists should work on both fronts
  • using mainstream platforms for spreading their ideas and culture and reach greater numbers of people, while also developing their own autonomous media ecologies, that can operate independently, and the latter is an engagement for the ‘long haul’, i.e. the slow construction of an alternative lifeworld.
  • The commons and p2p are really just different aspects of the same phenomena; the commons is the object that p2p dynamics are building; and p2p takes place wherever there are commons.
  • So both p2p and the commons, as they create abundant (digital) or sufficient (material) value for the commoners, at the same time create opportunities to create added value for the marketplace. There is no domain that is excluded from p2p, no field that can say, “we wouldn’t be stronger by opening up to participation and community dynamics”. And there is no p2p community that can say, we are in the long term fully sustainable within the present system, without extra resources coming from the market sector.
  • One trend is the distribution of current infrastructures and practices, i.e. introducing crowdsourcing, crowdfunding, social lending, digital currencies, in order to achieve wider participation in current practices. That is a good thing, but not sufficient. All the things that I mention above, move to a distributed infrastructure, but do not change the fundamental logic of what they are doing.
  • we are talking about the distribution of capitalism, not about a deeper change in the logic of our economy.
  • No matter how good you are, no matter how much capital you have to hire the best people, you cannot compete with the innovative potential of open global communities.
  • the p2p dynamics
  • the new networked culture
  • the opposite is also happening, as we outlined above, more and more commons-oriented value communities are creating their own entrepreneurial coalitions. Of course, some type of companies, because of their monopoly positions and legacy systems, may have a very difficult time undergoing that adaptation, in which case new players will appear that can do it more effectively.
  • the corporate form is unable to deal with ecological and sustainability issues, because its very DNA, the legal obligation to enrich the shareholders, makes its strive to lower input costs,  and ignore externalities.
  • we need new corporate structures, a new type of market entity, for which profit is a means, but not an end, dedicated to a ‘benefit‘, a ‘mission’, or the sustenance of a particular community and/or commons.
  • abundance destroys scarcity and therefore markets
  • open design community
  • will inherently design for sustainability
  • for inclusion
  • conceive more distributed forms of manufacturing
  • entrepreneurs attaching themselves to open design projects start working from an entirely different space, even if they still use the classic corporate form. Prevent the sharing of sustainability designs through IP monopolies is also in my view unethical and allowing such patents should be a minimalist option, not a maximalist one.
  • The high road scenario proposes an enlightened government that ‘enables and empowers’ social production and value creation and allows a much smoother transition to p2p models; the low road scenario is one in which no structural reforms take place, the global situation descends into various forms of chaos, and p2p becomes a survival and resilience tactic in extremely difficult social, political and economic circumstances.
  • accelerated end of capitalism
  • Making sure that we get a better alternative is actually the historical task of the p2p movement. In other words, it depends on us!
  • I don’t really think in terms of technological breakthroughs, because the essential one, globally networked collective intelligence enabled by the internetworks, is already behind us; that is the major change, all other technological breakthroughs will be informed by this new social reality of the horizontalisation of our civilisation. The important thing now is to defend and extend our communication and organisation rights, against a concerted attempt to turn back the clock. While the latter is really an impossibility, this does not mean that the attempts by governments and large corporations cannot create great harm and difficulties. We need p2p technology to enable the global solution finding and implementation of the systemic crises we are facing.

  • Where nature can take some work off our hands we should let it.
  • a shift towards renewable resources
  • 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.
  • The concept of waste is essentially a reflection of poor design. Every output from one system could become the input to another system. We need to think cyclically rather than in linear systems.

  • ask how is what we are doing part of a bigger picture, the move away from globalisation and towards the local, taking steps back from the everyday.
  • This can be done firstly by allowing space for Devil’s advocates, for black sheep, for hearing the voices of those outside of the dominant culture of the organisation and secondly by looking from a holistic perspective of how things interconnect, rather than just relying on experts who are embedded in detail. It emphasises the need to value the generalist, to give value to holistic thinkers.
  • allowing people to imagine different possibilities.
  • scenario planning
  • Permaculture has been described as the science of maximising beneficial relationships.
  • Solutions are to be found in integrated holistic solutions rather than increased specialisation and compartmentalisation
  • The challenge here is to move to seeing business as being part of the geographical community, as being rooted in place, rather than just part of a globalised community. 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
  • the notion that big is best needs to be challenged
  • new opportunities are very hard to understand and exploit from a macro level perspective, and are much better done from small scale perspective. It is here that the idea of appropriateness of scale becomes key.

  • not having all your eggs in one basket.
  • In the short term this kind of diversification could reduce profits, but in the longer term it will be more secure
  • this is about the reverse of specialisation, about having a mixed portfolio, and presents a big culture change for businesses.
  • 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
  • ‘edge’
  • the point where two ecosystems meet is often more productive than either of those systems on their own.
  • 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.

  • giving rewards to customers can actually undermine a company’s relationship with them
  • It just is not so easy to assume that because people behave productively in one framework (the social process of peer production that is Wikipedia, free and open source software, or Digg), that you can take the same exact behavior, with the same exact set of people, and harness them to your goals by attaching a price to what previously they were doing in a social process.

  • It’s what we would call a robust effect. It shows up in many contexts. And there’s been considerable testing to try to find out exactly why it works. A major school of thought is that there is an “Overjustification Effect.” (http://kozinets.net/archives/133)
    • Kurt Laitner
      Kurt Laitner on 17 Jul 15
       
      yes, why is key
  • interesting examples of an effect called crowding
  • Offering financial rewards for contributions to online communities basically means mixing external and intrinsic motivation.
  • A good example is children who are paid by their parents for mowing the family lawn. Once they expect to receive money for that task, they are only willing to do it again if they indeed receive monetary compensation. The induced unwillingness to do anything for free may also extend to other household chores.
  • Once ‘gold-stars’ were introduced as a symbolic reward for a certain amount of time spent practicing the instrument, the girl lost all interest in trying new, difficult pieces. Instead of aiming at improving her skills, her goal shifted towards spending time playing well-learned, easy pieces in order to receive the award (Deci with Flaste 1995)
    • Kurt Laitner
      Kurt Laitner on 17 Jul 15
       
      this is a more troubling example, as playing the harder pieces is also practicing - I would take this as a more complex mechanism at work - perhaps the reinterpretation by the girl that all playing was considered equal, due to the pricing mechanism, in which case the proximal solution would be to pay more for more complex pieces, or for levels of achievement - the question remains of why the extrinsic reward was introduced in the first place (unwillingness to practice as much as her parents wanted?) - which would indicate intrinsic motivation was insufficient in this case
  • Suddenly, she managed to follow the prescription, as her own (intrinsic) motivation was recognized and thereby reinforced.
    • Kurt Laitner
      Kurt Laitner on 17 Jul 15
       
      or perhaps the key was to help her fit the medication into her day, which she was having trouble with...
  • The introduction of a monetary fine transforms the relationship between parents and teachers from a non-monetary into a monetary one
    • Kurt Laitner
      Kurt Laitner on 17 Jul 15
       
      absolutely, in some sense the guilt of being late is replaced by a rationalization that you are paying them - it is still a rationalization, and parents in this case need to be reminded that staff have lives too to reinforce the moral suasion
  • "The effects of external interventions on intrinsic motivation have been attributed to two psychological processes: (a) Impaired self-determination. When individuals perceive an external intervention to reduce their self-determination, they substitute intrinsic motivation by extrinsic control. Following Rotter (1966), the locus of control shifts from the inside to the outside of the person affected. Individuals who are forced to behave in a specific way by outside intervention, feel overjustified if they maintained their intrinsic motivation. (b) Impaired self-esteem. When an intervention from outside carries the notion that the actor's motivation is not acknowledged, his or her intrinsic motivation is effectively rejected. The person affected feels that his or her involvement and competence is not appreciated which debases its value. An intrinsically motivated person is taken away the chance to display his or her own interest and involvement in an activity when someone else offers a reward, or commands, to undertake it. As a result of impaired self-esteem, individuals reduce effort.
    • Kurt Laitner
      Kurt Laitner on 17 Jul 15
       
      these are finally very useful - so from (a) as long as self determination is maintained (actively) extrinsic reward should not shut down intrinsic motivation AND (b) so long as motivations are recognized and reward dimensions OTHER THAN financial continue to operate, extrinsic reward should not affect intrinsic motivation
  • External interventions crowd-out intrinsic motivation if the individuals affected perceive them to be controlling
    • Kurt Laitner
      Kurt Laitner on 17 Jul 15
       
      emphasis on "if" and replacing that with "in so far as"
  • External interventions crowd-in intrinsic motivation if the individuals concerned perceive it as supportive
    • Kurt Laitner
      Kurt Laitner on 17 Jul 15
       
      interesting footnote
  • In that case, self-esteem is fostered, and individuals feel that they are given more freedom to act, thus enlarging self-determination
    • Kurt Laitner
      Kurt Laitner on 17 Jul 15
       
      so effectively a system needs to ensure it is acting on all dimensions of reward, or at least those most important to the particular participant, ego (pride, recognition, guilt reduction, feeling needed, being helpful, etc), money (sustenance, beyond which it is less potent), meaning/purpose etc.  If one ran experiments controlling for financial self sufficiency, then providing appreciation and recognition as well as the introduced financial reward, they might yield different results
  • cultural categories that oppose marketplace modes of behavior (or “market logics”) with the more family-like modes of behavior of caring and sharing that we observe in close-knit communities (”community logics”)

  • When communal logics are in effect, all sorts of norms of reciprocity, sacrifice, and gift-giving come into play: this is cool, this is right, this is fun
    • Kurt Laitner
      Kurt Laitner on 17 Jul 15
       
      true, and part of our challenge then is to remove this dichotomy
  • So think about paying a kid to clean up their room, paying parishioners to go to church, paying people in a neighborhood to attend a town hall meeting, paying people to come out and vote. All these examples seem a little strange or forced. Why? Because they mix and match the communal with the market-oriented.

      and perhaps the problem is simply the conversion to money, rather than simply tracking these activities themselves (went to church 50 times this year!, helped 50 orphans get families!) (the latter being more recognition than reward
  • Payment as disincentive. In his interesting book Freakonomics, economist Steven Levitt describes some counterintuitive facts about payment. One of the most interesting is that charging people who do the wrong thing often causes them to do it more, and paying people to do the right thing causes them to do it less.

      and we are left with the challenge, how to work to purpose but still have our scarce goods needs sufficiently provided for?  it has to be for love AND money
  • When people work for a noble purpose, they are told that their work is highly valued. When people work for $0.75/hour, they are told that their work is very low-valued

      this is a non argument, these are just interacting but separate problems, use ether or bitcoin, change legislation, what have you
  • Market economics. If you have open content, I can copy your content to another wiki, not pay people, and still make money. So by paying contributors, you're pricing yourself out of the market.

      exactly, so use commonsource, they can use it all they want, but they have to flow through benefit (provide attribution, recognition, and any financial reward must be split fairly)
  • You don't have to pay people to do what they want to do anyways. The labour cost for leisure activities is $0. And nobody is going to work on a wiki doing things they don't want to do.

      wow, exploitative in the extreme - no one can afford to do work for free, it cuts into paid work, family time etc.  if they are passionate about something they will do it for free if they cannot get permission to do it for sustenance, but they still need to sustain themselves, and they are making opportunity cost sacrifices, and if you are in turn making money off of this you are an asshole.. go ahead look in the mirror and say "I am an asshole"

      this is an utter cop out - figure out what is close enough to fair and iterate forward to improve it, wow
  • too complicated to do automatically. But if you have a subjective system -- have a human being evaluate contributions to an article and portion out payments -- it will be subject to constant challenges, endless debates, and a lot of community frustration.

      yes indeed, so get your metrics right, and be prepared to adjust them as they are gamed - and ultimately, as financial penalties are to BP, even if some people game the system, can we better the gaming of the capitalist system.. it's a low bar I know

  • 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.
