Private 'Distributed Ledgers' Miss the Point of a Blockchain | Bank Think - 0 views

  • a new buzzword making waves throughout the financial industry: “distributed ledger.”
  • Some say it's a tool to enable transparency by ensuring that all members of a group receive cryptographically secured messages about participants’ activities
  • Some are even bold enough to predict that distributed ledgers will end the madness of managing multiple database and reconciliation structures.
  • ...13 more annotations...
  • Distributed ledgers have primarily claimed to supplant the need for Bitcoin's mining process by introducing trust requirements among participants. These ledgers also promise users the immutability of Bitcoin without the need for expensive mining operations.
  • the technology powering distributed ledgers predates blockchains by well over 20 years.
  • Proponents of distributed ledgers argue that they can displace centralized providers such as SWIFT,
  • by moving money faster
  • There’s no doubt that blockchain technology will facilitate disruptive innovations in finance
  • 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
  • their institutional users will probably find it expedient to hash their private-chain transactions and use those hashes to create bitcoin addresses and then send tiny fractions of a bitcoin to them to register their data at a location that cannot be hacked or changed.

      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. 
  • In other words, all private ledger/blockchains will lead to Bitcoin's Rome, driven there by its low cost and high public accountability.

Key management - Wikipedia, the free encyclopedia - 1 views

  • Key management
  • his includes dealing with the generation, exchange, storage, use, and replacement of keys.
  • Key management concerns keys at the user level, either between users or systems.
  • ...4 more annotations...
  • This is in contrast to key scheduling; key scheduling typically refers to the internal handling of key material within the operation of a cipher.
  • it involves system policy, user training, organizational and departmental interactions, and coordination between all of these elements.
  • Public Key Infrastructure (PKI)
  • A public key infrastructure is a type of key management system that uses hierarchical digital certificates to provide authentication, and public keys to provide encryption. PKIs are used in World Wide Web traffic, commonly in the form of SSL and TLS.

Card reader - Wikipedia, the free encyclopedia - 0 views

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

Robot's Gentle Touch Aids Delicate Cancer Surgery - 0 views

  • Surgeons have developed new minimally invasive surgery (MIS) techniques and instruments so that procedures that would previously have required a large incision can now be performed through a tiny 10mm cut.
  • University of Western Ontario and Canadian Surgical Technologies and Advanced Robotics (CSTAR) in London, Ontario
  • The researchers used a torque sensor to measure the force of the palpations.
  • ...2 more annotations...
  • Using tactile MIS sensing instruments under robotic control reduces the maximum force applied to the tissue by over 35% compared to a human controlling the same instrument. Accuracy in detecting the tumours was also far greater with the robot - between 59 and 90% depending on the robot control method used for palpation.
  • If developed further, the authors suggest that this type of instrument would particularly benefit surgeons performing lung tumour resection, where tissue often shifts significantly.

The commons law project: A vision of green governance - 0 views

  • “commons law” (not to be confused with common law)
  • Commons law consists of those social practices, cultural traditions and specific bodies of formal law that recognize the rights of commoners to manage their own resources
  • Ever since the rise of the nation-state and especially industrialized markets, however, commons law has been marginalized if not eclipsed by contemporary forms of market-based law
  • ...19 more annotations...
  • individual property rights and market exchange have been elevated over most everything else, and this has only eroded the rights of commoners,
  • reframe the very notion of “the economy” to incorporate non-market sharing and collaboration.
  • we had concluded that incremental efforts to expand human rights and environmental protection within the framework of the State/Market duopoly were simply not going to achieve much
  • the existing system of regulation and international treaties has been a horrendous failure over the past forty years. Neoliberal economics has corrupted and compromised law and regulation, slashing away at responsible stewardship of our shared inheritance while hastening a steady decline of the world’s ecosystems
  • We concluded that new forms of ecological governance that respect human rights, draw upon commons models and reframe our understanding of economic value, hold great promise
  • An economics and supporting civic polity that valorizes growth and material development as the precondition for virtually everything else is ultimately a dead end—literally.
  • Achieving a clean, healthy and ecologically balanced environment requires that we cultivate a practical governance paradigm based on, first, a logic of respect for nature, sufficiency, interdependence, shared responsibility and fairness among all human beings; and, second, an ethic of integrated global and local citizenship that insists upon transparency and accountability in all activities affecting the integrity of the environment.
  • We believe that commons- and rights-based ecological governance—green governance—can fulfill this logic and ethic. Properly done, it can move us beyond the neoliberal State and Market alliance—what we call the ‘State/Market’—which is chiefly responsible for the current, failed paradigm of ecological governance.
  • The basic problem is that the price system, seen as the ultimate governance mechanism of our polity, falls short in its ability to represent notions of value that are subtle, qualitative, long-term and complicated.
  • These are, however, precisely the attributes of natural systems.
  • Exchange value is the primary if not the exclusive concern.
  • anything that does not have a price and exists ‘outside’ the market is regarded (for the purposes of policy-making) as having subordinate or no value.
  • industry lobbies have captured if not corrupted the legislative process
  • regulation has become ever more insulated from citizen influence and accountability as scientific expertise and technical proceduralism have come to be more and more the exclusive determinants of who may credibly participate in the process
  • we have reached the limits of leadership and innovation within existing institutions and policy structures
  • it will not be an easy task to make the transition from State/Market ecological governance to commons- and rights-based ecological governance
  • It requires that we enlarge our understanding of ‘value’ in economic thought to account for nature and social well-being; that we expand our sense of human rights and how they can serve strategic as well as moral purposes; that we liberate ourselves from the limitations of State-centric models of legal process; and that we honor the power of non-market participation, local context and social diversity in structuring economic activity and addressing environmental problems.
  • articulate and foster a coherent new paradigm
  • deficiencies of centralized governments (corruption, lack of transparency, rigidity, a marginalized citizenry)
