  • BitCoin, the first real implementation of BlockChain technology is in many ways not at all revolutionary.

    2

    What bitcoin does is nothing special. How bitcoin works is revolutionary.

  • BitCoin is the re-invention of the most basic workload in the world of modern computing: transaction processing.

    3

    The Block Chain

    CICS in 1966

  • The Blockchain is the generic name for the database and transaction processing capabilities that power BitCoin

    4

    One individual transaction record.

    The Hash is an encryption algorithm that provides a unique result for each block. Tampering with any record in the block will cause the hash to change and show attempted fraud.

    A group of transactions that are all approved at once and added to the database are called a Block.

    5

    String multiple blocks together and you get a BlockChain.

  • Though the results look similar to other systems, the way that BitCoin works is profoundly different

    6

    Distributed processing

    Every node in the network checks the work of other notes.

    Confirming transactions involves solving a small math problem with random numbers. Multiple parties work on this simultaneously.

    Transactions are confirmed by a kind of digital majority vote.

    The result is that collusion to approve fraudulent transactions is difficult.

    Synchronized RecordsEvery participant in the network keeps a copy of all the transactions.

    Transactions are secured by encryption to prevent tampering.

    Change your transaction history, and your hash numbers will be out of sync with all others, exposing tampering.

  • BitCoin may the single most secure piece of commercial information technology ever created

  • You can use BitCoin and its core technology in number of different ways.

  • You can also use the public BitCoin BlockChain as a kind of digital records & operations platform

    11

    BitCoin As A PlatformYou can insert information and records into transactions and do so in very tiny amounts - $0.00001 cents, for example.

    You can take advantage of the public nature of the blockchain and the large number of people securing it with their computing power.

  • You can also take the technology and build your own entirely new platform and fresh blockchain

    12

    As A Bank & Currency

    BitCoin As A Platform

    Blockchain PlatformsYou can replace the currency component with any transactional data you want and build your own programming & transaction platform.

    It can be public, private or a hybrid.

  • The future is already here, its just not evenly distributed.

  • The computing power required to run Blockchain-based applications is now spreading far and wide

    14

    Powerful System on Chip costs are dropping so quickly, they are converging with traditional embedded chip costs:

    Non-Recurring Engineering Cost for Customized Embedded Chips

    Shift to SOC with software customization here

    Illustrative: As SOCs drop in price, customization will shift to software, not hardware

    Embedded Unit CostAverage Embedded CostAverage SOC Cost

    At higher end of the market, this shift has already started:

    These high powered SOC chips can run the full technology stack - they are servers in their own right, no need for a data center any more.

    Apple Lightning HDMI Adapter

    Full ARM SoC with over 256MB of RAM

    Boots OS X Core when plugged in

    Conducts software conversion of MPEG to HDMI in real time

  • The computing power in every-day things is already more than everything in every data center.
