  26. 26. Business networks, wealth & markets 26 o Business Networks benefit from connectivity • Participants are customers, suppliers, banks, partners • Cross geography & regulatory boundary o Wealth is generated by the flow of goods & services across business network o Markets are central to this process: • Public (fruit market, car auction), or • Private (supply chain financing, bonds)) o The easier it is to conducttransactions, the more people transact
  27. 27. Many business transactions remain inefficient, expensive and vulnerable 27 Time Many business transactions: § are time sensitive § require much settlement and reconciliation time § are process-delay prone Cost Many business transactions: § include overheads from multiple intermediaries § are costly to manage and execute § require extensive documentation Risk Many business transactions: § are ambiguous and non-verifiable § are prone to errors and tampering § have no single source of truth Source: IBM Institute for Business Value analysis
  28. 28. Adoption patterns: we expect Blockchain to fundamentally change how we do business 28 A new science of organizations Codifications of contracts, compliance and certifications will redefine how trust is embodied in business transactions Efficient and accessible market-places built on blockchains will accelerate the exchange of value and flow of wealth The tightening of trust A new nexus for value exchange Highly efficient distributed business networks will challenge our notions of traditional enterprise management
  29. 29. Full transformation value kicks in when a variety of industries and activities come together 29 Limited value within the boundaries of a single organization Ecosystem participants have to agree on a standard

  43. 43. @benji_fuentes Introduction to Blockchain and Hyperledger Benjamin Fuentes IBM
  44. 44. @benji_fuentes Blockchain • Introduction • Hyperledger • Blockchain as a Service (on Bluemix Cloud)
  45. 45. @benji_fuentes Blockchain - Introduction A blockchain is a distributed database, introduced by Bitcoin (2008) on Satoshi Nakamoto’s white paper, that maintains a continuously- growing list of data records that each refer to previous items on this list and is thus hardened against tampering and revision Distributed systems answer to a problem called Byzantine Generals’ Problem described by Leslie Lamport (1982) As today, blockchains can be use to write distributed applications named “smart contract” or “chaincode” Mesopotamian ledger Byzantine Generals’ Problem
  46. 46. @benji_fuentes Blockchain - Hyperledger Hyperledger (or Hyperledger project) is a cross- industry collaborative effort to create blockchain-based open standard for distributed ledgers for globally conducted business transactions under the Linux Foundation The project aims to create an open-standard, public, decentralised public ledger based on blockchain technology to advance worldwide business transaction processing in terms of cost- effectiveness, speed and traceability More than 100 members Fabric Sawtooth Lake
  47. 47. @benji_fuentes Blockchain - Blockchain as a Service (on Bluemix Cloud) IBM is the only provider that gives you access to a permissioned Blockchain as a Service on its catalog of services
  48. 48. @benji_fuentes Fabric V0.6 • Actors • Components • Interactions • Architecture
  49. 49. @benji_fuentes Fabric - Actors The business user, operating in a business network. This role interacts with the Blockchain using an application. They are not aware of the Blockchain. The overall authority in a business network. Specifically, regulators may require broad access to the ledger’s contents. The developer of applications and smart contracts that interact with the Blockchain and are used by Blockchain users. Defines, creates, manages and monitors the Blockchain network. Each business in the network has a Blockchain Network operator. Manages the different types of certificates required to run a permissioned Blockchain. An existing computer systemwhich may be used by the Blockchain to augment processing. This system may also need to initiate requests into the Blockchain. An existing data system which may provide data to influence the behavior of smart contracts. Blockchain User Blockchain Developer Certificate Authority Blockchain Regulator Traditional Processing Platform Traditional Data Sources Blockchain Network Operator U R D O ü
  50. 50. @benji_fuentes Fabric - Components Membership Smart Contract Systems Management Events Consensus Network Wallet Ledger Contains the current World State of the ledger and a Blockchain of transaction invocations f(abc); Encapsulates business network transactions into logic code. Transaction invocations result in gets and sets of ledger state … E T A collection of network data and processing peers forming a Blockchain network. Responsible for maintaining a consistentlyreplicated ledger Manages identity and transaction certificates, as well as other aspects of permissioned access Creates notifications of significant operations on the Blockchain (e.g. a new block), as well as notifications related to smart contracts. Does not include event distribution. Provides the ability to create, change and monitor Blockchain components Securely manages a user’s security credentials i Responsible for integrating Blockchain bi-directionally with external systems. Not part of Blockchain, but used with it. Systems Integration
  51. 51. @benji_fuentes Fabric - Interactions Protocols : •SDK : use gRPC to communicate with a blockchain peer or Certificate Authority. Maintain the user’s key wallet •HTTP API : use HTTP (will be deprecated in V1.0) Functional interaction methods: •DEPLOY* : to deploy a chaincode •QUERY : to retrieve data from World State •INVOKE* : to call a chaincode method creating a transaction membership keys Consensus Ledger Events Chaincode state peer SDK ECA, TCA, TLS-CA API Blockchain network (* Creates a block on the chain)
  52. 52. @benji_fuentes Fabric - Architecture 1.Blockchain developer codes Application and Smart Contract 2.He deploys the app on a server and smart contract on a peer using DEPLOY 3.A registered user interacts with the app sending order (INVOKE) or retrieving information (QUERY) throught the smart contract 4.Smart contract can emit an event susbcribed by the app World/Ledger State Blockchain Genesis Block … Blockchain developer Smart Contra ct Invokes/queries on a smart contract Develops Application D SDK HTTP txn txn txn txn txn Block n PEER develops, then deploys emits PutState/GetState U Blockchain developer Interacts
  53. 53. @benji_fuentes Think distributed and deterministic !!! Get resources from external systems peer Blockchain network peer peer Ext system Put resources to external systems peer Blockchain network peer peer Ext system t1 t3 t2 1 call 1 call 1 call
  54. 54. @benji_fuentes Next coming on V1.0 (March 2017?) • Endorsement/consensus model • Plugging external identity server • Plugging external State DB • Historical queries • HTTP API deprecated, use SDK • Chaincode upgrades
  55. 55. @benji_fuentes Fabric V1.0 - Endorsement/Consensus model Peer role has been split : • Committer peer : commits transactions, maintainsledger and state • Endorsing peer: receives a transaction proposal for endorsement, responds granting or denying endorsement • Ordering peer: approves the inclusion of transaction blocks into the ledger and communicates with peer and endorsing peer nodes Also a peer can now communicate via private channels inside the network to strenghten privacy Different configuration options for the ordering service include: – SOLO • Single node for development – Kafka / Zookeeper • 1:n nodes providing Crash Fault Tolerance • Odd number of nodes recommended – SBFT (future) • 1:n nodes providing Byzantine Fault Tolerance Ordering-Service OO O O E C Peer types oror
  56. 56. @benji_fuentes Fabric V1.0 - Identity server New Identity server (COP) •make as pluggable as possible •make it decentralized •default implementation : CloudFlare's PKI/TLS toolkit •can be configured to read from an LDAP server •Developed in GO •CLI commands for server and client
  57. 57. @benji_fuentes Fabric V1.0 - External World State DB •Key/value database (LevelDB) •Document JSON database (CouchDB) •SQL data stores (future?) • requires schema definition • difficult to change schema CouchDB Chaincod e APIs LevelDB Worldstate
  58. 58. @benji_fuentes Fabric V1.0 - Historical queries Simple use case : • Show history of values for an asset X Rich queries : • Show value of an asset at a certain point in time • Show all assets having same field value through history (example : owned by a specific owner) tt-1t-2
  59. 59. @benji_fuentes Fabric V1.0 - HTTP deprecated, use SDK •Do not use HTTP API anymore •Use SDK over gRPC : •Java •NodeJs •Python
  60. 60. @benji_fuentes Fabric V1.0 - Chaincode upgrades • New command UPGRADE to use instead of redeploying another chaincode • Chaincode will contain version number … Smart Contra ct txn txn txn txn Smart Contra ct Application SDK HTTP UPGRADE Version N+1Version N World/Ledger State
