Defrag x blockchain keynote

  1. 1. Introducing Hyperledger Blockchain technologies for business Duncan Johnston-Watt, CEO, Cloudsoft Defrag X, November 2016 @duncanjw
  2. 2. 21st Century Alchemy @duncanjw Open Source A seemingly magical process of transformation, creation, or combination …
  3. 3. About The Linux Foundation The Linux Foundation is the organization of choice for the world's top developers and companies to build ecosystems that accelerate open technology development and commercial adoption. Together with the worldwide open source community, it is solving the hardest technology problems by creating the largest shared technology investment in history. Founded in 2000, The Linux Foundation today provides tools, training and events to scale any open source project, which together deliver an economic impact not achievable by any one company. The Linux Foundation has 16 years experience of providing governance structure and infrastructure to support the development of large scale, successful open source projects such as: @hyperledger
  4. 4. Project Goals Build an Open Source developer-focused community of communities to benefit an ecosystem of Hyperledger-based solution providers and users, focused on blockchain-related use cases that will work across a variety of industry sectors. Through this, create a family of enterprise grade, open source blockchain frameworks, platforms, and libraries, upon which anyone can build and run their own applications to meet real business needs. Involve developers, service providers, solution providers and end users in the development and promotion of the software, using the best practices of a multi-stakeholder Open Source community. Host the collaboration environment for the community, establishing a neutral home for community infrastructure, meetings, events and collaborative discussions and providing structure around the business and technical governance of Hyperledger. @hyperledger
  5. 5. Executive Director Brian Behlendorf Behlendorf was a primary developer of the Apache Web server, the most popular web server software on the Internet, and a founding member of the Apache Software Foundation. He has also served on the board of the Mozilla Foundation since 2003 and the Electronic Frontier Foundation since 2013. He was the founding CTO of CollabNet and CTO of the World Economic Forum. Most recently, Behlendorf was a managing director at Mithril Capital Management LLC, a global technology investment firm. @brianbehlendorf
  6. 6. Who Supports Hyperledger?
  7. 7. There will not be only one blockchain, or a chain-of-all-chains. There will be many public chains and millions of private chains, potentially each with a different consensus mechanism, preferred smart contract language/mechanism, and other characteristics. The more common code underlying these chains, the better for everyone. This is still early days – perhaps like 1994 and the Web? A World of Many Chains @hyperledger
  8. 8. The Problem with the Traditional Approach @hyperledger
  9. 9. How Blockchain Solves This @hyperledger
  10. 10. Status This project is in Incubation Description Fabric is an implementation of blockchain technology, leveraging familiar and proven technologies. It is a modular architecture allowing pluggable implementations of various functions. It features powerful container technology to host any mainstream language for smart contracts development. Key Characteristics Permissioned network, core written in Go, chaincode in Go or Java. https://wiki.hyperledger.org/projects/fabric.md Hyperledger Fabric @hyperledger

  14. 14. Membership Smart Contract Systems Management Events Consensus Network Wallet Shared Ledger contains the current world state of the ledger and a Blockchain of transaction invocations encapsulates business network transactions in code. transaction invocations result in gets and sets of ledger state a collection of network data and processing peers forming a Blockchain network. Responsible for maintaining a consistently replicated 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 responsible for integrating Blockchain bi-directionally with external systems. Not part of Blockchain, but used with it. Systems Integration Technical Terminology Source: Anthony O’Dowd,STSM IBM Blockchain Labs
  15. 15. Validating Node B Validating Node C Validating Node A Validating Node D Validating Node E Blockchain Network A chain network that services solutions built for a particular industry. Shared Ledger: Records all transactions across business network Consensus: Transaction validation & commitment Non- Validating Node Chaincode StateLogic Chaincode Chaincode Chaincode Proprietor(s) setup and define the purpose of a chain network. They are the stakeholders of a network. Auditors(s): Individuals or organizations with the permission to interrogate transactions and the blockchain network. Solution Users: end users typically initiatetransactions on a chain network through applications made available by solutions providers. Non-Validating node: Constructs transactions and forwards them to validating nodes. Peer nodes keep a copy of all transaction records so that solution providers can query them locally. Solution Provider: Organizations that develop mobile/web applications for solution users to access chain networks., they own either NV or Validating node. Public transactions: transactions with its payload in the clear Membership Service (PKI) ECA TCA TLS-CAReg. A Registration Authority: Assigns registration username & registration password pairs to network participants. This username/password pair will be used to acquire enrollment certificate from ECA. Enrollment CA (ECA): Issues enrollment certificates (ECert) to network participants that have already registered with a membership service. ECerts are long term certificates used to identify individual entities participating in one or more networks. Transaction CA (TCA): Issues transaction certificates (TCerts) to ECert owners. An infinite number of TCerts can be derived from each ECert. TCerts are used by network participants to send transactions. TLS CA: Issues TLS certificates to systems that transmit messages in a chain network. TLS certificates are used to secure the communication channel between systems. Chaincode (Smart Contract): Application logics stored and executed on the blockchain. Chaincode State: Chaincodes access internal state storage through state APIs. States are created and updated by transactions calling chaincode functions with state accessing logic. Confidential transactions: transactions where its payload is encrypted and is only visible to stakeholders of this transaction Confidential chaincode: chaincodes that only pre-defined subset of validators can view and execute The Blockchain Network Source: Sharon Weed @hyperledger

  18. 18. Hugely successful Sotheby’s auction Every lot exceeds its reserve price and is sold on the night The collection is split up and acquired by three art collectors Charlie, Dave and Edwina who are tech savvy and want to loan each other works Sotheby’s sets up a secure private asset management system Alice deploys chaincode and makes Bob the administrator Sotherby’s initializes asset management system Bob loads auction results – ensuring each lot is allocated to correct collector Demo – Scenario @itsMeMikeZ
  19. 19. Demo – Asset Management The asset management chaincode is a simple example designed to show how to exercise access control at the chaincode level as described in this document: https://github.com/hyperledger/fabric/blob/master/docs/tech/application-ACL.md The chaincode exposes the following functions: init(user): Initialize the chaincode assigning to user the role of administrator assign(asset, user): Assigns the ownership of asset to user. Notice that, this function can be invoked only by an administrator transfer(asset, user): Transfer the ownership of asset to user. Notice that this function can be invoked only by the owner of asset query(asset): Returns the identifier of the owner of asset https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management @itsMeMikeZ
