  1. Building a Blockchain Platform Using Hyperledger Sawtooth and Seth Blockchain

    Technology Conference Andrew Donald Kennedy November 2018
  2. Introduction 2 @grkvlt

  3. Andrew Kennedy Distributed Systems Hacker Cloudsoft Corporation Engineer Open Source

    Contributor Apache Brooklyn Hyperledger Sawtooth Hyperledger Technical Ambassador @grkvlt
  4. Agenda Blockchain Hyperledger Sawtooth Ethereum Docker Compose Dockerfile Apache Brooklyn

    Results... 4 @grkvlt
  5. Blockchain Exciting, buzzword-compliant Alternative to databases! Details are a whole

    other talk... Lots of interest in Bitcoin and Ethereum Private blockchains as an alternative Any questions now? @grkvlt
  6. Blockchain allows multiple different parties to securely interact with the

    same universal source of truth Streamlined settlement, improved liquidity, increased transparency and new products/markets Finance Unite disparate processes, increase data flow and liquidity, reduce costs and improve patient experience and outcomes Healthcare Track parts and service provenance, ensure authenticity of goods, block counterfeits, reduce conflicts Supply Chain Shared Ledger Database @grkvlt
  7. Hyperledger Another part of the Linux Foundation Various Blockchain implementations

    Open source code from IBM and Intel Fabric, Sawtooth, Burrow @grkvlt
  8. 8 Together with the global technology community, The Linux Foundation®

    is solving the world’s hardest problems through open source and creating the largest shared technology investment in history. With 16 years experience providing governance structure, IT infrastructure and ecosystem development, The Linux Foundation is the umbrella organization for more than 50 open source projects accelerating open technology development and commercial adoption. Some of the game-changing initiatives hosted by The Linux Foundation include: Linux Foundation @grkvlt
  9. Where open source teams build diverse approaches for business blockchain

    technology systems Provide neutral, open, & community- driven infrastructures supported by technical and business governance Build technical communities to develop blockchain and shared ledger POCs, use cases, field trials and deployments Educate the public about the market opportunity for blockchain technology Promote our community of communities taking a toolkit approach with many platforms and frameworks Create enterprise grade, open source, distributed ledger frameworks & code bases to support business transactions Hyperledger Goals @grkvlt
  10. Hyperledger @grkvlt

  11. Sawtooth Originally Intel Blockchain Donated to Hyperledger as Sawtooth Pluggable

    consensus mechanism Various different transaction families @grkvlt
  12. Sawtooth @grkvlt

  13. Sawtooth @grkvlt

  14. Sawtooth Consensus Raft PoET PBFT @grkvlt

  15. Sawtooth PoET PoET consensus mechanism Proof of Elapsed Time Uses

    Skylake SGX secure enclave feature No burning the energy equivalent of a small country @grkvlt
  16. Ethereum Public and open EVM specification Reference implementation as Ethereum

    Solidity code for Smart Contracts Execute logic to determine if transaction is accepted Also ERC-20 standard for tokens/coins @grkvlt
  17. Sawtooth Seth Transaction Family Code for EVM from Burrow Seth

    implements Ethereum JSON-RPC @grkvlt
  18. Sawtooth Seth Smart Contract Code Written in Solidity Compiled to

    EVM Executed by calling RPC Endpoint Resulting blocks written to chain @grkvlt
  19. Sawtooth Deployment @grkvlt

  20. Sawtooth Deployment Plus @grkvlt

  21. Docker @grkvlt

  22. Docker Compose Simple prototyping on a single machine Compose YAML

    files supplied in Sawtooth repository Use these to build Docker images Deploy quickly to single machine for testing @grkvlt
  23. Docker Custom deployment with Docker Docker with networking Just add

    SDN driver and Data Store Kubernetes available soon…? @grkvlt
  24. Dockerfile Issues with Sawtooth Docker images Designed for development Need

    GitHub repository mounted as volume Huge images, multi Gigabyte Broken builds and repository code in flux Create new Dockerfiles for extra images needed @grkvlt
  25. Apache Brooklyn Cloud Orchestration Define and Manage Applications Scale and

    Shrink On Demand Policies for Actions Autonomic Computing Sensors and Effectors @grkvlt
  26. Apache Brooklyn Orchestrate Docker across multiple VMs Same functionality as

    Compose, almost Define containers and their relationships Inject various bits of configuration Easier than building a lot more custom Docker images Allows simple scaling, but see Swarm and services Eventually want to use more features like policies @grkvlt
  27. Apache Brooklyn @grkvlt

  28. Apache Brooklyn @grkvlt

  29. Results Work in Progress Deployment Demo CLI Access @grkvlt
