5. Blockchain
   "Blockchain is a technology for a new generation of
   transactional applications that establishes trust, accountability
   and transparency while streamlining business processes."
   Or...
   "Blockchain is a distributed, cryptographically secure ledger of
   transactions."
   @grkvlt

6. Blockchain
   "A blockchain is a fully-distributed, peer-to-peer software
   network which makes use of cryptography to securely host
   applications, store data, and easily transfer digital instruments
   of value that represent real-world money. "

11. The Hyperledger Project is a
    collaborative effort created to
    advance Blockchain technology
    by identifying and addressing
    important features for a cross-
    industry open standard for
    Distributed Ledgers that can
    transform the way business
    Transactions are conducted
    globally.

17. Cloudsoft Blockchain Service
    • Deploy Hyperledger Frameworks to virtually any environment
    • Currently Hyperledger Fabric included in AMP
    • Hyperledger Burrow and Sawtooth in progress
    • Let developers focus on creating Chaincode or Smart Contracts, not the
    infrastructure and plumbing
    • Accelerate Time to Value for enterprises interested in Blockchain
    • Cloudsoft Blockchain Service is available via the IBM Marketplace
    • Cloudsoft is a Founder Member of the IBM Blockchain Ecosystem and
    a member of the Hyperledger Foundation

21. Hyperledger Application Fabric
    The Hyperledger Application Fabric is a group of Clusters of
    Docker Engines spread across different regions, giving a global
    deployment that can be easily scaled and extended.
    Hyperledger components are Docker containers providing
    Blockchain services.

22. Hyperledger and Kubernetes
    With the current popularity of Kubernetes as a container platform, it
    would be very useful to be able to deploy Hyperledger there.
    Kubernetes Pods are the unit of deployment for containers, and are
    defined as YAML resource files.
    The Cloudsoft AMP Container Service allows deployment of these
    Kubernetes resources, and we are in the process of developing Pods
    for the Hyperledger components. This feature will be part of the next
    release of the Cloudsoft HLF in AMP 5.0.

30. Simple Blueprint
    Extract the essential components from
    the previous architecture diagram:
    1. Web Application
    • Node.js Server and Redis Store
    2. Chaincode (or Smart Contract)
    • Reducing Complexity
    • Simple Brooklyn concepts
    • Dozen lines of YAML…

38. Hyperledger Sample Application
    We can demonstrate an asset management Chaincode
    application that spins up a Non-Validating Peer in a Docker
    container, deploys the Chaincode onto the Validating Peer
    Cluster and then performs the following Transactions:
    1. Assigns an asset to Alice
    2. Transfers to Bob and verifies ownership
    3. Transfers to Charlie and verifies ownership
    4. Transfers to Dave and verifies ownership
