Recap of ISO20022 presentation from SWIFT

  • PPT link : https://drive.google.com/file/d/0B7ecK_oVsnwOUTB5cEs1QVZrRlE/view?usp=sharing
  • current scopes of ISO20022 standard are
    • Business / Conceptual Layer defines financial concepts (Top Layer)
    • Logical Layer defines data and behaviour (processing) required to realize a business process
    • Physical layer that is a technical implementation derived from logical layer
  • opportunities with blockchain and ISO20022 are
    • re-use business / conceptual definications
    • define logical and physical layer
    • based on blockchain, data flow or behaviours are different from ISO20022 standard.
    • message format and/or storage is different when considering blockchain
  • Image DLT Logical Layer
    • Data and behaviour (processing) required to realize a business process;
    • The roles played by parties involved in a transaction: who can see what and who can do what;
    • Data definitions re-used from ISO 20022 business/conceptual
    • Behaviour derived from ISO 20022 business process definitions
    • Work will be required to adapt ISO 20022 to the new paradigm
  • Image DLT Physical Layer
    • ISO 20022 data structures represented physically on ledger
    • Data encapsulated according to Object Oriented principles
    • Behaviour implemented as Smart Contracts
    • Access rights enforced through Role Based Access Controls
    • Users authenticated by the platform
  • ISO20022.org is important
    • referencing with payment business ( http://www.iso20022.org/payments_messages.page )
    • Message Definication Report (http://www.iso20022.org/documents/general/Bank_Account_Management_Maintenance2013.zip) provide Business/Logical/Physical definication
      • Schema definication is at http://www.iso20022.org/documents/messages/acmt/schemas/acmt.007.001.02.zip (for example)
  • standardization approach by referencing ISO20022
    • choose use case
    • describe business / conceptual logic
    • define logical layer (data flow and behaviour) by considering blockchain
    • define message structure and storage
    • storage can be evaluated from various technologies

review UseCases

  • Use Case from Joe : https://docs.google.com/document/d/1JiGV7IUt1PTZg3JvBp9Cr0V7RyosOB_w-z6mMh87ktk/edit#
    • focusing more on Enterprise Systems use case
  • Use Case from Erik : https://github.com/w3c/blockchain/blob/master/use%20cases/blockchain_use_cases.md
    • will review more later

notes for blockchain standardization

  • note from Joe : https://docs.google.com/document/d/1xtfK1C7JbOLx-YztqEDloKBRXWwtFBaLm9pcSwLygAg/edit#heading=h.ie9haz2a79hp

more participants

  • consider moving concall time to 7am EST (current time is 6am EST / 10pm KST)
    • request comment on mailling list
  • two important milestones
    • blockchain workshop : https://www.w3.org/2016/04/blockchain-workshop/
    • W3C TPAC 2016 : https://www.w3.org/2016/09/TPAC/
  • keep continuing effort even with small active participants.
