    4. https://github.com/interNFT/nft-rfc/pulls
  2. Review of NFT Metadata Framework
    1. This structure let’s us talk about what is metadata and what is data in order to better approach the spec we are building
    2. We’ve created 2 workstreams

      1. Bearer Instruments
      2. Registered instrument
      3. Negotiable instrument
      4. https://www.investopedia.com/terms/b/bearer-instrument.asp
    2. Technical Approaches
      1. Bearer Tokens
      2. Constrained Tokens
        • Co-artifacts required for operationalization
        • Directed biometrically
        • Directed to “legally demonstrable” identity
        • Intersubjective Verification process could help here
    3. REQUIREMENT: must be able to specify rights & responsibilities
      1. Of the token as a token (property rights)
        • Ownership
        • Agency
        • Uniqueness
        • Divisibility
      2. Afforded an authorized presenter of the token (affordances)
        • Right to a specific seat in a particular venue for a particular show
        • Rights of access to information or location
        • Right to use a particular service (paywall)
    4. REQUIREMENT: Must be discoverable and understandable
      1. Must be verifiable as recognized by appropriate parties
      2. MAY be publicly committed, but privately described
      3. Warrantable completeness
    5. REQUIREMENT: Must be able to adjust and amend rights and responsibilities
      1. Changes to rights
      2. Constraints on changes to rights
      3. Attached or detached
    6. REQUIREMENT: must be able to operationalize rights
      1. Computational evaluation
      2. Through external actors/oracles
    7. REQUIREMENTS: Security
      1. Cryptographically provable ownershipi
      2. Cryptographically delegatable rights
      3. Non-repudiable transfers
      4. Atomic Transfers
      5. Auditability
      6. Key Management

    8. REQUIREMENTS: Privacy

      1. Off-chain, verifiable details
      2. Minimally pseudonymous property rights
        • We should be able to work with the level to which bitcoin provides pseudonymity
        • Add that we need to enable support for anonymous execution, for some definition of anonymous
      3. Self-contained namespace
      4. Self-contained authentication

    9. Representations - how do we record & communication rights?

      1. Code

    2. https://github.com/interNFT/nft-rfc/tree/main/spec/nft-rfc-003_native_NFT_interface
    3. https://github.com/interNFT/nft-rfc/tree/main/spec/nft-rfc-004_interNFT_standard
  3. Review - Rights
    1. https://github.com/interNFT/nft-rfc/pull/4
    2. Open conversation about defining and including bearer instruments
      1. Token rights and resource rights
  4. Next RFCs are not written yet:
    1. RFC006/Cap 19 (chain agnostic work) write up after next week’s call
    2. RFC007 Layer Model needs to be written up to explain in formal terms what we mean by metadata, how the layers in the system work together
  5. We want to wrap up this phase of work by the end of the year, and start the new year with draft standards
  6. Github issues and PRs review
    1. Move more of our conversation to github so we can distribute the conversation better for those who cannot make these calls. Please check out the urls and comment there.
    2. We have a lot of artifacts now, so the challenge is to get the engagement in conversation and to get people to try and give feedback so we can iterate and move forward.

    3. Verifiable Credentials
    4. Authorization Capabilities
    5. SES
    6. Resources
  11. Architecture Components
  12. These are components we are expecting to be supported on-chain (in Cosmos SDK)
    1. NFT Module
    2. IID Document Store
    3. IID Resolver
    4. DID Resolver
    5. Issuer Software
      1. In the VC world, and ZCaps there is a roll for Issuer Software and Verifier Software
      2. Needs to have access to the ability to sign with crypto keys and it creates a ZCap, or VC, or Verifiable Presentation
        1. Delegated non-centralized approach
        2. Often tied to a wallet, which is often off-line
        3. Web KMS
        4. Keystore
    6. Verifier Software
      1. Flip side of issuer software, if people developing for Cosmos blockchains to being able to verify a given ZCap or VC, they can call this component to do this verification
    7. Authorization Module
      1. https://github.com/cosmos/cosmos-sdk/blob/master/docs/architecture/adr-030-authz-module.md
      2. https://github.com/cosmos/cosmos-sdk/tree/master/x/authz
  13. Components in DID architecture (not in Cosmos SDK)
    1. Web KMS - part of Issuer Software
    2. Keystore - part of Issuer Software
    3. Confidential Storage
