- Aries Secure Storage initiatives:
- Mike working on documentation and architecture as an Aries RFC (KMS architecture) and Ursa RFC (API)
- PR is submitted: https://github.com/hyperledger/aries-rfcs/pull/440
- Mike and Cam's work aries-kms-mayaguez - Postgres backend for credential storage
https://github.com/sovrin-foundation/aries-kms-rs- Persistence work allows plugging in any database engine.
- Focus is using an external enclave.
- aries-kms-vostok - indy-wallet capabilities moved to an Aries base
- Andrew also working on that

- Ursa
- 0.4.0 scheduled for late March
- Improved hash to curve algorithm
- Updates to AMCL wrapper
- To replace libsodium, need to have a replacement for the anoncrypt / authcrypt sealed box for pack / unpack.
- Can be done in Ursa with two steps, but might add as a single function call.
- 0.4.0 scheduled for late March
Agenda:
Chained credentials (delegated credentials) - Aries RFC 0104: Chained Credentials
- Substantial update since the last version
- Chained credential solves the delegation problem but that is not the only one
- There is no specific requirements to change anything in the VC spec at all. is just about adopting convection
- VC are head for a problem - same problem as the certificate authorities at the beginning of the web, this what we are trying to avoid is to keep the list of all trusted parties. Instead of small list of entities to trust and cover whole space.
- If everyone can be issuers, the problem appears how to keep truck who I can trust.
- Data provenance → side the sources into VC
- We need clever way to do the revocation (wip)
- logic in verifier code is needed to support chained credentials
- how nonce is used in embedded proofs:
- verifier checks old nonce to verifiy that this happened in the past
- Does I have to disclose privacy by just letting someone walk up the history upstream of the credentials?:
- ZKP veriants and their privacy implications
- Cross correlation through multiple use - offline
- Anonymous of the entities in the chain can be achieved.
- Late and strong anonymity - is up to the case
Aries toolbox
- base Intention: "Postman" for Agent - to help developers to develop agents.
- Development tool
- Administrator tool - to control the agent
- Demo purposes
- UI module - corresponds to one or more protocols in the backend
- Discussion will be continued on the Call B .
