Know your Storage Provider (SP)

Issue claims to SPs that can be verified on-chain on the filecoin network

Parties Involved

Issuer (Trusted authority)

• Clients trust credentials issued by the Issuer
• Verifies info about SPs on filecoin network
• Issues claims to SPs e.g. Geolocation claim, Reliability score, Compliance claims (GDPR, HIPAA)
• Format of claims (claim schema) is published by Issuer on filecoin
• How to incentivize Issuer? - TBD

Holder (SP)

• SPs receive claims about them from Issuers
• SPs can prove facts about them, derived from info from claims, that can be verified on-chain by any actor
• This allows SP to prove any fact about themself to clients on-chain
• Example: SPs could sign up for a consortium of SPs that accept SPs with certain verified facts about them

Verifier (Clients)

• Clients looking for SPs can filter out potential SPs by requesting SPs to requesting proofs of facts about them
• A sample proof request could be:
  • I am looking for Storage Provider with
    • Compliance claim issued by Issuer X
    • Reliability score issued by Issuer Y
    • Geolocation claim issued by Issuer X

Flows

1. Identity creation for Issuer, SP, Verifier
2. Claim issuance to SP
3. Proof request on chain
4. On-chain proof verification

This project uses the concepts of iden3, zero knowledge proofs to generate claims and has a rest API layer to issue claims to the Storage Providers. The verification takes place using on chain verification done by smart contracts. The frontend is built using Next JS & Typescript along with Chakra UI.
