Port ProofService binding record to blockchain

[nykma]

Description

ProofService is a zero-trust identity binding protocol.

All binding record is signed by user’s asymmetric keypair (called Avatar, currently secp256k1).

So there is a possibility to put ProofRecord’s existed binding record onto secp256k1-related blockchain, so that “smart contract”-ish on-chain program can use these data.

Expected outcomes

• Build a smart contract on EVM-based chain which holds all the binding records. It should at least:
  • Accept new record uploading (and verifying the signature before saving)
  • Has a public function to let other contract query these saved binding records.
• Modify proof_server to upload every new record onto this contract.

Skills required

• EVM programming (especially solidity)
• Basic knowledge of golang
