Grano DID Contract

Grano DID Contract is cosmwasm based did (decentralized identifier) implementation inspired by ERC1056 DIDRegistry implementation.

WARNING: Grano DID Contract is under VERY ACTIVE DEVELOPMENT and should be treated as pre-alpha software. This means it is not meant to be run in production, its APIs are subject to change without warning and should not be relied upon, and it should not be used to hold any value.

grano-did-contract's Issues

【Refactor】Rename identity to identifier

Overview

I felt that "identity" was not appropriate because it encompasses a variety of information about the subject.
Since the DID's ID is only an identifier, I prefer to change the name to avoid unnecessary connotations.

[create] state for DID

Overview

Create state for DID.

  • owners (addr -> addr)
  • changed (addr-> uint)
  • nonce (addr -> uint)

📄 Add state for attributes

Overview

  • Add state for attributes
pub const ATTRIBUTES: Map<(&Addr, &String), Vec<String>> = Map::new("attribute");
pub const VALIDITIES: Map<(&Addr, &String, &String), Timestamp> = Map::new("validities");
  • Update ATTRIBUTES state when setAttribute and revokeAttribute is called.

Function

setAttribute

  • If the key is not exist, add the new key, and the value.
  • If the key is exist and the value is different, add the value.
  • If the key is exist and the value is the same, update the validity.

revokeAttribute

  • If the key is not exist, return error.
  • If the key exist and the value is different, return error.
  • If the key and value are exist, update the validity to 0.
