Get DID Identifier

The getDiDIdentifier function returns an identifier (identity's publicKey) from a privateKey.

getDidIdentifier returns a did Identifier using privateKey and profileNonce.

Future<String> getDidIdentifier({
  required String privateKey,
  required String blockchain,
  required String network,
  BigInt? profileNonce
});

privateKey of the identity is a key that is used to access the sensitive information of the identity. This key is also used for generating proofs by using the credentials associated with the identity.

blockchain is the name of the blockchain associated with the identity. In our case, it is Polygon.

network is the type of network (Mainnet or Testnet) associated with the identity.

profileNonce is the nonce of the profile of an identity.

note

It is worth noting that did is a Decentralized Identifier associated with an identity and enables verifiable identities. A did could be a person, thing, organization, or even an abstract entity. The controller of the did can prove that it is the real owner of the identity without the need of seeking permissions/approvals from any centralized authority.

A did is expressed in the following format (as per w3.org standards):

did: did method: did method-specific identifier
