Note this resolver uses the `EcdsaSecp256k1RecoveryMethod2020` type and an `blockchainAccountId` to represent the default
`verificationMethod`, `assertionMethod`, and `authentication` entry.
Any value from the registry that returns an ethereum address will be added to the `verificationMethod` array of the DID
document with type `EcdsaSecp256k1RecoveryMethod2020` and an `blockchainAccountId` attribute containing the address.
