DIDDoc stores the DID Document

Used in: IdentityDID

• repeated string context = 1

• required string id = 2

• repeated PublicKey publickey = 3

• repeated DIDService service = 4

• repeated VerificationMethod authentication = 5

DIDService is a description of a service endpoint.

Used in: DIDDoc

• required string id = 1

• required string type = 2

• required sint32 priority = 3

• repeated string recipientkeys = 4

• repeated string routingkeys = 5

• required string serviceendpoint = 6

Darc is the basic structure representing an access control. A Darc can evolve in the way that a new Darc points to the previous one and is signed by the owner(s) of the previous Darc.

Used in: byzcoin.CreateGenesisBlock

• required uint64 version = 1

  Version should be monotonically increasing over the evolution of a Darc.

• required bytes description = 2

  Description is a free-form field that can hold any data as required by the user. Darc itself will never depend on any of the data in here.

• optional bytes baseid = 3

  BaseID is the ID of the first darc in the chain of evolution. It is not set if the darc is on version 0.

• required bytes previd = 4

  PrevID is the previous darc ID in the chain of evolution.

• required Rules rules = 5

  Rules map an action to an expression.

• repeated Signature signatures = 6

  Signature is calculated on the Request-representation of the darc. It needs to be created by identities that have the "_evolve" action from the previous valid Darc.

• repeated Darc verificationdarcs = 7

  VerificationDarcs are a list of darcs that the verifier needs to verify this darc. It is not needed in online verification where the verifier stores all darcs.

Identity is a generic structure can be either an Ed25519 public key, a Darc or a X509 Identity.

Used in: byzcoin.CheckAuthorization, byzcoin.Instruction, Request, Signature, personhood_service.PartyDelete, personhood_service.PollDelete

• optional IdentityDarc darc = 1

  Darc identity

• optional IdentityEd25519 ed25519 = 2

  Public-key identity

• optional IdentityX509EC x509ec = 3

• optional IdentityEvmContract evmcontract = 5

  Address of an EVM contract

• optional IdentityDID did = 6

  A claim signed by one of the keys in a DID Doc

• optional IdentityTSM tsm = 7

  Public-key identity from an ECDSA key

IdentityDID holds the DID and DIDDoc required to verify a claim from a decentralized identifier

Used in: Identity
