Verifier

A verifier is a cryptographic verification mechanism for an identity in FireFly.

FireFly generally defers verification of these keys to the lower layers of technologies in the stack - the blockchain (Fabric, Ethereum etc.) or Data Exchange technology.

As such the details of the public key cryptography scheme are not represented in the FireFly verifiers. Only the string identifier of the verifier that is appropriate to the technology.

Ethereum blockchains: The Ethereum address hex string
Hyperledger Fabric: The fully qualified MSP Identifier string
Data exchange: The data exchange "Peer ID", as determined by the DX plugin

Example¶

{
    "hash": "6818c41093590b862b781082d4df5d4abda6d2a4b71d737779edf6d2375d810b",
    "identity": "114f5857-9983-46fb-b1fc-8c8f0a20846c",
    "type": "ethereum_address",
    "value": "0x30017fd084715e41aa6536ab777a8f3a2b11a5a1",
    "created": "2022-05-16T01:23:15Z"
}

Field Descriptions¶

Field Name	Description	Type
`hash`	Hash used as a globally consistent identifier for this namespace + type + value combination on every node in the network	`Bytes32`
`identity`	The UUID of the parent identity that has claimed this verifier	`UUID`
`namespace`	The namespace of the verifier	`string`
`type`	The type of the verifier	`FFEnum`: `"ethereum_address"` `"tezos_address"` `"fabric_msp_id"` `"dx_peer_id"`
`value`	The verifier string, such as an Ethereum address, or Fabric MSP identifier	`string`
`created`	The time this verifier was created on this node	`FFTime`
