/timestamp/v3/jsonrpc

The JSON-RPC API provides methods assisting the construction of blockchain transactions for Timestamp operations, and interaction with the ledger.

Request

application/json

Bodyrequired

The body follows the JSON-RPC 2.0 specification.

It requires the following fields:

API Methods

insertHashAlgorithm

Call to build an unsigned transaction to insert a new hash algorithm.

Parameters:

• from: Ethereum address of the signer

timestampVersionHashes

Call to build an unsigned transaction to timestamp hashes and store them under the given record. It's possible to insert up to 3 hashes in a single transaction. This method can be called only by record owners.

Parameters:

• from: Ethereum address of the signer
• versionHash: Version hash to update
• hashAlgorithmIds: Array of hash algorithms ids used (up to 3)
• hashValues: Array of hashes (up to 3)
• timestampData (optional): Timestamp data. This field must be a JSON stringified and converted into hex string
• versionInfo: Version info. This field must be a JSON stringified and converted into hex string

insertRecordOwner

Call to build an unsigned transaction to insert a record owner. This method can be called only by record owners.

Parameters:

• from: Ethereum address of the signer
• recordId: Record ID to update
• ownerId: Ethereum address of new owner
• notBefore: Point in time when the owner becomes valid. It should be defined in epoch time.
• notAfter: Point in time when the owner becomes invalid. It should be defined in epoch time. For indefinite time set 0.

revokeRecordOwner

Call to build an unsigned transaction to revoke a record owner. This method can be called only by record owners.

Parameters:

• from: Ethereum address of the signer
• recordId: Record ID to update
• ownerId: Ethereum address of the owner to revoke

timestampRecordVersionHashes

Call to build an unsigned transaction to timestamp data and link it to a new version of an existing record. It's possible to insert up to 3 hashes in a single transaction. This method can be called only by record owners.

Parameters:

• from: Ethereum address of the signer
• recordId: Record ID to update
• hashAlgorithmIds: Array of hash algorithms ids used (up to 3)
• hashValues: Array of hashes (up to 3)
• timestampData (optional): Timestamp data. This field must be a JSON stringified and converted into hex string
• versionInfo: Version info. This field must be a JSON stringified and converted into hex string

appendRecordVersionHashes

Call to build an unsigned transaction to timestamp data and link it to an existing version of a record. It's possible to insert up to 3 hashes in a single transaction. This method can be called only by record owners.

Parameters:

• from: Ethereum address of the signer
• recordId: Record ID to update
• versionId: Version ID to update
• hashAlgorithmIds: Array of hash algorithms ids used (up to 3)

• timestampData (optional): Timestamp data. This field must be a JSON stringified and converted into hex string
• versionInfo: Version info. This field must be a JSON stringified and converted into hex string

detachRecordVersionHash

Call to build an unsigned transaction to detach a hash from the timestamps ids of a version of an existing record. This method can be called only by record owners.

Parameters:

• from: Ethereum address of the signer
• recordId: Record ID to update
• versionId: Version ID to update
• versionHash: Version hash to update
• hashValue: Hash value to detach

insertRecordVersionInfo
