§Constructors

new AffixedProof({ hash, operations, network, timestamp }: AffixedProofOptions)

[src]

Throws InvalidTezosNetworkError if the Tezos network identifier is invalid.

@param hash

Input hash

@param operations

Proof operations

@param network

Tezos network identifier

@param timestamp

Asserted timestamp

§Properties

blockHash: string

[src]

Base58 encoded Tezos block hash

mainnet: boolean

[src]

Indicates that the proof is affixed to the Tezos mainnet

network: string

[src]

Tezos network identifier

timestamp: Date

[src]

Timestamp asserted by the proof

§Methods

concat(_: AnyProof): never

[src]

isAffixed(): this is AffixedProof

[src]

toJSON(): AffixedProofTemplate

[src]

verify(rpcURL: string): Promise<VerifyResult>

[src]

Verifies the proof by querying Tezos node RPC with the derived block hash and comparing the timestamp of the block header with the timestamp asserted by the proof.

Throws TypeError if the RPC URL is invalid or a network error is encountered.

Throws FetchError if the response has a status other than 200 or 404.

Throws SyntaxError if the fetched block header is not valid JSON or does not contain a valid timestamp field.

Resolves a VerifyResult containing a explanatory message of verification success or fail.

@param rpcURL

Tezos node RPC base URL
