@nimiq/core / SignatureProof

Class: SignatureProof ​

Defined in: @nimiq/core/types/wasm/web.d.ts:1904

A signature proof represents a signature together with its public key and the public key's merkle path. It is used as the proof for transactions.

Properties ​

publicKey ​

readonly publicKey: PublicKey | ES256PublicKey

Defined in: @nimiq/core/types/wasm/web.d.ts:1954

The embedded public key.

signature ​

readonly signature: ES256Signature | Signature

Defined in: @nimiq/core/types/wasm/web.d.ts:1950

The embedded signature.

ES256_SINGLE_SIG_SIZE ​

readonly static ES256_SINGLE_SIG_SIZE: number

Defined in: @nimiq/core/types/wasm/web.d.ts:1946

SINGLE_SIG_SIZE ​

readonly static SINGLE_SIG_SIZE: number

Defined in: @nimiq/core/types/wasm/web.d.ts:1945

boolean

serialize() ​

serialize(): Uint8Array

Defined in: @nimiq/core/types/wasm/web.d.ts:1936

Serializes the proof to a byte array, e.g. for assigning it to a transaction.proof field.

Uint8Array

toPlain() ​

toPlain(): PlainTransactionProof

Defined in: @nimiq/core/types/wasm/web.d.ts:1940

Creates a JSON-compatible plain object representing the signature proof.

Returns ​

PlainTransactionProof

verify() ​

verify(data): boolean

Defined in: @nimiq/core/types/wasm/web.d.ts:1928

Verifies the signature proof against the provided data.

Parameters ​

multiSig() ​

static multiSig(signer_key, public_keys, signature): SignatureProof

Defined in: @nimiq/core/types/wasm/web.d.ts:1916

Creates a Ed25519/Schnorr signature proof for a multi-sig signature. The public keys can also include ES256 keys.
