Syntax

public static class Hashcash

Methods

Answer(Hashcash.Stamp, HashAlgorithmType, Int64, CancellationToken)

Finds a Nonce that satisfies the given difficulty. This process is so-called “mining”.

Declaration

public static (Nonce Nonce, ImmutableArray<byte> Digest) Answer(Hashcash.Stamp stamp, HashAlgorithmType hashAlgorithmType, long difficulty, CancellationToken cancellationToken = default(CancellationToken))

Parameters

Type	Name	Description
Hashcash.Stamp	stamp	A callback to get a “stamp” which is a Byte array determined from a given Nonce value.
HashAlgorithmType	hashAlgorithmType	The hash algorithm to use.
Int64	difficulty	A number to calculate the target number for which the returned answer should be less than.
CancellationToken	cancellationToken	A cancellation token used to propagate notification that this operation should be canceled.

Returns

Type	Description
(T1, T2)<Nonce, ImmutableArray<Byte>>	A pair of Nonce value which satisfies the given difficulty, and the succeeded hash digest.

Exceptions

Type	Condition
OperationCanceledException	Thrown when the specified cancellationToken received a cancellation request.
