Answer(Hashcash.Stamp, HashAlgorithmType, Int64, Int32, 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, int seed, CancellationToken cancellationToken = null)
Parameters
Type Name Description
Hashcash.Stamp stamp

A callback to get a “stamp” which is a 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.
Int32 seed

The seed number for random generator.
CancellationToken cancellationToken

A cancellation token used to propagate notification that this operation should be canceled.
Returns
Type Description
(, )<Nonce, ImmutableArray<Byte>>

A pair of Nonce value which satisfies the given difficulty, and the succeeded hash digest.
