Methods

Answer(Hashcash.Stamp, Int64, CancellationToken)

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

Declaration

public static Nonce Answer(Hashcash.Stamp stamp, 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.
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
Nonce	A Nonce value which satisfies the given difficulty.

Declaration

public static HashDigest<SHA256> Hash(byte[] bytes)

Parameters

Type	Name	Description
Byte[]	bytes	A Byte array to calculate its hash digest.

Returns

Type	Description
HashDigest<SHA256>	A deterministic digest of the given bytes.
