Classes

AddressExtension

This extension class enables some convenient methods (sugar for the most part) to deal with Address.

ByteUtil

Utility methods to deal with arrays.

Hashcash

This contains a set of functions that implements Hashcash, a proof-of-work system.

HashDigestExtension

Augments types to have some shortcut methods dealing with HashDigest<T> values.

Structs

Address

An identifier of 20 bytes (or 40 letters in hexadecimal, commonly with a prefix 0x) that refers to a unique account.

It is derived from the corresponding PublicKey of an account, but as a derivation loses information, it is always unidirectional.

The address derivation from a public key is as follows:

1. Calculates the Keccak-256, which is a previous form of SHA-3 before NIST standardized it and does not follow FIPS-202, of the corresponding PublicKey.
2. Takes only the last 20 bytes of the calculated Keccak-256 hash.
3. When the address needs to be shown to end users, displays these 20 bytes in hexadecimal, with a prefix 0x.

Since the scheme of the address derivation and the PrivateKey/PublicKey is the same to Ethereum, Ethereum addresses can be used by Libplanet-backed games/apps too.

HashDigest<T>

A value type to represent digest bytes determined by a . For more type safety, it takes a type parameter T of .

Nonce

An arbitrary s that determines a Hashcash.Stamp.

Delegates

Hashcash.Stamp

A delegate to determine a consistent s representation derived from a given nonce.

Since it is called multiple times with different nonces for proof-of-work system, the total time an implementation elapses should not vary for different nonces.
