32 bytes, derived using the Ed25519 algorithm.
64 bytes. The result of the Ed25519
sign: (privateKey, message) -> signature operation.
Serialized in 20 bytes usually created by keeping the first 20 bytes of a hash or a public key.
Alternatively, Nimiq addresses can also be expressed in a a human-friendly form:
NQCC XXXX XXXX XXXX XXXX XXXX XXXX XXXX XXXX
NQas a prefix for “Nimiq”.
- Followed by a two digit checksum (
CC) using the same algorithm like IBAN called MOD-97-10
- The remaining part (
XXXX ...) is the actual address base32 encoded as 32 characters. To reduce possibility of confusion the letters “I” and “O” are omitted.
A hash can be of three types, but only two are used: Blake2b and Argon2d - SHA256 can be used for contracts, Blake2b is the default. When creating a light hash, Blake2b is used while when creating a hard hash as a proof of work, Argon2d (memory-hard) is being used. Independently, a hash is always 32 bytes long.
The first byte (
type) is used to determind which size should be used. Very small numbers are stored straight in the first byte, bigger numbers are stored in 2 to 8 bytes.
|type||uint8||1||if < 0xFD, type is also the value|
|value||uint16..64||2..8||depends on type; 0xFD: uint16, 0xFE: uint32, otherwise unit64|
