A hash function is any function that can be used to map data of arbitrary size to fixed-size values. The values returned by a hash function are called hash values, hash codes, digests, or simply hashes. Use of a hash function to index a hash table is called hashing or scatter storage addressing. Like all computer data, hashes are large numbers, and are usually written as hexadecimal.
Hash functions in JaxNet
Mining hash functions
Jax.Network uses SHA-256d as a mining hash function. The letter 'd' refers to the fact that cryptographic hash function SHA-256 is applied twice.
Linking hash functions
Linking hash function is used to link data records in JaxNet in order to make them immutable. By design, this cryptographic hash function should be efficient and very fast.
Jax.Network uses Blake-256 as a linking hash function.
