The blake2s_state consists of the following components: h: A 64-byte chain value denoted decomposed as (h_0, h_1, ..., h_7), each h_i is a 32-bit number. It form the first two rows on the internal state matrix v of the compression function G.

t: It is a counter (t_0 lsb and t_1 msb) used in the initialization of the internal state v.

f: f_0 and f_1 are finalization flags used in the initialization of the internal state v. / 0xfff...ff if the block processed is the last f_0 = | \ 0x000...00 otherwise / 0xfff...ff if the last node is processed in merkle-tree hashing f_1 = | \ 0x000...00 otherwise

Further, the internal state 4x4 matrix used by the compression function is denoted by v. The input data is stored in the 16-word message m.
