}

The hashing algorithm used for generating storage keys.

Variants

Blake2_128

Blake2 128-bit hash.

Blake2_256

Blake2 256-bit hash.

Blake2_128Concat

Blake2 128-bit hash followed by the input data.

Twox128

XX 128-bit hash.

Twox256

XX 256-bit hash.

Twox64Concat

XX 64-bit hash followed by the input data.

Identity

Identity hashing (no hashing, data used as-is).
