Function blake3_compute_script_with_limb

bitvm/src/hash/blake3.rs:349–359

Returns a script that computes the BLAKE3 hash of the message on the stack. The script processes compact message blocks and only unpacks them when needed, resulting in higher stack efficiency and support for larger messages. ## Parameters - `msg_len`: Length of the message. (excluding the padding, number of bytes) - `limb_len`: Limb length (number of bits per element) that the input in the stac

/// - Final result is left on the main stack as a BLAKE3 hash value. (in nibbles)
