Crate uhash_core 

uhash-core

Canonical M1 mining API in this crate is Lithium v1:

UniversalHash(SHA256(miner_address_utf8 || block_hash_32 || cyberlinks_merkle_32) || nonce_le_u64)

Use:

• lithium_header
• lithium_preimage
• lithium_hash
• meets_difficulty

Legacy UniversalHash v4 implementation is still present for compatibility tooling (UniversalHash, hash, v4 params), but it is non-canonical for lithium-v1 flow.

no_std Support

This crate supports no_std environments with the alloc crate:

[dependencies]
uhash-core = { version = "0.2", default-features = false }

Structs

LithiumCanonicalVector

Canonical lithium-v1 vector tuple shared across crates/tests.

Constants

LITHIUM_BLOCK_HASH_LEN

Fixed block hash length for lithium v1 preimage.

LITHIUM_CANONICAL_VECTORS

Shared canonical vectors used by core/web/consumer parity tests.

LITHIUM_CYBERLINKS_MERKLE_LEN

Fixed cyberlinks merkle length for lithium v1 preimage.

Functions

lithium_hash

Compute lithium v1 PoW hash using UniversalHash engine: UniversalHash(SHA256(miner_address || block_hash || cyberlinks_merkle) || nonce_le).

lithium_header

Build canonical lithium header bytes: SHA256(miner_address_utf8 || block_hash_32 || cyberlinks_merkle_32).

lithium_preimage

Build canonical lithium PoW input bytes: lithium_header || nonce_le_u64.

meets_difficulty

Check if a hash meets the required difficulty
