PoW and mining

Mazze uses a Proof of Work scheme backed by RandomX hashing. Mining produces a nonce that satisfies a difficulty boundary.

Proof of Work primitives

• ProofOfWorkProblem bundles the block hash, difficulty, boundary, and seed.

• ProofOfWorkSolution carries the nonce.

• PowComputer computes the PoW hash with RandomX using a cached VM.

The boundary is derived from difficulty; a block is valid when pow_hash <= boundary.

RandomX cache and seed

PowComputer uses RandomXCacheBuilder to hold RandomX VMs and to swap context when the seed hash changes. This makes per-block hashing fast while still rotating the seed across epochs.

Difficulty adjustment

target_difficulty computes the next target from recent blocks, the configured block generation period, and the adjustment epoch period in ProofOfWorkConfig.

Mining modes

• CPU - local worker threads iterate nonces.

• Stratum - a job dispatcher hands work to external miners and validates submitted nonces.

• Disable - mining is turned off (used for read-only nodes or some dev modes).
