5.3 Weight Submission

Tempo-Aligned Cadence​

# validator/weight_setter.py
TEMPO              = subtensor.get_subnet_hyperparameters(netuid).tempo
WEIGHTS_RATE_LIMIT = subtensor.get_subnet_hyperparameters(netuid).weights_rate_limit

if (current_block - last_set_block >= TEMPO
        and current_block - last_set_block >= WEIGHTS_RATE_LIMIT):
    subtensor.set_weights(
        netuid=netuid,
        uids=miner_uids,
        weights=normalised_weights,
        wait_for_inclusion=False,
    )
    last_set_block = current_block

Async Query Loop​

# validator/query_loop.py
QUERY_TIMEOUT_S = 9   # must be < 12 s (1 block)

async def query_miners(dendrite, axons, synapse, send_block):
    responses = await dendrite.forward(
        axons=axons, synapse=synapse, timeout=QUERY_TIMEOUT_S,
    )
    for r in responses:
        r.send_block = send_block
    return responses

send_block is stamped at dispatch time so scores are attributed to the correct task regardless of network delay.
