bittensor.utils.registration.async_pow

bittensor.utils.registration.async_pow#

This module provides async utilities for solving Proof-of-Work (PoW) challenges in Bittensor network.

Functions#

create_pow_async(subtensor, wallet, netuid[, ...])

Creates a proof of work for the given subtensor and wallet.

Module Contents#

async bittensor.utils.registration.async_pow.create_pow_async(subtensor, wallet, netuid, output_in_place=True, cuda=False, dev_id=0, tpb=256, num_processes=None, update_interval=None, log_verbose=False)#

Creates a proof of work for the given subtensor and wallet.

Parameters:

  • subtensor (bittensor.core.async_subtensor.AsyncSubtensor) – The subtensor instance.

  • wallet (bittensor_wallet.Wallet) – The wallet to create a proof of work for.

  • netuid (int) – The netuid for the subnet to create a proof of work for.

  • output_in_place (bool) – If true, prints the progress of the proof of work to the console in-place. Meaning the progress is printed on the same lines.

  • cuda (bool) – If true, uses CUDA to solve the proof of work.

  • dev_id (Union[list[int], int]) – The CUDA device id(s) to use. If cuda is true and dev_id is a list, then multiple CUDA devices will be used to solve the proof of work.

  • tpb (int) – The number of threads per block to use when solving the proof of work. Should be a multiple of 32.

  • num_processes (int) – The number of processes to use when solving the proof of work. If None, then the number of processes is equal to the number of CPU cores.

  • update_interval (int) – The number of nonces to run before checking for a new block.

  • log_verbose (bool) – If true, prints the progress of the proof of work more verbosely.

Returns:

The proof of work solution or None if the wallet is already registered or there is a different error.

Raises:

ValueError – If the subnet does not exist.

Return type:

bittensor.utils.registration.POWSolution
