bittensor.core.extrinsics.commit_weights#

Module commit weights and reveal weights extrinsic.

Functions#

`commit_weights_extrinsic`(subtensor, wallet, netuid, ...)	Commits a hash of the neuron's weights to the Bittensor blockchain using the provided wallet.
`do_commit_weights`(self, wallet, netuid, commit_hash[, ...])	Internal method to send a transaction to the Bittensor blockchain, committing the hash of a neuron's weights.
`do_reveal_weights`(self, wallet, netuid, uids, values, ...)	Internal method to send a transaction to the Bittensor blockchain, revealing the weights for a specific subnet.
`reveal_weights_extrinsic`(subtensor, wallet, netuid, ...)	Reveals the weights for a specific subnet on the Bittensor blockchain using the provided wallet.

Module Contents#

bittensor.core.extrinsics.commit_weights.commit_weights_extrinsic(subtensor, wallet, netuid, commit_hash, wait_for_inclusion=False, wait_for_finalization=False)#

Commits a hash of the neuron’s weights to the Bittensor blockchain using the provided wallet. This function is a wrapper around the do_commit_weights method.

Parameters:

subtensor (bittensor.core.subtensor.Subtensor) – The subtensor instance used for blockchain interaction.
wallet (bittensor_wallet.Wallet) – The wallet associated with the neuron committing the weights.
netuid (int) – The unique identifier of the subnet.
commit_hash (str) – The hash of the neuron’s weights to be committed.
wait_for_inclusion (bool) – Waits for the transaction to be included in a block.
wait_for_finalization (bool) – Waits for the transaction to be finalized on the blockchain.

Returns:

True if the weight commitment is successful, False otherwise. And msg, a string value describing the success or potential error.

Return type:

tuple[bool, str]

This function provides a user-friendly interface for committing weights to the Bittensor blockchain, ensuring proper error handling and user interaction when required.

bittensor.core.extrinsics.commit_weights.do_commit_weights(self, wallet, netuid, commit_hash, wait_for_inclusion=False, wait_for_finalization=False)#

Internal method to send a transaction to the Bittensor blockchain, committing the hash of a neuron’s weights. This method constructs and submits the transaction, handling retries and blockchain communication.

Parameters:

self (bittensor.core.subtensor.Subtensor) – The subtensor instance used for blockchain interaction.
wallet (bittensor_wallet.Wallet) – The wallet associated with the neuron committing the weights.
netuid (int) – The unique identifier of the subnet.
commit_hash (str) – The hash of the neuron’s weights to be committed.
wait_for_inclusion (bool) – Waits for the transaction to be included in a block.
wait_for_finalization (bool) – Waits for the transaction to be finalized on the blockchain.

Returns:

A tuple containing a success flag and an optional error message.

Return type:

tuple[bool, Optional[str]]

This method ensures that the weight commitment is securely recorded on the Bittensor blockchain, providing a verifiable record of the neuron’s weight distribution at a specific point in time.

bittensor.core.extrinsics.commit_weights.do_reveal_weights(self, wallet, netuid, uids, values, salt, version_key, wait_for_inclusion=False, wait_for_finalization=False)#

Internal method to send a transaction to the Bittensor blockchain, revealing the weights for a specific subnet. This method constructs and submits the transaction, handling retries and blockchain communication.

Parameters:

self (bittensor.core.subtensor.Subtensor) – The subtensor instance used for blockchain interaction.
wallet (bittensor_wallet.Wallet) – The wallet associated with the neuron revealing the weights.
netuid (int) – The unique identifier of the subnet.
uids (list[int]) – List of neuron UIDs for which weights are being revealed.
values (list[int]) – List of weight values corresponding to each UID.
salt (list[int]) – List of salt values corresponding to the hash function.
version_key (int) – Version key for compatibility with the network.
wait_for_inclusion (bool) – Waits for the transaction to be included in a block.
wait_for_finalization (bool) – Waits for the transaction to be finalized on the blockchain.

Returns:

A tuple containing a success flag and an optional error message.

Return type:

tuple[bool, Optional[str]]

This method ensures that the weight revelation is securely recorded on the Bittensor blockchain, providing transparency and accountability for the neuron’s weight distribution.

bittensor.core.extrinsics.commit_weights.reveal_weights_extrinsic(subtensor, wallet, netuid, uids, weights, salt, version_key, wait_for_inclusion=False, wait_for_finalization=False)#

Reveals the weights for a specific subnet on the Bittensor blockchain using the provided wallet. This function is a wrapper around the _do_reveal_weights method.

Parameters:

subtensor (bittensor.core.subtensor.Subtensor) – The subtensor instance used for blockchain interaction.
wallet (bittensor_wallet.Wallet) – The wallet associated with the neuron revealing the weights.
netuid (int) – The unique identifier of the subnet.
uids (list[int]) – List of neuron UIDs for which weights are being revealed.
weights (list[int]) – List of weight values corresponding to each UID.
salt (list[int]) – List of salt values corresponding to the hash function.
version_key (int) – Version key for compatibility with the network.
wait_for_inclusion (bool) – Waits for the transaction to be included in a block.
wait_for_finalization (bool) – Waits for the transaction to be finalized on the blockchain.

Returns:

True if the weight revelation is successful, False otherwise. And msg, a string value describing the success or potential error.

Return type:

tuple[bool, str]

This function provides a user-friendly interface for revealing weights on the Bittensor blockchain, ensuring proper error handling and user interaction when required.
