Package Contents#

class bittensor.utils.Certificate[source]#

Bases: str

str(object=’’) -> str str(bytes_or_buffer[, encoding[, errors]]) -> str

Create a new string object from the given object. If encoding or errors is specified, then the object must expose a data buffer that will be decoded using the given encoding and error handler. Otherwise, returns the result of object.__str__() (if defined) or repr(object). encoding defaults to sys.getdefaultencoding(). errors defaults to ‘strict’.

Initialize self. See help(type(self)) for accurate signature.

bittensor.utils.VersionCheckError[source]#
bittensor.utils.check_version[source]#
bittensor.utils.decode_hex_identity_dict(info_dictionary)[source]#

Decodes a dictionary of hexadecimal identities.

Parameters:

info_dictionary (dict[str, Any])

Return type:

dict[str, Any]

bittensor.utils.determine_chain_endpoint_and_network(network)[source]#

Determines the chain endpoint and network from the passed network or chain_endpoint.

Parameters:

network (str) – The network flag. The choices are: finney (main network), archive (archive network +300 blocks), local (local running network), test (test network).

Returns:

The network and chain endpoint flag. If passed, overrides the

network argument.

Return type:

tuple[Optional[str], Optional[str]]

bittensor.utils.float_to_u64(value)#

Converts a float to a u64 int

Parameters:

value (float)

Return type:

int

bittensor.utils.format_error_message(error_message)[source]#

Formats an error message from the Subtensor error information for use in extrinsics.

Parameters:

error_message (Union[dict, Exception]) – A dictionary containing the error information from Subtensor, or a SubstrateRequestException containing dictionary literal args.

Returns:

A formatted error message string.

Return type:

str

bittensor.utils.get_explorer_url_for_network(network, block_hash, network_map)[source]#

Returns the explorer url for the given block hash and network.

Parameters:
  • network (str) – The network to get the explorer url for.

  • block_hash (str) – The block hash to get the explorer url for.

  • network_map (dict[str, dict[str, str]]) – The network maps to get the explorer urls from.

Returns:

The explorer url for the given block hash and network. Or None if the network is not known.

Return type:

Optional[dict[str, str]]

bittensor.utils.get_hash(content, encoding='utf-8')[source]#
bittensor.utils.hex_to_bytes[source]#
bittensor.utils.is_valid_bittensor_address_or_public_key(address)[source]#

Checks if the given address is a valid destination address.

Parameters:

address (Union[str, bytes]) – The address to check.

Returns:

True if the address is a valid destination address, False otherwise.

Return type:

bool

bittensor.utils.is_valid_ss58_address(address)[source]#

Checks if the given address is a valid ss58 address.

Parameters:

address (str) – The address to check.

Returns:

True if the address is a valid ss58 address for Bittensor, False otherwise.

Return type:

bool

bittensor.utils.logging#
bittensor.utils.ss58_address_to_bytes(ss58_address)[source]#

Converts a ss58 address to a bytes object.

Parameters:

ss58_address (str)

Return type:

bytes

bittensor.utils.ss58_to_vec_u8(ss58_address)[source]#
Parameters:

ss58_address (str)

Return type:

list[int]

bittensor.utils.strtobool(val)[source]#

Converts a string to a boolean value.

truth-y values are ‘y’, ‘yes’, ‘t’, ‘true’, ‘on’, and ‘1’; false-y values are ‘n’, ‘no’, ‘f’, ‘false’, ‘off’, and ‘0’.

Raises ValueError if ‘val’ is anything else.

Parameters:

bittensor.utils.unlock_key(wallet, unlock_type='coldkey', raise_error=False)[source]#

Attempts to decrypt a wallet’s coldkey or hotkey

Parameters:
  • wallet (bittensor_wallet.Wallet) – a Wallet object

  • unlock_type – the key type, ‘coldkey’ or ‘hotkey’

  • raise_error – if False, will return (False, error msg), if True will raise the otherwise-caught exception.

Returns:

UnlockStatus for success status of unlock, with error message if unsuccessful

Raises:
