Model Signature

Model Signature#

rizemind.authentication.notary.model.model_signature.hash_parameters(parameters: Parameters) → bytes[source]#

Hashes the Parameters dataclass using keccak256.

Parameters:

parameters – The model parameters to hash.

Returns:

The keccak256 hash of the concatenated tensors and tensor type.

rizemind.authentication.notary.model.model_signature.recover_model_signer(*, model: Parameters, round: int, domain: EIP712DomainRequiredFields, signature: Signature) → ChecksumAddress[source]#

Recover the address of the signed model.

Parameters:

  • model – The model’s parameters.

  • round – The current round number of the federated learning.

  • domain – The EIP712 required fields.

  • signature – The signature of the trainer/aggregator that sent the parameters.

Returns:

The hex address of the signer.

rizemind.authentication.notary.model.model_signature.sign_parameters_model(*, parameters: Parameters, round: int, domain: EIP712DomainRequiredFields, account: BaseAccount) → Signature[source]#

Signs a model’s parameters using the EIP-712 standard.

@TODO -> requires double checking with domain :param account: An Ethereum account object from which the message will be signed. :param parameters: The model parameters to sign. :param domain: The EIP712 required fields. :param round: The current round number of the federated learning.

Returns:

The SignedMessage from eth_account
