function ValidateUTXOParameters

virtual bool ValidateUTXOParameters(
    const UTXOTxParameters & params,
    const std::string & address,
    const UTXOManager & utxo_manager
) const override

Validates ownership and structure of the supplied UTXO parameters.

Parameters:

  • params UTXO inputs and outputs carried by the transaction.
  • address Source address expected to own or authorize the inputs.
  • utxo_manager Local UTXO manager used for ownership and signature checks when required.

Return: True when the parameters are structurally valid for this source chain.

Reimplements: sgns::IInputValidator::ValidateUTXOParameters

function ValidateWitness

virtual bool ValidateWitness(
    const ConsensusSubject & subject,
    const std::shared_ptr< GeniusTransaction > & tx,
    const UTXOTxParameters & params,
    const std::shared_ptr< Blockchain > & blockchain
) const override

Validates the chain-specific witness data associated with a transaction input set.

Parameters:

  • subject Consensus subject that carries nonce, witness, and UTXO commitment data.
  • tx Transaction whose inputs and outputs are being validated.
  • params UTXO inputs and outputs carried by tx.
  • blockchain Blockchain service used to resolve producer certificates when required.

Return: True when the witness proves that params are valid for tx.

Reimplements: sgns::IInputValidator::ValidateWitness

function RequiresConsensusUTXOData

inline virtual bool RequiresConsensusUTXOData() const override

Indicates whether this validator requires consensus-provided UTXO data.

Return: True when the validator needs UTXO witness and commitment data from consensus.

Reimplements: sgns::IInputValidator::RequiresConsensusUTXOData

function Register

static inline bool Register()

Registers this validator in the global registry for the "migration" chain ID.

Return: true when the registration is done. This is used to ensure that the static instance is initialized and registered before main() starts.
