IL1DAValidator
Functions
checkDA
The function that checks the data availability for the given batch input.
function checkDA(
uint256 _chainId,
uint256 _batchNumber,
bytes32 _l2DAValidatorOutputHash,
bytes calldata _operatorDAInput,
uint256 _maxBlobsSupported
) external returns (L1DAValidatorOutput memory output);
Parameters
| Name | Type | Description |
|---|---|---|
_chainId | uint256 | The chain id of the chain that is being committed. |
_batchNumber | uint256 | The batch number for which the data availability is being checked. |
_l2DAValidatorOutputHash | bytes32 | The hash of that was returned by the l2DAValidator. |
_operatorDAInput | bytes | The DA input by the operator provided on L1. |
_maxBlobsSupported | uint256 | The maximal number of blobs supported by the chain. We provide this value for future compatibility. This is needed because the corresponding blobsLinearHashes/blobsOpeningCommitments in the L1DAValidatorOutput struct will have to have this length as it is required to be static by the circuits. |
