function

create 30a24abd

Creates a new blob. It is guaranteed that different users will never receive the same blobId, even before consensus has been reached. This prevents blobId sniping. Consider createWithNonce() if not calling from another contract.

Inputs0bytes4flags

Packed blob settings.

Inputs1bytescontents

Contents of the blob to be stored.

Outputs0bytes20blobId
function

createNewRevision a84c5330

Create a new blob revision.

Inputs0bytes20blobId

Id of the blob.

Inputs1bytescontents

Contents of the new revision.

Outputs0uint256revisionId
function

createWithNonce 6d1da953

Creates a new blob using provided nonce. It is guaranteed that different users will never receive the same blobId, even before consensus has been reached. This prevents blobId sniping. This method is cheaper than create(), especially if multiple blobs from the same account end up in the same block. However, it is not suitable for calling from other contracts because it will throw if a unique nonce is not provided.

Inputs0bytes32flagsNonce

First 4 bytes: Packed blob settings. The parameter as a whole must never have been passed to this function from the same account, or it will throw.

Inputs1bytescontents

Contents of the blob to be stored.
