executeCertifyBlobTransaction method

Future<String> executeCertifyBlobTransaction({ required String blobId, required String blobObjectId, required bool deletable, ProtocolMessageCertificate? certificate, required SuiAccount signer, int? committeeSize, })

Execute a transaction that certifies a blob on-chain.

Requires the certificate from the upload relay or aggregated from individual storage node confirmations.

Returns the transaction digest.

Mirrors the TS SDK's executeCertifyBlobTransaction().

      'confirmations.',
