use of com.jd.blockchain.transaction.DigitalSignatureBlob in project jdchain-core by blockchain-jd-com.

the class LedgerTransactionDataTest method initTxRequestMessage.

private TxRequestMessage initTxRequestMessage(CryptoAlgorithm hashAlgorithm) throws Exception {
    TransactionContent txContent = initTransactionContent();
    HashDigest txHash = TxBuilder.computeTxContentHash(hashAlgorithm, txContent);
