　开发指南：BUMO 存证 JAVA 开发指南 BUMO 存证 JAVA 开发指南 BUMO 开发概述 BUMO 是新一代商用级基础公链。通过创新的共识算法（BU Firework）、主链-imit = ();
　// Transaction initiation account"s nonce + 1
　Long nonce = 8L;
　 // Generate a new account to be activated
　Keypair keypair = ();
　((keypair, true));
　String destAccount = ();
　 // 1. Get the account address to send this transaction
　String activateAddresss = getAddressByPrivateKey(activatePrivateKey);
　 // 2. Build activateAccount
　AccountActivateOperation operation = new AccountActivateOperation();
　(activateAddresss);
　(destAccount);
　(initBalance);
　(activate account);
　 String[] signerPrivateKeyArr = {activatePrivateKey};
　// Record txhash for subsequent confirmation of the real result of the transaction.
　// After recommending five blocks, call again through txhash `Get the transaction information
　// from the transaction Hash"(see example: getTxByHash ()) to confirm the final result of the transaction
　String txHash = submitTransaction(signerPrivateKeyArr, activateAddresss, operation, nonce, gasPrice, feeLimit);
　if (txHash != null) {
　(hash: + txHash);
　}
　}

　记录存证信息 将存证信息记录在区块链上会被永久存储 获得账户的序列号 每个账户都维护着自己的序列号，该序列号从 1 起先，依次递增，一个序列号标记着一个该账户的交易 代码示例：
　public long getAccountNonce() {
　 long nonce = 0;
　 // Init request
　 String accountAddress = [资方账户地址];
　 AccountGetNonceRequest request = new AccountGetNonceRequest();
　 (accountAddress);
　// Call getNonce
　 AccountGetNonceResponse response = ().getNonce(request);
　 if (0 == ()) {
　 nonce = ().getNonce();
　 } else {
