java - 在 XRP 中，当源账户 = 目标账户且源标签!= 目标标签时，错误是术语 REDUNDANT(将相同的货币发送给自己。)

Question

我正在尝试发送一些具有相同帐户但不同源和目标标签的 xrp。

@SuppressWarnings("unchecked")
@Override
public Map<String, Object> makeTransaction() {

    Map<String, Object> mainMap = new HashMap<>();


    mainMap.put("secret", "my_secret_key");
    mainMap.put("Fee", "1000"); // in drops

    Map<String, Object> subMap = new HashMap<>();
    subMap.put("Account", "my_ripple_account"); // source account(my_ripple_account) == destination account(my_ripple_account)
    subMap.put("Amount", "1000000"); // in drops

    subMap.put("Destination", "my_ripple_account"); // // source account(my_ripple_account) == destination account(my_ripple_account)

    subMap.put("TransactionType", "Payment"); // since we are making a payment request

    subMap.put("SourceTag", 400123);
    subMap.put("DestinationTag", 400555);

    mainMap.put("tx_json", subMap);

    JSONObject j = new JSONObject(mainMap);

    JSONObject json = new JSONObject();
    json.put("method", "submit");
    json.put("params", new JSONArray("[" + j.toString() + "]"));
    String requestData = json.toString();

    Map<String, Object> responseMap = restTemplate.postForObject("http://my_ip:5005",
            requestData, HashMap.class);

    LOGGER.debug("makeTransaction() : Response is {}.", responseMap);

    return responseMap;
}

示例说明: 这里源帐户(my_ripple_account)=目标帐户(my_ripple_account)并且sourceTag = 400123和destinationTag=400555。 所以这里用同一个账户进行交易。

示例输出:

    }
  }
}

输出说明: 输出表明 status=success 但 engine_result=temREDUNDANT 并且即使 status=success 标签余额也没有变化..

Answer 1

想象一下，如果您有一个钱包(真正的实体钱包)，里面有一些钞票。您正在做同样的事情，就好像您已经:

• 拿出你的钱包
• 拿出几张钞票
• 交换位置
• 将它们放回钱包

最终你仍然得到了和最初一样多的钱。
账单的顺序对您来说重要吗？
如果是，那么您可以自己跟踪它。 (您不会支付额外费用!)

这就是 Ripple 的帐户和目标标签模型的工作原理。
destinationTag 没有余额，它只是衡量您的交易差异化的指标。
