- "type": "TransferAssetContract"表示这是一个TRC10 Transfer
- "contractRet": "SUCCESS"表示成功，除了SUCCESS之外还有OUT_OF_ENERGY，表示能量不足。
- "asset_name": "31303034303331"为TRC10通证ID的HEX格式，将31303034303331转为ASCII或者Utf8字符串可得到1004031，1004031就是通证ID
- "amount": 7618406为Transfer数额，需要除以通证的10^精度 才是真实值
- owner_address为发送者地址的HEX格式
- to_address为接收者地址的HEX格式
- data是备注，转为Utf8即可看到备注文本，如果转账没备注则没这个字段
- 遗留问题：通证的精度从哪里解析？目前只能根据通证ID再去查一遍

- raw_data_hex包含2244a9059cbb为transfer方法转账，不包含则可能是其它function的智能合约触发
- "type": "TriggerSmartContract"表示当前为一个TRC20 Transfer
- "contractRet": "SUCCESS"表示成功，除了SUCCESS之外还有OUT_OF_ENERGY，表示能量不足。
- 第一个data是备注，转为Utf8即可看到备注文本，如果转账没备注则没这个字段
- owner_address为发送者地址的HEX格式
- contract_address为TRC20发行合约的HEX格式
- 第二个data参数，从第33位开始连续40位抽取出来（45c1098b64c646b2766ba322a704d12e709d7ba8），前面增加“41”即为收款人的地址HEX（4145c1098b64c646b2766ba322a704d12e709d7ba8）
- 第二个data参数，倒数64位为Transfer数量的16进制，转10进制除以该合约的10^精度 可得到真实数量
其它注意事项
- 有些TRC20 Transfer没有timestamp字段，例如：
703f7451e23293a629f8a5ddd62305bb2173d5efece482aef5d58d1f641752cb
这个时候可以用expiration这个时间戳 - 有些TRC20转账多了个call_value字段，这种不是常规的TRC20转账，第二个data字段也无法解析出相应信息，例如：
b00b60c2c25ec540b7a65456c4001881ceb36ee36992e57cd56da104c0ac8e5e
这个时候就放弃该条历史
如何获取所有区块上的接收者地址？
- 遍历，如果是TRX或TRC10，则直接把to_address转base58；如果是TRC20，判断不存在call_value后，第二个data参数，从第33位开始连续40位抽取出来，前面增加“41”再转base58即为接收者的地址
- 得到所有base58地址和对应的txID后，去跟数据库的地址取交集即需要记录历史信息的地址
