还有心情来写文章和看文章的，也真是佛系了！

对以太坊交易结果检测一直存有疑问，再来从交易数据理一下。

数据比较

未打包前blockHash为0，blockNumber为null
打包后blockHash块哈希，blockNumber有块号
未打包无交易凭据，打包后有交易凭据（不管调用是否成功）
合约调用成功后交易凭据中logs会有数据（可能是事件数据，未再确定），但普通转帐交易凭据中logs无数据
合约调用成功后交易凭据中gasUsed可能小于gas，如果gas指定不足调用后gasUsed等于gas
合约调用input为调用数据，而普通转帐交易input为"0x"

交易结果检测

可以看出即使打包了，交易也未必成功。那怎么来判断结果呢？从网上找了有几种方法：

1、判断gas == gasUsed，如果相等则“Out of Gas”，但是好像有可能正常交易也会相等；
2、使用debug.traceTransaction判断

> var status = debug.traceTransaction("0x9ee86a200528de32a695f1e2dd0d94a3871fefc7e49c5fd24a4a37eab1b99f7a")
undefined
> status.structLogs[status.structLogs.length-1].error

3、从块4370000 (Byzantium)后可以通过"status"进行判断，为0失败，为1成功
