private static final String BINARY = "0x6060604052341561000f57600080fd5b60d38061001d6000396000f3006060604052600436106049576000357c0100000000000000000000000000000000000000000000000000000000900463ffffffff16806360fe47b114604e5780636d4ce63c14606e575b600080fd5b3415605857600080fd5b606c60048080359060200190919050506094565b005b3415607857600080fd5b607e609e565b6040518082815260200191505060405180910390f35b8060008190555050565b600080549050905600a165627a7a72305820b287ea3878f6f6cc6e7e3885be10bd9172b2074fbdc32fbfc8f7edd3f683e8d90029";

这个binary值是哪里来的呢

这个命令是干嘛的?

make geth后
ln -s build/bin/geth /usr/bin/geth # 软链接
这个命令是干嘛的?ln: failed to create symbolic link '/usr/bin/geth': File exists

前辈你好!请教一个关于同步以太坊钱包数据格式问题

起因是我同步了以太坊钱包数据,生成了很多的ldb文件与cdat文件,我想读取.ldb与.cdat里面的合约数据,不过不知道怎样打开。下载下来的文件夹是这样的

这与我同步下来的几个文件很像,请问
000001.log

Ethereum

这个java版的helloworld的三种方式都ok,但既然是跑在以太坊上的,那怎么和本地的以太坊EthereumJ java版源码发生联系呢?我想在EthereumJ里打下log看看流程,比如挖矿和交易确认的代码是怎么确认的,两个项目是要在ide里建立依赖关系吗?

we couldn't estimate the gas

after click deploy,error tip like this:"it seems this transaction will fail,we couldn't estimate the gas",it may consume all the gas you provide.(钱包挖矿所得4665 ETHER)
钱包界面里没有gas设置,只有genesis.json里有 "gasLimit" : "0x2fefd8",.
想看下你的genesis.json

您好

您好 我是今天突然接到一个任务 需要做这方面的一个功能 想请问一下 如果我有多人注册 怎么获取不同的hash码呢 好像api上没有生成hash码的接口
