这个binary值是哪里来的呢
你好 智能合约初学者 有相关问题请教。方便加个QQ么。281334589
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
Failed to execute goal org.web3j:web3j-maven-plugin:4.5.11:generate-sources (default-cli) on project demo: Could not compile solidity files
unrecognised option '--allow-paths'
您好,我这边下载源码,然后点击web3j:generate-sources后出现上述错误,请问有遇到过吗?谢谢

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?
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
部署的合约只在wallet下显示,0 of 12 confirmation,contract列表没有显示helloworld合约
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
创建用户之后,并没有生成对应的钱包文件是什么原因。
