不久前刚在OpenEuler 24.09 RISC-V上部署了 bitcoin,不过还没跑起来,这次我打算在这个环境下面运行一些应用服务,体验一下 OERV 的开发感觉。
编译出来的 bitcoin 主要有几个命令,bitcoin-cli、bitcoind、bitcoin-util、bitcoin-wallet、bitcoin-tx和test_bitcoin。
bitcoind 是比特币核心软件的守护进程程序,用于在计算机上运行比特币全节点。它是比特币网络的基础组件,负责下载、验证和存储整个比特币区块链,并与其他节点进行通信。
bitcoin-cli 是一个命令行工具,用于与运行中的 bitcoind 守护进程进行交互。通过它,用户可以方便地向 bitcoind 发送各种请求,执行各种操作,如查询区块链信息、管理钱包、发起交易等。
bitcoind-util 包含了一系列比特币相关的实用工具函数和命令,主要用于处理比特币的基础数据,如地址编码、密钥生成、哈希计算等。
bitcoin-wallet 主要用于管理比特币钱包,它提供了一系列与钱包操作相关的功能,帮助用户方便地存储、发送和接收比特币。
bitcoin-tx 是一个用于处理比特币交易的工具,主要用于创建、编辑、签名和广播比特币交易。
test_bitcoin 是比特币核心软件的测试工具,用于对 bitcoind 及相关组件进行单元测试和集成测试,确保代码的正确性和稳定性。
用法有很多,我主要挑了 bitcoind 和 bitcoin-cli 进行测试,看看运行的时候有没有什么 bug。
bitcoind,光执行这个命令,会输出一大堆服务器的信息
不过我们也可以选择挂到后台,bitcoind -daemon
这样就可以利用控制台继续做其它事情了。如果想停下来,可以用 bitcoin-cli stop对服务器进行终止。
bitcoin-cli 获取到的信息大部分都是以 json 的形式返回,以下是测试结果。
bitcoin-cli getnetworkinfo(获取区块链网络信息)
{"version": 299900,"subversion": "/Satoshi:29.99.0/","protocolversion": 70016,"localservices": "0000000000000c09","localservicesnames": ["NETWORK","WITNESS","NETWORK_LIMITED","P2P_V2"],"localrelay": true,"timeoffset": 0,"networkactive": true,"connections": 8,"connections_in": 0,"connections_out": 8,"networks": [{"name": "ipv4","limited": false,"reachable": true,"proxy": "","proxy_randomize_credentials": false},{"name": "ipv6","limited": false,"reachable": true,"proxy": "","proxy_randomize_credentials": false},{"name": "onion","limited": true,"reachable": false,"proxy": "","proxy_randomize_credentials": false},{"name": "i2p","limited": true,"reachable": false,"proxy": "","proxy_randomize_credentials": false},{"name": "cjdns","limited": true,"reachable": false,"proxy": "","proxy_randomize_credentials": false}],"relayfee": 0.00001000,"incrementalfee": 0.00001000,"localaddresses": [],"warnings": ["This is a pre-release test build - use at your own risk - do not use for mining or merchant applications"]
}
bitcoin-cli getblockchaininfo(获取当前的区块链信息,每次输出可能不一样,因为区块链信息可能还没有同步完成到本地,另一方面,区块是不断生成的)
{"chain": "main","blocks": 16848,"headers": 890116,"bestblockhash": "00000000e84734ddbfcae5a7a3438cbc69498fab0f3097c5f866f617d019ab60","bits": "1d00ffff","target": "00000000ffff0000000000000000000000000000000000000000000000000000","difficulty": 1,"time": 1244664175,"mediantime": 1244660177,"verificationprogress": 1.44758331039791e-05,"initialblockdownload": true,"chainwork": "000000000000000000000000000000000000000000000000000041d141d141d1","size_on_disk": 4791214,"pruned": false,"warnings": ["This is a pre-release test build - use at your own risk - do not use for mining or merchant applications"]
}
bitcoin-cli getmininginfo(获取挖矿信息)
{"blocks": 37920,"bits": "1d00be71","difficulty": 1.344224970771029,"target": "00000000be710000000000000000000000000000000000000000000000000000","networkhashps": 16012268.79171674,"pooledtx": 0,"chain": "main","next": {"height": 37921,"bits": "1d00be71","difficulty": 1.344224970771029,"target": "00000000be710000000000000000000000000000000000000000000000000000"},"warnings": ["This is a pre-release test build - use at your own risk - do not use for mining or merchant applications"]
}
另一方面,如果输出一个错误的命令,比如 bitcoin-cli abc,会有错误码机制。
error code: -32601
error message:
Method not found
bitcoin-cli createwallet "my_wallet"(创建名字为"my_wallet"的钱包)
{"name": "my_wallet"
}
bitcoin-cli -rpcwallet=my_wallet getnewaddress(会为刚刚创建的钱包创建一个地址)
综上来看,bitcoin 应用测试看起来一切顺利,尽管我只测试了最基本的命令行,但这也是探索过程中好的开始。
