最近bsv被大规模的51%攻击，导致该链有多达三个版本被同时挖矿。当年，bsv攻击bch，迫使bch加入了重组保护，被bsv嘲笑。这次bsv的遭遇要糟糕的多，建议加上bch的重组保护方案。

BCH侧链smartBCH最近已经悄然上线，看目前的情况，BCH可能会在以后更受欢迎，今天这篇文章带大家了解一下BCH开发网的部署。

其实以前也写过关于bch链开发网的文章，但这次使用的是bch链最新版本进行部署的，里面的启动参数以及rpc接口已经有所改变。这些变化一般都会在有新版本时，在github中有所体现，所以大家在升级版本的时候，一定注意这些升级的版本都有什么变化，切勿造成线上环境问题。

一、bch镜像生成

  • 1.下载基础镜像
docker pull buildpack-deps:jessie-curl
  • 2.编写Dockerfile
# vim Dockerfile 

FROM buildpack-deps:jessie-curl   
RUN wget -O bchn.tar.gz https://github.com/bitcoin-cash-node/bitcoin-cash-node/releases/download/v23.0.0/bitcoin-cash-node-23.0.0-x86_64-linux-gnu.tar.gz \
        && tar -xzvf bchn.tar.gz \
        && cd bitcoin-cash-node-23.0.0/bin \
        && mv bitcoin-cli bitcoin-tx bitcoind /usr/local/bin \
        && cd / \
        && rm -Rfv bitcoin*
EXPOSE 18443 18444
WORKDIR /root/.bitcoin
ENTRYPOINT ["bitcoind"]


注：EXPOSE用来指定端口，使容器内的应用可以通过端口和外界交互。18443为rpc远程调用协议的端口，18444为其他节点同步端口，BCH默认本地私有链的端口为：18443、18444，所以此处端口可指定为：18443、18444。


  • 3.构建镜像
docker build . -t bch/bitcoin-cash-node:v23.0.0
  • 4.查看镜像
# docker images
REPOSITORY               TAG                 IMAGE ID            CREATED             SIZE
bch/bitcoin-cash-node    v23.0.0             5eba9aaea795        8 seconds ago       212MB

二、bch容器生成

  • 1.创建bch数据目录
mkdir -p /opt/docker/bch-regtest/data
  • 2.启动bch开发网容器
docker run -itd --restart=unless-stopped -v /etc/localtime:/etc/localtime -v /etc/timezone:/etc/timezone --name bchn-regtest -v /opt/docker/bch-regtest/data:/root/.bitcoin/regtest -p 18443:18443 -p 18444:18444 bch/bitcoin-cash-node:v23.0.0 -regtest -server=1 -rpcuser=admin -rpcpassword=123456 -txindex=1 -paytxfee=0.00005 -rpcport=18443 -rpcallowip=0.0.0.0/0 -port=18444 -rpcbind=0.0.0.0:18443

参数解释


-regtest： 表示启动的是 regtest 网络；不同网络之间的区别在于创世区块不同,如果部署测试网，参数应为：-testnet，默认为主网



-txindex=1： 表示对所有的交易进行索引；否则默认只对与钱包地址有关的交易索引（使 getrawtransaction rpc 可调用完整的事务索引）



-server=1：表示接受命令行和JSON-RPC命令



-paytxfee=0.0005：手续费率指定，此参数表示：0.00005 BCHA/kB



-rpcuser=admin：JSON-RPC连接的用户名



-rpcpassword=123456：JSON-RPC连接的密码



-rpcport=18443：JSON-RPC连接的端口（默认default（main）: 8332, testnet:18332, regtest: 18443）



-rpcallowip=0.0.0.0/0：允许来自指定源的JSON-RPC连接，可指定单个IP或一个网段，此选项可以指定多次



-rpcbind=0.0.0.0:18443：绑定到给定的地址来监听JSON-RPC连接



-port=18444：p2p监听连接的端口，用于区块链节点间的通信（default（main）: 8333, testnet: 18333, regtest: 18444）


三、查看bch服务是否部署成功

  • 查看容器是否成功启动
# docker ps
CONTAINER ID        IMAGE                           COMMAND                  CREATED             STATUS              PORTS                                                                    NAMES
606daa0991e3        bch/bitcoin-cash-node:v23.0.0   "bitcoind -regtest -…"   19 minutes ago      Up 19 minutes       0.0.0.0:18443-18444->18443-18444/tcp                                     bchn-regtest

四、常用接口使用

原来也写过BCH链的rpc常用接口的使用方法

  • 创建地址 getnewaddress
# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getnewaddress", "params": ["test2"] }' -H 'content-type: text/plain;' http://127.0.0.1:18443
{"result":"bchreg:qz9qwcwqd3jrt669dvjg32pyd5kmh2x8zyvflejunj","error":null,"id":"curltest"}
  • 出块 generatetoaddress


注：BCH节点106块时产生出块收益


# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "generatetoaddress", "params": [6,"qz9qwcwqd3jrt669dvjg32pyd5kmh2x8zyvflejunj"] }' -H 'content-type: text/plain;' http://127.0.0.1:18443

  • 获取最新区块高度 getblockcount

{"result":106,"error":null,"id":"curltest"}
  • 显示bch钱包中所有地址余额 listaddressgroupings
# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "listaddressgroupings", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:18443
{"result":[[["bchreg:qz9qwcwqd3jrt669dvjg32pyd5kmh2x8zyvflejunj",100.00000000,"test2"]]],"error":null,"id":"curltest"}
  • 发送金额至指定地址 sendtoaddress
# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "sendtoaddress", "params": ["qr03h5ewa07jp4lpme4qmjdzc244c480mqhjkes9vq",10] }' -H 'content-type: text/plain;' http://127.0.0.1:18443

  • 查询未花费输出 listunspent
# curl --user admin:123456 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "listunspent", "params": [6, 9999999, ["qz9qwcwqd3jrt669dvjg32pyd5kmh2x8zyvflejunj"]] }' -H 'content-type: text/plain;' http://127.0.0.1:18443
