比特币现金BCH(BCC)

今天在VMware虚拟机的Ubuntu系统上安装了Bitcoin ABC后发现直接把之前安装的Bitcoin Core覆盖掉了，幸好安装Bitcoin ABC之前将虚拟机做了快照，快速还原回去了，只好重新建个虚拟机，安装Bitcoin ABC，用于测试。

BCH是由BTC硬分叉而来，因此很多操作可以参考BTC

一、编译安装Bitcoin ABC客户端

参照 Ubuntu下编译安装比特币Bitcoin 编译安装即可

二、使用Regtest测试网络

参照 在本机使用比特币Regtest测试网络

启动 regtest 网络

y@ubuntu:~$ bitcoind -regtest -txindex -daemon -deprecatedrpc=accounts
Bitcoin server starting

注意：加上 -deprecatedrpc=accounts 参数是为了可以使用 bitcoin-cli -regtest getaccountaddress “” 指令，否则会提示该指令已经过期

查看钱包默认账户的地址

y@ubuntu:~$ bitcoin-cli -regtest  getaccountaddress ""

挖矿

y@ubuntu:~$ bitcoin-cli -regtest generate 200

查看挖矿奖励

y@ubuntu:~$ bitcoin-cli -regtest getbalance
5000.00000000

分配一个新地址

y@ubuntu:~$ bitcoin-cli -regtest getnewaddress
bchreg:qq792pe74mrp947lzkmd0xfmwdlwcghz9cuq2032z2

向新地址中转账，这里转100个比特币

y@ubuntu:~$ bitcoin-cli -regtest sendtoaddress  bchreg:qq792pe74mrp947lzkmd0xfmwdlwcghz9cuq2032z2  100
