1、搭建私链，能够挖矿。

# cat /etc/bitcoin/bitcoin.conf
rpcuser=bitcoinrpc
rpcpassword=12345
maxconnections=1
regtest=1
datadir=/data/bitcoin
fallbackfee=0.000001
# bitcoind -conf=/etc/bitcoin/bitcoin.conf

2、掌握节点api。怎么查询最新高度，区块详情，交易详情。

查询最新高度

# bitcoin-cli -conf=/etc/bitcoin/bitcoin.conf -rpcwallet=test1 getdifficulty   挖坑难度
# bitcoin-cli -conf=/etc/bitcoin/bitcoin.conf -rpcwallet=test1  getblockcount  查询最新高度

查询区块详情

# bitcoin-cli -conf=/etc/bitcoin/bitcoin.conf -rpcwallet=test1 getnewaddress test2
