B3 setup

1. power cable Connection
2. network cable Connection
3. power up
4. discover the device's IP address

• windows: 找IP, may need to press the "IP report" button on the device
• smart phone: fing in App/Google store, and look for "antminer"
• linux/mac: 'ping antminer'

5. visit the ip address (or http://antminer/) in a broswer

• 什么是拒绝数？拒绝率？
  • 根据矿池的工作原理，矿池不断给矿机下发新的计算任务，矿机将计算结果提交给矿池。但是由于矿机与矿池的网络连接是有延迟的，从矿池下发新的挖矿高度的任务给矿机，到矿机接收到任务，在这段时间提交的结果已经过时，将不被矿池承认。拒绝率即无效提交与总提交结果之比。
  • 拒绝数是指矿机提交的算力不符合服务器要求，被服务器拒绝的工作量。拒绝率是指拒绝数占总提交数的比例，数值越小，矿机的工作效率就越高。
• 幸运值
  • 每个区块的幸运值是矿池实际工作量与挖矿难度之比。如果工作量小于难度，说明运气比较好，幸运值就越高。挖矿的运气成分很大，幸运值发生波动也很常见，但挖矿时间越久，总幸运值越接近 100%。
• 结算方式
  • PPS
    • 收益稳定，只要矿机正常工作就有收益，收益和提交的工作量有关，和矿池幸运值、交易手续费无关
• PPS+

config the node

• when testing, could try switching to the testnet or solonet
  • ./bytomd init --chain_id testnet
  • or ./bytomd init --chain_id solonet , with a lower difficulty, in order to mine with cpu
• could use -r "your/directory" to specify the data directory when init with init or run with node
  • the directory will be created if not existed
