开发者用 M1 挖矿,每天挣 1 块钱(代码已开源)

一般来说,在高端显卡上挖矿是收益最高的。随着虚拟货币行情的高涨,很多因疫情接近停业的网吧甚至已经转向挖矿为生,借助装有高性能显卡的电脑,获得比正常营业更高的收益。
但极客们常常愿意尝试新的方法,比如 —— 手头最新购入的 M1 电脑。
前些天,Zensors 软件工程师 Yifan Gu 成功在自己搭载 M1 芯片的 MacBook Air 上运行了挖矿程序,并且开源了代码。如果你手上也有一台 M1,不妨试试。
项目地址:https://github.com/gyf304/ethminer-m1
不过,先给出博主的最终结论:「不大好使」。
挖矿方法
Yifan Gu 在个人博客中展示了挖矿的全部过程,在 M1 Mac 上运行 Ethereum 软件,哈希率是 2Mh/s。
