跟风用 #AWS#ETH Image
GPU挖 #ETH ,CPU挖 #XMR Image
通过充分利用CPU和GPU,目前100美刀的服务器成本可以挖80美刀的币(ETH和XMR),相信存在某种组合模型可以将挖币损失率控制在10%内。通过限制服务器竞价成本,动态调整挖币的种类,估计可以逼近无损挖矿的理想情况。
一开始我看的文章测试说单纯挖ETH的挖矿损失率高达40%,但是多币同时挖,最高利用CPU的核心和GPU,然后控制服务器竞价的成本,可以不断的降低成本,提高收益率。目前GPU的利用率只有50%,看起来还可以进一步提高,我感觉通过优化可以让损失率降低到10%
挖矿这里面的东西还挺复杂的,花样繁多,包括挖矿矿工的收益分配机制的研究,还有挖矿参数的调优,就需要不断的测试,包括币价本身的波动,服务器价格的波动,都是一系列关联的参数模型。由于我的服务器是spot类型,到了晚上(美国的白天)价格就涨起来了,导致晚上几乎买不到服务器,只有大半天在挖
没想到币价暴跌时挖矿收益反而最高,因为暴跌导致交易量激增,区块交易费激增导致挖矿收益也涨了不少,现在币价稳定后用Azure挖也有小幅亏损了(14个v100每天成本120美刀左右)。 Image
算了下我所在的矿池总算力是120多TH/S,是我现在算力的95000多倍,那差不多这个矿池矿工全部用服务器挖的话是一天1300多万美刀,是不是可以理解为以太坊生态运转一天的部分成本。不知道和传统银行运转成本相比是高还是低。
