    以太坊從PoW共識到PoS共識,應該是傷害一部分的人利益

    三貳春/文

    隨著加密貨幣挖礦消耗全球能量的問題日益嚴重,加密貨幣的“節能行動”正在有計劃地進行著。對于以太坊來說,目前有兩個目標是必須盡快地實現。

    第一個目標就是從PoW共識到PoS共識,實現全面節能計劃,事實上證實,PoW共識正消耗全球的能源,不只是消耗大量的電力能源,更會產生以億計的電子垃圾,已經不屬于“可持續發展”的范圍之內。

    PoW共識將會為挖礦消耗更大的能源,這一點正是尋求改變。

    PoS共識將會成為加密貨幣的未來。

    對于以太坊的第二個目標,就是分片技術,提高交易的速度,從現在每秒15個訂單的交易速度,提至更高的水平。

    本文章重點來談談PoS共識帶來的行業變化。

    在許多人眼前,從PoW共識到PoS共識僅僅是代碼的改變,其實多不止這些。

    首先,轉換為PoS共識,必須讓適應PoW共識的礦機實行銷毀措施,由此產生無數礦機變成廢銅爛鐵的事實,同樣這意味著礦工重新再來,這個成本和投資只能由礦工自己來消化掉。

    目前以太坊就這一個轉變計劃進行投票,目前依然有 huobi、firepool、uupool、pandapool等礦池投了放棄票。

    這似乎也證實了,以太坊算法轉型面臨著艱難選擇。有礦工不愿意拋棄已經到手的收益,ProgPoW算法的“礦機削弱計劃”面臨更大的博弈。

    “礦機削弱計劃”不會停止,只會多方妥協得到合理結果。目前已經有了新算法,比如“優化平民顯卡挖礦性能”和“抗 ASIC 礦機”的算法,來彌補基于PoW共識下的礦工損失。

    事實上,這樣的博弈和妥協的過程將是漫長著,很可能出現推動不下去的情況出現。

    以太坊的顯卡挖礦的算法,當ASIC 礦機之后,這種購買顯卡的成本將大大的增加,進一步傷害了礦工的收益。

    假如在PoW共識之下,以太坊將會玩完,至少以太坊核心團隊,再難以左右ETH的未來。
