上周,以太坊宣布了它在今年夏天过渡到权益证明之前的最后一次测试。ETH 的 PoS 合并为工作量证明系统提供了多项改进。
权益证明 (PoS) 是一种共识算法,在该算法中,具有“权益”的本机平台令牌的节点负责验证新交易。通常在这些网络中,节点拥有的权益越多,验证区块和验证区块的机会就越高。相比之下,工作量证明 (PoW) 网络解决密码难题(交付工作)以验证交易。PoW 最初是作为对抗垃圾邮件和拒绝服务攻击的一种措施提出的。
来自去中心化区块链协议Minima的 Jonathan MacDonald 对以太坊向权益证明的运动发表评论 。
根据Digiconomist的数据,以太坊每年使用 113 太瓦时——与荷兰一样多 。单次以太坊交易消耗的电量相当于美国普通家庭一周多的电量。比特币的能耗 更差。不出所料,这些统计数据来自对工作量证明 (PoW) 的批评,原因是能源消耗和对特定硬件的要求,这些硬件在几年后就过时了,可能会填满垃圾填埋场。以太坊需要转向权益证明(PoS),这样它就不会进一步加剧比特币的环境恐怖,并将每秒交易量从今天的每秒 30 次左右增加。
通常,PoS 网络不会消耗太多能量来保护网络,但电子垃圾的风险可能同样高。此外,在 PoS 中,投资越多的人赚的钱越多。以太坊作为验证者的成本设定为 32ETH,问题是这是否是一个公平的、去中心化的竞争环境——或者基本上,只是银行的另一个版本?
