Ethereum PoS合并能源消耗减少了99.84%,至99.99%,每一篇新论文发表模式,节省的能量合并的权力被爱尔兰、奥地利等国家。在合并之前,Ethereum mainnet用来运行在Proof-of-Work(战俘)共识机制中“矿工”作为网络上的节点和处理事务。矿业ETH区块链是一个有限的过程,并要求矿工使用显卡等计算设备和专业出版社的机器。面向消费者的gpu,可能大部分的矿工,是power-inefficient时挖掘。个体矿工有时数以百计的这些卡在一个设施。Ethereum矿业越来越受欢迎和hashrate(电源连接到网络)的总量迅速增长,问题逐渐开始提高的能源消费链,和它的环境影响。为了缓解这个问题,ETH社区决定开关Proof-of-Stake系统(PoS)的共识。与战俘,网络这种机制不使用矿工使用的计算能力,互相竞争。相反,这里的节点,称为“stakers”,只需要锁一定数量的硬币(至少32 ETH具体)的铆合合同,需要一个低功率计算设备成为一个验证节点在网络上。今年9月15日,合并发生,成功完成Ethereum PoS-based系统的过渡。 As for the actual amount of power used by the network before the Merge, the study cites several estimates based on various scenarios. Estimates of ETH power consumption under different conditions | Source: Patterns Making the assumption that all miners used the most-efficient mining machine available, Ethereum’s pre-PoS power consumption comes out to be around 418 MW. However, as mentioned before, not many miners actually used the efficient AISC machines; GPUs were more popular. Using the highest end GPU available before the Merge (the Nvidia RTX 3090Ti) puts the power estimate at 2.23 GW, significantly higher than the other figure. In reality, miners used a mixed variety of mining rigs and there were also other power expenses involved like cooling in the facilities, which means the actual value should be much higher than this. “A tracker by Kyle McDonald estimated Ethereum’s power demand at 2.44 GW before The Merge,” notes the report. In the worst scenario, where miners broke just even on their mining and made no profits, the approximate power used comes out be 9.21 GW. Compared to these extremely large numbers for energy consumption prior to the Merge, the study puts post-PoS power lower bound at 36 kW and upper bound at 675 kW. This means that the PoS switch has reduced the power usage by a whopping 99.84% (in the best-to-worst case scenario) to 99.99% (assuming the worst-to-best case). “In absolute terms, the reduction in power demand could be equivalent to the electrical power requirement of a country such as Ireland or even Austria,” the paper puts into perspective. ETH Price At the time of writing, Ethereum’s price floats around $1.2k, down 3% in the last week.
