2 R9 b$ @; g7 [ a2 I! o近日，比特币全网算力出现显著下降，根据Blockchain.com的数据，从上周五的约4 C: z# H) Q" Y: B1 O
600EH/s降至昨日的440EH/s，跌幅高达25%。这主要是因为美国德州面临严重寒流，导致当地电WJ管机构6 Z% l, X# g; W ~0 g. e" T, ^

8 I. i$ a2 u WThe Miner Mag先前报导指出，这次算力下降主要由Foundry USA Pool引起，该矿池的矿工客户减少了高达: q9 P6 p, X9 L" }" b- N' X5 o
75EH/s的算力。而截至9月份，连接到Foundry矿池的算力中有超过28%位于德州，因此这次算力下降与德州的% `1 t5 P% K- C: `. @/ k

截至目前，随着ERCOT在今日凌晨宣布结束天气警报，Foundry USA Pool和蚂蚁矿池的算力已分别回升至5 b4 E' v' m7 I! S

这次事件除了凸显地方制策对比特币挖矿活动的影响外，也彰显出比特币挖矿活动「可便利中断操作」的独特优4 A+ s( F# s6 T# @" R& l
势。受此影响的北美3大矿企之一，Marathon Digital的企业传播副总裁查理·舒马赫表示：比特币矿机在很多方5 H4 B0 u7 B. X! { X: _

值得一提的是，德州是天朝自2021年打击挖矿产业后，迅速崛起成为比特币挖矿的新枢纽。矿工认为，他们的挖
