Bitcoin hashrate recovers after big freeze shuts down miners
Bitcoin’s network hashrate has returned to regular levels again, days after freezing temperatures across the United States put a strain on the nation's electricity grid — leading to a temporary drop in hashrate.
In the days leading up to Christmas, bone-chilling temperatures swept across the United States, leading to millions without power and claiming at least 28 lives.
According to reports, Bitcoin miners in Texas, which accounts for a significant portion of the country's hashrate, voluntarily curtailed operations to give power back to the grid — so that residents can keep their homes heated.
The disruptions appear to have put a dent in Bitcoin’s hashrate, which typically hovers around 225-300 Exahashes per second (EH/s). This fell to 170.60 EH/s on Dec. 25.
As of Dec. 26 however, the hashrate has returned to 241.29 EH/s, according to data from hashrate mining calculator CoinWarz.
Bitcoin’s hashrate is calculated by measuring the number of hashes produced by Bitcoin miners trying to solve the next block. It is regarded as a key metric in assessing how secure the Bitcoin network is.
The recent events prompted a controversial statement from FutureBit founder John Stefanop, who suggested the fall in hashrate was due to a number of “highly centralized mines” in Texas turning off at the same time.
“I know, does not change the fact that a few large mines in Texas affect the entire network to the tune of 33%...everyones transactions are now being confirmed 30% slower because the hashrate is not decentralized enough,” he said.
“If hashrate was distributed evenly around the world by 10’s of millions of small miners instead of a few dozen massive mines, this event would not have even registered on the network,” Stefanop added.
