The Bitcoin network hashrate rose 4% in the first two weeks of the month to an average of 937 exahashes per second (EH/s), Wall Street bank JPMorgan (JPM) said in a research report Monday.
The hashrate refers to the total combined computational power used to mine and process transactions on a proof-of-work blockchain, and is a proxy for competition in the industry and mining difficulty.
The combined hashrate of the 13 U.S.-listed miners the bank tracks rose 94% year-on-year, almost double the 48% increase in the network hashrate. The U.S. miners now account for 33.6% of the global figure, the highest level on record.
