Bitcoin mining became 7.3% more difficult today after the network’s latest fortnightly change, according to data on BTC.com. It’s the second positive adjustment since China’s mining crackdown sent Bitcoin’s hash rate down by 55%, cutting the difficulty level in half.
Bitcoin miners are powerful computers that compete to solve the complex equations necessary to verify transactions on the Bitcoin network. In return for their efforts, the Bitcoin blockchain rewards miners with newly-minted Bitcoin.
Bitcoin’s mining difficulty measures how much computational power is required to mine Bitcoin. The blockchain adjusts the difficulty after every 2016 blocks are mined, roughly every two weeks, to account for the varying amount of computational power backing the network.
Today’s difficulty adjustment is the second consecutive positive adjustment. Bitcoin became 6% more difficult to mine after the last adjustment on July 31. The positive trend is nowhere near that of mid-May, when Bi
