    Today we’re covering Bitcoin’s difficulty adjustment, Ethereum’s deflation simulation, and various community events happening in the PoW community!

    Learn about industry news, development updates, community happenings, and other aspects of the PoW world.

    Mining industry


    The latest difficulty adjustment happened Jul 18, 2021 with a -4.81% change. On the last 2-week cycle, the Bitcoin hashrate was stably climbing, producing the blocks with an average time of 10 mins 30 secs.

    Miners in this 2-week cycle harvested $0.30 per TH/s, 30% higher than the previous two weeks. This is a fairly profitable level and attracts more people pursuing hardware and consistently joining the network.
