Bitcoin's daily hashrate reached an all-time high of 1.279 zettahashes per second (ZH/s) on Tuesday, according to CoinWarz data. The 7-day moving average hashrate also surpassed 1 ZH/s for the first time. This surge comes as miners face increasing energy costs and the upcoming block reward halving to 3.125 BTC. In response to these pressures, some major mining companies are exploring high-performance computing ventures to mitigate revenue fluctuations.
