币界网报道：Bitcoin mining difficulty has surged by 3.9% to reach a new all-time high of 88.1 trillion hashes, marking the sixth consecutive increase this year. The adjustment occurred at block height 842,688, reflecting growing competition among miners as the network's hash rate continues to climb. This rise in difficulty comes just weeks before the Bitcoin halving event, which will reduce block rewards from 6.25 BTC to 3.125 BTC per block. The current hash rate stands at approximately 639 EH/s, demonstrating the network's robust security despite recent price volatility. Analysts suggest miners are racing to maximize profits ahead of the halving, contributing to the intensified competition. The next difficulty adjustment is expected around April 24, 2024, potentially bringing further changes to the mining landscape.
