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, according to data from BTC.com. This marks the sixth consecutive increase in mining difficulty this year, reflecting growing competition among miners as the network's hash rate continues to climb. The adjustment comes just weeks before the highly anticipated Bitcoin halving event in April 2024, which will reduce block rewards from 6.25 BTC to 3.125 BTC. Analysts suggest miners are racing to maximize profits before the reward reduction, contributing to the rising difficulty. The current hash rate stands at approximately 639 EH/s, demonstrating the network's robust security despite market volatility. This upward trend in mining difficulty highlights Bitcoin's evolving ecosystem as it approaches a major supply shock event.
