最新报道:Bitcoin mining difficulty has surged by 3.9% to reach a new all-time high of 86.39 trillion, according to recent blockchain data. This marks the fifth consecutive increase in mining difficulty this year, reflecting heightened competition among miners as the network adjusts to maintain a consistent block production rate. The adjustment follows Bitcoin's fourth halving event in April, which reduced block rewards by 50%. Despite the rising difficulty, Bitcoin's hash rate remains robust at around 630 EH/s, indicating sustained miner participation. Analysts note that efficient mining operations continue to thrive despite these challenges, with some firms upgrading equipment to maintain profitability.
