最新报道:Bitcoin mining difficulty has surged by 3.9% to reach a new all-time high of 88.1 trillion hashes, according to recent blockchain data. This marks the sixth consecutive increase in difficulty this year, reflecting heightened competition among miners as more participants join the network. The adjustment follows Bitcoin's fourth halving event, which reduced block rewards from 6.25 BTC to 3.125 BTC. Despite the reduced rewards, miners continue to invest in more efficient hardware to maintain profitability. The rising difficulty underscores Bitcoin's robust security model, as higher hash rates make the network more resistant to attacks. Analysts suggest this trend may persist as institutional mining operations expand globally.
