Bitcoin 网络挖矿难度两个月来首次下降
Following four consecutive Bitcoin mining difficulty increases, the network’s difficulty dropped for the first time in 68 days, sliding 2.14% at block height 756,000 on Tuesday. The change means it’s currently 2.14% easier to find a bitcoin block reward following the mining difficulty’s all-time high (ATH) that took place on September 13.
Bitcoin Difficulty Slides 2.14%
Bitcoin miners caught a break this week after the network’s mining difficulty slid by 2.14% on Tuesday evening. The difficulty is now 31.36 trillion following the 32.04 trillion ATH recorded on Tuesday, September 13. The network’s difficulty will remain at 31.36 trillion for the next two weeks, as the difficulty is adjusted every 2,016 blocks.
虽然网络的哈希率以每秒 234 exahash (EH/s) 的速度滑行，但统计数据显示，在过去的 2,016 个区块中，平均哈希率为 225.2 EH/s。 根据当前的指标，与当前 BTC prices and electrical costs at $0.07 per kilowatt hour (kWh), roughly 41 SHA256 application-specific integrated circuit (ASIC) bitcoin miners make an estimated profit between $0.12 and $7.95 per day. At $0.12 per kWh, nine ASIC bitcoin miners make an estimated profit between $0.33 and $4.24 per day.
当今最赚钱的 ASIC 矿机前五名包括每秒 19 太哈希 (TH/s) 的比特大陆 Antminer S140 XP、Antminer S19 Pro+ Hyd (198 TH/s)、Microbt Whatsminer M50S (126 TH/s)、 Microbt Whatsminer M50 (114 TH/s) 和 Bitmain Antminer S19 Pro (110 TH/s)。
在过去三天中，矿工发现了 423 个区块，Foundry USA 发现了 108 个区块。 在过去的三天里，Foundry 一直是顶级矿工，占全球哈希率的 25.53% 或 56.53 EH/s。
Foundry is followed by Antpool, F2pool, Binance Pool, and Viabtc respectively. Currently, 11 known mining pools are dedicating hashrate toward the Bitcoin blockchain, representing 98.11% of the global hashrate. Unknown hashrate commands 1.89% of the global hashrate today or 4.19 EH/s used to discover eight blocks out of the 423 found in three days.
同时，在当前的区块时间速度下，下一个难度变化估计会增加大约 1.32%，但这可能会在接下来的 1,957 个区块中发生很大变化。
