币安11月10日关闭比特币矿池：算力年内跌约65% 份额已不足全网1%
据 CoinDesk 10 月 15 日报道，加密交易所币安将关闭其 2020 年 4 月推出的比特币矿池。币安本周早些时候宣布，Binance Pool（币安矿池）、矿池储蓄（Pool Savings）、云算力（Cloud Mining）、交易加速器及相关服务将于 11 月 10 日上午 7 时（UTC）关闭，理由是其对产品与服务的持续审查；币安未就这一决定给出财务方面的解释。
矿池算力的大幅缩水先于关闭决定。据 Hashrate Index 数据，币安矿池去年 12 月的算力约为 26 EH/s、占比特币全网约 2.3%；最新表格显示其算力约为 9.2 EH/s、占比不足 1%、排名第 11，降幅约 65%。矿工约有四周时间将机器转至其他矿池；截止时间之后，币安将停止记录用于计算收益的挖矿份额。等待最终结算的用户须在当晚 11 时 59 分（UTC）前完成所需的身份核查，矿池储蓄用户须赎回其头寸。矿池页面将于 11 月 24 日永久下线。币安矿池采用「全额按份额付费」（FPPS）模式，由矿池承担产出低于预期的风险、按工作量向矿工付款。
这并非交易所矿池今年首次退场。CoinDesk 指出，SBI Crypto 已于 7 月 31 日关闭其约占全网算力 2% 的矿池；交易所 OKX 也已于 2024 年 2 月结束矿池服务。报道另提到，币安曾在 2022 年 10 月通过矿池推出5 亿美元的矿工贷款计划，提供利率 5% 至 10%、期限 18 至 24 个月的担保贷款；本次关闭通知未提及该计划，也未披露未偿贷款余额。
Binance to Shut Bitcoin Mining Pool on November 10 After Hashrate Falls About 65% to Under 1% of the Network
Crypto exchange Binance is shutting the bitcoin mining pool it launched in April 2020, with the computing power directed at the service down nearly two-thirds from the end of last year, CoinDesk reported on October 15. The exchange said earlier this week that Binance Pool, Pool Savings, Cloud Mining, its transaction accelerator and related services will close at 7 a.m. UTC on November 10, citing an ongoing review of its products and services. It gave no financial explanation for the decision.
Binance Pool had an estimated 26 exahashes per second, or 2.3% of Bitcoin's network, in December, according to Hashrate Index. Its latest table puts the pool at about 9.2 EH/s, under 1% and ranking 11th — a decline of roughly 65%. Miners have about four weeks to direct their machines elsewhere; after the cutoff, Binance will stop crediting mining shares, the records of work used to calculate payouts. Pool Savings users must redeem their positions, while anyone awaiting a final payout should complete required identity checks by 11:59 p.m. UTC that day. Pool pages will disappear permanently on November 24. The pool used a payout model known as full pay-per-share, or FPPS, paying miners for their work while taking on the risk that the pool found fewer blocks than expected.
Binance follows SBI Crypto, which shut its pool on July 31 after accounting for roughly 2% of Bitcoin's computing power; crypto exchange OKX ended its mining pool services in February 2024. Four years ago, Binance was offering to finance miners' expansion: in October 2022 it announced a $500 million lending program through the pool, offering secured loans for 18 to 24 months at interest rates of 5% to 10%. The closure notice does not address that program or disclose any outstanding loan balance, CoinDesk said.
