Bitcoin's network recorded one of its busiest individual blocks on November 7, 2026, as mining pool Antpool processed 11,255 transactions in block 974961. The milestone brought Bitcoin within 984 transactions of its longstanding record of 12,239, established in August 2015.
According to Mempool.space blockchain data, block 974961 was mined at 18:24:12 UTC and measured approximately 1.1 megabytes. The block consumed 3,993,844 weight units, representing approximately 99.85% of Bitcoin's four-million-unit capacity.
Despite containing thousands of transactions, miners collected only 0.002405 BTC in fees, alongside the standard 3.125 BTC block subsidy.
Mempool.space developer Mononaut highlighted the achievement on X, stating: 'New #2 record: 11,255. We’re rapidly closing in on the all-time high of 12,239 transactions from block 367853.'
Three days earlier, block 974557 had processed 10,573 transactions, briefly holding second place.
Bitcoin's highest transaction count was recorded on August 1, 2015, when F2pool mined block 367853 containing 12,239 transactions. The block measured approximately 999.96 kilobytes under Bitcoin's former one-megabyte limit.
Its unusually high count resulted partly from compact transactions associated with network stress and unspent transaction output cleanup. Unlike conventional payments, these transactions required minimal space, allowing miners to process thousands within one block.
Bitcoin's SegWit upgrade introduced a four-million-weight-unit framework, allowing transaction capacity to vary according to transaction structure. Recent blocks contain compact transactions associated with the Runes protocol, including UNCOMMON•GOODS minting activity.
According to blockchain data, 10,585 transactions in block 974961 paid less than one satoshi per virtual byte, demonstrating how optimized transactions can increase block counts without generating substantial fees.
Bitcoin processed 913,196 transactions on October 23, 2026, approaching its daily record of 927,010 established in April 2024. However, November's first seven days averaged approximately 534,200 transactions daily, compared with October's 710,400. These numbers show that unusually dense blocks do not necessarily indicate higher overall network demand.
