⛏️ NiceHash Packs Block 961227 to the Brim

45/ 100

August 6, 2026 at 01:13 AM UTC

Block 961227, mined by NiceHash, squeezed in 4,121 transactions while filling right up to Bitcoin's block weight limit — an efficient use of space. Despite all that activity, total fees paid were unusually low at just 0.027 BTC, meaning senders got a bargain. NiceHash also left a readable message in the coinbase (the special first transaction every miner writes to claim their reward).
