⚡ Block #954,671
⛏️ Solo Miner Packs Block 954671 to the Brim
June 21, 2026 at 07:47 AM UTC
Block 954671 was mined by an unknown solo miner — someone operating outside any major mining pool — which is a rare sight in today's highly competitive mining landscape. They filled the block almost entirely to its weight limit with 6,881 transactions, making it one of the busiest blocks around. Curiously, the total fees recorded are 0.00 BTC, which may reflect a data quirk worth watching.
