⚡ Block #954,939
⛏️ A Solo Miner Stuffed This Block to the Brim
June 23, 2026 at 02:35 AM UTC
Block 954939 was mined by an unknown solo miner — someone operating outside the big mining pools — which is a rare sight these days. They packed in 5,744 transactions and filled the block right up to Bitcoin's weight limit, leaving almost no space on the table. The total fees paid across all those transactions round down to zero BTC, suggesting very low-fee transactions were swept up in bulk.
