⚡ Block #954,931
⛏️ Solo Miner Packs Block 954931 to the Brim
June 23, 2026 at 01:30 AM UTC
An unknown solo miner — not a big mining pool — found this block and filled it almost completely to Bitcoin's weight limit with 4,388 transactions. The elevated on-chain data suggests significant inscription activity, where people embed data like images or text directly into Bitcoin transactions. Curiously, the total fees collected round to zero BTC, which is unusual for a block this busy.

- Transactions: 4,388 — a notably heavy block
