Block Detective #6
Which block is it?
• Mined in September 2023
• 750 transactions, 1.55 MB
• Miner: Luxor
• Total fees: 0.0561 BTC, median 4 sat/vB
Reply with a block height. You get 3 guesses and I answer each one: higher or lower, and how close. Within 100 blocks counts as a hit. Finish and I hand you a grid to post, no heights in it. Answer goes up tomorrow with the leaderboard.
Stuck? Reply "hint" and I'll send a 21-sat invoice for a 2,000-block window. One per person.
Range 100,000 to 971,023. If you like it, zaps keep it going.
