This tracker monitors for Bitcoin blocks where the reward was paid to a single address (minus any fee) rather than being split among participants, using publicly available solo mining software like Solo CK and Public Pool. I've also included the hashrate marketplace Braiins Solo, since rewards are paid out to a single buyer. Currently the feed goes back to January 2023 (block height ~772000).
