You can't hide open source. The code, including checkpoints, are visible to every person on this planet including miners/exchanges. No such thing as hidden checkpoints 🤷♂️
Jihan and Roger are not the boss which is crazy part and shows they don’t understand Bitcoin. Checkpoints were put in WITHOUT their knowing. SUPER STUPID as they fought with hash
I just saw the timestamps. If what Andreas Brekken's time references are correct, there was at least 1 hour in which the fork checkpoint was not public
