Ironically I was blocked on r/bitcoin & bitcointalk many years ago because of unenjoyable questions and today by 1L9D9Zv9BFqTQScFJzz8rXiUjnmnGxRBvk. Keep up your good work!
"When a node receives a block, it checks the signatures of every trx in it against previous trxs in blocks. Blocks can only contain trxs that depend on valid trxs in previous blocks or the same block."
i just watched CSW's Coingeek talk and his Exeter talk. i don't know if he's Satoshi, but he's either one of the most intelligent people in this space, or no one else is intelligent enough to debunk him.
It does not matter but he is promoting BCH, that's what matters.
You can play chess. It’s fairly slow though, since chess takes a lot of moves, so you end up waiting until the other person is online many times. A fast game like blackjack might work.
