Miners do check the blockchain to stay healthy and the longest chain is the chain we are going with

And I do think it's an AI, however, if I am wrong - the voice is impeccable for presentations!
Great job, OP.
That's why bitcoin transactions have third party involved because the transactions won't go through if there's no one mining the block and if no one is mining the block then the transactions won't be included in the blockchain and would only stay in the mempool. I wouldn't mind if OP will use AI as long as the voice is clear and said correctly then it doesn't matter if it's AI or not. I also like the name that OP use which is hideyourkeys which is related to not your keys not your coins.
