> Figuring out how to make spending your tokens irrevocable is the whole point of PoW/PoS. Maybe I'm missing something... if miners are required to send the to

  No. Did you not read the comment you were responding to?
  • lottin 5y ago
    Yes, I read it. As far as I can see, it talks about 'staking', so it doesn't address what happens when the tokens and 'expended' as opposed to 'staked'.
    • ogogmad 5y ago
      You have two competing chains: Chain 1 and chain 2. On chain 1, you spend a token on a good. On chain 2, you spend no token. You wait for chain 1 to win the race. You then stake on chain 2 to get your money back. If chain 2 then overtakes chain 1, you've executed a double-spend attack. An equivalent attack wouldn't work on a PoW chain. If you do the equivalent of "staking" on chain 2, then you're computing hashes, which is costing real-life resources. In the PoS case, without slashing, staking on chain 2 is free. In fact, this is the rational move to make every time you spend a token; stake on competing chains to get your token back.

        Thanks for explaining (I'm a different someone) There was a PoS mechanism that makes people who cheat lose all their coins? I wonder if it is relevant here ... Aha, that's "slashing" -- the other members in the network would look at the two chains, and notice that you were misbehaving, and add transactions that remove parts of your coins? (They'd add to both chains? Or just the winning one?)

  What stops miners from sending their tokens somewhere, then hard forking from a previous block where they didn’t send them? This has a clear answer in PoW, but not in your scheme
  • lottin 5y ago
    Easy, you put the transaction in the previous block. So the miner can only mine a block if they have already made the expenditure.

      What stops me from doing a hard fork to roll back both blocks?
      • lottin 5y ago
        If you spend more tokens than the tokens that were spent mining the last two blocks you can erase the transactions in those blocks, but isn't that also the case with PoW?
        • seoaeu 5y ago
          You aren’t following. The hard fork lets me double spend the tokens from those blocks.
          • lottin 5y ago
            Indeed, I'm not following your argument.

              Stop asking people to do your homework.
