Crypto that doesn’t suffer from these kinds of failures is boring. It looks like traditional banking with a different API. Exciting maybe for banking nerds, but not so much for anyone else. Ultimately though blockchain ledgers will probably only be long term useful for record keeping between small closed groups of independent entities like banks settling overnight balances between themselves. It’s never going to be entirely algorithmic as there is always the chance of mistake or failure which needs human judgement to correct.
