proof of crosswork:

without an online verifier (server or a blockchain), is there a solution for “i signed this no earlier than X in a way you can validate”?

any time someone finishes the MW with a crappy connection, it adds time.

would be cool to solve this but smells intractable

Could maybe use a new latest block or txn hash onchain that isn’t knowable before X time. Could hash it with the solution if you want to make sure they know the solution at the time

Looking for work.

requires access to the blockchain right? also could always pick an earlier block to say solve time was faster: think we want to guard in the other direction
