'Time-Lock Puzzles' is a new term for me.. It's always in the name. Then you know what to look for on Google.
The idea seems that you can lock data up in such a way that it can be decrypted ONLY after a certain amount of sequential tasks are performed. And this task CANNOT be run in parallel. Like it.. Seems the inverse of what i was looking for, but definitely in the same ball park.. Thanks
Could it be used as some form of Hash Function ? Or as a sort of POW system..
I am searching for more info now.. {..starts sucking the interweb..}
