This paper shows how to build a special type of commitment scheme called a "timed commitment" using only a "time-lock puzzle" as a building block. Timed commitments are like digital safes that automatically open after a set amount of time, ensuring that a secret is eventually revealed. This is a big deal because it allows us to build these timed commitments from a wider range of assumptions, including some that are believed to be secure against quantum computers. The post-quantum security claim hinges on the security of a specific TLP construction.
