If you are interested in a time-lock implementation you can use today, here is one I made some 5 years ago and still using: https://github.com/rayanamal/timelock https://github.com/rayanamal/timelock - Can time-lock (encrypt) in negligible time (almost instantaneosly) - Non-parallelizable sequential algorithm - Decrypts in constant CPU cycles (meaning CPU with 2x faster clock will decrypt 2x faster) It can only time-lock numeric data though. It's enough for me, I'm using it to encrypt PINs and root passwords for the Screen Time restriction setups of my various devices (iPhone, Linux PC). It allows me to have unbypassable restrictions while also not having to trust a friend/relative. This concept is known as a commitment device: https://en.wikipedia.org/wiki/Commitment_device https://en.wikipedia.org/wiki/Commitment_device
