This has already been invented (Drand). Unlike this project, it also does not say “even we can’t decrypt timelocked files”
(they can)

It’s also a multiparty protocol so it is available even if one party fails, or is malicious.

There is a production instance backed by many different companies and organizations too

River CEO leishman (npub139n…kwf4) built a time-lock encryption oracle as a side project.

Upload a file, choose when it should be unlockable, and the system encrypts it with an RSA key that only becomes available at the specified time. Anyone with the encrypted file can decrypt it in their browser once the key is released.

It publishes RSA keys for each minute over the next 30 days, then releases the corresponding private key at the top of each new minute. Works in the browser for humans and via curl and openssl for developers and AI agents.

Use cases: delayed data access, embargoes, sending messages or files to the future, or anything else that needs a trustless time delay.
