Is there a way to encrypt something on Ethereum and âforceâ decryption at a certain block? Idea is to sidestep not revealing the data. Itâs fine if âas of block X, anyone can decryptâ, not just the original sender.

Timelock cryptography. Not the timelock contract pattern that OpenZeppelin has but something like an RSA or IQC style timelock puzzle. Itâd be just as decryptable off-chain as it would on-chain, but that would be the way to do it. Youâd basically set the parameters such that itâs _roughly_ the right height, err h

Would you basically encrypt something, post your time lock parameters on chain, and then have people run the puzzle off chain to decrypt?

Yeah, or construct the seed for encryption on chain via some kind of MPC ceremony a la REDSHIFT to receive the data to encrypt if you need it to be fed in from some source that is not a human

No prob, if youâre curious to hear more about timelock cryptography, Iâm giving a talk about it this Wednesday at Solution1: https://www.youtube.com/channel/UCVrf4mR6fyMz24WImpyxDWw/streams it will be titled âThis Message will Self-Construct inâŚâ
