Is there a way to encrypt something on Ethereum and “force” decryption at a certain block? Idea is to sidestep not revealing the data. It’s fine if “as of block X, anyone can decrypt”, not just the original sender.

Pretty sure it’s impossible. Interested to know if such a thing is possible on any of today’s platforms.

I think if it’s impossible it’s more of an information theory issue: there would need to be some privately knowable information that becomes public knowledge at block X, and when you frame it what way it seems impossible given a blockchain’s design.
