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.

What do you want to encrypt? Does it have to be stored on chain? We could technically do something like this with Darkblock w/ the encrypted files stored on Arweave & immutably attached to an NFT. They could become unlockable at a certain block height. Though we don’t currently support the “anyone can decrypt” sc

I basically would like the equivalent of people sha256’ing their predictions and tweeting about it, but where the prediction is guaranteed to get revealed at block X and the predictor can’t withhold data/censor.

What needs to be on chain is enough data for anyone to “decrypt” the prediction when block X is reached.

this would cool for voting too

I casted a vote and here it is, but you can't know how i voted until block X

We could use a modified version of the rental tool we're building but use block height as trigger for content to be decryptable.

For context, Darkblock is an encryption protocol for web3-native distribution & monetization of multimedia content & other digital goods using NFTs w/ decentralized unlockable assets.

Our rental tool is to help creators monetize...

In this case, each event being predicted (ie, football game, election) would be an NFT collection. Creator uses our “owner-generated content” endpoint (coming soon) so holders can attach encrypted predictions to collection, which can be unlocked after chosen block he

@tim I still don’t get how Farcaster treats replies. Just noticed that because I replied to @slobo.eth’s cast & then my own, I don’t think you were tagged & so wouldn’t have been notified. Wanted to make sure you saw my casts as I was actually replying to you.

Then again, if you saw them but moved on, no problem!

Digital content & other assets that are contained within what we call darkblocks are stored on Arweave. Our protocol uses proxy re-encryption. Here's a diagram: https://i.imgur.com/GIgahcb.jpg
