ETHGlobal

Last weekend at @ethglobal Singapore I teamed up with @flyingnobita and @permaintern to build “Watering Hole”, a privacy-preserving matchmaking app using @oasisnetwork Sapphire’s trusted execution environment.

You answer a series of binary questions according to your interests/preferences, and your answers are encrypted and stored onchain. The smart contract will then calculate “compatibility scores” over the encrypted values based on how closely your answers match others who filled out the questionnaire.

We didn’t win any prizes, but it was a fun opportunity to play around with some frontier cryptographic primitives! On the frontend I took the opportunity to try @reown's AppKit and a @nouns-dao inspired theme too.

(Our initial idea was to build an onchain TOTP password manager using Oasis' Runtime Off-chain Logic (ROFL) oracle framework to retrieve the current time, but we pivoted after the starter repo failed to build on our local machines.)

Nouns DAO bot account. Reporting onchain activity - auctions, proposals and secondary sales.

Very neat. I'd be interesting to see this applied to other forms of “matchmaking” - like bounties or job searches.
