3nable — WINNER

3nable allows users to sign into their crypto accounts from any computer, without having their private keys on hand. After an initial setup through the 3nable site, users are able to trigger a one-use code, which then uses a secret contract on Enigma to sign messages and transactions.

We selected 3nable as our winner because it was a generalizable service that could have network effects with other projects in the ecosystem, and they also ended the hackathon with a working prototype. We thought it was creative and well-executed. For example, this type of setup could be adapted to a product with similar architecture, described by the Tornado Cash team — a way to store the note associated with a zero knowledge proof in an Enigma secret contract.

Next steps for a project like this would include de-risking the private key storage, possibly with a “travelers check” style account, where users only keep small amounts of crypto at a time in this “3nable” account.

Trippple Blind

Trippple Blind enables participating researchers and other parties to get information about double-blind medical studies without exposing sensitive data. Queries about demographics and outcomes are executed in secret contracts, while data is submitted via the study organizers. We were also very impressed by this project, which resulted in a working prototype complete with sample queries.

SkipID

The SkipID team was inspired by a personal experience with car dealerships, where a customer needs to hand over her ID. This ID is then taken into another room, where the customer can’t even see what’s being done with it. The dealership only needs to verify that the customer is over 21 and has a valid license. There are many other situations like this — for example, gaining entrance to a hackathon!

The SkipID demo allows a user to submit encrypted data to a smart contract which checks if certain parameters (i.e., age > 21) are met. This project is exciting because it relates to the work the Decentralized Identity Foundation is doing on decentralized identifiers and is very complementary to the work being done by decentralized identity solutions like 3box. A next step for a project like this would be to present a method for verifying authentic data on the input side — such as signed messages from a trusted authority.

AnonHero

The Enigma-related concept in AnonHero is that you can filter media from an event along demographic lines (i.e., images uploaded by people under 30) without revealing personally identifying information. AnonHero won jury prizes at ETHBoston for this concept!
