H3aven - Gata (Governance for Data)

Context: H3aven.com, the leading B2B-Baas of LATAM serves companies by certificating contract and process workflows via corporate blockchain consensus. In ETH Tokyo our goal is to decentralize data storage, so we present GATA: A Data Governance Framework based on Tokenized Organizational Roles.

User stories: -> Only a NFT holder is capable of accessing encrypted data. -> All profiles with the same role can access the same data. -> Whenever an user is removed of its role, access to specific data is also atomically removed.

Unprecedented Value to Society: Solution to credential double-spending: It is much more dangerous to share a private-key than to share recoverable credentials (Netflix password).

Solution to the corporate data kidnapping problem (Ransomware) by distributing data silos by company roles with complete data redundancy.

H3AVEN - GATA uses SAFE'S account abstraction to streamline WEB2 access to WEB3 as well an integration with Gellato a paymaster to outsource fees away from users.

For the decentralized storage it uses Filecoin integrated via Lighthouse. All data is encrypted and only accessed if the user is a holder of a given NFT.

The best hacker merit we had was to make a mass adoption plataform with easy access and granular data control compatible with the most common token standard in web3.
