What is Sismo?

Sismo is a modular Attestations Protocol focused on decentralization, privacy and usability.
The protocol is live on Polygon (contracts) and you can mint your first ZK Badges on our alpha product.
Using Sismo, users can generate a wide range of attestations, such as "Donated to Gitcoin grants", "Voted 2 times in the ENS DAO" or "Sent 100+ transactions on Ethereum".
With these attestations, they can gain access to premium features within gated services, or prove their reputation in apps and protocols consuming said attestations.
Attestations are easily accessible via Non-Transferable Token (ERC1155) representations known as Badges.
For each attestation they generate, a user will also receive the associated Badge.
Sismo Attestations are especially useful for:
Web2/web3 gated services
Reputations systems
Decentralized Identity curation
ZK Attestations
A strong focus of Sismo is on ZK Attestations, which do not reveal anything about how they are created. The generation process of a ZK attestation relies on zero-knowledge proofs (ZKP) and ensures user and data privacy.
Modular and Interoperable
The Sismo protocol is modular with multiple types of attestations co-existing; these are generated by various Attesters (smart contracts) that make different tradeoffs on privacy, decentralization and/or scalability.  
Sismo's end goal is to enable diverse and interoperable attestations that can be meshed together in creative ways, and facilitate real innovation on authentication and reputation systems. 
Anyone can propose new data to be attested or build la new attester with a novel logic for attesting data.

Are you a community looking to reward your most important members, a project in need of a reliable reputation system or a service that wants to gate some of its features?
Let us show you how do this with an open-source, decentralized, privacy-preserving protocol!

Sismo Genesis Team
Sismo Genesis Team is the core engineering team in charge of developing software to support Sismo's mission and roadmap. 
It has 3 main goals:
Kickstart the Sismo Protocol
Develop and maintain new attesters
Build products and tools to improve the usability of attestations
Sismo Genesis Team are the initial core maintainers of the Sismo Protocol, while its development and governance is to be progressively handed to Sismo DAO.
Sismo DAO
Sismo DAO is a protocol DAO launched in October 2021 to progressively oversee and manage the development and maintenance of Sismo Protocol. It started as a social DAO, gathering curated generations of members sharing similar interests about privacy, reputation, identity and zero-knowledge proofs. 
It is currently in charge of the allocation of Sismo DAO treasury and will move step by step towards an administrative role over Sismo Attestations Protocol.
