Like all data on Ceramic, assertions and claims can only be created and controlled by one account using a familiar “Sign in With Ethereum” authentication flow.
Users can make assertions about other entities, data, or about themselves. This data class is often referred to as attestations, and encompasses technical standards like W3C Verifiable Credentials.
Frameworks that facilitate claims include features such as tamper-evident cryptographic signatures, public schema registries, presentation and validation formats, transparent provenance, and portability. This is because the credibility of a claim should only hinge on the reputation of the entity making it, not on the framework that was used to create it.
As a shared data network designed specifically for verifiable data at scale, Ceramic is designed for verifiable data at scale, providing the common characteristics of verifiable claims out-of-the-box, from cryptographically signed data events, to gold-standard data provenance and lineage specifications.
Claims, attestations, and assertions are integral to establishing trust and credibility in a digital world. Ceramic not only provides a mechanism to create, verify, and validate claims across flexible scenarios, but makes it possible for developers to build composable applications on user-owned assertions that aggregate to form reputation, identity, and trust.
Masca is a MetaMask Snap that allows users to save Verifiable Credentials to Ceramic.
Gitcoin Passport is a sybil resistance protocol and identity aggregation dApp built on the Ceramic Network.
VESS Resume is a self-sovereign credential resume built on the Ceramic Network.
Orbis is a composable ecosystem of social experiences built on Ceramic and supports the issuing, storing, and validating of credentials.
Intuition is a knowledge-sharing ecosystem that enables the creation of reputation and trust across the digital realm using attestations.
CharmVerse uses attestations to make assertions about users who have applied for grants, all the way through grant acceptance and receipt.
Snickerdoodle, a privacy-preserving digital marketing platform, created Zero Knowledge (ZK) proofs as a computed result of attested user engagement data.
Oamo is a decentralized data broker that allows users to generate credentials matching their on and off-chain behaviors that are eventually stored in ComposeDB.
Pact.Social can be thought of as a decentralized Change.org, allowing users to promote causes using Verifiable Credentials.
At the core of W3C standards are the features they unlock, not only for the users themselves but for the developers integrating them into their applications.
A deeper dive into the technical architecture, considerations, and trade-offs that enable ComposeDB and Ceramic to support data lineage and provenance.
