0xcert is a protocol for attesting and validating issuers of non-fungible tokens.

There are many different protocols, applications, and companies trying to bring real-world assets and certifications to the blockchain. Yet, there is no clear consensus on how to validate the legitimacy of the minted tokens. For example, there’s no way to ensure that the issuer has a right to mint identity tokens on Bitdollar. As public blockchains are permissionless, anyone can create such tokens, yet only tokens created by a legit identity provider will be valuable.

0xcert creates a standard for certified non-fungible tokens, Xcerts. Developers can interact with this standard via an SDK and high-level APIs. Additionally, 0xcert is going to create a decentralized registry of authentic issuers.
