0xcert is an open source permissionless protocol for non-fungible tokens on the blockchain. These tokens are stored in cryptographic wallets and are owned by users. In addition to common functions for transferring and managing standard non-fungible tokens, the 0xcert protocol provides another layer of conventions for creating certified non-fungible tokens for unique assets. These tokens are called Xcerts and are created through a custom minting process. Xcerts represent opinionated non-fungible tokens, which also hold an imprint of an asset. With 0xcert protocol, we can validate a proof of existence, authenticity and ownership of these digital assets without third-party involvement. 0xcert is a framework with a set of on-chain and off-chain rules for managing Xcerts and other standard non-fungible tokens. Our mission is to equip application developers with a secure blockchain agnostic platform, powerful tools and community embraced conventions for managing non-fungible tokens. 0xcert is a pluggable settlement with an advanced integration layer for different dapps and relay applications. This enables developers to focus on the application layer and quickly build applications for issuing university certificates, KYC applications, applications for loyalty programs, warranties, badges, credits or even a decentralized non-fungible exchange. A key role in the 0xcert infrastructure is played by the ZXC utility tokens. These are fungible tokens that are compliant with Ethereum’s ERC-20 standard. The ZXC token might be utilized to support dapps built on top of the 0xcert protocol with minimum possible fees. Since 0xcert is an open source project that strives to be community driven, a decentralized governance model could be introduced as well. We recognize that one of the fundamental problems in the blockchain space may become the authenticity of issuers in the future. A decentralized issuer verification registry may be an acceptable and self-sustaining solution to the problem. The community would have an option to either verify or reject new Xcert issuers through a staking and rewarding mechanism based on the ZXC token. Furthermore, 0xcert is also building out a whole ecosystem of parties involved in the non-fungible space, as well as specific application developers, companies from various verticals, researchers, organisations and communities. Planned growth activities will not only positively impact and extend further adoption of technologies developed by 0xcert, but also expand the scientific horizon of non-fungible tokens in general.


The vision of 0xcert is to provide an open protocol for standardized and certified non-fungible tokens to a wider tech audience. With 0xcert, you can build on top of the non-fungible token standard, employing a complete toolset, development framework, and a set of conventions for various use cases. This results in shorter development time, lower risk and cuts cost associated with developing blockchain solutions. A wide range of decentralized applications and business models can be supported, giving companies the power to fully utilize the potential of blockchain technology.
