It’s the most wonderful time of the year and the 0xcert team wishes everyone a happy and joyful Christmas. As a special and non-fungible gift to our community, we decided to release a crucial piece of the open-source 0xcert ecosystem a bit earlier than planned: the 0xcert Verifier. It provides an elegant way of verifying the validity and content of any digital asset issued with the 0xcert infrastructure. Verifying unique digital assets is an important part of many use cases, so the 0xcert Verifier will no doubt come in handy. Go ahead and play around with it, but more importantly, make sure to enjoy this magical Christmas time!

About the 0xcert Verifier

To help you verify the validity and the content of your digital asset in the form of Xcert on the blockchain, we've created the 0xcert Verifier, a simple and straightforward online tool that checks your unique digital asset in seconds.

Verify your digital assets

Powered by the 0xcert Framework

The 0xcert Verifier runs on a set of rules and mechanisms integrated within the 0xcert Framework for building dapps. It allows for easy verification of digital Xcert assets for their owners, even those with zero coding or blockchain knowledge. The 0xcert Verifier runs asset validation by checking the asset evidence and detailed metadata, among others, and provides a clear list of true or false results to checked inputs.

The source code of the Verifier is published publicly on GitHub, and uses the Infura infrastructure to verify Xcert assets on the Ethereum blockchain and Wandevs infrastructure to verify assets on the Wanchain network.

Xcerts - verified

Xcerts are enhanced ERC-721 non-fungible tokens. They differ from the ERC-721 standardized non-fungible tokens by incorporating a whole range of additional asset features apart from the asset ID (ERC-721), namely:

Asset schema ID: an ID representing the JSON-Schema data definition

Asset evidence: a set of asset proofs describing multi-level JSON objects that verify the existence of arbitrary data in the original data object within the asset

Asset imprint: cryptographic representation of original data object

Selected asset metadata check: enables a filtered check of specific metadata keys, both private and public, that are represented by the digital imprint of the asset on the blockchain

Going a few steps further from the structure of the ERC-721 standardized non-fungible token, the Xcert allows for a detailed check and validation of specific data that define the uniqueness of a blockchain-based asset. Thanks to the schema ID, Xcerts use asset type metadata schemas that define only a single data type, e.g., a car or educational degree, etc.

Check your unique Xcert asset with the 0xcert Verifier

Make an informed decision before purchasing a blockchain-based asset or provide solid evidence to your clients, showing your unique digital asset lives up to its name.

Verify your digital assets

This tool allows you to check assets without having to code the verification process yourself, saving you some time, money and hopefully some nerves as well. By releasing the 0xcert Verifier to our community, we simply want to say: Thank you.

Merry Christmas to everyone!
