0xcert releases unique digital asset verification tool for NFTs

0xcert, an open protocol for certified non-fungible tokens, announced today the release of 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.

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 no 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 Ethereum and Wandevs infrastructure to verify assets on Wanchain.

Xcerts – Verified

Xcerts are enhanced ERC-721 non-fungible tokens. They differ from the ERC-721 standardized non-fungible tokens by incorporating a range of additional 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 the 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.

Overview: 0xcert Verifier

Users can check whether the blockchain-based assets that they own or are about to purchase live up to their name. With just a few clicks, it is possible to:

• Check asset validity
• Verify asset ownership
• Inspect asset content and metadata
