The Logion public certificate

The Logion Online Certificate stands as a solid embodiment of the Proof of Law concept. It functions as a secure online certificate based on zero-knowledge proof (ZKP) architecture, with restricted delivery of digital assets and files. In essence, the certificate enhances safe digital ownership and bridges the gap between real-world assets (digital, physical, or financial) and their digital representations.

Logion does this by immutably binding the certificate to the minted token, regardless of the blockchain of issuance used, providing a layer of transparency and trust for all parties involved.

Logion provides smart contract developers with ways to engrave the Logion certificate credentials within the token data:

One of the most distinguishing features of the Logion Online Certificate is its utilization of zero-knowledge proofs. By providing an on-chain proof of existence without revealing content, it safeguards the privacy of the token holders while still validating the existence and ownership of the digital assets.

In a context where verification of authenticity and legitimacy of ownership is paramount, such as in the art NFT market, the Logion Online Certificate also serves to clarify Intellectual Property rights, ensuring the rights of creators and buyers are rightfully protected.

Moreover, this online certificate integrates token-gated access, meaning that delivery of assets and documents is restricted to the verified token owner following their authentication (e.g., via MetaMask, Ledger, or Crossmint). This protocol guarantees that only the legitimate owner can access the underlying assets, maintaining the exclusivity and value of the token.

Lastly, the Logion Online Certificate offers tools to verify assets and documents' authenticity, providing a robust shield against fraud and counterfeit items. The integration of these tools adds another layer of confidence for token holders and users in the ecosystem, reinforcing the idea that what they own is genuine and protected.

In summary, the Logion Online Certificate transforms the concept of digital ownership, bringing an unprecedented level of legal and economic certification to the digital economy. It takes what is best about blockchain technology - immutability and transparency - and marries it with the legal robustness required for real-world assets and intellectual property rights.

The LOC’s public certificate may be displayed by the web application given the LOC’s ID. This view requires no authentication and is publicly available. The public certificate is essentially a user-friendly view of the data written on-chain.

A collection item has its own certificate which exposes the LOC public view combined with the collection item’s public view. The collection item certificate enables restricted delivery by letting token owners authenticate and therefore be able to download files with restricted delivery enabled.

The certificate of a void LOC has a different appearance making it clear that the currently viewed LOC is void. If a LOC has been voided and replaced, the certificate automatically displays the replacing LOC (but keeps the possibility for the user to follow a link in order to view the voided LOC’s certificate). If there is a chain of voided LOCs (e.g. A voided and replaced by B, in turn voided and replaced by C), the certificate will display the certificate of the last LOC (C in previous example).
