Yes. EMOZ certificates are published as public NFTs on the Polygon blockchain (Amoy testnet for test certificates, Mainnet for real ones). Anyone can view:
The existence and timestamp of the NFT.
Its fingerprint (SHA-256 hash) and encrypted metadata.
The public smart contract source code verifying that it is non-transferable and immutable.
This ensures transparency and allows anyone to independently verify your proof of authorship.
