Contract on explorer

How this is verified

Certificates: nft_tokens_for_owner on diploma.retr0school.testnet (testnet (beta)), read now. They are soulbound (non-transferable) and the contract only mints after checking the exam grader's ed25519 signature.
Shipped contract: must be the account itself or its sub-account (only the parent can create one) with Wasm deployed. The code hash is re-checked live on every view. The link is a server-signed record, so the certificate contract didn't need to change.
