I’ll Show You Without Telling You: EUDI Wallet, Zero-Knowledge Proofs, and Verifiable Delegations

Today, many digital services still work like this: to verify something, they ask for everything—full identity documents, personal data, copies that end up stored and circulating, and trust that someone will handle them properly.

With the EUDI Wallet and Zero-Knowledge Proofs, a different model becomes possible: proving a requirement without exposing the data that proves it, and using those proofs inside real-world processes.

In this demo, we start from a concrete use case: identifying yourself, purchasing a discounted ticket for an event, storing it in your wallet, and presenting it at the entrance. Then we take it a step further: delegating the operation to an agent, but with precise, verifiable, and revocable rules.

Not “the agent can do whatever it wants,” but “the agent can only do this specific action, within these limits, using only the necessary proofs.”

Digital identity, verifiable credentials, and automation thus become parts of the same continuous flow.
