Why not store user data only in the database instead of encrypting it into the blockchain?

Because EMOZ is built on the principle of decentralized, independently verifiable proof, unlike traditional centralized systems that rely entirely on a company’s servers and continued operation.

If your data were stored only in EMOZ’s internal database, your certificate would become unverifiable if:

  • EMOZ experiences downtime or maintenance,

  • Our servers are compromised,

  • Or EMOZ shuts down permanently.

That’s the limitation of centralization: the proof depends on trusting that EMOZ remains online.

Instead, EMOZ stores the encrypted metadata directly on the blockchain, along with the file’s SHA-256 fingerprint. This ensures:

  • Decentralization: the certificate exists on a public blockchain, not on EMOZ’s infrastructure.

  • Independence: authorship can be proven using only the original file, the transaction ID, and the seed contained in your PDF certificate.

  • Persistence: the certificate is valid and verifiable forever, with or without EMOZ.

EMOZ is simply the facilitator. The proof lives on-chain, and doesn’t depend on us to remain usable.

Of course, for your convenience, EMOZ does offer centralized features like:

  • Viewing your certificate history in your account,

  • Re-downloading any certificate,

  • Accessing help and verification tools via our web interface.

But those services are optional. The core proof of authorship remains self-contained, decentralized, and future-proof by design.
