It is a certificate Cillers issues, published as a TRUE Original document with its own web address. The document's fingerprint is secured on a blockchain. If a single character is changed, the fingerprint no longer matches and the check fails. The first certificate from Cillers was issued in 2024, and the certificates live at true.cillers.com.

How do I check that a certificate from Cillers is genuine?

Drop in the file or paste the link into TRUE Verify at www.trueoriginal.com/verify and see within seconds whether the certificate is genuine and untouched. The check is free and requires no account. It works for every document secured through TRUE, not only certificates from Cillers.

Can a certificate from Cillers be forged?

A copy can be made to look the same. It cannot be made to verify. The check compares the document with the fingerprint written when Cillers issued it, so an altered copy fails.

How do I save and share my certificate?

If you want to gather everything in one place, there is TRUE Wallet, a professional profile where the experience, education and skills you list can be confirmed by documents issued through TRUE.

Is my certificate visible to everyone?

Only if you want it to be. You choose whether the certificate is public, and you can change it at any time.

What happens to the certificate if TRUE disappears?

Every document's fingerprint is anchored on a public blockchain and can be checked independently of TRUE. That is the whole point of anchoring the proof instead of storing it with a company.
