Telling real from fake. Proving a document is authentic. Forever.
TrustIDX anchors your documents' digital fingerprint on a public blockchain. Every certified document becomes verifiable by anyone, at any time, with no mandatory middleman.
No crypto account. No technical knowledge required.
In the AI era, any document can be imitated, forged or backdated.
Contracts, diplomas, certificates, reports, invoices, but also photos, videos or audio files: the tools to produce convincing fakes have never been this accessible. The question is no longer whether a document looks genuine, but whether you can prove it. TrustIDX provides that proof.
A simple, public, permanent proof.
The fingerprint
Every file gets a unique cryptographic fingerprint: Word or Excel document, PDF, image, video, audio… any digital file, as is, with no conversion whatsoever. The file itself never leaves your organisation: only its fingerprint is used.
The anchoring
That fingerprint is recorded, timestamped, on Base, a public layer-2 blockchain secured by Ethereum. Once recorded, it cannot be tampered with.
The verification
Anyone can verify, freely and forever, that a document is authentic, dated, and genuinely comes from the organisation that issued it.
Any digital file. No conversion. No limits.
Your data stays with you. Always.
Only your document's fingerprint is recorded on the blockchain. A fingerprint reveals nothing: it is unreadable and cannot be reversed. Neither the file, nor its content, nor its metadata ever leaves your organisation.
What is a digital fingerprint?
A fingerprint (or hash) is a unique, fixed-length code computed from your file, much like a human fingerprint. Change a single comma or pixel, and the fingerprint becomes completely different. The document cannot be reconstructed from its fingerprint: the computation only works one way. And in practice, two different files cannot produce the same fingerprint. In short: the fingerprint proves everything about your document, yet reveals nothing of it.
The fingerprint is enough
No access to the source file is needed to certify it: holding its fingerprint is enough, along with any associated metadata. The one who certifies is not necessarily the one who holds the document.
Nothing readable on the blockchain
Only the fingerprint is publicly recorded. It reveals nothing about the content: the document, its text or its images cannot be deduced from it.
Your metadata belongs to you
You alone decide which metadata to associate with a document. It stays with you and is never published.
One single prerequisite: your domain name.
Your domain is your identity. It is what proves the provenance of every certified document, publicly and unambiguously. If your organisation owns and controls a domain name, it is ready to certify.
- Nothing to install, nothing to deploy
- No hardware, no infrastructure
- No blockchain expertise required
- No access to the files needed: their fingerprint (hash) is enough
The strength of blockchain. Without the speculation.
TrustIDX is not a crypto project. We use the blockchain for what it does best: a public, neutral, tamper-proof, permanent ledger. And for nothing else.
No token
No TrustIDX token, no currency to buy, nothing to trade.
No wallet
No wallet to install, no crypto knowledge required. Just a service.
No speculation
Nothing to stake, nothing to win, nothing to lose. Only the proof matters.
The blockchain as a registry of trust. That's all. And that's a lot.
