Securely anchor, verify, and manage your digital evidence with the power of blockchain technology. Immutable, transparent, and trustworthy.
Your Files Are Lying To You
In the age of AI and deepfakes, a standard file is no longer proof of anything. It is just a container of distinct pixels, easily manipulated and impossible to trust.
Time is Malleable
Metadata dates can be edited with a simple command line. A timestamp on a standard file proves nothing about when it was actually created.
Content is Fluid
A single flipped bit can change a contract, a photo, or a log file. Without a cryptographic seal, "original" is just a label you hope is true.
Custody is Broken
If your evidence lives on a centralized server, the admin owns the truth. Deletion, modification, and access trails are all just database entries.
The Standard
Undetectable Edits
Files can be altered without leaving a trace. Hex editors, Photoshop, and deepfakes make seeing believing difficult.
Platform Dependency
"Proof" relies on Google or Amazon not losing your log. If the platform goes down, your truth disappears.
Revocable History
Admins can wipe logs. History is rewritten by those with root access.
Evidence Vault
Cryptographic Seal
Every file is hashed. Even a 1-bit change breaks the seal instantly, flagging manipulation.
Mathematical Trust
Verification happens via math, not brand trust. Verify proof independently, offline, forever.
Immutable Ledger
Anchored on the blockchain. Once recorded, history literally cannot be edited or deleted.
A continuous cryptographic journey.
Every step seals the evidence tighter, turning a simple file into undeniable proof.
Ingest
Secure upload via encrypted tunnel. File never leaves your custody if using client-side hashing.
Fingerprint
SHA-256 hash generation. This unique digital signature is sensitive to even a single bit change.
Anchor
Hash is batched and permanently anchored to the public blockchain ledger.
Verify
Anyone with the file can now verify its existence, integrity, and timestamp instantly.
Built for Uncompromising Truth
A complete suite of tools designed to generate, preserve, and prove the integrity of digital assets.
Tamper-Proof Sealing
The moment a file is uploaded, it is mathematically sealed. Any modification, no matter how small, invalidates the record instantly.
Immutable Timestamping
Anchored to the blockchain. You can't fake time. We provide mathematical proof that a file existed at a specific moment.
Universal Verification
No proprietary software needed. Our open-standard proofs can be verified independently, offline, and by any third party.
Chain of Custody
Granular audit logs for every action. Know exactly who viewed, downloaded, or shared evidence, and when.
Privacy by Design
Your raw files remain private. We only anchor the cryptographic fingerprint (hash) to the public ledger.
Sovereign Ownership
You own your proof. It's not locked in our platform. Download your proof bundle and keep it forever.
Powered by Unbreakable Infrastructure
We don't just store your files. We anchor them to the most secure decentralized networks in the world.
Blockchain Anchor
We use Ethereum & Polygon smart contracts to record the cryptographic hash of your evidence. This creates a global, censorship-resistant witness that cannot be bribed or shut down.
Smart Logic
Our open-source smart contracts govern the logic of verification. They execute automatically without human intervention, ensuring that the rules of evidence can never be bent for anyone.
IPFS Storage
We utilize the InterPlanetary File System (IPFS) for distributed storage. Your data isn't on one fragile server—it's sharded and replicated across a global mesh network.
