Record your document hash on the blockchain

The hash is a sha256 hash of the content of your document. The filename is not part of the calculation.


What is proveit?

Today, in order to prove the existence of a document at a specific point in time you would be required to go to a notary, who would sign and stamp your document, and then submit it to a public registry. To prove the submission of that document you would have to return to a notary and request a letter attesting to the document’s existence in a particular registry.

Proof of Existence solves the necessity for 3rd party notarization and attestation by providing a trustless, digital interface in order to prove that a document existed in a certain state at a specific time.

Between 800,000 to 900,000 insurance policies were sold to Jewish victims of the Holocaust yet only 47,353 insurance policies were paid out. The value of unpaid Holocaust-era insurance policies ranges from $17 billion to $200 billion. When it comes to shares of corporations, in France alone, the shares of over 45,000 Jewish companies were expropriated and handed over to non-Jewish persons. Other types of shares involving public corporations held in safety deposit boxes were confiscated and transferred to German agencies by collaborating banks in the EU. Very few of these sorts of claims have obtained legal closure.

There is an urgency to resolve these claims. The victims of the holocaust, now in the later stages of life, control the last vestiges of the documentary evidence vital to the restitution of looted assets. Such evidence is extremely fragile.

Similar to a copyright interest that can be registered to prove its existence, financial assets can and should be capable of third party registration to protect them from theft, misappropriation or other hazards of humanity. We focused on insurance policies and shares of corporations because each are financial instruments that were externally recorded by third parties and have product identity numbers.

ProveIt works with accredited professional notaries, institutional partners and jurisdictional legislatures to record and prove the existence, substance, and property of a claim.

Record evidence

Simple, intuitive interface to record evidence. Very low transaction cost guarantees easy access to everyone.

Immutable ledger

Fingerprints (hash) of documents get stored on the public Blockchain. We store data for future generations. so redundancy of multiple Blockchains is our key to maximise the integrity of our proof system.

people

Transparent independent validation

Easily prove the authenticity of your documents and enable third parties to verify the information independently.

mail

Privacy

Your document fingerprints don’t allow recreation of your original document content. Which data you want to publish is fully in your hands.

How does it work?

fingerprint

Record

We calculate a fingerprint (hash) of your document. This fingerprint will be added to our processing queue. Optionally we will store your document as well as its meta data on a cloud storage.

Write

On a regular basis we group multiple fingerprints into a merkle tree. The root hash of that tree will then be written to the Metaverse Blockchain.

Prove

In order to prove the timestamp of your document independently we will provide you with the proof path through the merkle tree as well as the Blockchain transaction as a proof of record.
