What is Proof of Existence (PoE)?

PoE is essentially a Blockchain based notary service to permanently record and subsequently verify that a document or file existed at a certain point in time and is unaltered. Data recorded on a Blockchain is immutable, meaning that it cannot be changed.

Using this service you will be permanently recording your document's cryptographic hash with it's associated information into our Private Blockchain Ledger. You will be able to recover the information stored at anytime to prove that this document or file existed on particular date & time with the associated information.

If your document is altered in any way, the cryptographic hash stored on the blockchain will not match your document. Cryptographic hashes are one-way, meaning that you will never be able to re-create your document using the hash

How it works?

• Step 1: Fill your name, email address & upload the file to record. Note that we will not store your file on our server. We are only recording the cryptographic hash of your file
• Step 2: We will email you a link to retrieve information stored on the blockchain
• Step 3:Share this link with anyone you want to prove the existence of the file
• Note: Anyone with link must also have the file to verify that the signature stored on the blockchain matches the one for the file. If you lose this link with the Transaction Hash, there is no way to recover the information stored on the blockchain

How can I use it?

Demonstrating data ownership without revealing actual data.

Document time stamping.

Proving document possession at point in time

Verifying if a previosly held document has been altered
