At Veriphant, we make use of the world's most powerful supercomputer to make data completely immutable. This supercomputer or network of computers is known as the Blockchain, and is the transactional ledger for the crypto-currency Bitcoin. By creating small transactions, we’re able to insert plain-text cryptographic representations of your data into the irreversible digital currency ledger. We offer data storage too, so you never lose the original file which was finger-printed! You can even add a password, or encrypt your data, or you can look after your own data and only submit the finger-print representation.
We put the following cat in the Bitcoin Blockchain (Technically, by proxy):
The SHA-256 cryptographic finger-print is 58178be94b9419cad7e5d3b4f53657dee02e010f3a87b81e8a90d63a96dd5ffc which can be seen within this https://bitaps.com/2189c38f75a9895be217f5cd5203a31ddaeb6843ea5dfa2e81b91221ff3b1d99 Bitcoin transaction.
All you need to keep for verification is the original file (Unchanged) and the Bitcoin transaction ID, or just save the handy Veriphant receipt URL which contains everything you need: https://veriphant.com/data-finger-print:58178be94b9419cad7e5d3b4f53657dee02e010f3a87b81e8a90d63a96dd5ffc/bitcoin-transaction-ID:2189c38f75a9895be217f5cd5203a31ddaeb6843ea5dfa2e81b91221ff3b1d99/receipt/
