Crypto Public Notary - Notarize Digital Work with Bitcoin
▻http://www.cryptopublicnotary.com
First: You create awesome content
Text, video, image, source code, contracts, deed or title. However you express yourself, whatever document you wish to record, literally, any kind of digital file works.
Next: We notarize your file
Crypto Public Notary turns your file into a Bitcoin Address in the browser. The file’s SHA256 Checksum is used as the Bitcoin private key to derive the address. You retain the original copy and your content never touches our servers. It works offline.
Then: Send some bitcoin
Send a trivial amount of bitcoin to the address. Proof of your document’s existence is now recorded forever on the Bitcoin block chain.
Retrieve your coins: You have the keys
Our process also returns a WIF private key. You can import this key and retrieve your bitcoin. Cryptographic provenance will never cost you more than miners’ fees.
Enregistrer dans la blockchain Bitcoin (horodatée et infalsifiable jusqu’à preuve du contraire) le hash d’un document, permettant ainsi de prouver son existence à un instant T. Pratique. Avant il fallait trouver un notaire, payer, attendre...
Mais reste une question : quel tribunal sera prêt à reconnaître la preuve ? Si cela arrive et que le cas fait jurisprudence, on peut s’attendre à un beau succès de ce type de solutions.
Pour mémoire, je vous parlais déjà d’un PoC similaire sous Android : ►https://github.com/ligi/SatoshiProof
