What is the blockchain certificate of authenticity for?
When you buy a watch, we want to provide you with proof that your watch is authentic. To this end, we issue a certificate of authenticity in your name, protected by blockchain technology. This certificate can be useful in the event that you need to contact the After-Sales Service, a dealer or anyone to whom you want to offer the watch, either in the context of a gift or a resale. With this digital certificate, you no longer need to use the physical warranty card provided with the watch, eliminating the risk of losing or forgetting it.
How do you get a blockchain certificate?
To Build a token bridge obtain a blockchain certificate, you must purchase a new watch from the official dealer network, and then register for the free extended warranty. You will then receive your certificate automatically and will also be able to access it from your customer account (in the future version of this website). Registration in the blockchain can take up to 24 hours from the request for the guarantee extension to the receipt of your certificate.
How much does the blockchain certificate cost?
This certificate is free for anyone who buys a new watch from our dealer network and requests an extended warranty (also free).
Why the blockchain?
Blockchain technology is used to create a digital singularity. In this way, a digital document (in our case, a certificate) is impossible to forge when it is protected by the blockchain. The blockchain allows you to create date-stamped certificates as proof that you bought an authentic watch. The advantage of blockchain technology is that these certificates are digital; therefore, they can be shared and stored online.
How can I verify that a certificate is authentic?
Our website has a certificate checker. By simply uploading the document on the website, you can verify that the certificate is authentic.
The following section is intended for anyone curious or with more advanced knowledge of the blockchain.
Can you explain to me what a blockchain is?
Blockchain technology is used to store information extremely securely. Thanks to the blockchain, data can be both public and tamper-proof, which represents a formidable tool for creating trust in relationships between people. Blockchain was invented in 2008 by an anonymous group using the pseudonym Satoshi Nakamoto when inventing the peer-to-peer digital currency known as Bitcoin. The blockchain was originally used as a public ledger of transactions that allowed people using pseudonyms to trade in complete confidence. This is how the Bitcoin blockchain came to be and still endures today. The term “blockchain” is used to describe both the data and the protocol that stores this data.
What blockchain does use?
We use the public Bitcoin blockchain. It is the oldest and most reliable so far. It has 10 years of life and, until now, it has never been hacked; therefore it is the safest. cross chain bridge development Other blockchains to protect our certificates might have been less expensive and faster, but we prefer the more secure and more recognized solution. In addition, we make use of “embedding” thanks to which fits in with our attitude towards protecting the environment.
Why use a public blockchain?
There are several advantages to using a public blockchain:
Maximum security thanks to considerable decentralization;
And an absolute transparency that makes the certificates verifiable.
Thanks to the combination of these two elements, trust is created and our certificates are forgery-proof. All our certificates can be verified by us or by our provider , verifying the Bitcoin block chain itself We strictly apply the blockchain principles of “decentralization” and “real ownership” to the foundation of the trust revolution provided by this new technology.
By what mechanism are certificates protected in the block chain?
Each certificate is protected according to the following protocol:
The certificate is produced in PDF format;
We sign this hash with our ID protected by an SSL certificate;
We embed this signed hash into the Bitcoin blockchain.
creates a Merkle tree with other details according to the Chain point standard.
then saves the root node of this tree in a Bitcoin transaction.
Once the transaction is approved, returns the proof of the blockchain to us in Chain point format. We consider the transaction to be approved when 6 blocks have been added to the Bitcoin blockchain after the block containing the transaction.
How can I check for myself the existence of the certificate in the blockchain?
To get your chain test in format, use your certificate checker and then click “Download chain test”. The file you will receive will be in JSON format. This format can be read in some browsers by dragging and dropping into a blank tab or by using a text editor.
Is my personal data well protected?
Yes, they are protected by several mechanisms. First of all, only the hash of the certificate is sent to our provider, so you can’t access the human-readable data. Second, we don’t put the entire hash on the blockchain through the Merkle tree. Therefore, it is technically impossible to read the data contained in the blockchain certificate.
What is a hash?
A hash is a cryptographic means of representing numerical data in a unique way. The hash for numerical data is said to be the equivalent of a fingerprint for a human. To get a hash of some data, we apply a hash function to that data.
