HOP Ledger
HOP Ledger is more than a technology
It’s a strategy.
The HOP Ledger project aim to embedded pearls and jewels certificates in the permanent and secure worldwide blockchain network.
The blockchain network is a really big record book based on thousands worldwide computers linked together able to maintain forever the pearls and jewels certificates.
Records in the blockchain are impossible to tamper with or forge.
That entries in the blockchain can never be changed and are secure.
This makes for the perfect record keeping technology.
Recording it in a transaction on the blockchain works like a time stamp.
This technology is already used worldwide to create legal proof.
Certificates are sealed forever, valid worldwide, legally binding and their authenticity can be easily verified.
HOP Ledger works like a permanent and immutable ledger for pearls and jewels certification with a unique identifier.
HOP Ledger is fully compatible with your homemade certificates.
Just provide your certificates in a JPEG or PDF format to the HOP Ledger.
We will embed them for you in the blockchain and give you back the information on the transaction that prove it has been embedded in the blockchain network.
Download you certificat below (PDF or JPEG)
We will send you back the Hash 256 corresponding and the instructions.
How does it work ?
Create your own certificate or load the certificate example form.
Apart from text and pictures, PDF files can contain other information such as logical parts, pictures, tables and signature if needed.
The document size is not limited.
Upload your PDF in the HOP Ledger certification program.
From your document we calculate automatically a unique ID number.
To do that we use a Secure Hash Algorithm SHA 256 that give us a unique ID Number like this one:
45A7B8A4C84C26254717721552E92811D9AD51A48D9BE6FA3BD76A32C0D95743
We had automatically complementary security and identification coding to give an information compatible with the blockchain network.
We send it to the blockchain public ledger maintained in the decentralized bitcoin cryptocurrency network.
You don't have to worry about your data being accessed by others in the blockchain.
Your document is NOT stored in the bitcoin blockchain.
In return we get an acknowledge ID Transaction number which has allowed the inclusion of the data block we have submitted like this one (example) :
d4ff86e0a8a1314b9007abdb91b7865a46193c13adf11ae96b00793961737dbd
The unique ID transaction number:
d4ff86e0a8a1314b9007abdb91b7865a46193c13adf11ae96b00793961737dbd
may be certified using any standard blockchain explorer like the following.

Your ID certificate transaction is already embedded forever in the Blockchain network with a legal time stamp.
