Digital Notary

Check a certification


Being able to record any information forever, through blockchain technology.

Digital notary service

Litra offers the digital notary service, which through an intelligent contract any digitizable fact can be recorded.

Through the Litra client program you can access this service, and in a simple way upload the content you want to certify. A smart contract will be created and written to the blockchain. It will remain accessible for life.

The client can choose whether to encrypt the content or not. If it is encrypted, only those who provide the keyword will be able to understandably access to the content.

It is important to note here that Litra does not impose worldwide legal validity on what is certified (it does not have the competence to be a world notary). Litra certifies what has been sent by the client; thanks to the fact that it is sent to a trusted third party that corroborates it (the company AL1 Project S.L), and there are backup copies that prove it throughout the world (thanks to all litra users).

For the certificate to be fraudulent would mean that a malicious third party should access and modify the content of the blockchain of all Litra nodes, of the AL1 Project S.L servers, and also access and delete or modify all backup copies (spread all over the world present in client programs).

In addition, the Litra Project intends to collaborate with other trusted third parties of wide prestige, as well as with governments, with the intention that in the future they will help the jurisprudence of each country to allow the legal validity of what is certified.
