Digital Notary

Check a certification


To be able to certify any digital document in a quick and easy way, using blockchain and asymmetric cryptography technology.

Digital notary service

Litra offers the digital notary service, with which any digitizable fact can be recorded using a smart contract.

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 then be created that will be written to the blockchain, and 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 access said content in an understandable manner.

That the certificate was fraudulent would mean that a malicious third party would have to access and modify the content of the complete blockchain of all Litra nodes, the cloud service servers where backup copies are stored (such as Google Drive), and also access and delete or modify all backup copies distributed throughout the world present in the client programs.
