The U.S. postal service (USPS) intends to patent the solution, which describes methods and systems for architecture of digital security using blockchain technology. The corresponding application was filed in September 2017, as published on the website of the Bureau for registration of patents and trademarks of the United States.

The USPS hopes to help new technologies to regain the trust of clients who are concerned about the possibility of intervention of third parties in their conduct of the transaction.

A higher level of reliability of data protection is to be achieved through the use of new measures, e.g., blocking e-mail when an unauthorized invasion and use by customers of public and private keys and the implementation of a storage-identifying information in the distributed registry. In this way, customers USPS will be able to decide whether to save information in the blockchain and confirm transactions using a token.

Recall that USPS for several years considering the possibility of introducing blockchain technology into their work. In 2016 one of the leaders of the service in a specially prepared report said that the innovation will appear in USPS, when it will be better developed.

At the same time, in other countries postal services are already implementing this technology and begin to work with kripalani. So, the Post of Russia in October 2017 engaged in the integration of technology in operations associated with the conduct of monetary transactions. And earlier, in July of the same year, email service provider, Austrian Post has added the ability to purchase bitcoins, Ethereum, Litecoin and Dash to more than 1800 offices located throughout the country.
