Towards the Blockchain Technology for Ensuring the Integrity of Data Storage and Transmission

摘要

Ensuring the security and integrity of data storage and transmission is a big challenge. One of the methods of its provision is the use of cryptographic techniques, which unfortunately require an additional time associated with the need for data encryption. The paper presents the solutions that ensure the data integrity, using blockchain technology. It describes two cases - an end-to-end verifiable blockchain-based electronic voting system with the ability to follow and verify votes and election results and a lightweight blockchain based protocol for secure data transfer to ensure the integrity of transferred data with a minimal cryptographic overhead.
