A State-of-the-Art Blockchain Approach to the ETSI Implementation for Long-Term Preservation Solutions

Abstract

Lately, blockchain technology has been used in various use case scenarios. Our research focuses on whether long-term preservation of digital signatures/seals (for which we introduce the abbreviation LTP-DS) solutions could benefit from using this technology. In this paper, we give an outline on the stateof-the-art blockchain-based LTP-DS-related solutions, while considering the ETSI standards for LTP-DS, and offer directions on how such systems could be implemented.
