Abstract

Electronic voting is one of the most challenging cryptographic problems, since the developed system should guarantee strong and sometimes contrasting security properties. Blockchain technology can be of help providing for free some important guarantees such as the immutability and transparency of the votes using a distributed ledger. In this paper we propose a blockchain based e-voting system, which is lightweight, since it does not rely on strong cryptographic primitives, and efficient, since it improves over previous proposals in terms of both execution time and associated cost for the required infrastructure. We provide the description of a proof of concept system together with the cost and performance analysis.
