BLOCKCHAIN TECHNOLOGY: ANALYSIS AND SYNTHESIS
Abstract. The role of the blockchain technology in decentralization of the modern computer system is discussed.
Authors analyze general model of operation of the blockchain system. The idea of a new type of consensus protocols
(proof-of-accuracy protocol) is proposed. According to authors’ opinion, the new protocol have the benefits of “proof-of-work”
and “proof- of-stake” protocols. The ways of implementation of the “proof-of-accuracy” protocol are discussed.
Keywords: distributed computing systems, information security, cryptology, blockchain, cryptocurrency, consensus protocols,
proof-of-accuracy consensus protocol.
