Blockchain Consensus Protocols: State-of-the-art and Future Directions
IEEE International Conference on Tools with Artificial Intelligence, 2021Being the major disruptive technology in current era, Blockchain is becoming the prime choice for researchers and businesses. Consensus layer acts a backbone of any blockchain application; therefore to increase the performance of a blockchain ecosystem ...

Decentralized consensus protocols
[1991 Proceedings] Tenth Annual International Phoenix Conference on Computers and Communications, 2002The goal of decentralized consensus protocols is to exchange information among computers so that each computer acquires information held by every other computer in the system. The authors introduce a unifying framework which generalizes these decentralized consensus protocols.

Proceedings of the second annual ACM symposium on Principles of distributed computing - PODC '83, 1983
A consensus protocol enables a system of n asynchronous processes, some of which are faulty, to reach agreement. There are two kinds of faulty processes: fail-stop processes can only die, malicious processes can also send false messages. We investigate consensus protocols that terminate within finite time with probability 1 under certain assumptions on

Dealing with Uncertainty in Consensus Protocols
2009Recent results on consensus protocols for networks are presented. The basic tools and the main contribution available in the literature are considered, together with some of the related challenging aspects: estimation in networks and how to deal with disturbances is considered.

A Consensus Protocol With Deterministic Finality
IEEE INFOCOM 2021 - IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2021Proof-of-Validation (PoV) is a fair, immutable, and fully decentralized blockchain consensus protocol with an O(1) asymptotic message complexity. The original PoV proposal lacks deterministic finality, which guarantees that a valid block will not be revoked once it is committed to the blockchain.

A quick distributed consensus protocol
Microprocessing and Microprogramming, 1993A number of current distributed applications require the use of consensus protocols. Two well known examples are fault-tolerant applications built with process replicas in need to agree on their external behavior, and systems of replicated data where consistency has to be maintained.

An Empirical Study of Consensus Protocols’ DoS Resilience
ACM Asia Conference on Computer and Communications SecurityWith the proliferation of blockchain technology in high-value sectors, consensus protocols are becoming critical infrastructures. The rapid innovation cycle in Byzantine fault tolerant (BFT) consensus protocols has culminated in HotStuff, which provides ...

Blockchain Consensus Protocols, Energy Consumption and Cryptocurrency Prices
Journal of Energy Markets, 2020Cryptocurrencies employ different consensus protocols to verify transactions. While the “proof-of-work” consensus protocol is the most energy-consuming protocol, “proof-of-stake” and the hybrid of these two consensus protocols, which consume considerably
