The structure of logical consequence : proof-theoretic conceptions [PDF]
, 2010 The model-theoretic analysis of the concept of logical consequence has come under heavy criticism in the last couple of decades. The present work looks at an alternative approach to logical consequence where the notion of inference takes center stage ...

Performance analysis and comparison of PoW, PoS and DAG based blockchains
Digital Communications and Networks, 2020 In the blockchain, the consensus mechanism plays a key role in maintaining the security and legitimation of contents recorded in the blocks. Various blockchain consensus mechanisms have been proposed.

Proof of Experience: empowering Proof of Work protocol with miner previous work
International Journal of Blockchains and Cryptocurrencies, 2020 Even after 12 years of services, Bitcoin still remains the first e-cash system and most influential player in the cryptocurrency market. For each block, the underlying distributed Proof of Work consensus where much computing power (named miners) is required to solve a hard mathematical problem, rewards the first one solving and sharing the solution ...

Better Incentives for Proof-of-Work
, 2022 This work proposes a novel proof-of-work blockchain incentive scheme such that, barring exogenous motivations, following the protocol is guaranteed to be the optimal strategy for miners. Our blockchain takes the form of a directed acyclic graph, resulting in improvements with respect to throughput and speed.

Cryptocurrencies Without Proof of Work [PDF]
, 2016 We study decentralized cryptocurrency protocols in which the participants do not deplete physical scarce resources. Such protocols commonly rely on Proof of Stake, i.e., on mechanisms that extend voting power to the stakeholders of the system. We offer analysis of existing protocols that have a substantial amount of popularity.

On the Issue of Using “Useful” Tasks for Proof of Works in Blockchain
Моделирование и анализ информационных систем, 2019 This paper is a logical continuation of the paper about possible approaches to solving the “Useful Proof-of-work for blockchains” problem. We suggest some alternative ways for searching useful tasks for Proof-of-work systems.
