However, in the existing Blockchain, there is no mechanism to ensure the trust and robustness of the miners and eliminate the malicious miners which runs the consensus algorithm. Therefore, this paper proposes a trust model with an objective of eliminating untrusted nodes from the m...

Firstly, the position and role of consensus mechanism in the block chain are defined; secondly, the evaluation criteria and specification of consensus mechanism are grasped; thirdly, the algorithms of consensus mechanism are analyzed and compared; finally, the future development trend of consensus ...
In this post, you will learn how blocks on the Vechain Blockchain are validated to keep the Blockchain safe and secure while keeping the costs of using the Blockchain low. “At its core, designing the consensus model of a Blockchain is one of the largest decisions needed to be made.” ...
Proof-of-Play: A Novel Consensus Model for Blockchain-based Peer-to-Peer Gaming System Data storage in peer-to-peer (P2P) games in a perfect applications scenario for blockchain. However, suffering from high transaction cost and latency, proof-of-work (PoW) becomes the bottleneck of blockcha...
In the light of this limitation, we revisited the Byzantine Refining the blockchain model for consortiums As we discussed previously, the risk of safety violation of main blockchain systems stems from the impossibility of solving consensus deterministically in the general case, which also applies to...

process modeldesign principlesIn 2008, Blockchain was introduced to the world as the underlying technology of the Bitcoin system. After more than a decade of development, various Blockchain systems have been proposed by both academia and industry. This paper focuses on the consensus algorithm, ...
Minotaur: Muti-Resource Blockchain Consensus (Minotaur:多资源区块链共识) 摘要 基于资源的共识是无许可分布式账本系统的支柱。这种协议的安全性从根本上取决于系统中积极参与的资源水平。各种不同的资源(以及相关的证明协议,有时在文献中被称为 PoX)提出了一个根本问题,即是否有可能同时使用其中的许多资源并建立多...
While there are many recurring patterns and principles, Blockchain platforms have revolutionized the theory of distributed systems in how we deal with trust. In the next section, we drill down further into distributed systems and their implementation using the well-known state machine model in ...
