The best block chain is the most-difficult-to-recreate chain, which is really the longest branch of the blockchain tree. Currently, Bitcoin nodes are following these primary Consensus Rules: Bitcoin Controlled Supply Rule - Total supply of Bitcoins is controlled to a fixed number of 21 million...
the \name consensus protocol optimistically accepts all formally correct blocks and organizes them as a \tg (instead of a tree or a chain), and then specifies a total order of blocks in the \tg following the \oldversion{Conflux consensus rules in \cite{Conflux}} \newversion{GHAST rule}....
The method comprises: a block generation node in a blockchain continuously generates at least one block, and broadcasts the block after signing on the block; a consensus node in the blockchain receives the block and verifies whether the block is valid according to a preset rule, and if yes...

Consensus is the rule that maintains the normal operation of the blockchain. The formation of consensus is a process that allows each node in the blockchain to maintain consistent data. However, the existing consensus formation methods lack concession negotiation. The process of consensus formation ...
such as the longest chain rules. Similar rules are used such as confirming the new block by using the weight, age, etc. For DAG-based systems, things could be more difficult. For instance, DAG-based distributed ledgers that utilise PoW cannot simply use the longest chain rule to reach an...
Unsupervised, supervised, and rule-based ML approaches23 are vital in responding to and detecting microgrid attacks in blockchain networks. ML techniques may also be used to solve communication and behavior-based attacks. ML-based hybrid consensus algorithms improve security and other performance factor...
Listing 2 shows the block hash check. A proposed block has to prove the proper amount of work has been performed by finding a nonce that produces a proper hash based on the rule set by the protocol. In the Ardan blockchain, that is a hash with a number of leading zeros that match th...
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...
Appending blocks to blockchain Now, we understand how transactions are added to a block. In this section, we'll look at how a block is added to the blockchain. We already know that the block header contains mixHash and nonce, which prove the sufficiency of the computations performed on th...
