Consensus plays a crucial role in blockchain technology, with the deleted proof of stake (DPoS) consensus mechanism commonly utilized in both public and hybrid chains. However, the current DPoS mechanism faces
The original consensus algorithm in a blockchain network is Proof of Work (PoW). The algorithm confirms the transaction and adds another block to the chain. Minors (a group of people) compete against each other to complete the network transaction in this method. Mining is the process of ...
This unique consensus mechanism incorporates time into the blockchain to reduce the load on network nodes during block processing. It operates like a cryptographic time stamp. This process eliminates solving for the time of transactions as it is in the proof of work (PoW) algorithm. For example...
Proof of workis the first Blockchain algorithm introduced in the blockchain network. Many blockchain Technologies use this Blockchain consensus model to confirm all of their transactions and produce relevant blocks to the network chain. Thedecentralization ledgersystem collects all the information related...
versionof the PoW consensus algorithm. In this consensus method, the blockchain network takes periodic snapshots of itself which are then written into a block on the network as part of a notarization process. This process helps to create a backup of the entire system on the blockchain. ...
A consensus algorithm in blockchain is a set of rules used by blockchain nodes to achieve agreement on a shared state of the network. Consensus algorithms determine what information is included in a block and which nodes are allowed to record transactions within the network. These algorithms are...
Proof of Stake (PoS)[25]is aconsensus algorithmthat relies on the crypto-currency of the blockchain user. In a Proof of Stake system, the creator of the next block is determined by a random system that is, in part, dictated by how much crypto-currency a user holds or, in some cases...
It's also the oldest consensus algorithm and is known to work well on blockchains. 2. Delayed Proof of Work Delayed Proof of Work (dPoW) is a modified version of the PoW consensus algorithm. In this consensus method, the blockchain network takes periodic snapshots of itself which are ...

Though all these algorithm has the same goal of coming to consensus in a decentralized platform, each has a different strategy with each having its own pros and cons. So, if you are looking for a perfect consensus algorithm for your custom private or permissioned blockchain platform, get in ...
