In the Blockchain consensus algorithm domain, the Delegated Proof of Stake or DPoS voting schema used a reputation-based voting approach to reach consensus and any user who has holdings can vote on which nodes should validate transactions on the network. A user's voting power is determined by the size of holdings he or she stakes. In this study, we proposed a revised DPoS schema, the Preferential Delegated Proof of Stake (PDPoS), as a new variety of DPoS. This algorithm allows blockchain to have an L2 network on top of the existing network or mainnet. Users could choose to send the transaction request to either L2 or the mainnet for processing. This consensus schema would improve the network's transaction speed by decongesting the mainnet and allow users to benefit from the capabilities of blockchain at a lesser cost.
