Blockchain technology has fundamentally changed how we see financial transactions by enabling secure, open, and decentralized financial transactions. Blockchain technology is used by digital assets like cryptocurrency, and two techniques stand out for validating blockchain transactions: Proof of Work and Proof of Stake. Consensus methods of Proof of Work (PoW) and Proof of Stake (PoS) are used to validate transactions on a blockchain network and add new blocks to the chain. The blockchain network's original consensus algorithm was PoW. However, PoS has since been devised as a substitute. Miners are PoW validators, while validators or forgers are PoS validators.
Before adding new blocks to the blockchain, the process of proof-of-work (PoW) mining necessitates using cryptographic calculations to solve challenging mathematical problems. The first miner to identify the issue and validate the block is rewarded for their efforts. PoW mining is expensive to operate and maintain because it uses many computer resources and electricity.
In contrast, PoS validators validate transactions by putting their own cryptocurrency on the line. Validators have a stake in a fixed quantity of cryptocurrency, which serves as collateral and is temporarily frozen. The network selects PoS validators at random based on the staked amount of cryptocurrency, and the validators are paid transaction fees for validating blockchain updates.
