Proof of Work (PoW) vs. Proof of Stake (PoS) by BlockchainBridges < The best way to learn a new thing is doing it! > Proof of Work (PoW) and Proof of Stake (PoS) are two different consensus algorithms that are used to secure blockchain networks and ensure that transactions are valid. Proof of Work (PoW) is a consensus algorithm that requires miners to perform a certain amount of computational work in order to validate transactions and create new blocks on the blockchain. Miners compete to be the first to solve a complex mathematical problem, and the first miner to solve the problem gets to create a new block and add it to the blockchain. PoW is used by many cryptocurrencies, including Bitcoin and Ethereum. Proof of Stake (PoS) is a consensus algorithm that requires network participants to show ownership of a certain number of tokens in order to validate transactions and create new blocks on the blockchain. Instead of competing to solve a mathematical problem, ...
