Taking Bitcoin and Ethereum as examples, they respectively adopt different consensus algorithms to ensure the security of transactions and confirmation time.↵↵The Bitcoin network uses the Proof of Work (PoW) consensus algorithm, where miners need to compete to generate blocks by solving complex mathematical problems. When a miner successfully solves the puzzle of a block, he will receive a certain amount of Bitcoin as a reward and add the new block to the blockchain. In general, the Bitcoin network requires about 10 minutes to confirm a transaction.↵↵The Ethereum network adopts a different consensus algorithm, called Casper FFG (Fault-F Tolerant Generalized Secret-Proof of Stake), which utilizes a hybrid approach of Proof of Stake and Delegated Proof of Stake. This  algorithm aims to improve the scalability and efficiency of the network while ensuring the security of transactions."}]}],"pr":"80dbe79c23cb854c7937ec10ad60981a802a11c19db232b98b85daf9edfc460f"}
