The BSV blockchain uses a proof-of-work consensus system, in which miners compete to solve complex mathematical puzzles in order to validate transactions and add them to the blockchain. This system ensures that the blockchain remains secure and decentralised, with no single entity or group having control over it. The proof-of-work consensus algorithm also incentivises miners to contribute to the network by rewarding them with new bitcoins for their efforts. This helps to maintain a healthy and vibrant ecosystem for the BSV blockchain.

The Ethereum blockchain is a decentralized platform that enables the creation of smart contracts and dApps. It uses a proof-of-stake consensus algorithm, in which validators compete to validate transactions by staking their ETH tokens. The network's programming language, Solidity, allows for the creation of customized applications across a wide range of industries.
