On Ethereum, consensus mechanisms such as Proof of Stake (PoS) ensure everyone sees the same data and that new blocks are valid. For web3.js development, this means dApps rely on the network’s consensus to keep transactions secure and prevent double-spending. Developers do not need to build consensus themselves—it’s provided by Ethereum, allowing web3.js apps to work with reliable, secure blockchain data.
