Web3.js connects dApps directly to blockchains like Ethereum, which use cryptography and decentralised networks to improve security. With web3.js apps, data is distributed, so there’s no single point where hackers can break in. Every user has their own private keys, so only they control their data and funds. Smart contract code and consensus keep everything fair and much safer than apps managed by a single company.
