Web3.js

Web3 vs traditional databases: when is blockchain justified?

The question is about Web3.js .

Answer:
Traditional databases are designed for performance, fast queries, and structured data controlled by one or several trusted parties. Blockchain-based Web3 systems are slow and hard to scale, but deliver shared, trustless ledgers and open verification. Blockchain is justified for use cases requiring decentralised trust, public audit, no central control, and transparent transactions.
