Lesson 3: Cross-Chain Interoperability

Crypto World - Advanced Level

← Back to Topics

What is Interoperability?

Interoperability in blockchain means the ability of different networks (like Ethereum, BNB Chain, Solana, etc.) to communicate and share data or assets with each other in a secure and decentralized way.

Why It Matters

Most blockchain ecosystems operate independently. To unlock full Web3 potential, assets and apps need to move across chains. Imagine being able to use an Ethereum token in a Solana dApp β€” that's the power of interoperability.

Real-world analogy: Different countries use different currencies. Without exchanges or conversion, trade would be impossible. Interoperability is like having instant, automatic currency conversion between nations.
