    2. 0.4. Why Public Chains Matter

A Public Chain is a fully open blockchain network where anyone can join, read data, submit transactions, and participate in consensus without permission.

What Defines a Public Chain

Public chains are decentralized and transparent by design. All transactions are visible to the public, and network participation is unrestricted. Well-known examples include Bitcoin, Ethereum, and Solana. These blockchains typically use consensus mechanisms like Proof of Work or Proof of Stake to maintain security and integrity.

Why Public Chains Matter

Public chains promote inclusivity, censorship resistance, and trustless interaction. They are the backbone of decentralized finance (DeFi), NFTs, and countless other Web3 innovations. Because no central authority controls access or data, public blockchains are ideal for building open and permissionless applications.
