1. What Is a Public Blockchain
A public blockchain is an open, permissionless network where anyone can read, transact, or participate in consensus — Bitcoin, Ethereum, and Solana are public blockchains.
2. How It Works
Public blockchains have no gatekeepers: anyone can run a node, submit transactions, and (in PoS) validate. Security comes from economic incentives and open competition rather than permissions. Data is transparent to all. This openness maximizes decentralization and censorship resistance at the cost of scalability and privacy.
3. Why It Matters
Public blockchains are the "trustless" foundation of Web3 — permissionless money, applications, and governance. Their openness is what makes crypto a neutral, global infrastructure. The trade-off between openness and performance drives most protocol design debates.
4. Key Facts
- Anyone can participate without approval
- Consensus is open (PoW or PoS with public staking)
- All transactions are publicly visible
- Public chains face scalability and privacy constraints
