What is the difference between public and private blockchain?

Public blockchains (Ethereum, Solana, Polygon) are open, permissionless, and decentralized. Anyone can participate, and data is transparent. Private/permissioned blockchains (Hyperledger) restrict who can join, read, and write. They're ideal for enterprise use cases where privacy matters but you still need immutability and multi-party trust. Our developers build on both depending on your requirements.
