Private vs Public Blockchains

Private blockchains are restricted networks accessible only to specific participants, such as a company's internal team, providing greater control and privacy. Public blockchains, like Bitcoin or Ethereum, are open to anyone, allowing decentralized participation and transparency. Private blockchains are typically faster and more efficient, suitable for enterprise use, while public blockchains prioritize openness and security through decentralization. The choice depends on whether privacy and speed are prioritized over widespread accessibility and transparency.
