Public Blockchain

Definition ∞ A ‘Public Blockchain’ is a distributed ledger system that is open for anyone to participate in, read transactions, and contribute to the consensus process. These networks are characterized by their decentralized nature and the absence of a single controlling entity. They form the foundation for many cryptocurrencies and decentralized applications.
Context ∞ The ongoing development and adoption of ‘Public Blockchains’ are central to the broader cryptocurrency landscape, with debates often focusing on their scalability, transaction costs, and environmental impact. Key discussions involve the comparative advantages of different public blockchain architectures. Future developments to watch include the implementation of scaling solutions and the increasing integration of public blockchains into various industries.
