Public Coin Protocol

Definition ∞ A Public Coin Protocol refers to a blockchain system that operates with a publicly verifiable cryptocurrency, where all transactions are recorded on a transparent ledger accessible to anyone. These protocols are typically permissionless, allowing any participant to join the network, contribute to consensus, and transact without requiring central approval. Bitcoin and Ethereum are prominent examples of such protocols. They form the foundation of open, decentralized digital asset economies.
Context ∞ News about Public Coin Protocols often addresses their decentralization, security, and scalability characteristics. Discussions frequently involve network upgrades, changes in consensus mechanisms, or regulatory actions impacting these open systems. The transparency of these protocols allows for public auditing of transaction history, contributing to their trust model. Understanding the principles of public coin protocols is essential for comprehending the core mechanics and societal implications of many major cryptocurrencies.
