Definition ∞ Blockchain networks are distributed ledger systems where transactions are recorded chronologically and immutably across many computers. These networks operate without a central authority, relying on cryptographic principles to secure and validate data. They form the foundational technology for cryptocurrencies and other decentralized applications.
Context ∞ The current discourse surrounding blockchain networks frequently centers on their comparative performance, security models, and the development of interoperability solutions. Debates persist regarding the optimal consensus mechanisms and the potential for different networks to interact seamlessly. Future developments are anticipated to address limitations in transaction speed and energy consumption, alongside the expansion of enterprise adoption.
