Definition ∞ Long-term liveness, in blockchain contexts, refers to a network’s sustained ability to process and confirm transactions and produce new blocks reliably over an extended period. This property is essential for the ongoing functionality and utility of any decentralized system. It ensures that the network remains operational and responsive to user requests. Maintaining liveness is a primary goal of protocol design.
Context ∞ News often discusses long-term liveness when evaluating the security and stability of proof-of-stake blockchains, particularly during network upgrades or periods of low validator participation. Concerns arise if a network faces conditions that could impede block production. The mechanisms designed to guarantee this property are a recurring topic in blockchain research and development.
