Definition ∞ Structural network change refers to a fundamental alteration in the underlying architecture or operational mechanisms of a blockchain or distributed ledger technology. These changes often involve significant protocol upgrades, modifications to consensus mechanisms, or the introduction of new data handling methods. Such alterations aim to improve scalability, security, or decentralization. They represent a major evolution in the network’s design and capabilities.
Context ∞ The discussion surrounding structural network changes is constant within the rapidly evolving blockchain space, as protocols continuously seek to optimize their performance and utility. Major upgrades, like Ethereum’s transition to Proof of Stake, exemplify these significant shifts. A critical future development involves the careful planning and community consensus required for implementing these complex changes, ensuring network stability and continued participation while pursuing technological advancement.
