Protocol Upgrade

Definition ∞ A protocol upgrade is a modification or enhancement to the rules and code that govern a blockchain network or decentralized application. These upgrades are designed to improve functionality, increase security, enhance scalability, or introduce new features. They often require a coordinated effort from network participants, including developers, validators, and users, to ensure smooth implementation and widespread adoption. Successful protocol upgrades are vital for the long-term evolution and viability of blockchain ecosystems.
Context ∞ Protocol upgrades are a frequent catalyst for news and discussion within the cryptocurrency space, often signaling significant shifts in a network’s capabilities or economic model. Recent upgrades often focus on improving transaction throughput, reducing gas fees, or bolstering network security. The process of implementing these upgrades, including contentious hard forks and community consensus, is a critical area of observation for market participants.
