Protocol Mutability

Definition

Protocol mutability refers to the capacity of a blockchain’s underlying rules and code to be changed or updated after its initial deployment. This characteristic dictates how easily a network can adapt to new technologies, fix vulnerabilities, or implement community-driven improvements. Protocols can range from highly immutable, requiring hard forks for changes, to more mutable, allowing for easier upgrades through on-chain governance. It concerns the flexibility of a system’s core design.
