Protocol Core

Definition ∞ The Protocol Core represents the fundamental set of rules, algorithms, and data structures that define the essential operation of a blockchain or decentralized system. It includes the consensus mechanism, transaction validation rules, and the basic ledger structure. Any alteration to the protocol core typically requires a hard fork and broad network consensus, as it forms the bedrock of the system’s security and functionality. This core dictates how participants interact and maintain the network.
Context ∞ Debates surrounding the Protocol Core often center on governance mechanisms for implementing upgrades and ensuring the long-term decentralization of a network. Discussions also involve balancing innovation with stability, as changes to the core can have widespread and unpredictable consequences. Future research explores adaptive protocol core designs that can evolve more seamlessly while preserving the integrity and security of the underlying blockchain.
