Core Layer

Definition ∞ The core layer is the fundamental infrastructure of a blockchain or decentralized network. This layer establishes the basic rules for consensus, transaction validation, and data storage. It provides the foundational security and immutability upon which all other network functions and applications are built. The core layer dictates the fundamental operational parameters of the entire system.
Context ∞ Discussions surrounding the core layer frequently pertain to protocol upgrades, scalability solutions, and fundamental security considerations. News articles often analyze changes to a blockchain’s core layer, such as proof-of-stake transitions or sharding implementations, due to their profound impact on network performance, decentralization, and economic models. The stability and ongoing development of this layer are paramount for the long-term viability and adoption of any digital asset ecosystem.
