A network security model defines the architectural framework and operational procedures designed to protect a blockchain network from attacks, vulnerabilities, and unauthorized access. This encompasses the consensus mechanism, cryptographic primitives, and economic incentives that collectively secure the network’s integrity and availability. A robust security model is paramount for ensuring the trustworthiness of transactions and the immutability of the ledger. It dictates how the network resists malicious actors.
Context
News frequently reports on the strengths and weaknesses of various network security models, especially when discussing major blockchain upgrades or incidents involving exploits. Debates often compare proof-of-work versus proof-of-stake security assumptions and their respective resilience against different attack vectors. The ongoing evolution of these models is a constant focus for protocol developers and a key factor in assessing the long-term viability of digital asset platforms.
