What is the Context of Blockchain Security Model?

News frequently reports on the strengths and vulnerabilities of various blockchain security models, particularly in relation to high-profile hacks or network upgrades. Debates often revolve around the trade-offs between decentralization, scalability, and security in different protocol designs. Understanding a project's security model is essential for evaluating its long-term viability and resistance to external threats.

Blockchain Security Model

Definition

A Blockchain Security Model describes the architectural principles and mechanisms used to safeguard a distributed ledger system from attacks and unauthorized alterations. It encompasses cryptographic assurances, consensus algorithms, and network decentralization to maintain data integrity and transaction validity. The model dictates how new blocks are added and verified, ensuring resistance to tampering and censorship. Its robustness is central to the reliability of any blockchain application.
