Strongest Chain Rule

Definition ∞ The strongest chain rule is a principle in certain blockchain protocols, predominantly proof-of-work systems, which dictates that the valid chain is the one that has accumulated the most computational work. In the event of a fork, nodes follow the chain with the highest difficulty, as it represents the greatest expenditure of mining effort. This rule ensures network agreement on the canonical history.
Context ∞ This rule is fundamental to the security and operation of Bitcoin and other proof-of-work cryptocurrencies. News often references the strongest chain rule when discussing network forks, 51% attacks, or consensus issues. It serves as a robust mechanism for resolving discrepancies and maintaining the integrity of the distributed ledger against malicious attempts to alter history.

Translucent blue, intricately structured modules are displayed, possibly representing cryptographic primitives or smart contract logic within a decentralized ledger technology DLT framework. These interconnected elements, covered in fine droplets, suggest active data immutability and network consensus processes. A prominent metallic component, resembling a hardware security module HSM or validator node hardware, anchors the system, emphasizing robust digital asset protection and transaction finality. This visual metaphor illustrates the complex interplay of blockchain architecture and security protocols in a Proof-of-Stake PoS environment.
