Inductive Invariants

Definition

Inductive Invariants are properties that hold true at every step of an algorithm’s execution, from its initialization through each iteration. In the context of formal verification for smart contracts and blockchain protocols, establishing inductive invariants is a method to prove the correctness and safety of a system. By demonstrating that a property remains valid throughout a process, developers can ensure the system behaves as intended under all conditions. This technique is vital for rigorous system analysis.
