Formal verification is a way to prove a system is working correctly within its environment. Formal verification uses static analysis and a maths-based technique called formal methods in order to check the systems design and its properties. Formal verification contributes to the safety and steadiness of the system as well as the functional correctness of the smart contract.
Formal verification of a smart contract is made up of two steps: validation and verification. Validation defines the logic of the smart contract to be sure that it works as developers conceived. During verification, our experts build the mathematical specifications of the smart contract. They then compile the smart contract from a high-level language to virtual machine (VM) bytecode in order to match to the specification.
