CertiK (CTK Token): Blockchain Smart Contract Verification System?
Blockchain technologies provide a global consistent ledger that does not rely on any trusted and centralized authority. The ledgers record virtual currencies transactions using network nodes. The central authority in these systems is replaced by the consensus among network nodes and value created through a system of decentralized trust.
Nevertheless, blockchain systems are not entirely trustable. They have a transparent policy and hackers get to benefit a lot when they attack the systems. These challenges make them highly sensitive to attacks. Today, they are more vulnerable to attacks than expected.
What Is CertiK?
Many ways can be used to improve the security and reliability of system software but none of them addresses all the challenges of the blockchain systems. It is against this background that CertiK developers developed a one-stop verification solution referred to as the CertiK platform.
Who Is Behind CertiK?
The CertiK team is made up of verification experts who are professors at Yale and Columbia Universities. The team also has software engineers from Google, FreeWheel, and Facebook. The CertiK platform provides a powerful set of certified kits for the building of fully trustworthy blockchain ecosystems.
How CertiK Blockchain Smart Contract Verification System Works
CertiK is the formal verification platform for smart contracts and blockchain ecosystems. This formal verification network mathematically proves that blockchain ecosystems and smart contracts are hacker resistant and do not have bugs.
To ensure better verification, the platform came up with a layer-based system that divides the prohibitive proof task into smaller tasks. These small tasks are then encoded in the CertiK transactions and can be validated and proved by the users in the decentralized style. Therefore the CertiK ledgers work as certificates to enable end-to-end correctness and security of the verified smart contracts and blockchain ecosystems which makes them trustworthy.
The platform has come up with a novel approach that specifies DApp system by use of labels. The labels are expressive and can state the desired properties. They are also compatible with the existing programming languages.
The CertiK team has come up with a novel concept referred to as layered deep specifications 1,2,3,4. This method uncovers the insights of layered design patterns and allows for the decomposition of a complex proof task into smaller tasks that can be verified at their proper abstraction level.
Pluggable Proof Engine
The CertiK program intends to come up with an open protocol that allows advanced algorithms to be freely plugged into the system.
Machine Checkable Proof Objects
The platform comes up with mechanized proof objects or counterexamples that allow proofs to be quickly checked by anyone using their machine. The proof of objects acts as the certificates to the verified programs.
Certified DApp Libraries
The CertiK platform provides a series of certified plug-ins and libraries to improve the code reliability and quality of the entire blockchain community.
Customized Certifications Services
For DApp systems such as digital wallets that have high-reliability needs, there will be customized certification services given by the CertiK platform. Verification experts will specify and verify the programs and come up with a detailed report.
