Overview
MLabs is a software engineering firm specialising in functional programming and formal methods, working largely on blockchain protocols, smart contracts and high-assurance systems. Its engineers work predominantly in Haskell and related languages, which is unusual commercially and gives it a niche in projects where correctness has to be demonstrated rather than tested, particularly in the Cardano ecosystem. Registered in London and operating as a distributed organisation, it takes on protocol development, audit and formal verification work for clients whose systems hold value that a defect would put directly at risk.

Products
Haskell Engineering
General functional programming consultancy for clients with high-assurance requirements. The talent pool is small enough that the firm's ability to recruit within it is itself a durable competitive position.
mlabs.city
Smart Contract Audit
Independent review of contract code before it is deployed to a live chain. Auditors are held to account by their published reports, which makes reputation the entire asset in this particular line of work.
mlabs.city
Formal Verification
Mathematical proof that code behaves according to its specification. Testing shows the absence of known bugs while verification shows the absence of whole classes of them, which matters when funds are at stake.
mlabs.city
Protocol Engineering
Development of blockchain protocols and smart contract systems. Functional programming is a deliberate choice here, because a defect in deployed contract code cannot be patched and may be directly exploitable.
