Heliax is a R&D team focused on implementing cutting-edge research from numerous disciplines (distributed systems, PLT, zero-knowledge cryptography) and deploying them to solve hard problems in the blockchain space, such as scalability, high assurance smart contract and validity predicate languages, secure randomness or privacy. In addition to the open-source R&D areas, Heliax is expanding its focus towards mainstream end-users, with the goals of making financial sovereignty, privacy-enhancing, and secure technologies as accessible for as many people as possible.

The primary project of Heliax is the Anoma protocol, in addition to open-source projects for the Anoma ecosystem, which include cryptographic libraries such as the MASP or tools for high assurance validity predicates and arbitrary zero-knowledge circuits (Juvix).
