Achain is a public blockchain platform enabling developers of all levels of experience to issue tokens, smart contracts, create applications and blockchain systems. Achain is committed to building a global blockchain network that facilitates information exchange and value transaction. Achain was originally developed by the Singapore-based nonprofit organization, Achain Foundation, which is co-constructed and co-maintained by its fan communities around the world. At its early stage of development in 2015, Achain proposed its blueprints of technological innovations, including modular design and smart sandbox, which cultivates a more stable and secure network for decentralized applications on its platform. As the blockchain technology made further advancement, Achain, in 2017, proposed its three-phase development plan of “Smart Contract Network”, “Fork Network”, and “Interconnected Network”. Achain led the in-depth research and development of Sub-chain, BaaS, Event-Driven Mechanism and Safety Isolation.
