What we build: digital public goods
Cos72 (community OS), Sin90 (personal OS) and AAStar Infra (AirAccount · SuperPaymaster · CometENS) — open, free and permissionless. Anyone can use, fork or self-deploy.
⚙️ How it works: All code is open-source on GitHub; the hosted version is free for communities, with running costs covered by grants.
💡 Why it matters: Public infrastructure for individuals → communities → cities, owned by no platform.
