Char Network is a proof-of-stake application coordination protocol built on Bitcoin. By anchoring data into Bitcoin through cryptographic proofs and economic guarantees, Char powers the next generation of Bitcoin layer twos and applications.
We’re a small, sharp, and adventurous team led by Bitcoin developer Jeremy Rubin, pushing the limits of what Bitcoin can be. Our work blends deep protocol expertise with a hacker’s creativity to unlock new capabilities for Bitcoin at scale.
We keep things collaborative, fast-moving, and fun—where every contribution counts and every voice matters. Joining Char means working at the frontier of Bitcoin R&D and infrastructure.
