Problem
Bitcoin’s base layer lacks scalable transaction throughput and privacy features, limiting its use for complex decentralized applications. Existing layer‑2 solutions are scarce, and developers have limited infrastructure to build high‑performance Bitcoin‑based protocols.
Solution
Chainway provides the core infrastructure for Bitcoin’s first zero‑knowledge (ZK) rollup, Citrea, enabling high‑throughput, low‑cost transactions while preserving Bitcoin’s security guarantees. By integrating ZK proof systems with Bitcoin’s settlement layer, Citrea allows developers to execute complex smart contracts off‑chain and settle them on Bitcoin with cryptographic certainty. The platform also offers cross‑compatibility with Ethereum, allowing assets and data to move between ecosystems. Chainway’s research‑driven approach ensures continuous optimization of proof generation, validator performance, and network scalability, delivering a production‑ready environment for Bitcoin‑centric decentralized applications.
Target Audience
Primary customers are blockchain developers and teams building decentralized finance, NFT, and enterprise applications that require Bitcoin’s security combined with scalable, privacy‑preserving transaction processing.
