Citrea, Bitcoin’s First ZK Rollup, Emerges from Stealth

Grand Cayman, Cayman Islands, February 6th, 2024, Chainwire

Citrea is the first rollup that enhances the capabilities of Bitcoin blockspace with zero knowledge technology, enabling developers to build everything on Bitcoin

Citrea, Bitcoin’s first ZK rollup, has come out of stealth today to enable developers to build everything on Bitcoin. Citrea is the first-ever and only execution layer that settles on Bitcoin. Every transaction occurring on Citrea is fully secured by zero-knowledge proofs and verified by Bitcoin through BitVM. Citrea represents a major milestone for Bitcoin, marking a first as the most secure way to scale Bitcoin, entirely aligning with its incentives. The developer contact form opens today for those who want to build on Citrea and its developer docs are finally unveiled to the public.

Bitcoin has faced the critical challenge of how to handle more transactions and support more diverse applications without compromising Bitcoin’s founding principles – security, consensus rules, and censorship resistance. While scalability proposals have been presented in the past, they have consistently failed to address a critical point in Bitcoin scalability – the active and effective utilization of the Bitcoin blockchain itself.

Zero-knowledge proofs are the only way to securely scale Bitcoin and achieve easy verification by the Bitcoin blockchain. ZK rollups, specifically, are the only rollup construction that can fit into Bitcoin’s block size limit effectively.

Citrea is the first to bring ZK Rollups to Bitcoin, expanding what developers can build on Bitcoin and introducing Bitcoin’s next phase: foundation for the world’s financial infrastructure. Citrea enhances Bitcoin’s blockspace capabilities. Its execution environment is trustless to Bitcoin and available to all participants of the Bitcoin network. Citrea validity proofs are inscribed in Bitcoin and optimistically verified on Bitcoin via BitVM, for the first time in Bitcoin history. By doing so, Citrea creates consistent fee revenue for miners through data availability, trustlessly scales BTC beyond Bitcoin with vali
