Why Caldera + bitcoinOS
Caldera, as one of the most reliable and widely adopted RaaS providers in the ecosystem, has multiple production chains already online and is deeply integrated into a modular technology stack. Meanwhile, bitcoinOS is building an infrastructure layer that enables rollups to reliably settle to Bitcoin and Bitcoin Adjacency Networks using modern cryptography, trusted execution environments, and zero-knowledge proofs.
The combination of BOS and Caldera offers a powerful synergy: rapid rollup deployment through Caldera's proven tools; a flexible execution environment (OP Stack, Arbitrum-style architecture, etc.); Bitcoin-native security primitives through BOS; and a clear upgrade path to decentralized ordering, ZK proofs, and external state anchoring. This collaboration lowers the barrier to launching serious, production-ready rollups while providing future-proofing for a multi-chain, Bitcoin-centric world.
Capability enhancement brought about by this collaboration
1. Rollup that can be used from day one
Caldera's technology stack already supports multiple real-time blockchains and has a mature operating model. BOS-aligned projects can use Caldera as their preferred RaaS provider, maintaining complete flexibility in execution and settlement options while minimizing custom engineering requirements, significantly reducing integration risks, and accelerating mainnet launch time.
2. Trusted Infrastructure under Modern Security Assumptions
bitcoinOS integrates Trusted Execution Environments (TEEs) such as AWS Nitro, supporting secure batch deployment, proof generation, and verification workflows. Combined with the Caldera infrastructure, the chain can ensure correctness and finality guarantees at the infrastructure layer, reducing reliance on a single operator and preparing for advanced proof systems without later re-architecting, resulting in a cleaner, more auditable trust model.
3. A clear evolutionary path for ZK proofs and external state anchoring
Caldera's modular architecture allows the chains launched today to evolve in the following directions: ZK-based state proofs (through partners like Succinct), external network verification, and direct state anchoring to Bitcoin-adjacent chains such as Litecoin. This ensures that the chains can not only scale but also settle with meaningful security guarantees.
4. Flexible modular sorting
It supports starting with a centralized sorter for simplicity and performance, and upgrading over time to a decentralized or shared sorting model, maintaining consistent finality and verification guarantees throughout the transition. Teams can optimize for speed early on without compromising decentralization later, without being forced to rewrite or getting stuck in a technical dead end.
A stronger developer ecosystem
For teams building with Caldera and bitcoinOS, they gain access to a proven rollup infrastructure, Bitcoin-aligned settlement and proof-of-concept systems, flexible options across execution, ordering, and settlement layers, and the ability to expand their positioning chain as the BOS ecosystem grows to integrate with the wider ecosystem. In short: get started fast now, harden later—no regrets.
This collaboration is part of a broader effort by bitcoinOS to work closely with leading infrastructure providers of modular technology stacks, with Caldera playing a key role in this vision to make advanced rollup architectures accessible, reliable, and production-ready. In the coming months, BOS and Caldera will collaborate on providing joint support for ecosystem rollups, deeper integration with proof and verification layers, and joint marketing efforts for Bitcoin-aligned rollup projects.
