We're thrilled to announce our partnership with BitcoinOS (BOS), a collaboration that opens a new frontier for rollup builders: the ability to launch production-ready chains today while gaining a clear path to Bitcoin-level security.
This partnership combines Caldera's battle-tested Rollup-as-a-Service infrastructure with BOS's trust-minimized settlement layer, proof systems, and Bitcoin anchoring roadmap. The result? Builders no longer have to choose between speed-to-market and long-term security guarantees.
Why This Partnership Matters
At Caldera, we've always believed that great infrastructure should meet builders where they are, and grow with them. Our Rollup Engine already powers some of the most advanced rollups in production, with flexible execution environments and deep modular integrations.
But we've heard a consistent ask from teams exploring Bitcoin-aligned architectures: How do we get the performance and reliability we need today, without painting ourselves into a corner on settlement and security?
BitcoinOS answers that question. Their infrastructure layer enables rollups to settle credibly to Bitcoin and Bitcoin-adjacent networks using modern cryptography, trusted execution environments, and zero-knowledge proofs, all without requiring teams to rebuild from scratch later.
Together, we're offering builders the best of both worlds.
What This Partnership Delivers
Launch Fast, With Proven Infrastructure
Caldera's stack is designed for production. Teams building with BOS can now leverage our Rollup Engine as their preferred deployment path, getting live faster with less custom engineering, while retaining full control over execution and settlement choices.
Modern Security, Without the Complexity
BOS integrates trusted execution environments (like AWS Nitro) to support secure batch posting, proof generation, and verification. Combined with Caldera's infrastructure, this means chains can enforce correctness guarantees at the infrastructure layer from day one.
A Real Upgrade Path to ZK and External Anchoring
Through our modular architecture, chains launched today can evolve toward ZK-based state proofs and external state anchoring including Bitcoin-adjacent networks like Litecoin, as part of BOS's roadmap. No forced migrations. No dead ends.
Flexible Sequencing, Your Way
Start with centralized sequencing for simplicity. Upgrade to decentralized or shared models when you're ready. Caldera and BOS support this progression without requiring architectural rewrites.
What This Means for Builders on Caldera
If you're building with Caldera:
You now have direct access to Bitcoin-aligned settlement and proof systems
You can position your chain to integrate with the broader BOS ecosystem as it expands
You retain full optionality across execution, sequencing, and settlement layers
Looking Ahead
Over the coming months, Caldera and BitcoinOS will collaborate on joint support for ecosystem rollups, deeper integrations with proof and verification layers, and shared go-to-market efforts for Bitcoin-aligned projects.
We're excited to support the next generation of rollups, and to help them settle on foundations that actually matter.
