We’re excited to announce a new ecosystem partnership between BOS (BitcoinOS) and Caldera, bringing together best-in-class rollup infrastructure with Bitcoin-native security and next-generation modular design.

This collaboration enables builders to launch high-performance rollups that benefit from Caldera’s production-grade Rollup-as-a-Service stack, while seamlessly integrating with BOS’s trust-minimized settlement, proof systems, and Bitcoin-adjacent anchoring roadmap.

Together we’re bringing faster rollups, fewer trust assumptions, and a clean path to Bitcoin-level security—without sacrificing developer velocity.

Why Caldera + BOS

Caldera has emerged as one of the most reliable and widely adopted RaaS providers in the ecosystem, with multiple production chains live and deep integrations across the modular stack. Meanwhile, BOS is building the infrastructure layer that allows rollups to settle credibly to Bitcoin and Bitcoin-adjacent networks, using modern cryptography, trusted execution environments, and zero-knowledge proofs.

Together, BOS and Caldera offer a powerful combination:

• Rapid rollup deployment via Caldera’s proven tooling

• Flexible execution environments (OP Stack, Arbitrum-style architectures, and beyond)

• Bitcoin-native security primitives through BOS

• A clear upgrade path toward decentralized sequencing, ZK proofs, and external state anchoring

This partnership lowers the barrier to launching serious, production-ready rollups—while future-proofing them for a multi-chain, Bitcoin-centric world.

What This Partnership Enables:
Production-Ready Rollups, Day One

Caldera’s stack is already powering multiple live chains, with long-running production deployments and a mature operational model. Through this partnership, BOS-aligned projects can leverage Caldera as their preferred RaaS provider, minimizing custom engineering while maintaining full flexibility over execution and settlement choices.

This dramatically reduces integration risk and accelerates time-to-mainnet for new rollups.

Trusted Infrastructure with Modern Security Assumptions:

BOS integrates trusted execution environments (TEEs)—such as AWS Nitro—to support secure batch posting, proof generation, and verification workflows. When combined with Caldera’s infrastructure, this allows chains to:

• Ensure correctness and finality guarantees at the infrastructure layer

• Reduce reliance on single operators or opaque off-chain processes

• Prepare for advanced proof systems without re-architecting later

The result is a cleaner, more auditable trust model that scales with the ecosystem.

A Clear Path to ZK Proofs and External State Anchoring

One of the core goals of BOS is to enable rollups to prove their state externally, using zero-knowledge proofs, and anchor that state to robust, censorship-resistant networks.

Through Caldera’s modular architecture, chains launched today can evolve toward:

• ZK-based state proofs (via partners like Succinct)

• Verification by external networks and operators

• Direct state anchoring to Bitcoin-adjacent chains, such as Litecoin, as part of BOS’s roadmap

This ensures that chains don’t just scale—but settle with meaningful security guarantees.

Modular Sequencing, Without Lock-In

Caldera and BOS support a flexible approach to sequencing:

• Start with centralized sequencers for simplicity and performance

• Upgrade over time to decentralized or shared sequencing models

• Maintain consistent finality and verification guarantees throughout the transition

This lets teams optimize for speed early, without compromising on decentralization later. No forced rewrites. No dead ends.

What This Means for Builders

For teams building on Caldera with BOS:

• You get battle-tested rollup infrastructure today

• You gain access to Bitcoin-aligned settlement and proof systems

• You retain optionality across execution, sequencing, and settlement layers

• You position your chain to integrate with the broader BOS ecosystem as it expands

In other words: launch fast now, harden later—without regrets.

Looking Ahead

This partnership is part of a broader effort by BOS to work closely with leading infrastructure providers across the modular stack. Caldera plays a critical role in this vision by making advanced rollup architectures accessible, reliable, and production-ready.

Over the coming months, BOS and Caldera will collaborate on:

• Joint support for ecosystem rollups

• Deeper integrations with proof and verification layers

• Shared go-to-market efforts for Bitcoin-aligned rollup projects

We’re excited to support the next generation of rollups—and to help them settle on foundations that actually matter.
