· Boundless is enabling OP Rollup to achieve truly rapid finality

· This is the first non-interactive Dispute Game driven by ZK proofs

· Rollup requires only one set of smart contracts, allowing flexible switching between ZK Fault Proof and Validity Proof modes

· Leveraging Boundless Network, Rollup can access proof computing power of 400 trillion cycles daily, with median costs below $0.04 per billion cycles

· Based on current throughput, Boundless can provide approximately $29,000 worth of proof services per month for OP Mainnet (24.34T cycles/day), about $8,700 for Unichain (7.26T cycles/day), and around $835 for BOB (700 million cycles/day); costs are expected to decrease significantly with subsequent optimizations

· Currently, Rollups such as BOB, SOON, MegaETH are using Boundless on mainnet

Rollup has brought genuine scalability to Ethereum and the broader blockchain ecosystem. They have repeatedly demonstrated that isolating execution from the Ethereum main chain is feasible, and user experience can be continuously improved without sacrificing decentralization.

However, as more chains go live and the value carried by Rollups grows, an unavoidable question arises:

Who guarantees the security of the Rollup itself?

For a long time, Optimistic Rollup has been based on the same core assumption:

State submissions are considered valid by default, only overturned if successfully challenged.

This design is simple and elegant, but comes with obvious costs:

A challenge period of up to 7 days, complex and fragile interactive dispute processes, and high capital lock-up costs.

These issues slow down fund flows, amplify counterparty risks, and push users toward more centralized bridging solutions for faster asset turnover.

As the ecosystem matures, the direction is clear.

The next step is not to abandon Optimistic Rollup but to upgrade them.

Boundless-Enhanced Rollup Solutions

Boundless’s Rollup solution provides a direct upgrade path for OP-based Rollups toward rapid finality and Stage 2 readiness.

It is a direct upgrade on top of the Optimistic model, replacing the original interactive dispute process with ZK proofs. This is the first ZK-based non-interactive dispute resolution implemented within the OP chain ecosystem.

Boundless supports both ZK Fault Proof and Validity Proof within a unified framework.

Rollup can initially operate in ZK Fault Proof mode, significantly reducing finality time while maintaining efficiency; when faster confirmation is needed, it can switch to full Validity Proof; and it can smoothly switch between modes as requirements change.

All of this is supported by Boundless Network at the underlying layer. As the largest proof network globally, Boundless provides massive proof computing power while inheriting the decentralization and activity guarantees of the chosen settlement chain.

Flexible Security Model

Boundless offers a configurable security system that can be tailored to the specific needs of different OP Rollups:

ZK Fault Proof Mode

Uses a non-interactive ZK dispute mechanism, where disputes are resolved with a single ZK proof, eliminating the binary game process, reducing finality from 7 days to approximately 24 hours.

Validity Proof Mode

Verifies each block before final confirmation, completely removing reliance on dispute processes, achieving minute-level finality.

Teams can start with nearly zero cost using the hybrid mode, upgrade to Validity Proof when conditions are mature, and freely switch between modes as costs or business needs evolve. This flexibility allows Rollup to maintain full control over performance and costs, while preparing for the proof standards required in Stage 2.

Core Advantages of Boundless Network

Boundless Network makes proof generation truly scalable and predictable.

Massive Proof Capacity

Boundless is currently the only network employing a permissionless proof incentive mechanism, ensuring continuous online proof computing power. The network can provide 400 trillion cycles of proof capacity daily, 46 times larger than other proof networks.

Highly Competitive Proof Costs

By aggregating idle and highly optimized hardware resources, Boundless significantly reduces the marginal cost per proof. Developers do not need to build or maintain infrastructure and can achieve performance close to dedicated systems.

On Boundless, the median cost per billion cycles is only $0.04.

No New Trust Assumptions Needed

Boundless’s design centers on smart contracts, directly inheriting the security of the chosen settlement layer (such as Ethereum or Base), without adding extra trust assumptions.

Native Anti-Fragility Design

Boundless is composed of independent provers and verifiers from multiple chains, without reliance on any centralized nodes. Even under network congestion or attack, the system remains stable. The entire market operation does not depend on the core team running any critical infrastructure.

These features make Boundless the only network capable of meeting the combined demands of high-performance proof capabilities, cost efficiency, and stability for modern Rollups. Its overall performance surpasses that of self-built solutions or more centralized proof networks.

Making ZK Rollup Truly Practical

For a long time, the high cost of ZK proofs has been a core bottleneck limiting large-scale application, but Boundless is changing that.

By integrating Rollup with Boundless Network, proof costs are drastically reduced, making large-scale Validity Proofs on mainnet a feasible reality.

With current throughput levels, Boundless can provide about $29,000 worth of proof services per month for OP mainnet (24.34 trillion cycles/day), approximately $8,700 for Unichain (7.26 trillion cycles/day), and around $835 for BOB (700 million cycles/day). These figures demonstrate that Boundless can efficiently and stably scale across different Rollup sizes.

Currently, the median proof cost per billion cycles on Boundless is $0.04.

Proven in Real Networks

Boundless’s Rollup solution is not just conceptual; it is already operational on real networks.

· BOB is building a hybrid Rollup that introduces programmability into the Bitcoin ecosystem, allowing developers to inherit Bitcoin’s security while enjoying the flexibility of Ethereum smart contracts.

· MegaETH is a next-generation high-performance Rollup aimed at real-time applications, continuously challenging throughput and latency limits. SOON is a SVM-based Rollup system designed to bring Solana-level performance to more ecosystems.

All these projects rely on Boundless, replacing the original interactive dispute process with ZK mechanisms, significantly shortening withdrawal waiting times.

“The cost of interactive proofs is high, the structure is fragile, and they are easily abused. [Boundless] eliminates the risk of malicious blocking and ensures dispute resolution is both efficient and scalable.” — MegaETH Team

Building the Future for Your Rollup

Whether it’s OP architecture or customized Rollup designs, Boundless provides a universal foundation for scalable proof-based infrastructure.

Boundless’s Rollup solution enables every team to use ZK proofs to secure their own chain, advancing Rollup from “optimistic proofs” to “verifiable security,” achieving faster finality while gaining stronger security and smoother cross-ecosystem collaboration.
