Boundless is enabling truly rapid endgames for OP Rollups.

This is the first non-interactive dispute game driven by ZK proofs.

Rollups require only one smart contract to flexibly switch between ZK Fault Proof and Validity Proof modes.

• By leveraging the Boundless Network, Rollups can obtain 400 trillion cycles of proof-of-capacity computing power per day, with a median cost of less than $0.04 per billion cycles.

Based on current throughput, Boundless can provide approximately $29,000 worth of proof services per month for the OP Mainnet (24.34T cycles/day), approximately $8,700 for Unichain (7.26 trillion cycles/day), and approximately $835 for BOB (700 billion cycles/day); as subsequent optimizations are rolled out, costs will decrease significantly.

Currently, rollups such as BOB, SOON, and MegaETH are using Boundless on the mainnet.

Rollups bring true scalability to Ethereum and the wider blockchain ecosystem. They have repeatedly demonstrated that it is feasible to decouple execution from the Ethereum mainnet, and that the user experience can be continuously improved without sacrificing decentralization.

However, as more and more blockchains go live, the value carried by Rollups continues to grow, and one issue begins to become unavoidable:

Who is responsible for ensuring the safety of the rollup itself?

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

A state commit is considered valid by default and is only overturned if it is successfully challenged.

This design is simple and elegant, but the cost is equally obvious:

The challenge period lasts up to 7 days, the process is complex and fragile, and the cost of capital tied up is high.

These issues have slowed down cash flow, amplified counterparty risk, and forced users to turn to more centralized bridging solutions in exchange for faster asset turnover.

As the ecosystem matures, the direction has become very clear.

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

Rollups solution powered by Boundless

Boundless's Rollup solution provides OP-based Rollups with a direct upgrade path to rapid endgame and Stage 2 readiness.

It is a direct upgrade to the Optimistic model, replacing the original interactive dispute resolution process with ZooKeeper (ZK). This is the first non-interactive dispute resolution solution based on ZK to be implemented in the OP chain system.

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

Rollup can initially run in ZK Fault Proof mode, significantly shortening the finality time while maintaining efficiency; when faster confirmation is needed, full Validity Proof can be enabled; and it can smoothly switch between the two modes as requirements change.

All of this is supported by the underlying Boundless Network. As the world's largest proof network, Boundless provides Rollups with massive proof computing power while inheriting the decentralized nature and liveness guarantee of the selected settlement chain.

Flexible security model

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

ZK Fault Proof Mode

Employing a non-interactive ZK dispute mechanism, disputes can be resolved with just one ZK proof, completely eliminating the binary game process and reducing finality from 7 days to approximately 24 hours.

Validity Proof Pattern

Each block is verified before final confirmation, eliminating reliance on dispute resolution processes and achieving minute-level finality.

Teams can start with a hybrid mode at virtually no cost, upgrade to Validity Proof when conditions are right, and even switch freely between the two modes as cost structures or business needs change. This flexibility allows Rollups to maintain full control over performance and cost while preparing in advance to meet the proof standards required for Stage 2.

The core advantages of Boundless Network

Boundless networks make proof generation truly scalable and predictable.

Large-scale proof capability

Boundless is currently the only network that employs a permissionless proof incentive mechanism, ensuring that computing power is continuously online and always available. The network currently provides 400 trillion cycles of proof capability daily, 46 times the scale of other proof networks.

Highly competitive proof costs

By aggregating idle and highly optimized hardware resources, Boundless significantly reduces the marginal cost of a single proof. Developers can achieve near-dedicated system performance without having to build or maintain their own infrastructure.

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

No need to introduce new trust assumptions

Boundless adopts a smart contract-centric design, directly inheriting the security of the settlement layer (such as Ethereum or Base) selected by the developer, rather than adding additional trust prerequisites.

Native anti-fragility design

Boundless is comprised of independent provers and validators from multiple blockchains, without relying on any centralized node. Even under network congestion or attacks, the system remains stable. The entire market operates without relying on a core team running any critical infrastructure.

These characteristics make Boundless the only network that can currently meet the comprehensive requirements of high-performance Rollups for proof capability, cost, and stability. Its overall performance is unmatched by self-built solutions or more centralized proof networks.

Making ZK Rollup a Reality

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

By integrating Rollups into the Boundless Network, proof costs are significantly reduced, making large-scale validity proofs on the mainnet a realistic and feasible option.

At its current throughput levels, Boundless can provide approximately $29,000 worth of proof services per month for the OP mainnet(24.34 trillion cycles/day), approximately $8,700 for Unichain (7.26 trillion cycles/day), and approximately $835 for BOB (700 billion cycles/day). These figures demonstrate that Boundless can achieve efficient and stable scaling across rollups of varying sizes.

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

Verified in real networks

Boundless's Rollup solution is not just a concept; it is already operational in real networks.

• BOB is building a hybrid Rollup that brings programmability to 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 designed for real-time applications, constantly pushing the limits of throughput and latency. SOON is an SVM-based Rollup system aiming to bring Solana-level performance to a wider ecosystem.

These projects all rely on Boundless, replacing the original interactive dispute process with the ZK mechanism, thereby significantly reducing withdrawal waiting time.

"Interactive proofs are costly, structurally fragile, and easily abused. [Boundless] eliminates the risk of malicious blocking and ensures that dispute resolution is both efficient and scalable." — MegaETH Team

Build your Rollup in advance

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

Boundless's Rollup solution enables each team to use ZK proofs to secure their own chain, pushing Rollups from "optimistic proofs" to "verifiable security," achieving faster finality while gaining stronger security and smoother cross-ecosystem collaboration capabilities.
