Introduction

In developing Boundless, we explored numerous approaches to address the diverse needs of developers, focusing on factors like cost efficiency, developer experience, censorship resistance, and reliability.

Ultimately, we determined that smart contracts, co-located with the protocols that need ZK proofs, provide the strongest foundation for developers to interact with Boundless. Leveraging ZK technology, Boundless enables major components, such as the proving node and market requests to operate off-chain while meeting stringent liveness and security requirements. Boundless offers users a seamless experience akin to using a DEX, coupled with the robust benefits of ZK-powered protocols.

Boundless is already deployed across major L1s and L2s, letting each application integrate natively on its home chain.

Boundless Market Architecture Advantages

Boundless is designed for demanding protocols such as stage 2 rollups, DEXs, restaking protocols, and onchain governance systems. Use cases like these require the censorship resistance, safety, and liveness guarantees of a major L1. Our approach to building a proof market ensures:

On-chain verification with the same security as the host chain.
Censorship resistance as strong as the host chain.
Elimination of bridging of funds.

Applications choose their chain; Boundless meets them there.

Verification Guarantees

For applications requiring the safety guarantees of a major L1, there is no substitute for ZK verification on the L1. Verification on other chains and bridging results introduce trust dependencies on additional validator sets and bridges. Boundless addresses this by requiring proof delivery and verification directly on the application’s chain for payment to be processed.

This approach ensures applications interact directly with the Boundless Market contract, eliminating intermediaries and preserving the guarantees of the chain the application chooses to settle on.

Censorship Resistance

Protocols like rollups and governance systems demand consistent proof delivery, even against adversarial efforts to obstruct it. Boundless ensures censorship resistance by leveraging the application’s chain’s transaction guarantees. As long as the application’s chain and a single prover remain operational, Boundless will deliver proofs.
