Boundless: A Universal Proof Network for Internet-Scale Blockchains

Abstract

Boundless is a universal zero-knowledge (ZK) protocol providing verifiable computation to every chain.

The Boundless Network is built upon a decentralized proving marketplace, a novel incentive mechanism for ZK proving, and a smart-contract centric design that can be deployed to any blockchain.

ZK Coin (ZKC) is Boundless’ native token with an initial supply of 1B. It is used to reward provers, secure proof delivery, support staking, and participate in governance.

What Is Boundless

Most blockchains rely on a re-execution model where every node replays every transaction to verify it. This redundancy leads to high computational costs and limited scalability. As applications become more demanding, this execution model becomes a bottleneck.

Boundless introduces a ZK-based model. Execution is performed off-chain by prover nodes, compressed into a verifiable proof, then verified onchain at a low cost. This replaces the re-execution model entirely and makes execution cheaper and easier to scale. In practice, Boundless acts as a universal ZK layer: protocols from any ecosystem can connect to the Boundless Network to access a high amount of proving capacity.

Technical Principles of Boundless

The core technology of Boundless combines a decentralized proving marketplace, a ZK rollup framework, a network-wide incentive mechanism, and support for multiple zkVMs.

Decentralized Proving Marketplace

Boundless operates a permissionless marketplace where protocols and applications submit proof requests and prover nodes fulfill them. Anyone with suitable hardware can join as a prover and contribute compute to the network. This open design allows Boundless to reach high proving capacity at low costs while staying decentralized. It reduces reliance on any single prover and helps keep strong network liveness and censorship-resistance.

ZK Rollup Framework

Boundless offers a rollup framework that gives OP stack rollups a direct path to faster finality. Today, all OP stack rollups are limited by the 7-day withdrawal period, which slows down how quickly users can move funds back to L1 or between ecosystems in a decentralized way. With Boundless, rollups can adopt ZK fraud proofs to replace the interactive dispute game with proof verification, or become a full ZK rollup directly.

Proof of Verifiable Work

Proof of Verifiable Work (PoVW) is a novel incentive mechanism introduced by Boundless that coordinates prover incentives on the network. Each proof includes a verifiable measure of compute work which determines how much provers earn in a given period. Provers must stake ZKC as collateral when they accept proof requests. If they successfully complete the proof request on time, they receive rewards proportional to their work and get their stake back. If they fail, part of the stake is slashed and burned, providing crypto economic guarantees for requestors. Since issuance is tied to real proving work, ZKC function as one of the first ZK-mined tokens.

Multi-zkVM Architecture

Boundless was designed to support multiple zero-knowledge virtual machines (zkVMs). Currently using RISC-V based zkVMs such as RISC Zero’s R0VM for high performance proving. Over time, support for other zkVMs like Airbender and SP1 will be added, giving developers flexibility to choose the prover that suits their needs while still benefitting from the capacity and economics of the Boundless Network.

Strengths of Boundless

Boundless provides a powerful ZK layer that can serve many blockchains and applications at once. The protocol integrates into current L1s and L2s rather than competing with them, creating a simple way for ecosystems to add scalable, verifiable compute. Its high capacity network processes trillions of cycles of compute per day, enough to handle demanding workloads such as proving entire blockchains like Ethereum, Base, and Optimism.

Since Boundless operates in an open market, provers are directly rewarded for being faster and more efficient than other provers. This naturally pushes the ecosystem toward better proving techniques, hardware optimization, and lower proving costs over time. As more provers join and compete, users benefit from cheaper and faster proving, shaping the future of ZK proofs everywhere.

Boundless is backed by institutional partners such as Blockchain Capital, Figment Capital, and Bain Capital Crypto, signaling strong due diligence and long-term support from established crypto investors. Their involvement helps validate the importance of ZK and supports ongoing strategic developments and ecosystem growth.

Boundless Tokenomics

ZK Coin (ZKC) is the native token of Boundless with an initial supply of 1 billion. It is used as collateral for proving, rewarding provers, staking, and as a governance token for the protocol. The initial allocation is as follows: 41.6% for ecosystem growth, 23.5% for the core team and early contributors, 8.3% for the community token sale and airdrops, 5.1% for community partner marketing, and 21.5% for private investors. New ZKC is issued over time, with inflation starting at 7% in Year 1 and tapering to 3% from year 8 onward.

ZKC plays several key roles in the Boundless Network:

Proving Collateral: Before accepting a proof request, provers must stake ZKC as collateral to secure proof delivery. If the proof isn’t submitted on time, the stake is slashed: 50% is burned permanently, and the remaining is reassigned onchain as a bounty for another prover to complete the work. This collateral system provides stronger economic guarantees of proof delivery.

Protocol Staking: Staking is the first step to participating on the Boundless Network. By staking, token holders can earn PoVW rewards by running provers, and take part in protocol governance. This incentivizes nodes to stay online and gives token holders a role in guiding the protocol’s future, whether they are actively proving or not. Because of the importance of these roles in the network, all protocol stakers earn a baseline share of 25% of each epoch’s emission.

Mining Rewards: Prover nodes are the backbone of the Boundless Network. They earn 75% of each epoch’s emission through Proof of Verifiable Work, based on the amount of verifiable work they perform. This aligns token issuance directly with useful work and incentivizes faster more efficient proving.

Powering Governance: ZKC holders participate in governance by staking their tokens. This includes voting power over marketplace mechanics, the ZKC token, zkVM additions, grants and other upgrades.

Conclusion

Boundless is a universal protocol that brings ZK proofs to every blockchain. It doesn’t compete with existing networks, it enhances them, removing the scaling limits that have held the crypto space back. By turning verifiable compute into an abundant resource that any ecosystem can tap into, Boundless makes it possible for blockchains to operate at internet-scale.
