Boundless has introduced a system that lets zero-knowledge proofs generated on Ethereum and Base get verified and finalized on Bitcoin. The idea is simple enough on the surface: let other chains do the work, then use Bitcoin as the place where everything gets locked in. It’s a new twist on how blockchains might interact, with Bitcoin stepping in as the final record keeper.
Turning Proofs Into Bitcoin Anchors
The process starts with proofs being created on Ethereum or Base, where the computations and logic play out.

Once those are complete, the proofs make their way to Bitcoin, where they get settled permanently. This makes Bitcoin the last stop in the verification chain, acting like a stamp of approval that can’t be undone.
BitVM Handles the Heavy Lifting
To actually make this function, Boundless is using a tool called BitVM. It’s a framework that allows Bitcoin to check proofs without needing to change its rules or add new features.
By using BitVM alongside Boundless’ own infrastructure, the system can verify these proofs and store them on Bitcoin in a way that’s permanent and tamper-resistant.

What These Proofs Actually Do
Zero-knowledge proofs let you confirm that something is true without giving away all the details. In this case, they show that a state change or result from another chain is legit, but without dragging all the data over to Bitcoin. It means developers can prove something happened on Ethereum or Base and have Bitcoin store that outcome as a verified fact.
Giving Developers a New Tool
For people building across chains, this could be a useful new option. Instead of relying only on the original chain for verification, they can now rely on Bitcoin to seal the proof. That could make cross-chain applications feel more secure, since Bitcoin’s ledger is considered one of the hardest to tamper with.
Keeping Bitcoin Simple
Boundless made it clear that they aren’t trying to turn Bitcoin into a smart contract platform. The goal isn’t to make Bitcoin handle complex apps; it’s to let it play the role of final verifier. It’s a way to tap into Bitcoin’s stability without asking it to do too much.
Citrea Joins the Mix
Boundless is also working with Citrea, a Bitcoin-based rollup that uses zero-knowledge proofs. Those proofs will also be finalized on Bitcoin using the same process. The hope is that more systems like Citrea will join in and make use of Bitcoin as their settlement base, broadening the reach of this new setup.

Could Change How Chains Trust Each Other
This idea could lead to a bigger rethink around cross-chain security. If more networks start pushing their proofs to Bitcoin for final settlement, it could shift how trust works across blockchains. Developers might not need to rely on as many middle steps or custom bridges if Bitcoin becomes the neutral ground for proof verification.
Next Up for Boundless
The company isn’t stopping with Ethereum and Base. They plan to open the system up to other networks, too, so more chains can use Bitcoin to lock in their proofs. If that happens, Bitcoin might end up playing a much bigger role in how blockchains verify and connect.
