Boundless New Breakthrough: Ethereum Leverages Bitcoin to Open a New Era of ZK Verification

Boundless’s cross-chain verification system, for the first time, allows the computationally intensive zero-knowledge proofs generated by the Ethereum mainnet and Base Layer 2 networks to be finally verified and settled by the Bitcoin network.

This not only unlocks Bitcoin’s new role as a decentralized security layer but also marks a new stage in inter-blockchain collaboration—“Verifiable Computation Guarded by Bitcoin.”

Technical Integration: How Boundless Achieves Bitcoin’s Verification Role

The core of this release is an innovative “Cross-Chain Verification System.” The system aims to solve a key problem: how to make Bitcoin the ultimate arbiter of complex computations without altering its core protocol. This design is not intended to turn Bitcoin into another smart contract platform. Boundless CEO Shiv Shankar explicitly states that its philosophy is “to provide security guarantees for Ethereum-style execution using Bitcoin.”

This relies on the synergy of two core technologies. First is BitVM (Bitcoin Virtual Machine), a framework that allows complex computations to be performed off-chain and verified on-chain within Bitcoin. Second is Boundless’s own optimized ZK proof network, responsible for generating efficient, verifiable computational proofs.

By combining these, Boundless creates a technical pathway. Complex ZK proofs are generated on chains like Ethereum, with only a small but critical amount of data “anchored” into the Bitcoin blockchain, earning the Bitcoin network’s consensus endorsement for permanence and immutability.

Paradigm Shift: From Value Storage to Verifiable Security Layer

This technological breakthrough is quietly driving an evolution in Bitcoin’s positioning. The focus of the Bitcoin ecosystem is gradually shifting from pure “value storage” to “providing verification for a broader ecosystem” without changing its consensus mechanism. For booming Layer 2 rollup networks, they are always seeking a more powerful and neutral settlement layer. Bitcoin, with its indisputable decentralization and security, has become an attractive option.

Boundless’s system will initially connect Ethereum, Base, and Bitcoin, with plans to expand to more blockchains in the future. Its long-term vision is to create a “Shared Security Layer” for the entire blockchain world based on Bitcoin.

Additionally, the system has integrated Bitcoin’s native ZK Rollup project Citrea, indicating that it is not an isolated solution but actively integrated into and promoting the development of Bitcoin’s own scalability ecosystem.

Market Impact: Transaction Dynamics Under a New Narrative

Boundless’s technological progress occurs within a specific market context. According to Gate market data, BTC prices have been volatile. As of January 21, BTC is priced at $89,003.1, down 3.9% in 24 hours. In the derivatives market, Gate Exchange’s BTC/USDT perpetual contract funding rate recently was -0.0049%, indicating a short-term cautious market sentiment or some liquidation pressure.

During the same period, market hotspots have diversified. Besides gold-related asset tokens rising due to record-high spot prices, cross-chain infrastructure projects like LayerZero have also gained market attention due to major updates expected. This shows that despite overall market adjustments, “Cross-Chain Interoperability” and “Bitcoin Ecosystem Expansion” remain key narratives closely followed by market funds. Boundless’s progress is at the intersection of these two trends.

To better illustrate the changes brought by Boundless, the table below compares key differences between traditional verification models and the new Boundless model:

In-Depth Analysis: Why Bitcoin? Why Now?

Choosing Bitcoin as the ultimate verification layer is rooted in its unique attributes. Bitcoin possesses the deepest, most decentralized hashpower and consensus trust in the cryptocurrency world, providing the highest level of finality. Meanwhile, the current blockchain development has also created new demands. With the explosion of Layer 2 and application chains, “settlement layer wars” are intensifying.

Ecosystems are seeking a foundational layer that combines high security and neutrality. Bitcoin’s purity (focused on value transfer and security) makes it a perfect, conflict-free “judge.” From a technical maturity perspective, ZK proof technology has now reached production-grade usability, becoming faster, cheaper, and more reliable. The proposals and implementations of Bitcoin extension solutions like BitVM provide feasible technical bridges to realize this vision.

Therefore, Boundless’s solution is a product of technological evolution and market demand. It is not about rebuilding smart contracts on Bitcoin but about extending Bitcoin’s ultimate trust output to the entire digital world, providing notarization for all computations requiring the highest level of verifiable certainty.

Future Outlook: The Foundation of Verifiable Trust

Boundless’s vision goes beyond mere technical integration. As its name “Boundless” suggests, it aims to establish a universal verification infrastructure. Its team believes that blockchain evolution has entered a third stage—“Verifiable Trust”—beyond Bitcoin’s “Consensus Trust” and Ethereum’s “Code Trust.” In this stage, trust no longer relies on blind faith in an institution or code but is based on cryptographic proof verifiability. Boundless aims to enable any complex computation—whether from blockchain, artificial intelligence, or other fields—to be accompanied by a proof that can be efficiently verified.

This attempt to transform trust “from a social attribute to a computable and verifiable property” could bring profound changes to the digital society. For traders and ecosystem participants, this means that in the future, evaluating a project or asset may shift from “who endorses it” to “whether its core computation has been verified by a trusted layer like the Bitcoin network.”

Bitcoin’s price on Gate is steady at $89,471.4, with a 24-hour market share of 56.42%, demonstrating that digital gold remains resilient amid volatility. Meanwhile, Ethereum fluctuates around $2,979.77. The new bridge built by Boundless is quietly connecting the eternal security of Bitcoin with Ethereum’s limitless programmability.

The narrative in the crypto world is no longer an either/or choice. As Shiv Shankar states, this is not about turning Bitcoin into Ethereum, but about enabling Ethereum-style execution to be silently and firmly guarded by Bitcoin’s hashpower forest.
