Empowering Q Governance Across Chains

The future of Web3 is undeniably cross-chain, with protocols and communities spanning diverse ecosystems and layers. Recognizing the pivotal role of cross-chain governance in this evolving landscape, Q Development AG, a company headquartered in Liechtenstein which supports the Q Protocol, is thrilled to announce the deployment of Hyperlane on Q. 

Hyperlane, founded in 2022, is the first permissionless interoperability framework built for the modular blockchain stack. Backed by leading crypto investors, Hyperlane is revolutionizing cross-chain connectivity. The company’s messaging bridge has been deployed on Q, facilitating seamless interoperability across Hyperlane’s expansive network of over 50 ecosystems and blockchain networks.

The first blockchain that has been integrated is Polygon PoS, one of the most used protocols in the world. The network has tens of thousands of dApps, more than 3 million average daily transactions, $5 billion in secured assets, and some of the top brands building on it.

The collaboration marks a significant milestone for Q in creating a fundamental governance layer for Web3. 

Enabling cross-chain governance on Q with Hyperlane 

Hyperlane serves as an interoperability framework within the modular blockchain stack. It functions as an Arbitrary Messaging Bridge (AMB), enabling the seamless exchange of interchain messages across many chains within the Web3 ecosystem. 

Q provides a novel key primitive for Web3: Shared Governance Security. Projects using Q’s governance opt-in features can safeguard critical governance decisions. This opens a new design space for developers, increases projects’ security, and helps them become truly decentralized.   

Up until now, Q’s decentralized governance features were only available to projects building natively on Q. Embracing the modular blockchain thesis, cross-chain governance functionality is a critical step on the development roadmap for Q. The goal is to enable all projects to tap into Q’s governance security features, no matter on which chains they are.  

Deploying and connecting to Hyperlane is an important step towards making this vision a reality. “Enabling cross-chain governance on Q is a game-changer. Our vision is to create value for all of Web3, and the way to do this is to make Q’s decentralized governance security available to all Web3 projects—no matter which chain they build on, “ says Nicolas Biagosch, co-initiator of the Q Protocol. 

“Cross-chain governance is a critical challenge facing every project that operates across multiple blockchains,” said Jon Kol, Founder of Hyperlane. “By deploying the Hyperlane interoperability framework, Q can now extend its powerful governance capabilities to any blockchain connected to the Hyperlane network – starting with Polygon PoS. And the best part? Hyperlane’s permissionless architecture meant Q could integrate and host this solution on its own. This is  an excellent example of what builders can achieve with truly open, permissionless interoperability tools.”

What does this mean for blockchain projects on Q? 

Hyperlane will empower projects on Q to go cross-chain, allowing them to leverage Q’s unique governance features while benefiting from the user base and liquidity on other chains. For example, a DAO could have its home for governance on the Q blockchain, but its treasury on another chain, with direct access DEXs, CEXs and other infrastructure components.  

Furthermore, the vision extends to enabling communities native on other chains to tap into the governance features on Q. This means that existing projects can benefit from Q’s unique offering without a full-scope deployment on Q.  

The goal is to create a seamless experience for projects and users. In the spirit of modularity, projects can get the best of all worlds by choosing which chain is best suited for each component of their operations.  

How can you use Hyperlane on Q today? 

Hyperlane’s architecture is fully permissionless, allowing anyone to deploy interoperability and bridging to their chains. Users can send messages to the designated mailbox, specifying the target chain. These messages are then verified by Hyperlane validators on Q and, upon verification, relayed to the target chain for execution. 

We are excited to announce that Polygon PoS is the first chain supported by the initial relayer. Users can already utilize the deployed infrastructure to send messages between Q and Polygon PoS without requiring any permissions.  

Moreover, the community is encouraged to contribute by funding the relayer to facilitate support for additional chains. Additionally, individuals can integrate new validators or even their own relayers into the existing infrastructure to support their applications across any chain. You can find a deployment guide on how to add Hyperlane to a chain of your choice here. 

Next steps 

The deployment of Hyperlane to the Q blockchain marks a significant milestone in the journey towards enabling seamless and secure cross-chain governance in web3. We invite the entire community to join us in this endeavor as we pave the way for a more interconnected and secure decentralized future. 

Stay tuned for further updates and developments as we embark on this exciting journey together.
