After raising $20 million, Polyhedra Network collaborates with Nubit to strengthen the Bitcoin on-chain ecosystem

Recently, an important collaboration has begun in the crypto space, involving Polyhedra Network and Nubit. Polyhedra Network has completed a $20 million funding round, and Nubit will also focus on ZKP proofs. Below is a detailed introduction to the collaboration.

Both Polyhedra and Nubit have core advantages in the Bitcoin public chain and ZKP technology fields, making them worthy of attention

First, let's introduce these two major partners.
As a pioneer in blockchain technology, Polyhedra Network is driving innovation in Web3 interoperability, scalability, and privacy through cutting-edge zero-knowledge proof (ZKP) technology. The network has built a series of advanced infrastructures aimed at providing efficient and trust-minimized solutions for asset transfers, messaging, and data sharing between various Web2 and Web3 systems. The Polyhedra team consists of top engineers, developers, and researchers from the University of California, Berkeley, Tsinghua University, and Stanford University, focusing on developing a full-stack Web3 solution suite based on ZKP, including but not limited to zkSNARKs, zkBridge, and zkDID (decentralized identity) solutions. Additionally, Polyhedra has made breakthroughs in enhancing the security of cross-chain bridging protocols, significantly reducing the security risks of cross-chain transactions and improving the reliability of the entire blockchain ecosystem.

Nubit, on the other hand, is a flagship Bitcoin-native project focused on expanding the data availability layer. As the first Bitcoin-native data availability layer, Nubit fully leverages Bitcoin's security framework to provide unparalleled data processing capabilities for the Bitcoin community. Nubit’s technology expands Bitcoin's data capacity, supporting not only Ordinals and Bitcoin second-layer solutions like the Lightning Network but also providing essential data support for key applications such as price oracles and indexers. Through its high-performance consensus algorithm, Nubit inherits Bitcoin's complete censorship resistance, ensuring the system's transparency and decentralization while significantly enhancing the scope and efficiency of the Bitcoin ecosystem.

Collaborating in technology and ecosystem fields, the interaction points between both parties are diverse and attract industry attention

At the forefront of blockchain technology, Polyhedra Network is continuously advancing Web3 interoperability, scalability, and privacy protection through its advanced zero-knowledge proof protocol—zkBridge.
Recently, Polyhedra Network successfully raised $20 million in a strategic financing round led by Polychain Capital, achieving an astonishing valuation of $1 billion. This round of financing also attracted participation from heavyweight investors such as Animoca Brands, Emirates Consortium, Arkstream Capital, Mapleblock Capital, Hashkey Capital, UoB Ventures, Symbolic Capital, Longhash Ventures, MH Ventures, and Web3Port Foundation, marking the company's fifth financing round in the past two years.
Following this, in April, the Bitcoin-native data availability layer project Nubit announced a collaboration with Polyhedra Network. The two parties will jointly develop a verification system tailored for the Bitcoin ecosystem. By forwarding the commitments of on-chain light clients to Nubit’s data root, this method allows high-throughput data availability solutions to be seamlessly integrated into second-layer contracts. This innovation ensures the security of the Bitcoin second-layer network and the high availability of data, providing support for developers to build scalable and reliable infrastructure and applications on Bitcoin.
Furthermore, Nubit and Polyhedra Network are also committed to implementing ZKP-based state proofs for Bitcoin meta-protocols such as Ordinals, BRC-20, and Atomicals. By utilizing ZKP to verify the state transition functions of meta-protocols and combining them with Nubit’s modular indexer, it is possible to achieve completely trustless proof of indexing results, thereby promoting the modular interoperability of Bitcoin meta-protocols. This collaboration showcases Polyhedra Network's core technological strength and market leadership in advancing secure and scalable solutions for the blockchain ecosystem.

Analyzing the deep synergy between both parties from a technical perspective, more future strategic development ideas gradually emerge

The collaboration between Polyhedra Network and Nubit marks an important step towards enhancing the functionality and scalability of the Bitcoin ecosystem. Nubit, as the first Bitcoin-native data availability (DA) layer, focuses on building a decentralized and interoperable future. By leveraging Polyhedra's expertise in advanced cryptographic technology, this collaboration aims to drive innovation and cultivate a more secure, scalable, and interoperable Bitcoin ecosystem.
In accelerating Web3 adoption, Polyhedra Network is breaking traditional computational limits and utilizing the exponential computational power provided by zero-knowledge technology to turn innovative ideas from individuals and organizations into reality. The team of cryptographic experts has developed a series of secure, fast, and widely compatible cutting-edge ZK algorithms, which not only accelerate the development of Web3 but also make it more cost-effective and inherently more secure.
Additionally, Nubit focuses on enhancing data availability capabilities within the Bitcoin ecosystem. Nubit and Polyhedra Network will jointly develop a powerful DA proof system tailored for the Bitcoin ecosystem. By forwarding commitments from on-chain light clients to Nubit’s data root, developers can seamlessly integrate high-throughput DA solutions into second-layer contracts. This integration ensures the security and data availability of the Bitcoin second-layer network, enabling developers to build scalable and reliable infrastructure and applications on Bitcoin.
Nubit and Polyhedra are also committed to implementing ZKP-based state proofs for Bitcoin meta-protocols such as Ordinals, BRC-20, and Atomicals. By utilizing ZKP to verify the state transition functions of meta-protocols and combining them with Nubit’s modular indexer, it is possible to achieve completely trustless proof of indexing results, thereby realizing the modular interoperability of Bitcoin meta-protocols. This advancement allows users to independently verify these results, enhancing the decentralization and integrity of the Bitcoin ecosystem.

In terms of innovations in zk-SNARK-based signature aggregation protocols, this collaboration will also explore integrating single-slot finality consensus into Nubit. This integration marks a significant advancement in traditional blockchain consensus mechanisms, allowing Nubit to scale its consensus validator set to hundreds of thousands while minimizing communication overhead between validators through Polyhedra Network's unique innovations, significantly enhancing the decentralization of the Bitcoin DA system.
Moreover, Polyhedra Network will facilitate trustless cross-chain interoperability from Bitcoin to Nubit through its zkBridge, achieving seamless interoperability between the Bitcoin and Nubit ecosystems. This cross-chain integration provides new opportunities for using BTC within Nubit, including staking and other services, aligning with Nubit’s commitment to expanding Bitcoin's utility and accessibility.
By combining Nubit’s Bitcoin-native DA solutions and modular indexer with Polyhedra's expertise in ZKP, consensus algorithms, and cross-chain interoperability, Nubit and Polyhedra are jointly committed to driving modular transformation within the Bitcoin ecosystem, unlocking new possibilities for Bitcoin's utility and adoption.
