Author: DeMan

Recently, an important cooperation project has started in the crypto circle, with Polyhedra Network and Nubit as the partners. Among them, Polyhedra Network has completed a financing of 20 million US dollars, and Nubit will also focus on ZKP proof. The following is a detailed introduction to the cooperation.

Polyhedra and Nubit are worthy of attention, with core advantages in the fields of Bitcoin public chain and ZKP technology respectively

First, let’s introduce these two major partners respectively.

As a pioneer in blockchain technology, Polyhedra 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 designed to provide efficient and trust-minimized solutions for asset transfers, messaging, and data sharing between various Web2 and Web3 systems. Polyhedra's team consists of top engineers, developers, and researchers from UC Berkeley, Tsinghua University, and Stanford University, who focus on developing a full-stack Web3 solution suite based on ZKP, including but not limited to zkSNARKs, zkBridge, and zkDID (decentralized identity) solutions. In addition, Polyhedra has also made breakthroughs in promoting the security of cross-chain bridging protocols, significantly reducing the security risks of cross-chain transactions and bringing reliability improvements to the entire blockchain ecosystem.

Nubit is an iconic Bitcoin native project that focuses on the expansion of the data availability layer. As the first Bitcoin native data availability layer, Nubit fully leverages Bitcoin's security framework and provides unparalleled data processing capabilities to the Bitcoin community. Nubit's technology expands Bitcoin's data capacity, supporting not only Ordinals, Bitcoin's second-layer solutions such as Lightning Network, but also providing the necessary data support for key applications such as price oracles and indexers. Through its high-performance consensus algorithm, Nubit inherits Bitcoin's fully censorship-resistant characteristics, ensuring the transparency and decentralization of the system, while significantly improving the scope and efficiency of the Bitcoin ecosystem.

The two sides have cooperated in the fields of technology and ecology, and the interaction between the two sides has attracted attention from various industries

At the forefront of blockchain technology, Polyhedra Network is continuously advancing the interoperability, scalability and privacy protection of Web3 through its advanced zero-knowledge proof protocol - zkBridge.

Recently, Polyhedra Network successfully raised $20 million in a strategic financing led by Polychain Capital, with the company's valuation reaching a staggering $1 billion. This round of financing also attracted the participation of 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 in the past two years.

Following this, in April, Nubit, the Bitcoin native data availability layer project, announced a partnership with Polyhedra Network. The two parties will jointly develop a verification system tailored for the Bitcoin ecosystem. By forwarding the commitments of the on-chain light client to Nubit's data root, this approach enables high-throughput data availability solutions to be seamlessly integrated into the second-layer contracts. This innovation ensures the security of Bitcoin's second-layer network and the high availability of data, providing support for developers to build scalable and reliable infrastructure and applications on Bitcoin.

In addition, Nubit and Polyhedra Network are also committed to implementing ZKP-based state proofs for Bitcoin meta-protocols such as Ordinals, BRC-20, and Atomicals. Using ZKP to verify the state transition function of the meta-protocol and combining it with Nubit's modular indexer can achieve completely trustless index result proofs, thereby promoting modular interoperability of Bitcoin meta-protocols. This collaboration demonstrates Polyhedra Network's core technical strength and market leadership in promoting secure and scalable solutions for the blockchain ecosystem.

Interpreting the deep linkage between the two parties from a technical perspective, more future strategic development ideas gradually emerge

The cooperation between Polyhedra Network and Nubit marks an important step towards improving the functionality and scalability of the Bitcoin ecosystem. Nubit, as the first Bitcoin native data availability (DA) layer, is focused on building a decentralized and interoperable future. By leveraging Polyhedra's expertise in advanced cryptography, this collaboration aims to promote innovation and cultivate a more secure, scalable and interoperable Bitcoin ecosystem.

In accelerating Web3 adoption, Polyhedra Network is turning the innovative ideas of individuals and organizations into reality by breaking the limitations of traditional computing power and leveraging the exponential computing power provided by zero-knowledge technology. The cryptography experts on its team have developed a series of cutting-edge ZK algorithms that are secure, fast and widely compatible. These innovations not only accelerate the development of Web3, but also make it cheaper and inherently more secure.

In addition, Nubit is focused on enhancing data availability capabilities within the Bitcoin ecosystem. Nubit and Polyhedra Network will work together to develop a set of powerful DA proof systems tailored for the Bitcoin ecosystem. By forwarding commitments to Nubit's data root in an on-chain light client, developers can seamlessly integrate high-throughput DA solutions into second-layer contracts. This integration ensures the security and data availability of Bitcoin's second-layer network, enabling developers to build scalable and reliable infrastructure and applications on Bitcoin.

Nubit and Polyhedra are also working on implementing ZKP-based state proofs for Bitcoin meta-protocols such as Ordinals, BRC-20, and Atomicals. Using ZKP to verify the state transition function of the meta-protocol, combined with Nubit's modular indexer, a fully trustless index result proof is achieved, thereby achieving modular interoperability of the Bitcoin meta-protocol. This progress enables users to independently verify these results, enhancing the decentralization and integrity of the Bitcoin ecosystem.

Innovations in zk-SNARK-based signature aggregation protocols, the collaboration will also explore the integration of single-slot final consensus into Nubit. This integration marks a major advancement in traditional blockchain consensus mechanisms, and through Polyhedra Network's unique innovations, it can minimize communication overhead between validators, enabling Nubit to expand its consensus validator set to hundreds of thousands, significantly improving the decentralization of the Bitcoin DA system.

In addition, Polyhedra Network will facilitate trustless cross-chain interoperability from Bitcoin to Nubit through its zkBridge, enabling seamless interoperability between the Bitcoin and Nubit ecosystems. This cross-chain integration opens up new opportunities for using BTC within Nubit, including staking and other services, in line with Nubit’s commitment to expanding Bitcoin’s utility and accessibility.

By combining Nubit’s Bitcoin-native DA solution and modular indexer with Polyhedra’s expertise in ZKPs, consensus algorithms, and cross-chain interoperability, Nubit and Polyhedra are working together to drive modular transformation within the Bitcoin ecosystem, unlocking new possibilities for Bitcoin’s utility and adoption.
