As blockchain networks continue to flourish, they inherently foster specialization and diversity, resulting in many separate blockchain networks, each with its unique attributes and use cases. While this diversification brings immense benefits, it has also given rise to the need for seamless interoperability between these networks.

This is where the collaboration between Manta Network and Polyhedra Network comes into play.The strategic partnership will bring trustless and efficient interoperability to Manta network ecosystem by using zkBridge. The teams will work together to enable the fast finality between Manta Pacific and other blockchain networks and empower zkSBT with cross-chain interoperability.

This article explores why zkBridge, Fast Finality for Manta Pacific, and Cross-Chain zkSBT are so important. These three aspects form the foundation of the partnership between Manta Network and Polyhedra Network, and they play a crucial role in the world of blockchain technology.

zkBridge: Trustless cross-chain interoperability with Zero-Knowledge Proofs

One important aspect of the Manta Network and Polyhedra collaboration is to bring zkBridge to the Manta Network ecosystem. zkBridge is a cross-chain interoperability protocol that utilizes zkSNARKs (zero-knowledge succinct non-interactive arguments of knowledge) to efficiently convince the receiver chain that a certain state transition happened on the sender chain. With zero-knowledge proofs, zkBridge offers both strong security without relying on external assumptions and a significant reduction in on-chain verification cost. At its core, zkBridge is composed of a block header relay network and an updater contract:

The block header relay network acts as an information conduit, fetching block headers from the sender chain. These headers are then subjected to zkSNARK-based proof generation, providing indisputable evidence of their validity. Once these proofs are generated, they are transmitted to the updater contract residing on the receiver chain.

The updater contract, equipped with a light-client state, performs automated verification of the proofs and adds the validated block headers to the sender chain’s current main chain. This mechanism ensures that state transitions on the sender chain are accurately and efficiently reflected on the receiver chain, paving the way for enhanced cross-chain interoperability between various layer-1 and layer-2 networks.

Enable Fast Finality for Manta Pacific

One of the primary obstacles in the realm of cross-chain interactions has been the lengthy timeframes for the cross-chain and cross-rollup interoperability from an optimistic rollup to other blockchain networks, due to the long challenge period for state finality .

Manta Pacific is a unique L2 ecosystem for EVM-native ZK applications, which provides a scalable and inexpensive gas-fee environment for ZK applications powered by OP Stack. To improve the efficiency and user-experience, we will deploy the zkBridge fast finality product for optimistic rollups to Manta Pacific. To enable the fast finality, zkBridge incorporates Lagrange State Committees, which provide a mechanism for generating zero-knowledge state proofs for optimistic rollups by using the restaked Ethereum validators on EigenLayer. Each State Committee attests to the finality of a proposed state transition from Manta Pacific to Ethereum.

Utilizing efficient zero-knowledge proof protocols, the zkBridge Fast Finality Product achieves the monumental task of proving the Ethereum Proof-of-Stake consensus and state proofs from state committees for optimistic rollups within seconds. By using the efficient proof system, deVirgo, the proving time for Ethereum full PoS can be as fast as 10 seconds per block, which is enough to catch up with the block time of Ethereum.

Cross-Chain zkSBT: Fostering Ecosystem Collaboration

A thriving blockchain ecosystem is characterized by interoperability, seamless data sharing, and collaborative efforts among diverse networks. The Manta Network-Polyhedra Network partnership recognizes the importance of this aspect and presents our implementation of Cross-Chain zkSBT powered by zero-knowledge proof technology.

This visionary technology facilitates secure, efficient, and transparent data access, sharing, and verification across multiple blockchain networks. By breaking down the barriers that have historically hindered communication and cooperation between chains, Cross-Chain zkSBT amplifies the overall functionality and efficiency of the broader blockchain ecosystem.

Concluding Remarks

In summary, the strategic partnership between Manta Network and Polyhedra Network will unlock potential applications for zkBridge interoperability on both optimistic rollups and zkSBTs. We present the integration on zkBridge fast finality product on Manta Pacific and introduce the cross-chain zkSBT, which offers secure data handling across blockchain networks, eliminating barriers and enhancing blockchain network efficiency.
