Zero Knowledge Proof (ZKP) as a more trustless, decentralized The solution to expand Ethereum in a standardized way has been widely recognized by the industry. In the cross-chain industry, it also shows advantages such as trustless facility dependence, light computing on the chain, general purpose, and low latency. In particular, ZKP's advantages in solving current cross-chain bridge security issues at the trust level are more obvious.

Multichain launches zkRouter

Multichain, as the leading cross-chain bridge and general message cross-chain service provider, has connected 81 public chains with more than 800,000 users. Multichain has achieved great success in products such as Router, anyCall and NFT Router. Today, Multichain launched a new next-generation technological innovation product - zkRouter, and released the zkRouter white paper.

As the latest solution, zkRouter uses ZKP technology to safely and efficiently connect multiple blockchain networks and realize wireless seam interoperability. This innovation is very useful for cross-chain interoperability as it allows transfer of assets and information between different blockchains in a trustless, secure and privacy-friendly manner without revealing sensitive information. At present, most cross-chain bridges still rely on centralized mechanisms to transmit cross-chain information, but ZKP can be used to eliminate this need for trust, which is the main reason why Multichain uses this mechanism to build a new generation of cross-chain interoperability protocols.

Cross-alignment based on zkRouter protocol Chain application process

Advantages of zkRouter

The advantages of zkRouter applying ZKP technology to cross-chain interoperability include:

1. Trustless

Cross-chain communication messages are proved by zk-SNARKs without introducing external trust assumptions. On the premise of the security of the external public chain and the underlying consensus, as long as there is an honest node in the relay network, the security of the zkRouter cross-chain can be guaranteed.

2. Scalability and Efficiency

zkRouter It allows more dApps to run on it, and its lightweight on-chain calculation allows a large number of transactions to run concurrently with low latency to generate proof results. At the same time, the lightweight on-chain calculation also means less Gas requirements, further reducing user cross-chain cost.

3. Low threshold and decentralization

zkRouter Node operators on the platform can participate in the verification of cross-chain transactions without pledging assets. This mechanism makes the setting of zkRouter nodes easier and more efficient, and can further enhance the degree of decentralization

Enabling cross-chain applications

zkRouter technology uses ZKP technology to synchronize the consensus of the source chain to the target chain, and there is no limit to scalability , so the cross-chain interoperability protocol built by zkRouter can be applied to many application scenarios. Developers can use zkRouter, a trustless and universal cross-chain infrastructure, to empower their applications and expand their application functions. At the same time, they can further increase their imagination in the development of blockchain ecological innovation, thereby bringing new application scenarios.

1. Asset cross-chain

Asset cross-chain bridge , is currently one of the most suitable applications for zkRouter, and it is also the scene with the most cross-chain demand. The zkRouter-based asset cross-chain trustless facility dependency can greatly reduce the possibility of cross-chain bridge security incidents and eliminate users' doubts about centralized bridges. At the same time, zkRouter has high versatility and is friendly to running or start-up cross-chain bridge projects, and supports a variety of cross-chain bridge models, such as: Mint/Burn, capital pool or a hybrid model of the two.

2. On-chain trusted oracle

zkRouter The block header of the source chain can be credibly transferred and stored to the target chain, and the information relayed through zkRouter can also be used by other existing dApps. This interaction allows other applications to determine whether a transaction (for example) happened on the source chain. Different from other off-chain information collection Oracles, the Oracle built on zkRouter will be more credible because of its zero-knowledge proof results.

3. Multi-chain contract interoperability

zkRouter It will provide a technical basis for multi-chain interoperability for the development of smart contracts, and the application can be efficiently and safely called by multiple chains. Developers do not need to be limited to the solid thinking of single-chain development, nor do they need to make trade-offs between the advantages and disadvantages of multiple chains. Developers can easily complete cross-chain contract interoperability calls just like developing contracts on the same chain. The original application can further enjoy the business expansion brought by multi-chain interoperability, such as: multi-chain issuance of blockchain games, multi-chain lending in the Defi field, etc.

4. Cross-chain Swap

Currently, the Swap application on the chain is limited to a single-chain ecosystem. Although it can be deployed on multiple chains, the assets between different chains are severely fragmented, which limits the upper limit of Swap's development. Using zkRouter can effectively solve existing problems and empower cross-chain Swap.

5. Multi-chain issuance of Token and NFT

Using zkRouter can easily mint and issue Token and NFT, and realize multi-chain deployment efficiently. This solves the accessibility and liquidity challenges faced by traditional cross-chain bridges, further improving user experience.

zkRouter progress and planning

< p>Multichain has been committed to advancing the development of cross-chain and interoperability, near the release of zkRouter, Multichain is excited to show how it will revolutionize the communication and interoperability between blockchains, and would like to share more about this Breakthrough technology information, and witness the new possibilities created by zkRouter for the blockchain.

Currently, the development team of Multichain has produced a demo version and is verifying it. At the same time, in order to enable the community to see the practical application of this technology and understand its potential application scenarios, we will soon launch a related website to explain the concept of zero-knowledge proofs and how zkRouter can use them to provide trustless and secure cross-chain messages transfer.

In addition, Multichain will release the business development plan of zkRouter, looking forward to cooperating with projects with a common vision, whether it is to build a new Whether it is an application developer, or a business looking to simplify operations, zkRouter can help them achieve their goals.

zkRouter is launched across An important step in the field of chain interoperability is a solid step towards the future of a further decentralized multi-chain universe. Multichain will continue to firmly promote the realization of trustless and decentralized interoperability, and strive to open up decentralization and interoperability. A new era of operational blockchain ecosystems.
