The modular computing layer Lumoz will support Op Stack + ZK Fraud Proof, opening a new model for L2 architecture

After completing tens of millions of dollars in financing, the modular compute layer Lumoz continues to make strides in the L2 track. This week, Lumoz announced that its Modular Compute Layer will support the Op Stack + ZK Fraud Proof Layer 2 architecture, opening a new mode for L2 architecture.

Modular Compute Layer will Support Op Stack + ZK Fraud Proof

The Op Stack + ZK Fraud Proof architecture is a new design that integrates validity proofs based on zero-knowledge proofs into Optimistic Rollup technology. When a challenger points out that the sequencer has submitted incorrect data, they will submit a challenge to L1. The sequencer must generate the corresponding ZK Proof within a limited challenge time and submit it to the Layer 1 contract for verification. If the verification result indicates that the data is valid, the challenge fails; otherwise, the challenge succeeds.

This illustration shows the specific processing flow of fraud proofs in Layer 2 technology under the Op Stack and ZK Fraud Proof architecture. In this architecture, the Op Stack module undertakes the core functions of Layer 2, including handling the basic functions of the Layer 2 blockchain and the responsibility of submitting batches to Layer 1. Meanwhile, the ZK Fraud Proof module focuses on handling challenges to fraud proofs.

The process details are as follows:

1. Challenge Initiation: The validator initiates a challenge for fraud proof.
2. Information Synchronization: Lumoz verification nodes synchronize challenge information to prepare for the next verification work.
3. Obtaining Zero-Knowledge Proof Inputs: The verification nodes obtain the necessary zero-knowledge proof input data from the Op Stack module, including block trace, batch info, etc.
4. Generating Zero-Knowledge Proof: Lumoz will then send a request to the modular compute layer to generate the required zero-knowledge proof.
5. Proof Submission: Once the zero-knowledge proof is generated, the Lumoz verification node will submit the proof to Layer 1 for verification.

Through the above process, the challenge and verification process of ZK Fraud Proof is completed.

As is well known, Optimistic Rollup has lower costs but longer withdrawal waiting times; while ZK Rollup has almost no waiting time for withdrawals but requires higher costs. This solution combines the advantages and disadvantages of Optimistic Rollup and ZK Rollup, maintaining low costs while effectively shortening waiting times.

Modular Compute Layer

Lumoz provides a modular compute layer that can offer stable and reliable computing power support for the Op Stack + ZK Fraud Proof architecture blockchain. When Layer 2 submits batch data, if there is a challenger initiating a challenge, the modular compute layer will rely on computing power services to generate the corresponding proof data. This process requires the computing power service of the modular compute layer to submit the correct proof within the specified time, which will be considered a failure for the challenger; otherwise, it will be deemed a success for the challenger.

The role of Lumoz's modular compute layer in the Op Stack + ZK Fraud Proof architecture:

In summary, the Lumoz ZK Prover Network provides a high-performance modular compute layer for the Optimistic + ZK Fraud Proof architecture through decentralized miner participation in ZKP computation, rich circuit support, and a complete proof verification process. Coupled with Lumoz's trustless native cross-Rollup communication technology, it not only securely shares liquidity among all Rollups but also provides strong multi-Rollup interoperability, opening up new possibilities for decentralized applications and DeFi protocols.

Conclusion

Lumoz's Modular Compute Layer, supported by Optimistic Rollup + ZK Fraud Proof, has created a new Layer 2 architecture model. This solution fills the gap in the current market for ZK and OP hybrid solutions, achieving effective technical integration. By combining the advantages of Optimistic Rollup and ZK Rollup, we can significantly reduce costs while shortening verification waiting times. As a pioneer in this field, Lumoz will continue to leverage its strengths and optimize technical solutions. Meanwhile, we hope more people will pay attention to and contribute to the development of this hybrid architecture of Optimistic Rollup and ZK Fraud Proof, contributing to the industry's growth!
