Summary: This article highlights Lumoz’s breakthrough in combining OP Stack and ZK Proof to enhance performance and security. The new zk-proposer simplifies integration, reduces maintenance, and ensures network stability. This upgrade synchronizes on-chain data and proofs, optimizes contracts, and eliminates vulnerabilities. Lumoz’s innovations reduce verification latency and cost, enable seamless migration from OP-Stack to zk-Verifier, and strengthen its leadership in blockchain scalability.
Lumoz is driving blockchain scalability by optimizing the integration of OP Stack and ZK technology. Its latest solution combines the flexibility of OP with the robust security of ZK, speeding up network validation while increasing compatibility with Ethereum and other blockchains.
In addition to providing computing power to this architecture, Lumoz also introduces innovative optimizations that simplify the integration of ZK-Fraud Proof, making the technology more efficient, secure, and easier to maintain.
The OP Stack’s integration with ZK changes the anti-fraud verification process, which was originally based on OP Stack’s optimistic consensus, by replacing the interactive fraud challenge with a non-interactive ZK proof. In the OP Stack + ZK solution, the roles of op-batcher and op-proposer remain the same, sending transactional data and state routes from the rollup to layer 1. What’s new is the introduction of the ZK Fraud Proof module. Perform rollup status and data in real time.
If necessary, a corresponding proof can be generated and sent to layer 1 for verification, significantly reducing the time required for validation. However, this enhanced architecture is more complex and requires professional maintenance of ZK-Verifier nodes by participants to ensure proper operation.
Lumoz’s latest optimization improves on the original architecture by integrating the entire ZK-Fraud Proof module into the op-proposer component and upgrading it to zk-proposer. This greatly reduces the complexity of node maintenance. In the new design, zk-proposer maintains the original functionality while adding ZK interaction options.
This option allows proposers to request the generation of proofs from the computational network layer based on the results of on-chain data execution and send the generated proofs to the chain for validation.
As shown in the diagram, this design allows any OP-Stack full node to leverage native OP-Stack components to quickly convert to a zk-Verifier node without incurring additional maintenance costs for network verification. It allows you to participate in the process. Additionally, the Layer 1 contract protocol remains unchanged, allowing existing zk-Verifier nodes to continue providing verification services, ensuring network continuity and stability.
The new solution also optimizes the validation contract logic to better protect consistency between contract data and off-chain state. In previous architectures, the proof process only verified layer 2 block heights, which risked a mismatch between the proof and the actual on-chain data, creating a potential security risk.
The new solution adds a check for the previous batch’s state root within the contract’s validation logic to ensure that each proof is generated based on the correct latest state root. This design closely links the proof generation and verification process with the real-time state of on-chain data, greatly enhancing the security and reliability of the network.
As shown in the figure, after each batch is sent on-chain, the proposer records the corresponding state routes of the batch in a specific array sequentially. Whenever a proof needs to be submitted for validation of a contract, the proposer simultaneously provides state roots for both the corresponding batch and the previous batch to the contract. Only after verifying the continuity of the state root does the Verifier contract continue verifying the proof.
Lumoz is also exploring further possibilities to integrate the OP stack with ZK technology. In the current design, network trust relies on optimistic assumptions. In other words, the security of the network relies heavily on challengers continually verifying and challenging transactions to confirm their validity. Compared to ZK-Rollups, which uses validity proofs, there is still room to improve the security.
With this in mind, Lumoz conducts experiments that simulate correct state transitions within validation nodes and provide ZK-based validity proofs at each state change interval. Similar to ZK-Rollups, these proofs serve as direct proof of state validity on-chain, eliminating the need for interactive challenges by external participants. This approach allows networks to significantly increase overall security with minimal computational cost and with few changes to existing service architectures.
Combining OP Stack and ZK, Lumoz’s optimized architecture represents a significant advance in blockchain innovation, delivering the perfect balance of speed, security, and simplicity.
By replacing traditional challenge mechanisms with non-interactive ZK proofs, Lumoz has achieved faster and more reliable transaction verification and a seamless verification process. In addition to enhanced scalability, the network trust model is also improved, reducing reliance on interactive challenges and paving the way for more efficient and proactive security solutions in the future.
