As a relatively new Layer 2 chain, Zircuit is naturally suitable for the integration of AI elements such as AI model inference and AI agents.

Binance Alpha announced the launch of Zircuit on June 3, 2025. In fact, it has been over seven months since the ZRC token went live, and Zircuit, which had faded from view for a long time, has once again become a market hotspot. Let’s take a look at what innovations Zircuit has compared to other L2 projects through this article.
This article was first published on November 26, 2024.
Why is @ZircuitL2 considered a unique layer 2? 1) It is built on the OP Stack Codebase but does not belong to the OP Superchain camp? 2) It is an OP-Rollup chain but does not highlight fraud proofs, and both its name and technical details bear a strong ZK imprint? 3) It has no connection to the AVS security consensus mechanism yet airdropped to $Eigen stakers, etc. Next, I will briefly share my understanding of the Zircuit chain:
1) The OP Stack clearly provides a foundational technical framework for quickly launching layer 2, but many chains, including Metis, Mantle, and Zircuit, have used the OP Stack Codebase technology framework without integrating into the Superchain strategic route.
The reason is simple: while the Superchain enjoys resource benefits from the OP Super Alliance, it also faces limitations in technical autonomy and flexibility, such as fraud proofs. Many layer 2s in the OP Stack camp have yet to fully launch their Fraud Proof systems, which is closely related to their choice of framework dependency over autonomous development.
Zircuit is a typical example; although marked as OP-Rollup Type on L2beat, its overall technical architecture and brand tone give a strong ZK perception impression, leading many to categorize it within the ZK-Rollup domain.
The preference for ZK technology frameworks mainly stems from the fact that ZK technology can make the OP-Rollup framework more reliable. After all, an OP-Rollup without a functioning Fraud Proof is hard to call a secure and reliable chain. However, with a ZK Proof system, the trust environment for state changes built on ZK technology can effectively compensate for its shortcomings in optimistic challenge proofs. Therefore, strictly speaking, it should be classified as a hybrid Rollup.
In fact, this type of hybrid Rollup architecture design is not new. The emerging layer 2 @MetisL2 also focuses on differentiation based on this, providing users with a fast withdrawal channel through the ZK-Rollup Router without having to wait for a 7-day challenge period.
2) Recently, Vitalik praised Starknet for its performance in optimizing the Blob Gas pricing mechanism and block state compression. This is actually another optimization direction that layer 2 needs to enhance cross-chain interoperability: improving its data structure and performance handling details.
As Ethereum's mainnet future upgrade path trends towards lightweight ZK-SNARKs, if layer 2 chains can proficiently apply ZK technology at the foundational level, enhancing performance in aspects such as data structure, state compression, and message passing, they will be closer to the future Rollup-Centric strategic direction.
Thus, as a rising star, Zircuit has made many technical optimizations in detail since its launch, such as:
- Enhanced Sequencer-level security (SLS): Many layer 2 chains face issues such as Sequencer centralization and MEV, which have hindered the stable development of financial applications like DeFi in the layer 2 environment.
In response, Zircuit has innovatively designed a preventive security architecture for the Sequencer. When transactions are in the Mempool, malicious transaction monitoring is conducted, and malicious transactions are isolated with a layer that includes multiple release conditions to ensure normal transactions are executed smoothly and securely. This method of adding a layer of security pre-check in the Sequencer component can identify potential MEV behavior, providing a fairer execution environment for DeFi applications.
- Modular Proof system: Compared to OP-Rollup chains, ZK-Rollup paradigm layer 2 chains have a clear finality advantage, but they also incur additional costs for computing, generating, and verifying proofs. This cost is not reduced by the mainnet through Blobs blocks, so ZK-Rollup layer 2 needs to find ways to lower ZK Proof costs.
To address this, Zircuit employs two paths to optimize costs: Template Proofs and Proof Aggregation. Template proofs are a transitional solution that uses simplified proof templates to maintain the verification of basic state updates without generating complete proofs for each batch to reduce costs. Proof aggregation collects multiple unverified proof tasks and generates proofs in parallel through specific circuits and general circuits, ultimately aggregating these proofs into a single proof for unified verification.
Clearly, this setup of specific proprietary circuits to adapt to different proof types can significantly reduce the costs of ZK proof generation and verification. This is similar to Starknet's use of the STARK system and zkSync's use of recursive systems, which can effectively lower ZK expenses.
- AI-Enabled layer 2: As a newer layer 2 chain, Zircuit is naturally suitable for the integration of AI elements such as AI model inference and AI agents. This is reflected in the SLS sequencer's AI model analyzing suspicious transactions and automating the isolation or suspension of protocols in special cases.
That's all.
As for why Zircuit is collaborating with @Eigenlayer for an airdrop, it is difficult to see anything purely from a technical perspective. I prefer to understand it as Zircuit's strategic support for Eigenlayer's output of Ethereum AVS security.
From a broader perspective, AVS, as a fast security consensus infrastructure, may help Zircuit's SSL system quickly integrate into other layer 2 ecosystems at some point.
