Marlin Brief Review: Does It Consume All Popular Narratives Including MEV, Oracle, ZK?
Marlin is a decentralized distributed node network system supporting TEE and ZK.
Navigating Web3 tides with focused insightsAuthor: Haotian
What should we make of @MarlinProtocol, which appears to be sweeping across popular narratives like MEV, Oracles, ZK, and even AI? This cycle has seen many old projects rejuvenated, and Marlin initially positioned itself as providing upstream "decentralized node enhancement services." The new AVS (Actively Validated Services) narrative on Ethereum tells us that when operational capabilities of blockchain nodes are "commoditized" and packaged, numerous new use cases emerge. Here are some of my observations:
1) The essence of commoditizing the Ethereum AVS node network lies in enhancing the capabilities of Ethereum Validators Operators. As such, AVS can support various extended services including decentralized Oracles and Sequencers. Marlin officially positions itself as a trusted coprocessor leveraging technologies like TEE (Trusted Execution Environment) and ZK (Zero-Knowledge Proofs), offering developers decentralized computing solutions via SDKs and APIs.
In simple terms: Marlin is a decentralized distributed node network supporting TEE and ZK, capable of providing network resources such as node computing power and storage for applications including Oracle systems, ZK provers, and AI.
Since Marlin's core technology revolves around a trusted, high-performance node network with broad service capacity, it can package various services through SDKs and APIs for external delivery. The scope of the node’s operational services essentially defines its business coverage.
2) What kinds of service scenarios can it expand into? Marlin outlined several directions in a tweet introducing its Oyster network service:
1. Secure ZK proof generation: Using the Oyster system, ZK applications and users can delegate proof generation tasks to Marlin's secure enclaves. Marlin’s distributed nodes come equipped with TEE execution environments, enabling isolated enclave spaces within which ZK proofs can be generated securely;
2. Web3 gateway: Serving as a secure bridge from Web2 to Web3, it provides traditional Web2 applications with a reliable entry point to Web3, lowering user barriers and addressing limitations inherent in browsers—such as storage, RPC interfaces, indexers, relaying services, identity authentication, and authorization;
3. Decentralized frontends: Offering decentralized frontend services based on distributed storage for Web3 apps, avoiding service outages caused by centralized cloud providers like AWS going down, thereby ensuring uninterrupted product functionality;
4. Oracles: The Oyster network’s distributed nodes can aggregate data from multiple oracle sources and rapidly compute and update price information using the secure enclave environment within each node, delivering competitive oracle services;
5. Decentralized AI: As large-scale AI model training becomes increasingly critical, the TEE-based trusted coprocessor can provide secure and privacy-preserving environments for AI model training. It also enables building a decentralized, transparent, and verifiable incentive framework, transforming the distributed node network into a decentralized cloud computing “leasing” service network;
3) Clearly, Marlin’s enhanced distributed node infrastructure supports a wide range of applications—largely due to its high technical entry barrier during network construction:
On one hand, every node is equipped with TEE. Having TEE implies strong hardware performance and allows creation of a secure, isolated enclave environment within the storage system, complete with robust privacy protection and access control mechanisms to ensure data confidentiality and integrity during computation and storage. Enclaves are absolutely private, isolated environments without built-in networking, offering high security;
On the other hand, each node features strong interactive communication capabilities powered by ZK. Using ZK protocols, nodes can prove the correctness of their computations to others without revealing raw data, significantly improving inter-node efficiency and trust. This enables flexible, plug-and-play service architectures across the entire distributed network. zkVM efficiently handles inter-node communication, verification of computational work, and incentivization—another key technical pillar underpinning Marlin’s superior node service capabilities.
Overall, understanding what Marlin does—and what it could do—is difficult to confine to any single use case, because at its core, it functions as a Zero-layer infrastructure protocol. Built on a high-performance TEE-enhanced node network and a ZK-verified communication layer, it can deliver tangible value across many trending narratives.
In my view, strong node service capabilities indeed open up diverse narrative possibilities in today’s highly composable and interoperable public chain ecosystem.
However, setting aside other potential application expansions, I believe that under the rising wave of the AI + DePIN narrative, Marlin has the potential to establish a primary business line:
1) Large AI models require substantial computing power, and Marlin already has GPU resources in place, giving it a first-mover advantage;
2) Marlin’s strengths in distributed node data privacy processing, secure computation, and efficient task allocation and scheduling make it well-suited for large and small AI model training and fine-tuning scenarios.
I believe this is precisely why Marlin, an established project, has managed to ride the current AI wave and regain momentum. AI will likely become its core narrative focus moving forward.
