In the competitive landscape of blockchain infrastructure, Layer 0 protocols have long played the role of "invisible pipelines." While end users rarely notice them directly, these protocols fundamentally shape the data throughput, latency, and finality of decentralized applications. Marlin stands out as a leading project in this arena.
Around 2019, a team of engineers with backgrounds at Microsoft, Adobe, and other major firms officially introduced the Marlin protocol, aiming to build a programmable transport layer for decentralized networks. The POND token launched in December 2020. Since then, the project has gradually rolled out its relay network, gateway, and MarlinVM edge computing components, forming a three-tier architecture that covers data propagation, block broadcasting, and off-chain computation.
Marlin’s vision stems from a reimagining of the blockchain network layer. In traditional internet architecture, content delivery networks have already reduced latency to the millisecond level, yet communication between blockchain nodes still relies heavily on unoptimized gossip protocols. The core challenge Marlin seeks to address is this: as consensus and execution layers in blockchains continue to improve, the network layer—responsible for data transfer between nodes—remains a long-overlooked performance bottleneck.
As of July 3, 2026 (UTC+8), Gate market data shows Marlin’s native token POND is priced at $0.0012254, with a 24-hour drop of 30.70%, a 7-day gain of 1.82%, a 30-day decline of 24.94%, and a year-to-date decrease of 84.81%. The market cap is approximately $10.0512 million, with a 24-hour trading volume of $237 million. The total supply is fixed at 10 billion tokens.
Off-Chain Computation Execution Logic: Why Computation Must Move Off the Main Chain
At its core, a blockchain is a deterministic state machine—every transaction is executed repeatedly on all nodes to ensure consistent state transitions. While this "redundant execution" model provides security and decentralization, it also comes at a significant cost to computational efficiency. As smart contract logic grows more complex and compute-intensive tasks like AI inference or zero-knowledge proof generation move on-chain, performing all computation on the main chain becomes economically unfeasible and technically impractical.
Marlin’s solution is to move computation off-chain, where a distributed network of nodes executes the tasks, then submits the results along with verifiable proofs back to the blockchain. This model, known in academia and industry as "verifiable computing," ensures both scalability and trust.
The execution flow works as follows: a smart contract registers a computation task request via an on-chain relay contract. The relay contract queues the request. Off-chain gateway nodes monitor for task registration events and, following the protocol’s work distribution logic, assign tasks to worker nodes. After completing the computation, worker nodes submit both the results and correctness proofs on-chain. The verification contract checks the proof; only results that pass verification are accepted by consumer contracts, and only then are worker nodes rewarded.
Essentially, this design transforms blockchains from "general-purpose computation platforms" into "trusted anchors for verifiable computation." The main chain no longer executes computations but instead verifies them. Computation happens off-chain, while the main chain is responsible only for final confirmation and settlement.
Two Technical Paths for Verifiable Computing: TEE and ZK
The core challenge of verifiable computing is this: how can an untrusted server prove it has executed a computation correctly? Marlin offers two parallel technical approaches—Trusted Execution Environments (TEE) and Zero-Knowledge Proofs (ZK).
TEE Path: Hardware-Level Trust Anchor. Marlin’s Oyster subnet is a TEE-based verifiable computing protocol that deploys computational workloads across a decentralized network of TEE nodes. TEEs provide a protected execution area within the processor, isolating code and data from other processes to prevent unauthorized access or tampering. Computation runs off-chain within this trusted environment, with logic and data shielded from both the host and blockchain visibility. Hardware manufacturers supply remote attestation mechanisms, allowing on-chain verification contracts to confirm that computations were executed on genuine TEE hardware.
The key advantages here are generality and performance. Oyster nodes function much like standard servers, capable of running any program—including AI model inference, complex financial modeling, and other general-purpose tasks. Oyster supports two deployment models: Oyster CVM and Oyster Serverless.
ZK Path: Cryptographic Integrity of Computation. Marlin’s Kalypso subnet operates as a ZK proof marketplace, using an order book model to create a separate market for each circuit. Proof demanders (users, applications, protocols) and proof generators (hardware operators) negotiate on price and generation time. Kalypso connects to various hardware solutions, including Accseal ASIC cards and mining servers.
In the ZK path, worker nodes generate zero-knowledge proofs of the computation process, and on-chain verification contracts validate the ZK proofs. This approach’s main advantage is that it removes the need to trust any hardware vendor—security is guaranteed entirely by cryptography. The combination of Oyster and Kalypso enables Marlin to serve as a flexible, cost-effective co-processor solution for verifiable computation.
These two paths are not mutually exclusive. Developers can choose based on their specific needs: for scenarios demanding high performance and where hardware trust is acceptable, the TEE path is suitable; for situations requiring greater decentralization and trustlessness, and where computations can be represented as circuit proofs, the ZK path is preferable.
Network Acceleration and Node Distribution: The Economic Incentives of Marlin Relay
Marlin’s core infrastructure is its relay network. Blockchains are essentially broadcast networks—every block produced by a validator must be propagated to all other nodes. On proof-of-work (PoW) chains, block propagation speed directly impacts orphan rates, which in turn affect network security and decentralization. On proof-of-stake (PoS) chains, block times of just 1–2 seconds further compress the propagation window.
Current P2P networks operate under an unincentivized commons model, where participant interests are not aligned. Full nodes, which are essential for decentralized and censorship-resistant propagation, are not rewarded for their contributions. This lack of incentives also introduces uncertainty in block arrival times across the network.
Marlin Relay addresses this by introducing economic incentives. Nodes in the network compete to propagate blocks, pooling bandwidth and reducing tail latency. This approach boosts both the security and throughput of blockchain network layers. Node operators must stake at least 1 MPond (equivalent to 1 million POND) to participate in the relay network and earn POND rewards based on performance. POND and MPond are interchangeable via a bridging contract at a fixed 1:1,000,000 ratio, but converting MPond back to POND involves time delays and liquidity constraints to safeguard network economic security.
In terms of distribution, Marlin has established a globally distributed, decentralized node network. Each node not only relays and caches data but also comes equipped with a TEE, creating secure enclave environments within storage systems. This architecture enables Marlin to provide compute and storage resources for use cases like oracles, ZK prover systems, and AI applications.
Marlin’s Relationship with Layer 1 and Layer 2: The Logic of Layer 0 Positioning
To understand Marlin’s relationship with Layer 1 and Layer 2, it’s helpful to return to the fundamentals of the layered model. Layer 1 is the base blockchain layer, handling transactions and smart contracts, secured by PoW or PoS, and serving as the primary settlement layer. Layer 2 consists of scaling solutions built atop Layer 1, increasing throughput by moving transactions off-chain. Layer 0, by contrast, focuses on even more foundational aspects—hardware optimization, data routing, and cross-chain consensus coordination.
Layer 1 and Layer 2 scaling in blockchains corresponds to improvements in layers 5–7 of the internet stack, while Layer 0 aligns with layers 1–4 of the internet. As a Layer 0 protocol, Marlin is blockchain-agnostic, providing a network-layer gateway for multiple Layer 1 and Layer 2 platforms.
This relationship can be likened to a highway system: Layer 1 is the highway itself (lanes, toll booths, traffic rules), Layer 2 is the express or high-capacity lanes (improving traffic flow), and Layer 0 is the foundation and communications infrastructure beneath the highway—determining how information moves between segments with minimal latency and maximum efficiency.
Marlin’s relay network is designed to compress block propagation latency to the sub-100-millisecond range, offering an order-of-magnitude improvement over default gossip broadcasting mechanisms. This performance boost is valuable for any blockchain network that relies on block propagation—whether Layer 1 or Layer 2. Marlin also connects validators directly to the network via gateways, enabling more efficient communication and enhanced node security.
However, Layer 0 protocols face a common challenge: low user visibility. Most public blockchain node operators can optimize their own transmission paths without relying on third-party relays. The benefits Marlin delivers may be substitutable under low-load conditions. Its long-term value depends on a yet-to-be-proven hypothesis: as large-scale Web3 application interactions become the norm, demand for network determinism at the application layer—and willingness to pay for it—will rise significantly.
Conclusion
The essence of decentralized computing networks is transforming blockchains from "computation executors" to "computation verifiers." Through its Layer 0 architecture, dual-path verifiable computing (TEE and ZK), and incentive-driven relay network, Marlin provides a comprehensive infrastructure layer for this shift.
From accelerating data propagation to verifying off-chain computation, from hardware-level TEE security to cryptographic ZK integrity, Marlin’s technical stack covers the entire spectrum of decentralized computing, from the network layer up to the computation layer. Its complementary—not competitive—relationship with Layer 1 and Layer 2 gives it a unique position in the blockchain infrastructure ecosystem.
It’s worth noting that value capture remains a core challenge for Layer 0 protocols. When market sentiment turns cautious, these "backend infrastructure" projects are often the first to see liquidity dry up. As of July 3, 2026, POND is trading at $0.0012254 with a market cap of about $10.0512 million, down 84.81% year-to-date, reflecting a cautious market stance toward this narrative. Whether Marlin’s technical vision can translate into sustainable commercial value still awaits the test of large-scale Web3 application adoption.
