Marlin (POND) is a next-generation blockchain network protocol engineered to accelerate decentralized web operations through enhanced speed, security, and reliability. In the rapidly evolving digital ecosystem, efficient communication between nodes is essential—especially in blockchain networks that rely on peer-to-peer (P2P) data transmission over the public internet. Traditional network infrastructure often struggles with latency, congestion, and scalability, creating bottlenecks that hinder blockchain performance. Marlin addresses these challenges head-on by optimizing the underlying network layer, ensuring faster block propagation, reduced latency, and improved overall throughput—without compromising decentralization.
The Origins and Evolution of Marlin
Founded in 2017 by Siddhartha Dutta, Prateesh Goyal, and Roshan Poddar, Marlin was born out of a clear need: to solve the inefficiencies in blockchain’s P2P communication architecture. The founding team brought together deep expertise in distributed systems, network engineering, and blockchain development—drawing talent from institutions like the Ethereum Foundation and tech giants including Facebook and Cisco.
Marlin’s early breakthrough came in late 2019 with the launch of OpenWeaver, a low-latency overlay network framework. This was followed by Marlin Cache in 2020, which improved data accessibility for decentralized applications (DApps). A major milestone occurred when the Marlin Relay was deployed across over 800 nodes, significantly boosting block dissemination speeds.
In 2021, Marlin expanded its utility by releasing mev-bor for Polygon, enabling efficient MEV (Miner Extractable Value) bundle propagation. The introduction of Oyster in 2022 added secure computational capabilities via Trusted Execution Environments (TEEs). Most recently, Kalypso, unveiled in late 2023, introduced a decentralized marketplace for Zero-Knowledge (ZK) proof generation—further solidifying Marlin’s role as a performance and privacy enabler in the Web3 stack.
Backed by prominent investors such as Arrington Capital and NGC Ventures, and advised by leading academics and industry experts, Marlin continues to push the boundaries of what’s possible in decentralized networking.

How Marlin Works: Network Architecture and Performance Optimization
At its core, Marlin operates as a layer-0 protocol, meaning it functions beneath existing blockchains to enhance their communication infrastructure. It breaks down network operations into four key components: creation, management, packet propagation, and monitoring.
The system begins by forming a relay network from available Marlin nodes. These nodes act as high-speed conduits for data, particularly blocks and transactions, ensuring rapid delivery across geographically dispersed validators. A critical feature is performance-based accountability: nodes must stake POND tokens to participate, aligning incentives with network reliability.
To maintain integrity, Marlin employs a decentralized monitoring system where underperforming or malicious relay networks are penalized. This enforcement is made possible through a Schelling-point-based auditing mechanism—auditors are incentivized to report truthfully, preserving transparency and trust.
Data packets are propagated using the Marlin SDK, which allows seamless integration with various blockchain clients. This modular design supports customization while maintaining low-latency transmission—crucial for time-sensitive operations like block publishing.
Security Enhancements: TEEs and Zero-Knowledge Proofs
Security and privacy are foundational to Marlin’s architecture. Two key technologies underpin its advanced security model:
Trusted Execution Environments (TEEs)
TEEs create isolated, hardware-secured environments—often referred to as "secure enclaves"—where code and data can be processed without exposure to the host system. Marlin leverages TEEs through its Oyster execution layer, allowing sensitive computations to run securely. This ensures confidentiality and correctness, even on untrusted infrastructure. Additionally, Oyster generates on-chain verifiable attestations, proving that computations were executed as intended.
Zero-Knowledge (ZK) Proofs
With the launch of Kalypso, Marlin introduced a decentralized marketplace for ZK proof generation. ZK proofs allow one party to verify the validity of a computation without revealing the input data—ideal for privacy-preserving applications. Kalypso connects users who need proofs with providers who offer computational power, reducing costs and latency associated with ZK proof creation. This innovation makes privacy-enhancing technologies more accessible and scalable across blockchains.

Key Innovations: MEV Insights, Gateway Integration, and Caching
Marlin has developed several tools that extend its impact across the blockchain ecosystem:
- MEV Dashboard: Tracking MEV activity on Polygon since January 2021, this tool provides real-time insights into arbitrage opportunities, helping traders and developers optimize strategies.
- Gateways: These lightweight connectors enable direct integration between blockchain validators and the Marlin network, enhancing communication speed without compromising node security. Supported chains include Ethereum, Polygon, Polkadot, and more.
- Marlin Cache: A decentralized caching solution that stores frequently accessed data, reducing query times and improving DApp responsiveness—especially beneficial for high-traffic applications.
These innovations collectively strengthen Marlin’s position as a performance layer that enhances scalability, security, and user experience across multiple platforms.
Core Use Cases of the Marlin Protocol
Marlin’s optimized network layer enables a wide range of applications:
- Decentralized Finance (DeFi): Faster transaction finality and reduced latency improve trade execution, lending speed, and oracle updates.
- Content Delivery Networks (CDNs): By decentralizing content distribution, Marlin enables faster global access to media and web assets.
- Decentralized Exchanges (DEXs): Enhanced throughput supports higher trade volumes and reduces slippage during peak times.
- Blockchain Scalability: As a layer-0 solution, Marlin helps scale multiple blockchains simultaneously by improving inter-node communication.
What Is POND? The Native Token of Marlin
POND is the native ERC-20 token of the Marlin protocol, serving three primary functions: staking, governance, and payment of network fees.
With a maximum supply capped at 10 billion tokens, approximately 8.08 billion POND were in circulation as of early 2025. The tokenomics are structured to promote long-term participation and decentralization.
Users can stake POND to run Metanodes or join the relay network, earning rewards for contributing bandwidth and computational resources. Additionally, every 1 million POND can be converted into 1 MPOND, a non-transferable governance token used to vote on protocol upgrades, funding allocations, and cross-chain deployments.
This dual-token model separates operational utility (POND) from governance rights (MPOND), promoting fair decision-making while maintaining economic stability.
