DIA Distributed Feeder Network: A New Paradigm for Trustless Oracle Data Sourcing

The reliability of on-chain data is the foundation of DeFi. Oracles bridge the gap between off-chain and on-chain worlds, ensuring that decentralized applications (dApps) operate with accurate, real-time data. However, the majority of existing oracles rely on opaque, centralized third-party aggregators, creating a fundamental trust issue.

DIA Lumina is changing this dynamic with the DIA Distributed Feeder Network: an open, permissionless network of independent nodes that fetch, aggregate, and publish computed data points directly onto DIA’s Lasernet rollup. This marks a significant evolution in the oracle space, ensuring transparent, verifiable, and tamper-resistant data feeds.

The Distributed Feeder Network comprises independent Feeder nodes run by infrastructure providers, data specialists, and validators. Each Feeder acts as a coprocessor – an off-chain computation layer that enhances blockchain capabilities by handling complex or resource-intensive operations off-chain while ensuring verifiability and trustlessness.

These Feeder nodes execute four essential functions:

• Data Fetching: Feeders retrieve on-chain and off-chain data directly from first-party data sources  (CEXs, DEXs & other direct sources), eliminating reliance on third-party aggregators.
• Computation: The collected data is aggregated off-chain, where price points are structured from atomic trade blocks rather than relying on opaque, external calculations.
• On-Chain Submission: Verifiable price points are submitted to DIA Lasernet, making them available for dApps and smart contracts to consume.

From there, these on-chain data points are publicly accessible, allowing users to permissionlessly deploy Aggregator smart contracts to create fully custom price feeds using data from these Feeders and apply custom computational logics.

This model establishes a fully trustless, open-source oracle framework, enabling anyone to verify how prices are formed, updated, and distributed—bringing radical transparency to blockchain oracles.

DIA’s Distributed Feeder Network is a major leap forward in oracle technology, addressing key pain points in the industry:

• Eliminates Middlemen – Traditional oracles often depend on centralized third-party aggregators that introduce opacity. With DIA’s model, data is sourced firsthand from markets.
• Fully Trustless – Every step of the process – data fetching, aggregation, and publishing, is verifiable on-chain.
• Continuous Availability – Distributed Feeder nodes ensure redundancy and uptime.
• Future-Proof Incentives – Feeder nodes will be rewarded based on performance, uptime, and data accuracy, with slashing mechanisms to penalize incorrect reporting.

An initial cohort of eight battle-tested node and blockchain infrastructure providers have been onboarded and successfully deployed Feeders on mainnet. These nodes have demonstrated 100% uptime and reliability, earning verified status within the network.

The first verified Feeder providers include: Restake, Liquify, Chainbase, Stakecraft, Globalstake, Blockscape, Aleno, and Stakin.

With the foundation set, the network is now fully open and permissionless. Node operators, infrastructure providers, and validators can now deploy and run their own Feeders, actively contributing to the decentralization of oracle infrastructure.

Organizations can deploy their own Feeders to fetch any data they require and and process it in a permissionless manner within Lasernet—ensuring a truly open and decentralized data ecosystem.
