Lasernet Mainnet is Live: DIA Lumina’s Full Rollout is Here

With the mainnet deployment of Lasernet, DIA Lumina’s full oracle architecture is now live. This marks a paradigm shift in the Web3 data infrastructure landscape: introducing the first fully decentralized, trustless, and transparent oracle environment.

For the first time, developers, DeFi protocols, and Web3 builders can access oracle data that is completely verifiable, and executed trustlessly on-chain. No more black-box oracles. No more unverifiable price feeds. Just pure, transparent, and trustless data, directly from the origin.

Lasernet is a custom-built Layer 2 rollup designed to process oracle data trustlessly, at scale. It powers the DIA Lumina oracle stack, leveraging optimistic rollup technology and a modular Data Availability (DA) layer, both built by Arbitrum, to bring unparalleled security and efficiency to on-chain data delivery.

Unlike traditional oracles that process data off-chain in opaque systems, Lasernet brings every part of the oracle lifecycle on-chain—ensuring full verifiability and decentralization.

How Oracles on Lasernet Work

• Modular data availability – Lumina ensures secure and cost-effective on-chain storage of oracle data, verifiable at any time.
• Permissionless access – anyone can deploy an oracle smart contract to build data feeds with custom settings. Contracts live immutable forever on Lasernet.  
• Trustless Data Processing – Every oracle transaction is public, auditable, and resistant to manipulation.

With Lasernet now live on mainnet, DIA Lumina becomes the first oracle ecosystem to fully decentralize every component of its architecture.

Lasernet’s mainnet deployment marks the completion of the entire DIA Lumina oracle stack, bringing the following components live:

Feeders (First-Party Data Sourcing Nodes)

Instead of relying on opaque third-party aggregators, Lumina brings first-party data directly from the sources via a distributed network of Feeders. These are nodes that fetch, aggregate, and publish computed data points onto the DIA Lasernet in a verifiable way.

Lasernet (L2 Rollup for Oracles)

A high-throughput, low-cost Ethereum Layer 2 built to handle oracle data requests on-chain with full verifiability and trustless execution. It inherits Ethereum’s security while enjoying fast 250ms block times and cheap and efficient transactions.

Aggregator (Oracle Computing Smart Contracts)

These smart contracts on Lasernet that collect and process data available on the network, enabling the on-chain oracle computation with full transparency and permissionless deployment.

Spectra (Cross-chain Interoperability Framework)

DIA leverages Hyperlane’s open-source interoperability framework to connect DIA’s Lasernet to hundreds of layer-1 and layer-2 networks in a trust minimized and open way, via a network of validators.

$DIA as the Native Gas Token

Lasernet transactions now run on $DIA, embedding real economic utility into the token and aligning incentives across the network.

With these components now operational, DIA Lumina is not just another oracle—it’s the foundation for a fully trustless, modular oracle ecosystem.

Lasernet’s deployment isn’t just another mainnet launch—it’s a fundamental shift in how oracles work. Here’s why this matters for DeFi, dApps, and the entire Web3 ecosystem:

100% Transparency Across the Data Journey

Legacy oracle designs deliver price feeds that users must trust without verification. With DIA Lumina, every single data point is fully auditable onchain.

Trustless Execution at Scale

Existing oracles rely on offchain trust assumptions—whether it’s multi-sig-controlled nodes or centralized data providers.

Lasernet eliminates these risks by using an L2 rollup to handle data verification transparently and trustlessly.

Modular, Cost-Efficient, and Fully Verifiable

By optimizing the cost of data processing through rollups, Lasernet delivers oracle data at a fraction of the cost—without compromising security or decentralization.

A New Standard for DeFi Security

With oracles securing billions in DeFi  TVL, accurate and trustless data feeds are critical. DIA Lumina sets a new industry benchmark for data transparency, verifiability, and trustless execution.

Now that Lasernet is live, it’s time for builders, developers, and projects to start integrating the future of oracles.

👨‍💻 For dApp developers:

• Start integrating DIA Lumina oracles into your dApp. Deploy your own oracle or use an existing one.

📈 For chain foundations:

• Need decentralized, verifiable data infrastructure to kickstart a robust DeFi ecosystem for your chain? Let’s talk integration.

⛓ For stakers:

• Staking will be introduced soon—stay tuned for updates on how you can participate in securing the network.

Web3 has evolved. Blockchains are becoming more modular, scalable, and transparent—so should oracles.

Lumina’s mainnet deployment marks a major milestone in oracle design–it’s the first to bring full transparency, decentralization, and trustless execution to the oracle space.

Let’s build the future of oracles—together.
