DIA Launches Testnet for Lumina Modular Oracle Infrastructure
DIA has launched the testnet for Lumina, a modular oracle infrastructure that enhances transparency, scalability, and integration flexibility. Lumina addresses issues with existing oracles by enabling data aggregation, verification, and delivery across blockchains.
Unlike other oracle solutions such as Chainlink and API3, Lumina supports multiple messaging protocols, is compatible with non-EVM chains, and offers comprehensive data traceability.
Previously, the origins and flow of oracle data were often unclear. Lumina provides full visibility into this process, as stated by Zygis Marazas, DIA’s head of product.
“Users can clearly see the entire data journey, from the source to the final price calculation,” Marazas noted. This transparency aims to build trust in data reliability and accuracy.
The testnet went live recently with limited participation. The mainnet is scheduled for release in Q1 2025, operating as a fully permissionless network. New chains and assets requiring oracle services can integrate without direct involvement from DIA’s team, eliminating manual onboarding processes.
“You can set up your own oracles if you wish, completely permissionlessly,” Marazas explained. This feature is expected to attract developers working on emerging rollups and specialized blockchain ecosystems, where speed and autonomy are critical.
This capability should facilitate the entry of diverse assets into DeFi, according to Aiham Jaabari, co-founder of Silo Finance, which utilizes DIA oracles. “Very few oracle providers offer data feeds beyond blue chips — that’s why we’re excited about Lumina,” Jaabari said. “You can create an oracle permissionlessly on a layer-2 for any token asset.”
Lumina’s architecture integrates various data sources by aggregating information from multiple origins, including blockchain networks and external APIs, ensuring broad coverage and accuracy.
“You can get data from any source — offchain or onchain — from the hundreds of feeds available in the market,” Marazas added.
For enhanced scalability, Lumina employs an OP Stack-based rollup called Lasernet and uses Celestia for data availability, making it an optimized rollup equivalent to a validium.
Marazas expressed confidence in Celestia’s roadmap toward one-gigabyte blocks, considering the scaling benefits to outweigh minor risks associated with added dependencies, aligning with the broader modular trend.
While Lumina is optimized for Ethereum rollups, it also supports non-EVM ecosystems like Cosmos and Move-based chains, utilizing Hyperlane as a cross-chain messaging protocol but adaptable to other standards as needed.
Lumina's flexibility includes support for both push and pull models of data delivery, allowing users to select the approach that best suits their needs. “Some customers prefer a pull-based approach for on-demand prices, while others find push-based updates more efficient,” he noted.
Jaabari emphasized that control over the oracle is as crucial as the data feed itself since no single methodology fits all assets. He also praised the layer-2 strategy as “the cheapest way to process data and make it available.”
Decentralization is integral to Lumina’s roadmap. Although the testnet will initially rely on whitelisted data feeders, DIA plans to gradually open participation in 2025, introducing staking and slashing mechanisms to ensure data accuracy.
“The vision of our protocol is that eventually it will operate independently of the core team,” stated Marazas.
