DIA Expands Fully On-Chain Oracle Solution to Optimism’s OP Testnet

Following the recent deployment of DIA Lumina on the Arbitrum testnet, DIA continues its mission to redefine oracle transparency and verifiability. The next step in this journey is the expansion of DIA’s fully on-chain oracle stack to Optimism’s OP testnet. This marks yet another milestone in DIA’s roadmap toward delivering trustless and immutable data infrastructure for Web3 applications.

For too long, blockchain oracles have relied on off-chain computation, introducing trust dependencies and limiting data transparency. DIA Lumina challenges this paradigm by executing all data operations—storage, verification, aggregation, and computation—entirely on-chain. This is made possible through Lasernet, DIA’s dedicated Layer-2 rollup, which ensures that every data point is processed via immutable smart contracts that anyone can deploy and verify in a fully decentralized manner.

With the OP testnet deployment, developers can now experiment with DIA Lumina’s on-chain price feeds using both pull-based and push-based oracle mechanisms. This flexibility allows seamless integration of transparent, decentralized data feeds tailored to the needs of Web3 applications.

DIA Lumina is not just an evolution of oracle technology—it is a fundamental redefinition of how oracles should function in a decentralized world. By eliminating off-chain dependencies, DIA provides a fully verifiable data journey, where every piece of information can be tracked, audited, and proven directly on-chain.

With more testnet expansions on the horizon and a mainnet launch approaching, DIA remains committed to shaping the next generation of oracle solutions—where trustless data becomes the new standard.

Stay tuned for more updates as DIA Lumina continues its journey toward redefining on-chain data integrity.
