Dia has been working on the decentralized layer 2 oracle for some time now. And recently the tweet came out that they are launching the testnet for the Lumina. And they would be making use of the optimism stack for the oracle. And this launch is going to be making the launch possible with the permissionless oracle system on the layer 2, which many projects could benefit from as well.
So now you would see the roll up as a service with this oracle network along with other services on the chain too. Which would make it easier for the blockchain to also have the non EVM and EVM interoperability along with the oracle data.
As from the tweet you can gauge it's built on the optimism stack so low fees on the token and also the speed and performance along with the roll up service is kind of expected and is about to happen as well. I think those who are expecting the roll up based oracles would find this growth from DIA useful for their decentralized projects too.
I feel there is going to be growth in the interoperable chains, oracles and the rollup based services. But the way ethereum layer is ignored by market that needs a change, this layer 2 is more valuable than solana. Let's see how market pushes this.
