We treat the blockchain as a Source of Truth for the DAWN network. It’s the place that anyone — hardware, operators, etc. can look at to know what is the intended state of the network. Nodes will then get verified to ensure they are implementing the correct network state. But to do that verification often requires a good chunk of data that somehow needs to make its way into an on-chain program. It’s easy to see how that scales as you’re trying to validate things that can change multiple times a day (think a wireless link having variable performance). And this is one of the major unsolved challenges in DePINs — telemetry and how to make trustless operations on that data. Telemetry is just not well suited for blockchains, so something else is needed to help DePINs scale. Data Anchor solves this exact problem for us. Data is captured in ledger space, so it’s still on-chain. That data’s compressed state is rolled into account space for whatever relevant window we need, and then utilized when operations on that data actually need to be performed to validate node state. I say this very generically and abstractly because I think that’s the power of this new tool from the gigabrains at @Terminaxyz. I can give specific examples of how exactly we use this for our Proofs, but that’s a separate post. In the meantime, just wanted to celebrate this new announcement from them because it tackles a piece of DePIN no one has managed to solve yet — scaling telemetry to actually play a role in network state.
