Nodle Network is a DePIN project that rewards smartphone owners in NODL tokens for running the Nodl app. The app relays encrypted data from IoT devices like scooters or sensors to the blockchain, helping owners locate their devices.
Nodle started out on the Stellar blockchain back in 2017, then moved to its own Polkadot parachain before finally settling on on Ethereum's ZKsync layer 2.
For more details on the project, check out this interview with the founder, which I'll link to below.
