Nodle

Nodle is a smartphone-based DePIN network branded the Digital Trust Network, for enterprises needing media authenticity, asset location, and proof of location, addressing the high cost of Bluetooth IoT access and the difficulty of verifying location data. Its mechanism uses millions of smartphones and routers to form a decentralized wireless network via Bluetooth Low Energy (BLE), where installing the app turns a device into a node that powers the ConnectX enterprise toolkit for asset location; the Click App lets users cryptographically sign photos or videos to a blockchain to fight misinformation, and ContentSign authenticates media on-chain. The NODL token incentivizes participation and recently added staking.

Nodle's DePIN position is as a phone-powered trust layer, differing from hardware-dependent networks on cost and reach. The network was originally built significantly on Polkadot, then expanded to ZKsync and Ethereum L1 and, by late 2025, retired its Polkadot-to-ZKsync bridge in favor of a ZKsync- and Ethereum-centric multichain layout; real deployments include asset-tracking work with enterprises in South Africa and France, showing crowdsourced BLE tracking at production scale.
