Parity Technologies(@paritytech):What can you build on @Polkadot? How about a light client small enough to run on an ESP32, powered by a 9V battery? 🔋 It follows the relay chain and verifies finality proofs locally, so it can read parachain state without trusting an RPC provider. Next: connecting it to the Devnet.

Polkadot light clients now fit on a microcontroller. Here is an ESP32 following the relay chain on a 9V battery 🔋 It verifies finality proofs locally, so it can securely read the state of any parachain without needing to trust an RPC provider. Next: hooking it up to the Devnet 👀
