SDK Proxy: Hyperledger Fabric Identities for Lightweight IoT Devices
Channel: Hyperledger Foundation
Date: 2019-01-02

Gero Dittmann & Jens Jelitto, IBM Research

IoT devices that sign their own transactions establish a trusted channel from the device to the blockchain with no need to trust any intermediary on the way. Running an entire SDK executing the Hyperledger protocols, however, may not be possible on devices with little processing and memory resources.

The SDK Proxy is a cloud service that enables such lightweight IoT devices to sign their own transactions while off-loading the communication with Hyperledger Fabric to the proxy. This significantly reduces the footprint of the client while maintaining the trusted channel from the device to the peers.

The demo shows an IoT device signing and submitting sensor readings via the SDK Proxy to Hyperledger, peers verifying the readings' signature, and the device receiving acknowledgments for the transactions.
