DSLIOT – Bringing Order to Things: Decentralized and Scalable Ledgering for the Internet-of-Things

BOOT is a prototype of a decentralized ledgering solution for the IoT implementing a Decentralized Coordination Model with Byzantine Fault-Tolerant Transactions authenticated by Resilient Group-Oriented Thershold Signatures as service modules on top of a Permissioned Blockchain Infrastructure. The solution is supported by the Hyperledger Fabric Platform, enabled to run as a service in Cloud-nodes. Rather than replacing the cloud, our solution presents a scalable and fault-tolerant middleware for recording transactions between peers, under verifiable and decentralized trustability assumptions and authentication guarantees for logged operations performed by IoT devices, cloud services and users. The solution uses smart hubs as blockchain-access gateways, aggregating, pre-processing and forwarding small amounts of data and transactions in proximity conditions, with operations verified and processed as authenticated transactions in the blockchain.

The prototype was developed in th conetxt of a MSc Thesis: https://run.unl.pt/handle/10362/55172
