Making Blockchain Fast Enough for IoT Networks

Blockchain is a promising solution for secure data sharing in the Internet of Things (IoT) networks, but existing systems often suffer from high latency that limits time-sensitive applications. Now, researchers from Japan have investigated how the structure of peer-to-peer blockchain networks affects IoT-blockchain performance. They developed Dual Perigee, a lightweight peer-selection algorithm that significantly reduces data propagation delays without increasing resource usage on IoT devices.
