- A lightweight blockchain is a modified blockchain which has a simplified algorithm without sacrificing data security. This type of blockchain is suitable for applications that need data reliability, but limited computational resources like Internet of Things (IoT) and Autonomous Driving. Especially in IoT, most of the connected devices are small, ubiquitous, and run on battery but aim to work for a long period of time remotely and securely. Lightweight blockchain enabled trust evaluation mechanism in wireless sensor network for secured data transaction between nodes. Theoretically, Blockchain is robust and unhackable. The downside of this technology is the intensive energy consumption needed for hashing, block validation and proof-of-work due to the nature of Distributed Ledger. An experiment shows that using an IoT gateway as a trusted node and sensor data as distinctive tags for IoT sensor node authentications via the modified authenticated encryption scheme in a lightweight blockchain network can accommodate up to 1.34 million authentication processes every second, which is more than sufficient to be applied in a resource-constrained IoT network and even in health sector.
