Lightweight blockchain

A lightweight blockchain is a modified blockchain with simplified algorithm without sacrificing data security.[1] This type of blockchain is suitable for applications that need for data reliability but limited computational resources[2] like Internet of Things (IoT)[3] and Autonomous Driving.[4] Especially in IoT, most of the connected devices are small, ubiquitous, and running on battery but aimed to work for a long period of time remotely and securely.[5] Lightweight blockchain enabled trust evaluation mechanism in wireless sensor network for secured data transaction between nodes.[6]

Theoretically, Blockchain is robust and unhackable.[7] 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.[8]

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.
