On the other hand, Lightweight Blockchain does not perform mining to verify generated blocks.
Each lightweight participating node collects transactions that occur between nodes inside the lightweight blockchain network.
Even if it is not synchronized with the heavyweight blockchain in real time, transactions within the lightweight blockchain are performed normally.
Lightweight nodes regularly broadcast the collected transactions to the heavyweight blockchain, and light weight blocks are verified by participating nodes.
Normally verified lightweight blockchain transactions can be deleted from the lightweight blockchain after a certain period.
