Now let's look at the LwTx architecture. The lightweight transaction architecture (LwTx) dualizes the blockchain model to maintain the verification of the blockchain while reducing the weight of the blockchain. The following figure shows the LwTx based blockchain structure. First, the initial block of the lightweight blockchain branches off and receives the last verified block of the heavyweight blockchain network. Second, transactions occurring in the lightweight blockchain network are sequentially collected and stored in a lightweight block and repeat this process until certain conditions are met.
Third, when the number of blocks of the lightweight blockchain is more than a certain number or the execution time of the lightweight transaction reaches the synchronization time limit, the blocks of the lightweight node are broadcast to the heavyweight blockchain to join the blockchain network. Therefore, these blocks became part of the heavyweight blockchain block. Fourth, in the heavyweight blockchain, if the blocks of the lightweight blockchain are properly verified and reflected, all blocks in the lightweight blockchain are deleted after a certain period of time, and the subsequent lightweight blockchain creation process is continuously performed.
