Improving the scalability of blockchain through DAG
Qin Wang · 2019
Current blockchain systems face the problems of poor scalability, low performance, and high cost. To address the previous bottlenecks, we plan to employ the DAG-based structure as the primary method and propose a concrete model, called 3D-DAG, to improve the scalability. The model consists of two layers: mainchain and sidechain, which separately severs for maintaining the pivot sequence and improving the parallelism. Our expecting results should significantly improve the performance and scalability without compromising the security.
