Scalability Solutions for Blockchain Systems:

"A Survey on the Scalability of Blockchain Systems" provides a brief survey of recent studies on scalable blockchain systems, discussing scalability from the perspectives of throughput, storage, and networking. It presents existing enabling technologies for scalable blockchain systems (Xie, Yu, Huang, Xie, & Liu, 2019).

"Solutions to Scalability of Blockchain: A Survey" covers existing scaling solutions for blockchain and classifies them by level, making comparisons between different methods and listing potential directions for solving the scalability problem of blockchain (Zhou, Huang, Zheng, & Bian, 2020).
