What Are zk-Rollups? The Layer-2 Scalability Technique Explained
As blockchain adoption accelerates, scalability has become one of the most critical challenges facing the industry. Congested networks lead to slow confirmations, rising transaction fees, and a poor user experience. To address these limitations, developers have turned to two broad approaches: upgrading blockchains directly at the base layer, and building complementary systems on top of existing networks.
zk-Rollups belong to the second category. They are a Layer-2 scalability technique that aims to preserve blockchain security while dramatically improving speed, cost efficiency, and privacy.
