DIFFERENT TYPES OF LAYER 2S

Summary from the TLDR Crypto newsletter

This essay from Vitalik Buterin explains how the Ethereum layer 2 ecosystem is diversifying, with projects migrating from other chains to become a part of the Ethereum ecosystem. The ecosystem is witnessing an increase in projects building rollups, layer 1 projects moving towards validiums, and other new initiatives being launched. This growing heterogeneity reflects the different needs and strategic choices of various projects, particularly in striking a balance between costs, usability, and security.
