AVS stands for Active Validation Services, a term that essentially describes any network requiring its own validation system (e.g., oracles, DA, cross-chain bridges, etc.), which can be understood as projects using restaking services. By comparing Eigenlayer, Symbioticfi, and Karak Network, we can see more mature solutions and development potential, illustrating how AVS and restaking technologies eliminate the burden of building underlying trust networks, allowing projects to focus on developing new features and better decentralization.
