The centralization trap in Layer 2 solutions hasn't loosened much, despite years of promises. Most L2 networks still depend on centralized sequencers to order and batch transactions. Upgrade mechanisms remain controlled by small teams rather than distributed governance. Trusted operators hold excessive power over network operations. This gap between roadmap visions and actual decentralization remains one of the biggest hurdles for the ecosystem—moving from theoretical scalability to truly decentralized infrastructure requires solving these coordination challenges.
