Ethereum co-founder Vitalik Buterin has called on cryptocurrency projects to prioritize decentralization to prevent power concentration and associated risks. In his article "Balance of Power," Buterin highlights the tendency of projects to focus on business models while neglecting decentralized structures. He argues that while some systems, like language and open protocols, naturally resist centralization, others require deliberate design to achieve decentralization. Buterin stresses the importance of balancing centralization's efficiency with decentralization's benefits, urging projects to integrate decentralization as a core design principle.
