The long-term vision for Ethereum is increasingly shifting beyond incremental upgrades toward a more fundamental transformation of its core architecture. As the network continues to scale and support a growing ecosystem of decentralized applications, developers and researchers are exploring whether achieving ETH’s ultimate goals of global scalability, security, and decentralization requires rebuilding elements of its base layer rather than simply refining existing systems. Rebuilding Core Infrastructure For Long-Term Growth Ethereum’s evolution has moved beyond incremental upgrades; it is entering a phase of structural reconstruction. The head of research at EigenCloud, Soubhik Deb, mentioned on X that the initiative often referred to as Lean Consensus, formerly known as née Beamchain, signals the beginning of ETH’s endgame
