Ethereum is at a critical juncture in history. In 2025, Ethereum underwent a strategic shift from "Rollup-centric" to "Layer1 scaling back to the core." Although the Dencun upgrade in 2024 reduced Layer2 data costs by over 90%, it led to a shrinkage in Layer1 on-chain activity, with ETH burn rates dropping to historic lows, raising deep concerns within the community about economic sustainability. In the face of these challenges, the Ethereum Foundation officially released the "Scale L1" strategy, aimed at revitalizing the Layer1 ecosystem and building the "Teragas ecosystem" with a total throughput of 10 million TPS to support global on-chain activities. Behind this technological transformation lies the Ethereum team's commitment to the core values of decentralization. Unlike other public chains that trade performance for higher node hardware thresholds, Ethereum has consistently adhered to the principle of "decentralization," opting for a more challenging but ultimately more meaningful zero-knowledge technology route. When the Succinct team demonstrated that 93% of Ethereum blocks could generate ZK proofs within 12 seconds, when the zkEVM team vowed to achieve Layer1 ZK at "any cost," when Beam Chain planned to arm the consensus layer with ZK technology, when ZK-Rollup was on the verge of a long-awaited revival, and when the vision of replacing EVM with RISC-V was put on the agenda, can this technological bet spanning the execution layer and consensus layer achieve performance breakthroughs while ensuring decentralization? Deeper changes are quietly occurring at the governance and capital levels. Public companies like BitMine and SharpLink are incorporating ETH into their balance sheets on a large scale, and staking ETFs are on the horizon, with traditional financial forces integrating into the Ethereum ecosystem like never before. Meanwhile, the once-booming re-staking sector has hit a growth stagnation, and the foundation has shifted from the "infinite garden" philosophy to commercial operations.
