币界网报道：Ethereum's decentralized vision faces scaling hurdles as high transaction costs and network congestion persist, despite its transition to proof-of-stake. Developers acknowledge the blockchain struggles to balance decentralization with efficiency, as layer-2 solutions like Arbitrum and Optimism handle over 60% of transactions. Vitalik Buterin recently proposed "enshrined rollups" to simplify scaling while maintaining security, but critics argue this may compromise Ethereum's core principles. The network's average transaction fee remains around $1.50, significantly higher than competitors. With adoption growing but fundamental issues unresolved, Ethereum's community debates whether pragmatic scaling compromises its original decentralized ethos.
