坎昆升级（Dencun Upgrade）通过 EIP-4844 等提案大幅降低 L2 数据存储成本，推动行业进入 "性能过剩 但生态不均" 的分化阶段。这种分化并非简单的 "强者恒强"，而是呈现交易集中度、技术路线、生态活 力、流动性分布的多维失衡，具体表现如下： 一、交易格局：头部链垄断超 60% 交易量，中小项目陷入萎缩 坎昆升级后，不同技术路线的 L2 项目性能与成本分化加剧。Optimistic Rollups（如 Arbitrum、 Optimism）成为最大受益者，Arbitrum 手续费从 0.62 美元降至 0.01 美元，降幅高达 97.01%，Optimism 手续费降幅也超 90%，凭借低成本吸引大量小额交易用户。而 ZK Rollups 系（如 Linea、Scroll、Polygon zkEVM）由于技术架构差异，手续费降幅不足 50%，仍维持在 0.5 美元以上，成本劣势导致用户流失明 显。这种分化背后是技术 trade-off 的现实体现：ZK Rollups 虽具备即时最终性优势，但数据压缩与证明 生成的成本未能通过坎昆升级有效降低，短期内难以缩小与 Optimistic Ro ...

Title is mid and misses the meat of this article, but it's worth pulling forward:Pi² has effectively productized all of the work that is left to validators of chains optimistically settling to Ethereum.That means the ~7d challenge window which is typically full of capital and compute-intensive games between parties can be settled ~instantly and without debates (because math).This imbues a shit ton of verifiable, fast trust between parties, which means bridges, chains, users, et al can move on to once it ob ...
