作者：叶慧雯，华尔街见闻 以太坊今日正在执行名为"Fusaka"的关键网络升级，这是其持续扩展路线图中的又一重要里程碑。此次 升级旨在通过大幅提升数据容量和优化协议效率，进一步降低Layer-2网络的交易成本，巩固以太坊作 为全球高效结算层的核心地位。 根据计划，Fusaka升级在区块高度13,164,544处被激活。这是继Dencun和Pectra升级之后，以太坊在扩展 道路上迈出的新一步。高盛加密业务负责人Kenny Lee指出，Fusaka代表了以太坊可扩展性路线图的下 一阶段，其目标是推动网络演变为一个兼具全球影响力与成本效益的结算层。 此外，Fusaka升级还包括引入"仅Blob参数"（BPO）分叉机制，使未来的网络容量提升更加灵活；同时 通过存储过期和区块控制等功能优化Layer-1主网性能，并改善钱包功能与用户体验。这些变化共同构 成了以太坊在可扩展性、可持续性和操作性方面的一次结构性飞跃。 从Dencun到Fusaka：专注扩展与基础设施优化 Fusaka升级实际上是共识层"Fulu"升级与执行层"Osaka"升级的同步激活。根据以太坊基金会确认的最终 方案，升级所包含的以太坊改进提案（EIP ...

Core Insights - Ethereum is executing a critical network upgrade named "Fusaka," aimed at significantly enhancing data capacity and optimizing protocol efficiency to lower Layer-2 transaction costs and solidify its position as a global settlement layer [1][2] - The Fusaka upgrade is scheduled to be activated on December 3, 2025, at block height 13,164,544, following the Dencun and Pectra upgrades [1] - The upgrade introduces "PeerDAS" technology, which theoretically increases Layer-2 network data capacity by 8 times, thereby improving transaction throughput and reducing user transaction fees [3][7] Upgrade Details - The Fusaka upgrade synchronously activates the consensus layer "Fulu" and execution layer "Osaka," focusing on three main areas: enhancing Layer-2 data capacity, optimizing fee mechanisms, and improving user experience [4][6] - Key features of the upgrade include the introduction of the "only Blob parameters" (BPO) fork mechanism for flexible future capacity increases, and optimizations for Layer-1 performance through features like storage expiration and block control [3][6] Layer-2 Focus - Ethereum's design philosophy prioritizes decentralization and security at Layer-1, leading to high transaction fees and slow confirmation times as demand for decentralized applications grows [5] - The "Rollup-centric" roadmap shifts most transaction processing to Layer-2 networks, allowing for off-chain execution and compressed data publication back to Layer-1 for final settlement [5] PeerDAS Technology - PeerDAS addresses data availability issues by allowing nodes to download only a fraction (approximately 1/8) of the total data, significantly reducing resource requirements and enabling an estimated 8-fold increase in data capacity [7] BPO Fork Mechanism - The BPO fork mechanism allows for lightweight updates to Blob-related parameters, enabling more frequent and safer deployments to gradually increase data capacity without major upgrades [10] Fee Market Stability - The introduction of a "base price" mechanism for Blob fees aims to ensure that fees reflect economic value and maintain market sensitivity to network congestion, providing a more stable pricing environment for Layer-2 [11]
