Abstract

以太坊于5月7日顺利完成Pectra升级,覆盖Staking、L2扩容与账户抽象三大方向。本文简明梳理三项关键改动的技术细节与意义,包括验证者质押上限上调至2048 ETH、Blob 扩容降低L2成本,以及EIP-7702推进账户抽象,带来更流畅的钱包体验。

5 月 7 日以太坊顺利完成 Pectra 升级。作为今年极为重要的一次主网升级,Pectra 围绕 StakingL2 扩容账户抽象三大方向,为以太坊未来的发展奠定了新的基础,接下来为大家梳理本次升级的核心看点。

一、Staking 机制优化:从 32 ETH 提升至 2048 ETH

本次升级中,EIP-7251  将单个验证节点的质押上限由 32 ETH 提升至 2048 ETH,这一改动带来两个重要意义:

1、提升 Staking 入金与提现速度

以太坊过去为了保持去中心化,将单节点质押上限设为 32 ETH。但这也带来了在网络高峰期入金与提现排队时间过长的问题,尤其是每个 Epoch 仅允许 8 个节点退出或提现。

本次升级将单节点上限提高至 2048 ETH,未来节点合并后,资金流动效率将大幅提升,尤其在牛市等高峰期,能有效缓解排队压力。

虽然当前处于低谷时段,入金与提现普遍可在 10 分钟内完成,但此改动将为未来的网络拥堵提前打好基础,优化整体用户体验。

2、为 L1 扩容预留空间

以太坊目前拥有超过百万个验证节点,在确保每个节点公平参与共识的机制下,L1 的峰值性能长期受限,当前维持在约 60 TPS。

将单节点质押上限提升至 2048 ETH 后,未来有望逐步引入更灵活的分层共识机制,例如大节点全员表决 + 小节点随机表决的组合模式。

这一方案在轻微降低安全门槛的同时,有望显著释放链上性能,为 L1 的可扩展性打下基础。

如图,采用 Orbit 模式可能是 ETH L1 扩容的思路。

正因如此,Pectra 升级中推动 2048 ETH 上限成为扩容路径中的关键一步。

3、LST 协议受益

Pectra 升级引入的 EIP-6110 与 EIP-7002 ,为包括 Lido、EtherFi 在内的 LST 协议带来了底层机制上的突破性支持:

  • EIP-6110 允许直接在共识层完成存款操作

  • EIP-7002 赋予智能合约对提现流程的控制权限

这两项改动使原本依赖中心化组件和手动流程的部分环节,得以实现更高程度的去中心化与自动化。

尽管围绕 LST 的讨论仍存在争议,Pectra 升级无疑为这一生态释放了更大的发展空间。

二、L2 优化:Blob 扩容带来更低成本

本次升级中,EIP-7742 EIP-7691 的实施,将 Blob 容量直接扩容一倍,并支持动态调整。

Blob 作为 L2 数据存储和备份的核心区域,直接关系到 L2 的成本结构。此次升级后,L2 费用将进一步降低,从“非常便宜”迈向“极致便宜”,对 L2 生态无疑是利好。

当然,这也意味着 ETH 的燃烧速度可能会进一步放缓。不过,从生态整体健康度来看,L2 活跃度与低成本无疑具有更长远的战略价值。

三、账户抽象迈出关键一步

以太坊Pectra升级三大看点

EIP-7702  的引入为以太坊账户抽象打开了新篇章,显著提升了钱包的灵活性与用户体验:

  • 支持批量交易,操作更加高效

  • 允许使用任意代币(如 USDT)支付 Gas,降低门槛

  • 引入社交找回等机制,增强账户安全性与易用性

过去,钱包功能较为固化,且需预先准备 ETH 才能发起交易。未来,基于 EIP-7702 的账户抽象钱包将更加自由与智能,新用户甚至可以直接通过手机号注册、使用钱包,无需担心地址管理与 Gas 预置等繁琐步骤,彻底打通以太坊体验的“最后一公里”。

结语

Pectra 升级不仅仅是一次常规的功能迭代,它在 Staking 机制优化、L2扩容与账户抽象等关键领域,为以太坊的未来描绘了更清晰的路径。Ebunker 已完成所有 Pectra 升级适配工作,接下来我们将继续专注于为以太坊生态提供高效、稳定的验证服务。未来的变化仍将持续发生,感谢你和我们一起关注、参与、建设以太坊生态。

Valuation Inversion Emerges, Bitcoin Treasury Companies Face Trust Crisis

"Valuation Inversion Emerges, Sparking Trust Crisis for Bitcoin Treasury Firms" The investment thesis for corporate Bitcoin treasury stocks has fundamentally shifted. Investors are no longer rewarding companies simply for accumulating more Bitcoin. Instead, the focus is now on net Bitcoin per share, with intense scrutiny on whether new financings truly benefit existing shareholders or merely dilute their stake. Key indicators highlight the new reality. Metaplanet's market capitalization has fallen below the total value of its Bitcoin holdings, indicating a valuation discount. While MicroStrategy maintains a premium, its core metric—Bitcoin per diluted share for common shareholders—has been declining due to dilution from financing activities, primarily through its STRAT permanent preferred shares. This marks a transition from a pure "asset accumulation" phase to an "equity attribution" phase. Investors now deduct costs like preferred dividends and debt to calculate the actual Bitcoin claim for common equity. The widespread adoption of spot Bitcoin ETFs has removed the scarcity value these stocks once held, forcing them to justify their structure with superior leverage, dividends, or capital efficiency. European entrants like France's Capital B and Sweden's BTC AB are testing this new environment with ambitious funding plans backed by relatively small Bitcoin holdings. They are asking investors to bear complex capital structures, betting future Bitcoin purchases will cover all dilution and dividend costs. The sector's core risk is a broken financing loop. Once a company's stock trades below its Bitcoin net asset value, it loses the ability to issue equity for accretive purchases. It is then left with unpalatable choices: dilutive financing at a discount, venturing into new businesses like Bitcoin lending, or selling assets. The winners in this next phase will be those that demonstrably increase Bitcoin per share for common shareholders with every financing move.
