Ethereum Strawmap: 7 quantum-safe hard forks by 2029
Ethereum’s roadmap, “Strawmap,” aims to make the blockchain quantum-resistant by 2029. Led by the Ethereum Foundation, the plan spans seven hard forks starting in 2026 and focuses on migrating Ethereum’s consensus and cryptography to post-quantum schemes.
Key changes include a new consensus model called Single Slot Finality. The goal is to cut transaction finality time from up to ~15 minutes today to under 16 seconds, reducing the risk of reversals and chain reorganizations.
On the cryptography side, Ethereum plans to replace existing elliptic-curve algorithms with hash-based signature systems and STARK-powered solutions designed to resist quantum decryption advances.
Scheduled upgrades: the Glamsterdam hard fork is targeted for the first half of 2026, followed by Hegota later in 2026. After that, additional hard forks are expected at roughly six-month intervals.
The article notes urgency because scientists warn commercial quantum computers could be available within 4–5 years. Ethereum says each phase must meet its timeline to avoid critical security vulnerabilities as quantum capabilities progress. The transition is also relevant to Layer-2 scaling, after recent testnet-related disruptions.

总体偏中性。利好点在于“Ethereum Strawmap”提供了清晰的抗量子路线图，且包含更快的交易终局（从约15分钟降至16秒以内），从中长期叙事上增强安全性与可预期性。历史上类似的重大协议升级（例如以太坊扩容与共识相关的迭代）往往会先带来市场想象空间，但价格通常更取决于落地进度与整体风险偏好。
短期内，市场可能会出现“升级预期”带来的情绪波动，但由于发布时间跨度到2029年、关键硬分叉要从2026年逐步启动，且升级涉及共识层与加密层大规模改造，落地的不确定性（实现难度、测试网反馈、可能的技术延误）会限制单边上涨。
对交易者的影响：1）关注后续关于 Glamsterdam、Hegota 以及后续硬分叉的开发进展与测试网稳定性；2）若出现与 Layer-2 测试/集成相关的风险事件，可能带来阶段性承压；3）若升级里程碑被反复确认、技术指标兑现，可能提升中期风险溢价下降，从而对ETH估值形成支撑。
