ETH Ethereum confirms the upgrade date for "Glamstam" and warns of the risks of "false" builders
According to CoinDesk and crypto.news, Ethereum's core developers have determined a specific date for the upgrade of "Glamstam". This upgrade is the next scheduled step in the Ethereum Continuing Protocol Improvement Roadmap, which follows the previous hard fork.
At the same time, developers issued a warning that there may be "fake" or malicious Builders on the testnet, which may interfere with the testnet environment that supports Glamsterdam-enabled. If such abuses are not resolved, they may hinder progress on the chain before the mainline network is deployed.
The key role of builders in block production
The core of this warning lies in the role of builders in the Ethereum block production process. Under the "Proposer-Builder Separation" model adopted by the network, a dedicated builder is responsible for building blocks, while a verifier selects which blocks to propose. This division of labor aims to reduce centralized risk and manage the economics of transaction sequencing, including maximum extractable value (MEV).
During testing, false or malicious builders may submit invalid or destructive blocks. This delays the verification process of upgrade code before entering the real network. Developers rely on testnet to detect such problems as early as possible and prevent them from affecting users 'real funds or transactions on the mainline network.
Risks and coordination challenges in the testing phase
以太坊的开发流程通常在主线网络部署前经过多个测试网阶段。每个阶段的目标是在模拟真实网络环境的条件下，暴露出漏洞、安全问题或意外行为。虽然此阶段的构建者滥用并不一定直接威胁主线网络用户，但如果需要修复，可能会使开发者协调工作变得复杂，并推迟更广泛的时间表。
Glamsterdam 升级遵循了以太坊近期硬分叉的命名惯例，即结合与开发者会议相关的城市名称。每次升级通常包含多项以太坊改进提案（EIPs），涵盖可扩展性、验证者经济学或执行层效率等领域。然而，现有报道中并未详述 Glamsterdam 的具体技术内容。
市场关注点与未来展望
随着区块构建市场变得更加专业化，且有时集中在少数专业运营商手中，以太坊核心开发者社区对构建者相关风险的警惕性日益提高。尽管 CoinDesk 和 crypto.news 均未详细说明在 Glamsterdam 测试网上观察到的虚假构建者活动的具体性质，但两家媒体均将此问题定性为开发者的警告，而非主线网络时间表本身的确切中断。
任何关于重大以太坊升级存在延迟风险的信号，往往会引起计划围绕分叉日期运作的验证者、节点运营商和基础设施提供商的关注。虽然停滞或延长的测试网阶段可能会推迟 Glamsterdam 的主线网络激活窗口，但目前尚未确认出现此类延迟。
目前，报道中的警告主要针对测试网条件，而非实时网络安全。关注以太坊路线图的市場参与者可能会期待核心开发者发布后续声明，以澄清虚假构建者问题是否已得到控制，或者在进一步测试之前是否需要协调修复。
以太坊开发者已为 Glamsterdam 升级制定了路线，同时指出了值得关注的测试网风险。来自核心开发团队的进一步更新将阐明构建者滥用问题是否会影响已确认的时间表。
常见问题解答
什么是 Glamsterdam 升级？
Glamsterdam 是以太坊网络的下一个主要预定升级，遵循该项目以开发者会议地点命名硬分叉的惯例。
开发者所说的“虚假”构建者是什么意思？
该术语指的是恶意或无效的区块构建者干扰 Glamsterdam 测试网，利用以太坊在测试期间的提议者-构建者分离流程。
这是否意味着以太坊主线网络面临风险？
不。报道中的担忧涉及用于验证升级代码的测试网阶段，而不是对以太坊实时主线网络上的资金或交易的活跃威胁。
这会导致 Glamsterdam 升级延迟吗？
开发者警告称，如果未解决构建者滥用问题，可能会阻碍进展，但目前没有报告证实宣布的日期会出现延迟。
