以太坊已启动公开测试网 Plataberget,开发者开始为 Glamsterdam 升级做前期验证。这一网络面向外部开放,目的是在进入 Sepolia、Hoodi 等长期运行测试网前,先检查一批底层改动是否稳定。

测试网向外部开放

以太坊基金会将 Plataberget 定位为 Glamsterdam 的早期测试场。Glamsterdam 这一名称由 Gloas 和 Amsterdam 两次计划中的升级组合而来。

该测试网采用无许可方式运行,开发者、验证者和其他用户都可以接入测试。按计划,网络将部署约 5 万名验证者,分布在约 50 个节点上,并测试不同客户端组合的兼容情况。

ETH 转账 gas 规则调整

此次升级中,与普通用户关系最直接的变化之一,是 ETH 基础转账的 gas 计算方式。向已存在账户转账时,gas 仍维持 21,000;但如果转账目标是新账户,系统将因新增链上状态数据而额外收取 state gas。

这意味着,默认把所有 ETH 转账视为同一成本的钱包、gas 估算器和相关工具,都需要在主网上线前完成更新,否则可能出现费用估算偏差。

合约上限与执行机制同步调整

Glamsterdam 还包含多项协议层改动。ePBS 将把 proposer-builder separation 直接写入以太坊核心规则,改变区块构建方式,并减少对外部区块构建系统的依赖。BALs 则会记录区块执行时访问了哪些状态数据。

  • 智能合约大小上限由 24 KiB 提高至 64 KiB
  • initcode 大小上限由 48 KiB 提高至 128 KiB
  • 相关 gas 调整将支持约 2 亿的更高 gas floor

这些改动的目标,是为以太坊基础层留出更大处理空间。按当前安排,待 Plataberget 上的测试趋于稳定后,开发团队将把 Glamsterdam 推进到 Sepolia 和 Hoodi 等长期运行测试网,主网升级目标仍指向 2026 年下半年。
