TL;DR · AI 摘要
Perplexity的SPACE系统通过加密身份验证确保请求正确路由到对应的沙箱执行实例，错误率低于0.0002%。
核心要点
- SPACE系统使用短期签名证明实现执行身份绑定，错误率低于0.0002%
- 沙箱迁移时通过执行ID+签名验证防止旧请求干扰新执行
- 请求可重新连接一次并重新通过身份验证

-  Our sandbox, SPACE, handles millions of executions a day with an error rate below 0.0002%. We’re sharing how it uses cryptographic identity to keep requests tied to the right execution as sandboxes pause, resume, and move. Read more:
-  When a sandbox resumes on another machine, it keeps its sandbox ID but starts a new execution. A stale route can send a valid request to the older execution and return old data. Checking the sandbox ID alone won’t catch the difference.
-  Each request carries short-lived, signed proof of which execution may handle it and what access is allowed. The receiving worker checks that identity against its own runtime record and rejects mismatches before forwarding.
