社区构想：为二手硬件做链上「护照」Community idea: an on-chain passport for used hardware
用户 0xKiter 提出给硬件做「护照」的构想：买二手硬件时，买家只能相信一张截图，无法判断 GPU 是否被挖过矿、修过或仍在保修期内。若每次维修、换件、保修事件与所有权变更都在 X Layer 上签名记录，买家扫一下标签就能看到这些历史。推文未说明实现方式与时间表。User 0xKiter proposed a hardware "passport" idea: when buying used hardware, buyers can only trust a screenshot and cannot tell whether a GPU was mined on, repaired, or still under warranty. If every repair, part replacement, warranty event and ownership change were signed and recorded on X Layer, a buyer could scan a tag and see that history. The tweet did not describe implementation or timing.
