#sign地缘政治基建 Many systems often face issues when there is no declaration left, but rather when they continue to use an old declaration that should no longer be recognized.

Recently, I have been paying more attention to this aspect with Sign. Just because an attestation has been written down does not mean the matter is concluded. We still need to observe what its current status is: has it been revoked, has it expired, has it been replaced by a new declaration, or has it even entered dispute. The official FAQ actually breaks down verification into very detailed parts, with a separate focus on status verification, which I believe is more crucial than many people think.

The problems with many systems precisely lie here: the conclusion remains, but no one continues to manage the status. On the surface, the record is still there, but in reality, it is no longer suitable to be directly used as a basis. Just like many people looking at the previous hash of $ETH , or looking at the last result of $BTC that has already fallen, they naturally think, "Since there is a trace, it counts." But leaving a trace and being continuously valid are two different things; the difference lies in whether it has been correctly updated, replaced, and verified afterwards.

So now I actually feel that Sign is not just about writing declarations on the chain or into the system, its more important step is to remind that the verification process should not stop at 'whether there is one', but should continue to pursue 'is it still valid now'. And this also explains why $SIGN should not be seen merely as an outer narrative; it actually corresponds to these real actions in the protocol: generating, querying, verifying, and handling status. @SignOfficial
