In recent days, Iran has become increasingly hardline, with the Speaker directly stating: there will be no concessions; any invasion will come at a cost. This statement makes it clear—there is no turning back; both sides are digging in, positions are tightening, and trust has basically hit zero. It is no longer just a matter of military strength, but also of statements, determination, and information warfare. Today's commitments can be overturned tomorrow, current declarations can quickly become strategies, and every word you hear has an underlying purpose. Who said what is not important; **what really matters is whether it can be verified**. This is also the reason I am increasingly concerned about $SIGN . I used to think that 'national-level trust infrastructure' was somewhat distant, but now it seems more real than ever. It does not take sides, does not resolve wars, but does one fundamental thing: **it pins behavior, information, and identity to verifiable records**, preventing the truth from being distorted by narratives. On the battlefield, firepower is key; in the information realm, credibility matters. As trust becomes increasingly scarce, verifiability itself is the hardest infrastructure. #SIGN #SignGeopoliticalInfrastructure $SIGN#sign地缘政治基建 $SIGN @SignOfficial
