The situation in the Middle East has been a bit volatile these past two days, so I revisited @SignOfficial . I used to think that this type of project was too focused on infrastructure and not very appealing, but my thoughts have changed a bit now.
To put it simply, something like $SIGN is actually addressing the issue of "trust becoming expensive." In the past, many things across regions were assumed to be established, but now it's different, especially when different systems are involved, and many validations have started to become troublesome.
At this time, a neutral verification layer on a blockchain starts to make some sense.
My current feeling about $SIGN is that, in the short term, it may not be stimulating, but if the environment continues to become more complex, the logic behind such projects will actually become more coherent.
