Why can't I open the app?

Recently, many people have been asking how the Sign project is and whether it's worth participating. I took some time to research it and found that it is indeed a bit different—not just a project relying on storytelling and fundraising, but one with real income, a clear business model, and a team that continues to deliver.
Let's start with the background. Sign has already secured $32 million in funding, backed by well-known institutions like Sequoia Capital and YZi Labs. This is not a small amount, indicating that investors are seriously optimistic about its long-term value.
What's even more impressive is that Sign achieved $15 million in revenue in 2024 and is still profitable. This is quite rare in the Web3 space. Most projects are still in the money-burning stage, but Sign has already become self-sustaining. The revenue primarily comes from two areas: one is Sign Protocol, which serves as government-level digital infrastructure, and has collaborated with countries like the UAE and Thailand for digital identity and data verification; the other is TokenTable, a token distribution platform that has serviced over $4 billion in asset distribution and has more than 40 million users.
