In the past few days, I finished reviewing the latest technical documents and GitHub commits of @SignOfficial , and compared them with the actual performance from the testnet. I found that the story they tell about 'low-cost verification' does not match the real consumption at all. My own tests on the Base chain showed that completing a full identity Attestation costs between $0.7 and $1.2 in Gas, and during peak network congestion, it even surged to $1.8. The white paper claims 'inclusive low cost, far below traditional institutions,' but in practice, it simply does not hold up. #BTC
Xin Yan mentioned in the recent AMA that the Sign verification engine has been deeply optimized for compliance scenarios in the Middle East, but I checked the latest code commits, and the ZK proof module is still only available on the testnet, with no open entry on the mainnet. What confuses me even more is that there is no fixed settlement logic between the Hyperledger Fabric chain they built for the government and the public chain $SIGN token; there is neither mandatory staking nor a burn channel, and the demand for the token relies entirely on expectations.
I compared the free system of UAE Pass with the current usage costs of Sign, and ordinary users have no motivation to switch. Developers in the community are also complaining about the high cost of schema deployment, slow proof generation, and high cross-chain synchronization delays; these issues have been raised for months without a clear repair timeline. In my view, Sign's geopolitical narrative is very rich, but the actual product experience, cost structure, and token value capture are all not working out; no matter how smoothly the story is told, it cannot fill the gap in implementation. $BTC
