Sign Protocol is not a testnet project anymore. Sierra Leone is running its national digital ID on it. The UAE Web3 Entrepreneur Program uses it. TokenTable has distributed over 4 billion dollars across more than 40 million wallets. Real governments. Real citizens. Real money already moving through this infrastructure.
So I went back and read the whitepaper carefully. Most of it is solid. The attestation layer makes sense. The three layer SIGN Stack is well designed. The zero knowledge proof integration for identity verification is exactly what sovereign infrastructure needs.
But one part stopped me completely.
The entire Sovereign Chain runs through a single government controlled sequencer. Every citizen transaction flows through it before validators see anything. If that sequencer goes offline the whitepaper says one thing only. Exit to L1 if the L2 experiences issues.
That is the whole plan. One sentence.
Who decides to trigger that exit. Not specified anywhere.
How long until recovery begins. Not specified anywhere.
Is there a backup sequencer waiting. Not specified anywhere.
sIgn is targeting 50 million users in the first deployment year. For infrastructure operating at that scale, three unanswered questions in the technical document is not a small gap. That is the entire failure plan absent.
