Sign Protocol’s New Money System is the most underread section in their docs—I went over it four times before it clicked.
Last month I took a monetary policy class. We talked about CBDCs and why they’re politically tricky, not technically. Governments need visibility without mass surveillance, privacy without enabling money laundering, programmability without abuse. According to my professor, no one has solved all three.
Reading SIGN’s New Money System, I realized it actually tries. Supervisory visibility comes from attestation-based audit trails. Privacy is optional at the retail level. Programmability is controlled through smart contract limits and approvals. Public, private, and hybrid modes are supported, letting countries choose what fits reality.
CBDC adoption is slow—ten years in most jurisdictions, no retail CBDC rolled out at scale yet. Adoption curves matter more than token price. But with at least one country piloting SIGN’s infrastructure in 2026, the story changes.
I’m watching unlocks, pilot announcements, and central bank papers on attestation-based compliance frameworks closely.
Do you think a major economy will have a retail CBDC by 2028? Could SIGN get there first?
