Most CBDC announcements are MoUs. Headlines strong, commitment weak. That's why when I saw the update from Kyrgyzstan, my first reaction was… another MoU will happen.
But this was different.
On October 24, 2025, Sign's CEO Xin Yan and the Deputy Governor of the National Bank of Kyrgyz Republic signed a technical services agreement. This means real build. There are deliverables, there are deadlines. Target: To make Digital SOM legal tender by January 1, 2027.
Why did this deal happen?
Governments do not want vendors, they want ownership. The core question is: who will have control? Sign's answer is straightforward. Nodes are yours. Rules are yours. Infrastructure is yours. The Sign Protocol is just an attestation layer. The core stack runs on Hyperledger Fabric X, which is on the central bank's hardware.
Compliance is also practical. Welfare payments often go through intermediaries. Every step adds delay and cost. With Digital SOM, payments can be programmed directly, only for specific use cases like education or healthcare. AML and CFT checks run in the background.
Privacy is handled by ZK-proofs. Transactions are verified without exposing details. Sensitive data remains off-chain. On-chain, there are only attestations.
But the real test is yet to come.
Phase three covers offline and low-connectivity payments. Kyrgyzstan's terrain and rural gaps make this critical. If offline payments are not strong, inclusion will remain limited to urban areas.
There is also a public chain bridge. Digital SOM connects with KGST on the BNB Chain. This seems like a more future use case.
And the biggest question is about scale. A sovereign contract is a strong signal. But by 2028, multiple countries need to be onboarded for 300 million users. Kyrgyzstan is proof. Scale is still to come.
Sign has built a sovereign stack that can be adopted without sacrificing control.
Now the question is how fast this system scales… and whether it can reach mountain villages.
