On March 29, when @SignOfficial brought what they are building to Harvard Kennedy School, discussing with research groups from Cato Institute, Nanyang Technological University, and MIT Digital Currency Initiative, I observed a very clear fact.
Traditional financial systems are no longer efficient enough for the next phase of society.
This context is driving strong interest in sovereign CBDC operating systems that Sign Protocol is directly building with many countries.
But the issue is not just about speed or cost. It lies in the fact that current systems are not designed to operate in a digital world, where data, identity, and cash flow need to interact in real-time.
Instead of just improving payment infrastructure, they are building a sovereign CBDC operating system as a new financial infrastructure layer, where money is not only digitized but can also be programmed, controlled, and directly integrated with data layers such as identity and policy.
At the technical layer, the system combines programmable ledger and verifiable credentials, allowing each transaction to carry conditions and verification states, enabling the issuance, distribution, and control of cash flow to occur within a unified logic.
Importantly, Sign does not seek to replace existing organizations. They build tools for banks and governments to expand existing systems rather than dismantle and rebuild from scratch.
As these implementations begin to appear in many countries, one thing becomes clear. The competition is no longer between blockchains but between systems that can operate the digital economy at sovereign scale.
