The problem
What today's M2M auth can't deliver in cbdc settlement.
Wholesale CBDC and inter-bank settlement architectures need authentication between validator nodes operated by different central banks and clearing systems. No central party can plausibly own the authentication authority across jurisdictions, and post-quantum migration is on every central bank cryptographic agenda.
How EdSSA addresses it
What EdSSA does differently here.
EdSSA Nano provides validator-to-validator authentication that does not require a global central authority. Each pair of validators bootstraps once via post-quantum primitives; inter-validator messages authenticate stateless thereafter. The architecture is jurisdiction-neutral and post-quantum from launch.
Use cases
Concrete operational scenarios.
- Cross-border wholesale CBDC settlement with inter-central-bank validator authentication
- Domestic real-time gross settlement (RTGS) inter-validator authentication
- Tokenised securities settlement with post-quantum operator authentication
- Inter-clearinghouse authentication for cross-jurisdiction settlement
