Programmable settlement
Public money becomes an accountable execution layer: value, rules, identity constraints, and finality written into the same institutional surface.

Scene 02 / The Prism
Three lenses for a public ledger
Network
Resilient distribution
A CBDC rail is never a single machine. It is a lattice of policy nodes, payment providers, banks, citizens, and contingency paths.
Vault
Trust under glass
The design question is not whether trust disappears, but where it is held, how it is audited, and who can see through the glass.
Scene 03 / The Architecture
Money becomes infrastructure
In the architecture of a central bank digital currency, the unit of account gains an address, a route, a permission layer, and a memory of settlement.
Policy Strata
Wholesale rails, retail wallets, offline instruments, liquidity bridges, and privacy thresholds stack like frozen plates over a deeper legal substrate.
Scene 04 / The Debate
The Promise
Instant public settlement, cheaper cross-border corridors, programmable safeguards, and monetary instruments that remain sovereign in a private platform age.
Counterweight
The Peril
Surveillance creep, brittle governance, exclusion at the edge, and the quiet migration of monetary discretion into software defaults.
