CBDC & DLT Architecture

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

CBDC architecture comparison > ISO20022/DLT mapping > CBDC interoperability modelling > DLT platform comparison > DLT decision framework — composite CBDC/DLT architecture mandate.
