Scalable Digital Currency for Central Banks
summary
Argues for a government-issued electronic token that users hold in non-custodial wallets and that keeps payers anonymous while allowing recipients to verify receipt. Implements blind signatures for initial issuance, a public permissioned DLT only for externalizing commitments, and Merkle tree commitments so relays cannot equivocate. Core design is to separate issuance from consensus so no issuer tracks every token and transactions avoid perpetual on‑chain costs; work exists as a research prototype with central bank engagement, not a deployed system.
