The European Central Bank has outlined three possible architectures for bringing central bank money into tokenized financial markets.
In an October 1 presentation, ECB Executive Board member Isabel Schnabel described direct issuance of tokenized reserves, a bridge between existing real-time gross settlement systems and distributed ledgers, and a private-intermediary model involving settlement tokens backed by reserves. ecb.europa.eu
Direct issuance would place central bank reserves natively on a programmable ledger. The bridge model would leave reserves in the existing settlement system while connecting transactions to distributed ledgers through synchronization and cryptographic links.
Under the private-intermediary approach, an institution would hold reserves at the central bank and issue corresponding settlement tokens. Those tokens would be fully backed but would remain private liabilities rather than direct claims on the central bank.
The ECB has already launched Pontes, which offers settlement through either TARGET2 or Eurosystem distributed-ledger infrastructure. Planned enhancements include continuous availability and decentralized programmability. Project Appia is examining unified, interconnected and multiple shared-ledger architectures. The Block
TOKEN RECON ASSESSMENT
The central design decision is who issues the final settlement asset. Direct tokenized reserves preserve a claim on the central bank, while private settlement tokens introduce intermediary, legal and operational risk even when fully reserved.
The presentation is a framework, not a final architecture decision. The selection made under Appia will determine whether Europe’s tokenized markets converge around public settlement money or depend on a collection of interoperable private claims.
