ECB outlines three models for putting central bank money onchain - The Block

The European Central Bank has outlined three possible models for bringing central bank money onto distributed ledgers, according to The Block. The proposals respond to a practical problem: as tokenised assets and blockchain-based settlement grow, transactions still need a final, risk-free settlement asset. Central bank money is that anchor, and the ECB is examining how it could exist onchain without compromising the safety of the existing monetary system.

The three models represent different degrees of central bank involvement and technical complexity, though the specifics of each remain subject to further design and testing. The core question is how to preserve the qualities that make central bank money trusted — stability, finality, and universal access — while operating in programmable environments. Each model carries trade-offs between innovation, control, and operational risk.

For markets, the significance is directional rather than immediate. If central bank money becomes usable onchain, it could support more efficient settlement of tokenised securities and other digital assets, reducing reliance on commercial stablecoins for that function. What to watch: which model the ECB favours, how it engages commercial banks, and whether the work moves from experimentation toward concrete infrastructure.
