Stornetta: Bitcoin just starting, CBDCs worry him
W. Scott Stornetta, an early blockchain figure cited in Bitcoin’s tech roots, said Bitcoin is only in the “first inning of the game” for blockchain finance, not the “endgame.” He warned central bank digital currencies could give governments big power over financial data. Stornetta called stablecoins a “terrific example” of blockchain use going past what Bitcoin started. Stocktwits
Central bank digital currencies are getting more attention as they move out of the research stage. CBDCs — digital forms of government-backed money issued by central banks — are under review in 146 countries and currency unions. These account for over 98% of global GDP, according to the Atlantic Council. Out of those, 77 are in more advanced phases and 41 have pilot projects going.
They dropped into a soft crypto market. Bitcoin hovered around $78,229, off roughly 1.1% on the day. Ether traded near $2,181, down about 1.8% from its last close.
Stornetta spoke during Consensus Miami 2026, CoinDesk’s digital-assets event held May 5-7 at the Miami Beach Convention Center. Crypto firms, payment outfits, policymakers and investors came as usual, looking to figure out what’s left after a fresh shakeout in digital assets.
Stornetta is more than just a market watcher. Back in 1991, he and Stuart Haber published “How to Time-Stamp a Digital Document,” introducing ways to verify the creation or alteration of digital files while keeping them confidential and not relying on a timestamp service to keep huge records.

Stornetta says Bitcoin started things off, but Ethereum, stablecoins, Bitcoin layer-2 networks and Ordinals have moved it along. Smart contracts are software rules that run transactions if certain conditions happen. Layer-2 networks get built on top of Bitcoin and bring new features or scale. Ordinals let people index data on the Bitcoin blockchain.
CBDCs got a clearer warning. Stornetta said his problem isn’t digital money itself. It’s the “asymmetric” system when the government gets access to people’s financial data, but people don’t get the same about the government. When asked if that sort of CBDC would be okay, he said: “No, probably not.” Stocktwits
Central banks are making a different case. The IMF’s CBDC handbook says state-backed digital currencies, if built right, might help with financial inclusion, payments competition, and cross-border settlement. It also points out worries over data privacy, cyber resilience, bank funding, and run risk.
But there’s a clear risk if a retail CBDC is poorly designed: it could track personal spending, hold lots of sensitive data, and trigger deposit outflows from banks during stress. The IMF warns CBDCs are not a “silver bullet” for inclusion, and says retail deposits could move fast to safe havens when markets face pressure. IMF
Stornetta’s remarks land both ways for private crypto firms. On one hand, they back the view of Bitcoin as just the first working model of a bigger financial idea. But the comments also raise the bar for Ethereum, stablecoin players and Bitcoin projects to show lasting use beyond pure trading cycles.
For policymakers, the debate is more focused and tougher: can digital money make payments better but not add more surveillance? Stornetta didn’t say CBDCs need to go away. He said the system needs to keep power in check.
