Blockchain Pioneer Warns of Central Bank Digital Currencies' Risks

W. Scott Stornetta, a prominent figure in the blockchain space, has expressed his concerns about the current state of central bank digital currencies (CBDCs). During his speech at Consensus Miami 2026, he stated that Bitcoin is still in its early stages and emphasized the need for caution when it comes to CBDCs.

According to Stornetta, the main issue with CBDCs is not the technology itself but rather the power dynamics it creates. He warned that if governments gain access to people's financial data without reciprocal transparency, it could lead to an 'asymmetric' system where individuals have limited control over their own information.

The IMF has published a handbook on CBDCs, highlighting both potential benefits and risks. While state-backed digital currencies may improve financial inclusion, payments competition, and cross-border settlement, they also pose concerns about data privacy, cyber resilience, bank funding, and run risk. The IMF emphasizes that poorly designed retail CBDCs could lead to significant issues.
