BIS unveils anonymous CBDC prototype with cash-like privacy

  • —Design relies on BBS+ signatures, zero-knowledge proofs and segregated bank ledgers
  • —ZKP proof generation takes about 0.4 seconds for a single coin and 1.76 seconds for 20 coins
  • —Includes limited anonymous wallets and partial freezing of individual UTXOs
  • —Losing a private key in a maximum-anonymity wallet means funds cannot be recovered
Why it matters: The findings set a technical benchmark for central banks weighing privacy against regulatory oversight in CBDC design.
