The authors propose a privacy protocol for CBDC interbank settlement that uses a relaxed sender anonymity model on a permissioned EVM, combining Groth16 ZK proofs and Poseidon commitments to keep transaction content confidential while keeping the sender auditable.研究者提出一种面向CBDC银行间结算的隐私协议，采用放松的发送方匿名模型，在许可EVM上结合Groth16零知识证明和Poseidon承诺实现交易内容保密，同时保持发送方可审计性。研究者らは、CBDC銀行間決済向けに、許可型EVM上でGroth16ゼロ知識証明とPoseidonコミットメントを組み合わせ、送信者の監査可能性を保ちつつ取引内容を秘匿する、緩和された送信者匿名性モデルを提案した。
NotesNotes要点
- Proposes a relaxed sender anonymity model: sender identity public for compliance, receiver and amount hidden.
- Implemented on permissioned Hyperledger Besu with QBFT consensus and Groth16 (BN254) proofs.
- Uses Poseidon hash in an incremental Merkle tree and ECIES multi-recipient encryption for note storage.
- On-chain NoteRegistry contract acts as append-only ledger, removing need for trusted off-chain custody.
- Five-node experiment: end-to-end settlement 8-16 s, on-chain verification ~220k gas.
- Prototype's NoteRegistry uses owner-indexed events, leaking privacy; production can use uniform broadcasting.
