Notes

• Anonymous payment protocols have linear growth of nullifiers, limiting scalability
• Evolutionary nullifiers allow permanent trimming of nullifiers without destroying unspent funds
• Oblivious synchronization model uses remote services to generate concise proofs, services are unaware of transaction details
• Services maintain temporary states, users can freely switch services
• This technology does not increase user computation, bandwidth, or latency costs
• Enhances privacy protection, preventing service linking users with transactions

• 匿名支付协议存在无效器线性增长问题，限制扩展性
• 演化无效器技术允许永久修剪无效器，不破坏未花费资金
• 遗忘同步模型使用远程服务生成简洁证明，服务对交易细节不可知
• 服务仅维护临时状态，用户可自由切换服务
• 该技术不增加用户计算、带宽或延迟开销
• 增强隐私保护，防止服务链接用户与交易
