摘要

“保密货币价值”包含有关真实货币价值的信息,但不披露它。具有机密货币价值的后量子私有区块链-具有大量验证时间的大型区块链-具有最小的可扩展性,因为它们需要比具有“明文货币价值”的区块链保存和验证更多的信息。高可扩展性是去中心化区块链支付系统的基本安全要求,因为有能力验证区块链副本的诚实对等体越多,安全性就越高。我们提出了一种用于机密货币区块链的量子安全交易协议LACT+(基于晶格的可聚合机密交易),它比以前的后量子机密区块链更具可扩展性,即许多具有对数大小复杂性的输入/输出交易。

LACT+: Practical Post-Quantum Scalable Confidential Transactions
A “confidential monetary value” carries information about the real monetary value but does not disclose it. Post-quantum private blockchains with confidential monetary values—large-sized blockchains with large verification times—have the least scalability because they need to save and verify more information than those with “plain-text monetary values”. High scalability is an essential security requirement for decentralized blockchain payment systems because the more honest peers who can afford to verify the blockchain copies are, the higher the security. We propose a quantum-safe transaction protocol for confidential monetary blockchains, LACT+ (Lattice-based Aggregable Confidential Transactions), which is more scalable than previous post-quantum confidential blockchains, i.e., many input/output transactions with logarithmic sized complexity.
