“…There are two categories of CTs; (1) Ring CTs which obfuscate the senders and receivers with shadow participants refs. [18][19][20][21][22] and (2) Aggregable CTs which allow aggregating multiple transactions into one transaction by removing spent coin records refs. [1,2,[10][11][12][13][14].…”

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.
