The Future Ring Confidential Transaction Protocols for Privacy-Preserving Blockchain
摘要
In this chapter, we are going to give some potential future enhancement on the privacy-preserving blockchain protocol, the Ring Confidential Transaction (RingCT) protocol, which is currently used in the largest cryptocurrency Monero. Our future enhancements include the shortening of the size significantly, from linear to logarithm to the number of possible senders of the transaction. Another cutting-edge enhancement is to provide post-quantum security to the whole RingCT protocol, by using lattice-based cryptography to redesign all algorithms.
