How Bulletproofs Could Make Bitcoin Privacy Less Costly
Bulletproofs, presented in a paper titled Bulletproofs Short Proofs for Confidential Transactions and More, describe a new zero-knowledge proof system. The proposal uses on-chain scaling for privacy and suggests a new, faster and more compact way to verify privacy-enhancing Confidential Transactions CTs. Specifically, Bulletproofs can decrease the size of these verifications for these types of transactions drastically. Furthermore, the authors of the paper Stanford Universitys Applied Crypto
