SERO (Super Zero) is the world-leading technology with SUPER Zero-Knowledge Proof that truly implements blockchain privacy protection and a public chain platform that supports smart contract operation.SERO is the world’s first cryptocurrency technology to achieve complete privacy protection and to support smart contracts through Zero-knowledge proof. Zero-knowledge proof used by SERO is reviewed and approved by professional organizations. The protocol is built on the latest cryptography studies that greatly improves performance and security. Added privacy protection to the entire transaction sequence of cryptocurrency on the blockchain. Account information and transaction amount are no longer transparent to the entire network; aligning user privacy needs with actual consumer scenario. SERO has developed Super-ZK — Zero-knowledge Proof encryption library, independently developed by SERO which is currently the fastest in encryption performance. In the same application scenario, Super-ZK encryption speed is 20 times faster than Zcash (the mainstream privacy protection cryptocurrency that at present, uses zk-SNARKs). Compare with Bulletproofs (the latest bulletproof protocol), Super-ZK is 4 times faster. SERO solved the Zero-knowledge proof performance problem. SERO will lead the privacy protection space and the preparation for the wider commercialization of blockchain.
