According to TechFlow, Manta Network announced the launch of NPO (NFT Private Offering), a privacy NFT/SBT issuance platform based on zero-knowledge proof (ZK). NPO is built on the ZK circuits of zkAddress and MantaPay. Manta Network abstracts the complexity of ZK. Developers do not need to understand technology or cryptography knowledge. They can issue privacy NFTs and SBT by using SDK. zkNFT and zkSBT have the same ease of use as NFT/SBT, and are plug-and-play. Developers can connect them with Web2 App or Web3 DApp, thereby binding on-chain information to off-chain applications through ZK Proof Key to create new applications. Original link
