Enigma is a privacy protocol to enable privacy preserving smart contracts on Ethereum. Enigma utilizes secret contracts - smart contracts that let you use private and sensitive data in decentralized applications. Enigma is building a network for privacy preserving computations. Nodes in the Enigma network that execute secret contracts never see the data that is used in their computations.
Blockchain technology has realized the mapping of currency in the digital world, and has produced a series of homogenized encrypted digital currencies, which has created a wave of investment in encrypted currencies in recent years. Rather than the emergence of non-homogeneous token NFT, we see the possibility of mapping the entire real world. The characteristics of NFT can perfectly adapt to this situation and realize the generalization of different objects in the digital world. However, due to the current technical bottleneck, NFT has not been able to achieve the above-mentioned idea perfectly.
