论文摘要
如今，NFT市场上可用的智能合约的许多实现允许修改NFT令牌属性，而没有任何特定机制来控制与链元元数据的一致性。我们认为，这是当今NFT的整体设计的弱点。我们提出了一个称为资产代理NFT的计算模型，该模型保证了NFT令牌（链上）及其相应的资产元数据（链）之间的一致性。通常，所提出的模型可以应用于需要不变性或受控元数据可控性的任何类型的NFT。本文的第二个贡献是NFT设计模式的概念，该模式认识到需要处理混合资产的连贯框架，并且对于特定的混合资产部署，必须在框架下使用合适的技术组件。
Many implementations of smart contracts available in NFT marketplaces today allow the modification of NFT token attributes, without any specific mechanism to control the consistency with off-chain metadata. We believe this is a weakness in overall design of NFTs today. We propose a computation model called the Asset Proxy NFT that guarantees the consistency between the NFT token (on-chain) and its corresponding asset metadata (off-chain). In general, the proposed model can be applied to any type of NFT that requires immutability or controlled mutability of metadata. A second contribution of this paper is the notion of the NFT design patterns which recognizes that a coherent framework for dealing with hybrid assets is required, and that for specific hybrid-asset deployments, suitable technological components must be utilized under the framework.
