DIDs and all textual IDs (e.g. ENS) cannot enclose a digital identity on its own. This is an immanent disadvantage of linguistic signs. Not only social relationships (such as SBT) but also visual representation (e.g. PFP NFT) are needed to build a digital-native identity. In this article, representation is given a new name as 'cyber flesh'.

KYC is not the only ‘inevitable’ choice for verifying on-chain identity, and a ‘passport’ is not a proper form of personal document under a decentralized ethos

GALXE推出的护照服务引起了社区关于身份证明是否需要KYC的争议。本文试图论证：（1）链上数据提供了很多种身份验证的途径，KYC并不是唯一的无奈决定；以及（2）为什么web3的数字身份不需要“护照”这种身份文件形式，以及该种文件的原生缺陷与隐含风险。

DID以及所有字符ID（如ENS）不可能独立定义一个数字身份，这是语言符号的原生限制。DID必须需要配合社交关系（如社区贡献代币）以及视觉表达（如PFP NFT）才能建立一个原生的数字身份。本文将后者，数字身份的视觉表达命名为“数字血肉 cyber flesh”。

QF function can be applied to rather allocate a pool of communal attention to filter certain categories of news out from the great turbulent ocean of information.
