I highly recommend “Decentralized Society: Finding Web3’s Soul,” a paper co-written by E. Glen Weyl, Puja Ohlhaver, and Vitalik Buterin, in which authors raise multiple cases to illustrate how a decentralized society is functioning. Very foresightful and insightful. As I raised before, ERC-20 is the foundation of DeFi and ERC-721 is the foundation of NFT. To push Social-Fi, Game-Fi, or general Web3 applications to a higher level, we need to have something similar to “soulbound” tokens (SBTs) mentioned in the paper. SBTs are tightly bounded to user identity and take along user behavior-related data. In the paper, the authors point out that there are still many problems left for building SBT, including programmable privacy and community recovery. We still have a very long way to go. However, the potential applications of the standard listed in the paper still arouse my sympathy.
