Mapping The New Internet

Blockchain networks will need on-chain identity, much as the internet did, because market incentives drive Sybil attacks and retail applications face regulations requiring more user information. Current identifiers such as wallet addresses, NFTs and wallet labels from Degenscore and Nansen are weak, since wallets can be created with a click and NFTs show little about their holders' accomplishments. Vitalik Buterin proposed soulbound tokens, which are non-transferable and must be accepted by the user, so issuers such as universities and attesters can verify a claim, such as a claimed job at McDonald's.
