A social graph is a framework of interconnections between entities, including people, organizations, and things (such as protocols), typically derived from traceable social network connections.
When illustrated, social graphs resemble maps of network nodes. In blockchains, social graphs may be constructed by examining historical on-chain activities between wallet addresses and smart contracts.
Social graphs may provide economically valuable insights, such as predictive consumer behavior insights extrapolated by tech companies when analyzing user data. Using cryptographic tools such as decentralized identities, some blockchain projects seek to capture this valuable data so that users may monetize their own data instead of freely 'giving' it away to centralized institutions.
