Overview
A web of trust is a decentralized trust model where individuals vouch for each other's identities. Trust propagates through connections rather than a central authority. It predates blockchain and is used in some identity systems.
How It Works
Users sign each other's keys or credentials, and trust is derived from the network of signatures. If you trust someone, you may trust those they vouch for. This creates a distributed trust graph.
Why It Matters
A web of trust provides decentralized identity verification without a central issuer. It aligns with self-sovereign principles. Its adoption has been limited by usability and sybil challenges.
