How does PGP work web of trust?

In cryptography, a web of trust is a concept used in PGP, GnuPG, and other OpenPGP-compatible systems to establish the authenticity of the binding between a public key and its owner. This will cause the emergence of a decentralized fault-tolerant web of confidence for all public keys.

Is PGP decentralized?

We present KeyChains, a decentralized public key infrastructure based on the PGP web of trust model. PGP has been a popular way for email users to exchange public keys without resorting to a centralized certification authority (CA). In PGP, users both generate their own keys and certify each other’s keys.
