BrightID is a decentralized identity verification platform that is designed to prevent Sybil attacks (where one person creates multiple accounts to manipulate a system). Users can connect their social media accounts to their BrightID profile, which is then verified by other trusted users in the network.

By forming connections with other verified users, a trust score is established for each individual on the platform. This trust score helps users establish their credibility and authenticity within the network. BrightID aims to create a web of trust where users can easily verify each other’s identities without the need for centralized authorities.

In the world of cryptocurrency, BrightID is used to ensure that individuals participating in decentralized applications or protocols are real and unique. This helps mitigate fraudulent activities and maintain the integrity of the network. By incorporating BrightID into decentralized ecosystems, users can interact with confidence knowing that other participants are legitimate.
