Token Curated Registry (TCR) is a decentralized system where participants manage a list using voting tokens. To add an item, a user contributes tokens and other participants vote for or against its inclusion. This process helps filter out untrusted items because each participant risks tokens if their vote is not supported by the majority.
This model helps create high-quality and objective lists, for example with projects or services, where the community controls and maintains their relevance and reliability.
