What is Mercle?
Mercle is a decentralized web3 identity and reputation data layer that allows dapps to issue attestations for both on-chain and off-chain user activities. Its architectural core provides a foundation for decentralized identities, which can be used for better governance, efficient coordination, and smart token rewards distribution. Mercle also serves as a reputation tool, where any dapp can tap into Mercle to determine a web3 user's reputation, globally as well as within a specific community.
