Mercle
Identity and reputation data layer for the internet.

What is Mercle?
Mercle's vision is to create a decentralized web3 identity/reputation data layer for web3 dapps. It allows dapps to issue attestations for both on-chain and off-chain user activities. The architectural core of Mercle provides a foundation for decentralized identities, which can be used for better governance, efficient coordination, smart token rewards distribution, and even as a reputation tool, where any dapp can tap into Mercle to determine a web3 user's reputation, globally as well as in a certain community.
