This is the proof that you stopped by at the ENS booth at ETHGlobal Cannes. The Ethereum Name Service (ENS) is a distributed, open, and extensible naming system based on the Ethereum blockchain, and works across web3 and the whole internet. It's your identity: simple, memorable, unmistakably yours. For your hackathon project, you can leverage ENS to give names to Ethereum addresses and store user data directly on their ENS name, which acts as a interoperable profile. Or mint subnames for the users of your app. ENS is very powerful - trust your instincts as you enhance the user experience of your app.

This POAP means that you successfully minted a POAP during EthCC [8] Week. Thanks for being part of something innovative!
