SheBuilds - Concordium Hackathon

Bounty

 

Building the future of identity. Create the foundation for the next generation of use cases which have ID, privacy and accountability at their core.

 

Concordium will be giving away a total cash prize of $550 for the best hacks built during the hackathon. Integrating the ID will get you extra points! 

  • $300 for 1st 

  • $150 for 2nd 

  • $100 for 3rd 
     

Examples

​

Examples of dApps and tooling which could be built. Feel free to use this as inspiration rather than being constrained by only developing the things on this list. 

​

  • Timestamp application: User can connect with his web wallet, upload data and store the hash value of it on Concordium. There should be a default address to make the transaction as an alternative option if he doesn't want to sign it.
     

  • Transfer CCD with age check: Implement a dApp that checks the user's age is older than 18 before placing the transaction.
     

  • Implement a simple P2E game: Implement a very simple dice game that allows players to lock some CCDs in a contract and pays after someone wins.
     

  • Implement a rental NFT Contract: Implement a smart contract that allows people to rent an NFT for some time for some CCDs. If time expired, NFT transfer back to the original owner from user. Use concordium-client to test it and document it to showcase all steps.
     

  • Implement a soulbound token Contract: Implement a smart contract for SoulBound tokens. A soul bound token is a special form of an NFT that can not be transferred but revocable and expirable. Use concordium-client to test it and document it to showcase all steps.
     

Bonus: Build a front-end to showcase these use-case.

​

These are just ideas - use your imagination and build something that excites you and is a powerful use case!
