Honeycomb Smart Contract Hackathon is a three-week virtual hackathon focused on connecting the world of smart contracts and decentralized applications to real-world data from some of the world’s premier data providers. 

Using Honeycomb’s broad list of APIs connected to the Ethereum blockchain through Chainlink oracles, developers will be able to enrich their smart contracts with data from categories like crypto, forex and traditional market rates, weather, sports scores and odds (for both traditional and e-sports), flight schedules and more. For data-aggregation, developers will be able to connect to the entire catalogue of Honeycomb APIs through multiple reliable Chainlink oracles, or use the free Honeycomb Ropsten testnet oracle.

The hackathon starts on Wednesday, November 20th, and participating applications should be submitted through Devpost by Wednesday, December 11th, 11pm ET. 

APIs available for hackathon participants: 

Eligibility

Participants need to be over 18 years of age, and adhere to the hackathon rules. 

Requirements

What Should I Build?
We encourage developers to create applications that make them excited about the future of smart contracts and decentralized applications. 

All submissions need to include an integration of at least one Honeycomb API
Smart contract applications submitted for the hackathon need to include a state change that is executed by a data input from at least one Honeycomb-listed API through at least one Chainlink oracle (mainnet or Ropsten). Honeycomb provides developers with free access to API test calls through a Ropsten testnet oracle.

How to join:

1. Register for the hackathon here on Devpost by clicking the green button (top right on this page)

2. Create a Honeycomb account at honeycomb.market

3. Come up with an idea for a cool smart contract application (consider requirements and judging criteria, some inspiration here)

4. Build your cool smart contract application (see documents, resources and tutorials below)

5. Submit, at minimum, a link to your application + a description of the application through Devpost before December 11th 2019, 11pm ET (you may also provide additional information in the submission, such as a link to a video showcasing the application)

Judging Criteria

  • Honeycomb Smart Contract Hackathon Top 3:
  • Real-World Applicability
    Does the submission demonstrate real-world applicability by including a practical business model, a strong user-value adding feature, or possibly a viral engine that makes the application relevant for users beyond just the crypto sphere?
  • Functionality, User Experience and Design
    Does the submission function as described? Is it well designed in both its user experience and appearance?
  • Input Combinations and Aggregation
    Smart contracts featuring creative combinations of several different API data inputs, or using aggregation to combine inputs from multiple APIs into a single data point earn bonus points from the judges.
  • Judge's Choices by Chainlink:
  • Use of Chainlink Oracles
    You must successfully use Chainlink oracles, and the data fetched by the oracle must trigger a state change in the smart contract.
  • Data Treatment
    You must share how you treat this retrieved data. For example, do you use a median, weighted average, or some other aggregation formula?
  • Decentralization
    It is preferred, but not required, that the data used will be collected from multiple oracles to show the decentralized application of Chainlink.
