At the ETHDenver Hackathon, Chainlink's team actively supported developers in integrating their smart contracts with real-world data through decentralized oracle networks, culminating in high-quality project submissions. Chainlink announced collaborations with Off-chain Labs for off-chain computation of Solidity smart contracts and with 0x for new decentralized exchange functionalities. The hackathon featured a 36-hour challenge, awarding $5,000 in bounties to top projects utilizing Chainlink, such as InsuraLink, which won first place for its parametric insurance framework linking IoT data to smart contracts. Other notable projects included 1x.ag, a Dapp for leveraged trading, and We Watch in Public Spaces, a blockchain-based event attendance tracker. These projects demonstrated how smart contracts can be enhanced by securely connecting with off-chain data, showcasing the potential of decentralized finance and IoT integration.
