For the second yr in a row, the Chainlink workforce attended the ETHDenver Hackathon. The workforce labored across the clock supporting enthusiastic builders who needed to interface their sensible contracts with real-world information and techniques utilizing Chainlink powered decentralized oracle networks. The message of related sensible contracts is resonating; we noticed a few of the highest high quality hackathon venture submissions up to now at this premier Ethereum hackathon.
On the occasion, we introduced our ongoing work with Off-chain Labs for computing scalable solidity sensible contract off-chain utilizing Chainlink nodes, in addition to our collaboration with 0x on new DEX functionalities. Sergey delivered a robust speech about how Chainlink might help redefine the sensible contract business by shifting it past tokens. Product Supervisor Johann Eid gave a discuss “Securely Connecting Good Contracts to Off-chain Information Sources,” and Senior Partnership Supervisor Andrew Thurman represented on a panel dialogue about layer 2 expertise.
Hackathon members had 36 hours to construct the perfect working blockchain software potential. We awarded three bounties price $5,000 USD to the perfect working sensible contract functions utilizing Chainlink. Individuals demonstrated how data-driven enterprise fashions could be constructed on prime of decentralized infrastructure, that includes merchandise for parametric insurance coverage, multi-platform automated leverage buying and selling, and real-time attendance monitoring on-chain.
First Place: InsuraLink
Incomes the distinguished grand prize of $2,500 USD was InsuraLink, a 4 particular person workforce consisting of Aidan Tetther, Owen Evans, Raymond Mogg, and Patrick McNab from Safe Information Hyperlinks. As just lately demonstrated with Etherisc, parametric insurance coverage fashions through Chainlink oracle-enabled sensible contracts have immense potential to decrease the price of claims processing and open up public participation within the provide facet of insurance coverage.
InsuraLink is a modular framework for designing data-driven insurance coverage agreements that use Chainlink oracles to bridge IoT and sensible contracts. This permits real-world information collected by IoT units to be relayed to and set off insurance-based sensible contracts. The result’s automated execution of on-chain occasions, akin to declare payouts to policyholders, primarily based on real-world insurable occasions. Chainlink oracles play two key roles:
- Initiation – IoT sensors are used to watch environments for deviations occurring outdoors an outlined threshold, e.g. the temperature falling under a sure level. When deviations happen, the IoT units act as exterior initiators for triggering a Chainlink job. Initiators could also be depending on a number of occasions, akin to anomalies in all three classes: temperature, humidity, and G drive.
- Transportation– Chainlink nodes monitoring for log occasions, reply to the job with information from the desired IoT units. A number of Chainlink nodes are used to guard in opposition to a single level of failure. Customers can even tack on extra safety by initiating a number of callbacks for a similar information.
The workforce at Safe Information Hyperlinks acknowledged “The coordination prices of participating in insurance coverage contracts are lowered when utilizing the InsuraLink Market. This permits for customers in native and cross-jurisdictional networks alike to insure their friends. Dangers are subsequently localized, clear, and distributed amongst incentivized community stakeholders.” The workforce plans so as to add extra options sooner or later, akin to enabling customization choices for funds, dispute capabilities, multi-factor authentication of knowledge, and extra.
2nd Place: 1x.ag
Coming in 2nd place profitable a bounty of $1,500 USD was 1x.ag, a 4 particular person workforce of Sergej Kunz, Krill Kuznetcof, Nikita Kozlov, and Artem Vorobev. There’s a various vary of DeFi Dapps getting into the marketplace for lending, leverage buying and selling, and decentralized trade. 1x.ag is a Dapp that permits customers to construct leveraged commerce positions throughout totally different lending platforms from one consumer interface. Customers can incorporate automated buying and selling methods for managing their positions throughout platforms to cut back fuel charges, decrease slippage prices, and simplify the consumer expertise.
1x.ag goals to permit customers to concurrently faucet into loans from Compound, Fulcrum, Aave, and MakerDAO CDP’s with Aave flash loans. Customers can set cease losses to stop liquidation and take earnings when sure outlined value factors are hit, that are verified and routinely executed primarily based on sourced market information from Chainlink decentralized oracle networks. Anybody can name the liquidation or take revenue capabilities when it’s legitimate.
1x.ag leverages 1split.eth, an open-source on-chain aggregator created by 1inch.trade, when swapping underlying collateral by splitting up token swaps amongst a number of totally different decentralized exchanges, akin to Kyber, Bancor, MakerDAO/Oasis, and Uniswap. The workforce acknowledged that “Having outlined parameters when buying and selling is necessary to precisely hedge in opposition to value volatility. Chainlink oracles allow better hedging logic to be constructed into the sensible contract that permits our bot to precisely shut positions throughout platforms once they deviate outdoors the takeProfit and stopLoss limits.”
Choose’s Selection Award: We Watch in Public Areas
Successful the Judges Selection Award of $1,000 USD was We Watch in Public Areas, a two man workforce of Iain Nash and Evan Trumbull. Giant occasions are vital alternatives for companies to market and community with potential prospects. A substantial quantity of assets go into attending these occasions, making selecting the best ones particularly necessary. The issue is how do potential attendees know that the guarantees of occasion organizers – estimated attendance, sales space visitors, potential rewards, and so forth – are literally price their beneficial assets?
We Watch in Public Areas solves this downside of occasion transparency by making a blockchain monitoring system for calculating occasion attendance by monitoring high-traffic venue areas. A laser beam and IoT sensor monitor attendees on the entrance primarily based on the variety of instances the beam is crossed, whereas a low energy Bluetooth connection screens members all through the area. Attendance info from the sensors is securely relayed in real-time to the blockchain utilizing a number of Chainlink oracles. The workforce famous that “Chainlink simplified the dilemma of updating the information each N minutes and funding a course of to attain that.”
The top result’s elevated transparency of the occasion’s efficiency metrics, which could be simply verified by all events concerned. The workforce acknowledged that “With this monitoring system, we are able to create accountability to raised inform the pricing of ads, sponsor placement and engagement, and occasion ticket pricing.” This results in new contract constructions for dynamic billing primarily based on verifiable on-chain information, and might function an immutable previous efficiency foundation for negotiating future contracts.
All three functions showcase how sensible contracts turn into exponentially extra highly effective by securely interacting with off-chain information and techniques. We’re particularly intrigued by how they enhanced the power of customers to work together with DeFi, in addition to the seamless integration between sensible contracts and the vastly increasing world of IoT.
Should you’re a developer and need to join your sensible contract to current information and infrastructure outdoors the underlying blockchain, attain out to us right here! We might help you rapidly and securely launch your data-enabled software or Chainlink Worth Reference Information Contract on mainnet immediately.
