Chainlink participated in the ETHParis Hackathon and awarded prizes to the teams with the best working applications of Chainlink on the Ethereum blockchain. Initially, there were plans to award only one $1,000 prize. However, given the amazing submissions, the judges decided to award another prize for the second place team.
The second place prize of $500 USD in LINK was awarded to SmartKek, a four-person team from Russia, including members Evgeny Marchenko, Pavel Kondr, Sergio Pavlin, and Alex Levin. Their Cleanedapp Dapp enables anyone to post a write-up about a token, only after they burn a portion of that specific token. Combining crypto-economic incentives with mechanical burning, the more tokens someone burns, the more words they're allowed to write in their post. Burning tokens removes them from circulation by sending the tokens to a burn address - a public key with no known or discoverable private key.
Cleanedapp uses Chainlink oracles to feed the smart contract different data metrics, such as the amount of on-chain transactions or distribution of tokens, to ensure a project is authentic. The Cleanedapp team stated that "The oracle determines if the token is real, so you can't spam the network by using a token specifically for this purpose." Having reliable data feeds ensures higher quality posts from people involved in verifiable projects.
Earning first place honors of $1,000 USD in LINK was Nanti, a local two-man French team of Xavier Lavayssière and Alexandre Kurth. Nanti is a Dapp that allows companies to issue and use corporate bonds as collateral for instant payment channels. Nanti facilitates tokenized bond issuance on private networks compatible with Ethereum, such as Quorum. It also offers quick access to liquidity for bond owners who want to use the bond as collateral.
In order to accurately calculate bond payments, Nanti uses Chainlink oracles to retrieve the LIBOR rate — a global standard of the average interest rate used for interbank lending in the London market. The LIBOR rate is the off-chain input that triggers the on-chain contract to issue an output in the form of a bond payment.
Congratulations to the ETHParis Hackathon winners! Both projects demonstrated how on-chain smart contracts can be reliably triggered by off-chain data that is securely delivered using Chainlink oracles. By allowing smart contracts to interact with off-chain resources, Chainlink has created a much-needed bridge between the legacy world and the blockchain world.
Join us for evening Meetup featuring an interactive panel discussion during EDCON 2019 Chainlink, Parity, and Zeppelin.
We will be demonstrating a chainlinked smart contract that utilizes Wanchain's cross-chain capability. This combines the idea of Chainlink's cross-chain data and inputs with Wanchain's cross-chain transactions.
