Weekly Wrap: This Week In Chainlink February 22 - February 28
Huge week for the Chainlink network this past week! Take a look at the exciting stories including the launch of OCR, VRF on Polygon, and Announcing the Chainlink Hackathon!
Announcements and Integrations ?
We’re excited to announce the Spring 2021 Chainlink Hackathon! Join us from March 15th - April 11th to compete for over $80k in bounties by building smart contract applications using Chainlink oracles. #BuildWithChainlink
Off-Chain Reporting is now live on mainnet, marking a major scalability upgrade of Chainlink’s oracle network. OCR reduces on-chain gas costs by up to 90% & enables Chainlink to bring 10x more data on-chain, accelerating DeFi & smart contract innovation. OCR is the newest version of the Chainlink core client, which Chainlink nodes will run in parallel with FluxMonitor for multi-client diversity. OCR’s model of off-chain computation enables oracles to cost-effectively feed secure data on-chain for smart contract consumption. For those wanting an in-depth technical overview of the design goals, computer science, and report generation process behind Chainlink Off-Chain Reporting, we encourage you to read the OCR protocol paper linked below. https://chain.link/ocrpaper
- Chainlink VRF Is Live on Polygon, Providing Developers With a Secure Source of Verifiable Randomness
@0xPolygon integrates Chainlink VRF on mainnet as its recommended solution for developers needing secure & fair randomness. This enables gaming dApps like @EtherLegends to cost-efficiently scale & enrich in-game scenarios on Polygon's layer 2 aggregator.
@aavegotchi is using Chainlink VRF on the @0xPolygon mainnet to assign traits to Aavegotochi NFTs in their Portals game. Aavegotochi plans to make 10,000+ calls in the first few weeks thanks to Chainlink VRF running natively on Polygon's layer-2 network.
@dydxprotocol is using Chainlink Price Feeds in its Alpha launch to secure lending & margin trading operations. By integrating with Starkware, the Chainlink Network has extended its hyper-reliable oracle functions to high-performance Layer 2 solutions.
Blockchain platform @Sperax_io is using Chainlink VRF on the Ethereum mainnet to select random block heights in a verifiably tamperproof & unbiased manner. These randomly selected block heights will determine when a series of airdrops to users will occur.
Multi-chain DEX aggregator @ZeroSwapLabs is integrating Chainlink VRF to randomly select winners on the ZeeDO token offering platform. VRF enables provably fair selection, ensuring secure & transparent token events as ZeroSwap grows to support more chains.
Premium data provider @worldweatheronl will launch their own Chainlink node to provide developers across leading blockchains with cryptographically signed weather data, supporting new blockchain-based weather markets in parametric insurance & derivatives.
@DollarProtocol is using the Chainlink CNY/USD Price Oracle on mainnet to determine rebases for their newest algorithmic stablecoin CNYx. Chainlink's high-quality data and decentralized infrastructure ensure both accurate & tamperproof supply adjustments.
Algorithmic money market @MultiplierMXX is using Chainlink on Binance Smart Chain to price crypto-assets during loan operations. With wide market coverage across both CEXs and DEXs, Chainlink oracles ensure Multiplier obtains global volume-adjusted prices.
@GeoDataBlock has launched their own Chainlink node live on mainnet to make mobile location data available on-chain. This provides foot traffic info from physical retail stores that can be leveraged to build dApps like location-based marketing & games.
With the recent launch of Cosmos's inter-blockchain communication protocol (IBC), @kava_labs will expand its integration with #Chainlink by using IBC to make Chainlink's high-quality price feed data available to any blockchain within the @cosmos ecosystem.
.@ichifarm integrates Chainlink into their development stack to enable crypto communities to develop their own stablecoin. This allows partial collateralization of stablecoins with their native tokens, leveraging Chainlink in the minting/redeeming process.
IoT automation platform @NetObjex is using #Chainlink to bring IoT data on-chain & trigger smart contracts around real-world sensor readings, enabling novel use cases like token rewards for travelers who consume less water & energy at IoT-connected hotels.
We are thrilled to announce that the #Chainlink Bug Bounty Program on @gitcoin and @Hacker0x01 has been expanded to provide $100K for the responsible disclosure of any critical vulnerabilities, further increasing the robustness of the Chainlink Network.
What’s New for Developers ?
Off-Chain Reporting (OCR) is an order of magnitude improvement in the scalability of the Chainlink Network. Learn how OCR offers 10x more data delivery throughput by lowering gas costs of oracle updates by 90% while maintaining cryptographic guarantees.
With the launch of Off-Chain Reporting (OCR), a scalability upgrade that reduces network operating costs by up to 90%, #Chainlink is increasing the decentralization of its price oracles. Integrate the LINK/USD OCR Price Feed on mainnet today to ensure the security of your dApp.
Chainlink provides a full suite of oracle solutions to accelerate #stablecoin adoption, including several live oracles for @TrustToken’s TUSD that DeFi applications can integrate today, such as the TUSD/ETH Price Feed, the TUSD on-chain supply, and the TUSD off-chain reserves.
