Open-source software is the driving force behind Ethereum's decentralized infrastructure, supporting the growth of on-chain digital assets and securing billions in DeFi smart contracts. Chainlink actively funds Ethereum developers and the smart contract ecosystem through Gitcoin donations, bug bounties, and hackathons, while offering financial support to development teams and researchers. It participates in Gitcoin's quadratic funding rounds to equitably distribute funds to community-selected projects, fostering infrastructure development and ensuring the smooth operation of decentralized applications. Ethereum and other blockchain ecosystems provide a new backend infrastructure with decentralized smart contracts, transforming socio-economic models and enabling various applications such as NFTs, insurance, and gaming. Chainlink aims to continue supporting Ethereum's infrastructure through innovative decentralized oracle solutions and funding platforms like Gitcoin.
