Chainlink is driving the growth of the smart contract ecosystem by continuously bringing new datasets and off-chain resources on-chain, broadening the number of use cases.

Chainlink Price Feeds incorporate three levels of data aggregation in each price update on-chain: at the data source, node operator, and oracle network level.

Decentralized money markets enable users to borrow and lend their crypto assets in a permissionless manner. In this article, we explore how DeFi money markets work and why they need secure price feeds.

Chainlink Proof of Reserve provides on-chain smart contracts with definitive truth on the collateralization of tokens backed by off-chain assets commonly used in DeFi as collateral.

Blockchain-based game Axie Infinity is using the Chainlink Network’s tamper-proof price feeds and verifiable randomness to unlock a new economic model for players worldwide.

Through the combination of Bitcoin and Chainlink, innovative on-chain and off-chain financial products can be created that leverage the unique properties of Bitcoin, without requiring any changes to the Bitcoin blockchain itself.

As the DeFi ecosystem grows, there is an increasing incentive for malicious actors to exploit vulnerabilities. In this post, we walk through flash loan funded oracle attacks and how to prevent them.

We've developed a novel price oracle with Synthetix to power sOIL, a synthetic oil derivative. This is another example of how Chainlink bringing traditional financial assets to DeFi.

Digital Identity (D-ID) is a critical component of the Internet experience. We examine the risks and challenges with legacy D-ID implementations, introduce innovative blockchain D-ID solutions, and analyze how Chainlink oracles play a key part in connecting personal information to the blockchain.

Chainlink’s Price Feed visualizations promote transparency across the DeFi space by showcasing the composition and real-time performance of decentralized oracle networks that feed price reference data to smart contracts.

Demand is growing in global markets for security and transparency around financial transactions. Here’s how Chainlink’s oracle networks are accelerating DeFi and helping existing systems connect to trusted, decentralized infrastructure.

The Chainlink Network is made of a growing collection of secure node operators who power decentralized oracle networks across a multitude of blockchains. Through numerous interfaces, developers can discover these nodes and use them to power their unique decentralized applications.

Yield farming is the newest phenomenon within DeFi that financially rewards users for providing a service to the protocol, typically through the provisioning of liquidity within a decentralized application's ecosystem.

Asset tokenization can help investors access cloistered investment opportunities, reduce transactional friction, increase transparency, and connect real-world value to DeFi, but needs secure oracles to function.

DeFi composability on the blockchain enables a new generation of decentralized applications built upon interoperable, permissionless financial money LEGOs.

As the field of blockchain-based gaming grows and expands, randomness and RNG will become an increasingly powerful economic force for both developers and players.

Smart contracts are exponentially more powerful when externally connected to the data and API economy outside the blockchain. Tapping into these vast data reservoirs can make smart contracts the dominant form of digital agreement across all the major markets.

Automated Market Maker (AMM) based Decentralized Exchanges (DEXs) alter how users swap cryptocurrencies. We explore how AMMs work, dissect their inherent problems, and examine solutions to solve these key obstacles.

Smart contract—a software program on the blockchain with conditions attached to its execution. In this article, we examine what a smart contract is, why it is valuable, and how it is being applied today.

Chainlink oracles enable developers to create dynamic NFTs on the blockchain that react to external data and fully integrate with existing infrastructure.

Blockchain is the foundational technology that underpins the value proposition of Bitcoin and Ethereum smart contracts. This article describes what is a blockchain, why it provides value, and how it is being used today.
