What Is a Zero-Knowledge Proof (ZKP)?

While the inherent transparency of blockchains provides an advantage in many situations, there are also a number of smart contract use cases that require privacy due to various business or legal reasons such as using proprietary data as inputs to trigger a smart contract’s execution. An increasingly common way privacy is achieved on public blockchain … Read more

Bringing Sports Markets to Blockchains Using Smart Contracts and Chainlink Oracles

The sports industry is on track to surpass $600 billion in value by 2022. One of the emerging trends for the sector is sports markets running on top of blockchains using hybrid smart contracts—tamper-proof blockchain applications that automate processes using traditional API data. These hybrid smart contracts bring many new opportunities to athletes, teams, leagues, … Read more

How Blockchain Technology Is Transforming the Real Estate Industry

Real estate, the largest asset class by value which is expected to grow from $2687.35 billion in 2020 to $3717.03 billion in 2025, is primed to be disrupted by the introduction of blockchain technology. Not only can real estate assets become digitized as tokens on blockchain ledgers, but smart contract developers can deploy on-chain logic … Read more

Hybrid Smart Contracts Explained

Hybrid smart contracts combine code running on the blockchain (on-chain) with data and computation from outside the blockchain (off-chain) provided by Decentralized Oracle Networks. Hybrid smart contracts enable advanced forms of economic and social coordination that have the tamper-proof and immutable properties of blockchains yet leverage secure off-chain oracle services to attain new capabilities, such … Read more

Redefining Trust Models With Chainlink’s Decentralized Services

With DeFi continuing to lock in more value and NFTs capturing the public imagination, the global economic system is starting to reach a turning point where everyday people can finally participate in secure digital agreements in industries as wide ranging as finance, insurance, gaming, and art. Smart contracts—digital contracts underpinned by cryptographic guarantees—are proving the … Read more

How the Chainlink Network Goes Beyond Data Delivery

Oracles are commonly thought of as blockchain middleware that enable smart contracts to access external data—yet oracle networks, as they exist within Chainlink’s model, are much more than data delivery mechanisms. Through a wide-range of off-chain computational abilities, Chainlink’s decentralized oracle networks are providing blockchains with decentralized services that go far beyond securely fetching external … Read more

What Is an NFT?

The most widely recognized application of blockchain technology is the creation of cryptocurrency, such as Bitcoin and Ether, which enables users to transfer value peer-to-peer without a rent-seeking middleman. Programmable smart contracts expanded upon this concept by empowering anyone in the world to create their own fungible tokens, such as stablecoins, commonly used in the … Read more

How Chainlink Enables Blockchain IoT Integrations

With the number of Internet of Things (IoT) devices expected to reach over 25 billion in 2021 and smart contract innovation now in full thrust, blockchain IoT applications have emerged as a compelling use case for combining the growing web of Internet-connected sensors with the secure automation of blockchain networks. IoT devices are physical objects … Read more
