What is Chainlink?

What is Chainlink?

Chainlink is a blockchain abstraction layer that enables universally connected smart contracts. Through a decentralized oracle network, Chainlink allows blockchains to securely interact with external data feeds, events, and payment methods, providing the critical off-chain information needed by complex smart contracts to become the dominant form of digital agreement.

What is a blockchain oracle?

What is a blockchain oracle?

A blockchain oracle is any system that services a smart contract by providing it with data from an off-chain source or connecting it with an off-chain system. Oracles enable connectivity between blockchains and real-world data by interfacing with external APIs and data feeds, allowing them to pull data for or push data from a smart contract.

Why do blockchains need oracles?

Why do blockchains need oracles?

Oracles allow smart contracts to interact with real-world data from off-chain sources. Without oracles, smart contracts can only access data generated on the blockchain, severely limiting their potential applications. Most of the valuable real-world use cases for smart contracts require off-chain data to trigger proper execution and often an integration with existing payment rails to settle a contract. For example, a smart contract may require market data from a trusted source like the NYSE to trigger a transaction. It may also require the ability to pay out escrowed fiat currency through legacy financial infrastructure, such as a bank checking account.

What is "real-world data"?

What is "real-world data"?

Real-world data, also known as off-chain data or external data, refers to the current global data infrastructure that exists outside of the blockchain that must be brought on-chain via oracles to be used by smart contract applications. Like a computer without the Internet, blockchain-based smart contracts have inherent value on their own, such as creating and swapping tokens. However, they become exponentially more powerful when externally connected to the vast and accelerating data and API economy taking root outside the blockchain ecosystem.

What is the oracle problem?

What is the oracle problem?

The oracle problem, also known as the “smart contract connectivity problem”, refers to a blockchain’s inability to natively pull data from or push data to any external off-chain system due to the strong security properties created by a blockchain’s consensus mechanism. 

Blockchain nodes are designed to perform standardized and uniform operations to generate consensus on a set of transactions (solving the double-spend problem). However, they are not suited to answer subjective questions about probabilistic real-world data, as blockchain nodes do not always have access to the same information, making generating consensus on even the most basic data requests challenging and source quality enforcement impossible. It is for this reason blockchains focus on generating definitive truth about the validity of transactions, but limit connections to any off-chain systems to ensure the network always remains live and produces deterministic results for incoming transactions. 

In order to create a bridge between the blockchain (on-chain) and the outside world (off-chain), there requires an additional and separate piece of infrastructure known as an “oracle”. However, the use of a centralized oracle can result in manipulated data inputs and outputs, meaning the oracle mechanism itself needs to be highly decentralized to ensure the security of a smart contract’s execution is maintained end-to-end.

What is the Chainlink Network?

What is the Chainlink Network?

The Chainlink Network refers to all of the decentralized oracle networks actively operating using the Chainlink protocol, including individual oracles, data providers running their own node, and node operators. By enabling smart contracts to quickly and securely connect to off-chain data sources using decentralized oracle networks, the Chainlink Network helps developers build more robust and diverse blockchain applications using real-world inputs and outputs. Additionally, as middleware between low-level blockchain protocols and external, off-chain data sources, the Chainlink Network serves as an abstraction layer for data providers to easily sell their existing APIs to any blockchain network.

What is a decentralized oracle network?

What is a decentralized oracle network?

A decentralized oracle network consists of multiple blockchain oracles run by independent node operators that are chosen to retrieve and validate data from several different off-chain sources. Each of the oracles’ responses within a decentralized oracle network are aggregated together to form a single trusted data point, which can be used to trigger smart contracts on any blockchain and really any system that needs highly reliable data that’s provably accurate. The data delivered on-chain can be hosted in a Reference Contract (pull model), and/or delivered directly to consuming smart contracts (push model). 

Chainlink’s Oracle Network is made up of multiple decentralized oracle networks running simultaneously and independently of one another. For example, if a smart contract requires data about the price of ETH, instead of relying on one individual blockchain oracle to pull price data from one API source, the smart contract can use a decentralized oracle network to have tens to hundreds of individual oracle nodes pull data from several API sources and then aggregate the result. See here for a live visualization of this data on-chain.

Through decentralized computation, Chainlink-powered decentralized oracle networks provide users superior security and reliability guarantees on the inputs and outputs of their smart contract, ensuring that both on-chain and off-chain components of a decentralized application are tamper-proof end-to-end.

What is a node operator?

What is a node operator?

Node operators are the entities that maintain and run the blockchain oracles that make up each Chainlink Oracle Network providing smart contracts on various blockchains access to external data and resources. These operators consist of professional validators for various blockchain networks, teams of highly experienced DevOps engineers, and organizations that focus specifically on building infrastructure for the Chainlink ecosystem. Additionally, external data vendors and API providers can monetize their data sets by running a Chainlink Node and providing signed data directly to smart contracts. Node Operators are able to configure their blockchain oracle node to connect to any off-chain data source and on-chain blockchain environment, providing a high degree of flexibility. 

Node operators within the Chainlink Network strictly adhere to the best security practices and use external monitoring systems to ensure a secure and reliable operation is maintained around the clock. Third-party marketplaces like market.link and reputation services like reputation.link provide users insight into the current and historical performance of each individual node operator. Additionally, anybody can become a Chainlink node operator, as no permission is required, and immediately begin providing smart contracts access to off-chain data. If you are interested in running a node, please navigate to our documentation here.

Why choose Chainlink to aggregate data for a smart contract rather than building one’s own oracle?

Why choose Chainlink to aggregate data for a smart contract rather than building one’s own oracle?

Chainlink provides users with a simple to integrate and pre-built decentralized oracle solution that can be utilized today by any smart contract on any blockchain. A Chainlink integration allows developers to focus on their application’s core business logic without needing to allocate precious resources to rebuilding infrastructure. Rolling your own oracle is extremely difficult and probabilistic as the oracle problem is complicated, technical, nuanced, and requires constant monitoring, upkeep, funding, and resources to maintain properly.

The ability to easily integrate a project with Chainlink’s decentralized oracle network has enabled numerous teams to avoid the hassle of building their own oracle, allowing them to instead focus on innovating and building use cases. Additionally, as Chainlink users collectively fund oracle networks as a public good, the costs of using Chainlink are far lower than attempting to build and manage your own solution. For example, a growing list of DeFi applications now use and collectively fund Chainlink price feeds. If you are interested in integrating with Chainlink, please reach out.

How does the Chainlink Network access high-quality data?

How does the Chainlink Network access high-quality data?

Chainlink nodes can access any authenticated or premium data source API through the use of modular external adapters. External adapters can be written in any programming language and hosted as a serverless function on any cloud provider or web server. These adapters allow Chainlink nodes to access a wide array of data sources, including authenticated and private APIs that require sensitive password keys, such as enterprise backends and subscription-based sources. Thus, Chainlink nodes have a high degree of flexibility as API credentials can be kept off-chain and stored securely, separate from the node itself.  

What are the benefits of having multiple layers of data aggregation?

What are the benefits of having multiple layers of data aggregation?

Chainlink oracle networks operate using multiple layers of data aggregation to ensure there is no single point of failure or any reliance on a single source of truth that could be corrupted. This redundancy is not only required to ensure high value smart contracts consume highly refined data, but also to ensure Chainlink Price Feeds provide full market coverage that reflects the true market price of assets. With Price Feeds securing billions in user funds, these layers of aggregation secure the DeFi ecosystem.


Layers of data aggregation in the Chainlink Network

Chainlink uses multiple layers of aggregation to ensure broad market coverage and data quality. 

The first aggregation layer is at the data source level where professional data aggregation firms (e.g. BraveNewCoin, CoinGecko) fetch market data from hundreds of exchanges, taking into account volume and liquidity differences, and generate a single weighted reference price point. The second aggregation layer is at the node operator level where each individual Chainlink oracle node sources price data from multiple data aggregation firms and takes the median, mitigating outliers, API downtime, and ensuring nodes do not rely on any one source. The third aggregation layer is at the oracle network level where the responses from multiple oracle nodes is aggregated by taking the median, ensuring no individual node has control over the resulting data point delivered to contracts. All of this together ensures smart contracts consume only the highest quality data that reflects the true market wide price.

For more information on secure oracle design, refer to our articles on the importance of data quality for DeFi smart contracts and the three levels of data aggregation in Chainlink Price Feeds. 

What affects an oracle's reputation score?

What affects an oracle's reputation score?

The original Chainlink White Paper outlines initial parameters for rating a node’s reputation: total number of assigned requests, total number of completed requests, total number of accepted requests, average time to respond, and amount of penalty payments. 

Secure Data Links’ Chainlink Oracle Reputation system collects and tracks these parameters to rate nodes: total transactions, job completion ratio, average gas price per transaction, sum of gas prices within a 10-minute window, average gas used per transaction, total gas used in a 10-minute window, average response time in blocks, total response time in a 10-minute window, average response time in seconds, and total response time in seconds within a 10-minute window. The system is consistently being enhanced with new services and features.

Where can I explore the performance and reliability of the Chainlink Network?

Users can use this data to filter and analyze each node’s revenue, gas costs, and response times. Developers can also query the Chainlink Market’s Metrics API to access all of this raw data themselves and build their own analysis framework using real-time data regarding the performance of the Chainlink Network.

Secure Data Links’ Chainlink Oracle Reputation site Reputation.link allows users to inspect an individual node operator’s performance statistics, including average response time, job completion ratio, and total LINK earned. Users can also get a high-level overview of the various metrics regarding the Chainlink Network over the past seven days such as the total number of requests, price feeds, oracle nodes, payments, average response time, and more.

How will Chainlink scale?

How will Chainlink scale?

Through off-chain reporting and Threshold Signatures, Chainlink oracle networks can scale to thousands of secure nodes within a network. Instead of each node making their own on-chain transaction for each update, node responses are aggregated off-chain, and only a single transaction needs to be submitted on-chain. The security of data is cryptographically maintained throughout the entire process. This allows for the creation of Chainlink networks that are highly decentralized while remaining cost-efficient and secure against manipulation through a defense in depth approach. Additionally, unlike other oracle projects, each Chainlink oracle network is entirely independent of one another and does not affect the scalability or throughput of any other Chainlink network. 

What is Chainlink Off-Chain Reporting (OCR)?

What is Chainlink Off-Chain Reporting (OCR)?

Off-Chain Reporting (OCR) is the third and latest version of the Chainlink Core software client run by Chainlink nodes, which significantly improves the efficiency of how data is aggregated by Chainlink oracles. OCR reduces operating costs by up to 90% and enables the Chainlink Network to generate a 10x increase in the amount of secure, real-world data available to smart contract applications. 

OCR allows Chainlink nodes to communicate off-chain and aggregate data at zero gas costs using a distributed, peer-to-peer network. In OCR’s computation model, each node fetches data from one or multiple data sources, signs it with their unique private key, and broadcasts it to the rest of the oracle network off-chain. Once a sufficient number of responses have been generated, a single transaction is transmitted on-chain containing every node’s observation. The oracle report and node signatures are then validated on-chain by a smart contract, providing the transparency and end-to-end security guarantees that are fundamental to Chainlink oracle networks. 

All Chainlink nodes operating in-production run the OCR and FluxMonitor clients in parallel to achieve multi-client diversity and security through redundancy. For a deeper dive into OCR’s design goals and report generation process, read the OCR protocol paper.

What is off-chain computation?

What is off-chain computation?

Off-chain computation refers to trust-minimized executions that are performed outside of a blockchain environment by Decentralized Oracle Networks (DONs). The Chainlink Network provides a wide range of off-chain computations that significantly enhance the capabilities of smart contracts and blockchain networks, including scalable code execution, oracle update transaction batching, random number generation, privacy-preserving contracts, fair transaction ordering, and more. The off-chain computations performed by DONs extend Chainlink’s functionality far beyond secure data delivery while meeting the decentralized computation guarantees that are fundamental to blockchain technology.

What are hybrid smart contracts?

What are hybrid smart contracts?

Hybrid smart contracts, also called hybrid contracts, are an evolution of smart contract design that was pioneered in the Chainlink 2.0 Whitepaper, in which contracts are securely composed of both on-chain and off-chain computing resources. Hybrid contracts are made possible by Chainlink Decentralized Oracle Networks (DONs), which provide a multiplicity of off-chain services to existing and future blockchain networks, enabling feature-rich, privacy-preserving, and scalable smart contract applications that are not practical or possible today.

What is Chainlink Verifiable Random Function (VRF)?

What is Chainlink Verifiable Random Function (VRF)?

Chainlink VRF brings secure random number generation to the blockchain. Chainlink VRF solves the difficult problem of providing an on-chain source of randomness that is publicly verifiable to be authentic and tamper-proof. Many smart contracts are augmenting the value they can create by utilizing Chainlink VRF, specifically applications such as gaming dApps that must prove to their users that their source of randomness is provably fair and resistant to manipulation from any external entity. Chainlink VRF enables and accelerates the development of smart contracts focused on blockchain gaming, security, layer-two protocols, and various other use cases.

What is Chainlink Proof of Reserve?

What is Chainlink Proof of Reserve?

Chainlink Proof of Reserve provides smart contracts with the data required to calculate the true collateralization of any on-chain asset backed by off-chain reserves such as stablecoins and cross-chain assets. Operated by a decentralized network of oracles, Chainlink Proof of Reserve enables the autonomous auditing of collateral used within DeFi in real-time, ensuring users’ funds are protected from unforeseen fractional reserve practices and other fraudulent activity from off-chain custodians. This provides both the growing DeFi ecosystem and the traditional financial system a way to increase transparency of operations with definitive on-chain proof of any asset’s true collateralization.

What is DECO?

What is DECO?

DECO is a novel privacy-preserving oracle protocol that allows users to prove facts about their web (TLS) sessions to oracles without unveiling any confidential information on-chain. Developed by researchers at Cornell University and acquired by Chainlink, this technology extends the data security capabilities of HTTPS and TLS, guaranteeing that data remains private and tamper-proof during its delivery from various private and premium data sources. It does so by employing advanced cryptography and zero-knowledge proofs from any server using HTTPS/TLS, without revealing that data to the outside world or even to the final computation using the data. DECO creates a new method of providing private and premium data across the internet while maintaining its confidentiality and security at previously unachievable levels.

This additional level of data security enables previously inaccessible data to be made accessible to both existing web systems and various blockchains and smart contracts through Chainlink oracles. Using DECO-enabled Chainlink nodes:

  • Premium data sources that have so far been unable to place high-quality data on public blockchains due to confidentiality concerns will be able to provide data to various blockchains and DeFi protocols. 
  • Enterprises will be able to prove the state of private data to other enterprises and blockchain records without revealing internal data on-chain.
  • Consumers will be able to prove personal data like identity or bank balances to smart contracts without giving applications full access to their personal accounts, maintaining their privacy.

Explore the blog post 77 Smart Contract Use Cases Enabled by Chainlink and the categories below for a deeper dive into applications of decentralized oracles:  

How does Chainlink secure DeFi?

How does Chainlink secure DeFi?

Decentralized finance (often referred to as DeFi) is a growing movement around recreating common financial instruments from traditional finance using decentralized infrastructure. Rather than needing centralized entities to facilitate the movement of financial markets, users can access, trade, and lend assets using open-source software running on decentralized networks. The result is self-running, peer-to-peer financial markets based on transparency, open access, and data-driven automation.

Chainlink oracle networks enable tamper-resistant and sustainable price feeds that are currently in use by several top DeFi applications to secure billions of dollars worth of locked value. By enabling smart contracts to access new forms of data as inputs, while retaining the underlying security and reliability guarantees of the smart contract, Chainlink plays a crucial role in the DeFi industry’s growth.

In the current price reference feed model, independent nodes in the Chainlink Network monitor for price changes off-chain, trigger an update when the price change hits a defined threshold (e.g. 1%), fetch aggregated market prices from high-quality data providers, and then aggregate node responses to generate a highly available and manipulation-resistant price update on-chain. Smart contracts can then access an extremely accurate price using a simple function call.

Some examples of price feed users include:

  • Synthetic asset platforms that require the price of real-world assets in order to mint their representation on-chain. These platforms use Chainlink reference contracts to create tokens tied to real-world assets, such as gold, indices, or even car loans.
  • Lending and borrowing platforms that require a price feed to ensure the total value of the collateral. These platforms use Chainlink to issue and settle loans, liquidate collateral, and calculate interest payments.
  • Stablecoins that require a price feed to assert the value of the underlying collateral backing the asset. These platforms use Chainlink to create stablecoins pegged to fiat currency, currency baskets, or commodities.
  • Asset management platforms that require a reliable price feed for the critical rebalancing of asset ratios. These platforms use Chainlink to power a decentralized exchange (DEX), adjust capital pools, or facilitate multiple forms of payment.
