Chainlink is blockchain middleware that allows smart contracts to access key off-chain resources like data feeds, various web APIs, and traditional bank account payments. By providing smart contracts secure access to these key resources, ChainLink allows them to mimic real world agreements that require external proof of performance and need to make payment in widely available payment methods e.g. bank payments.

The Chainlink Network is a decentralized network of ChainLink Nodes, which are all selling usage of specific data feeds, APIs and various off-chain payment capabilities directly to a smart contract. Any data, payments, e-signature, or other API provider, as well as individual developers, can easily join the network by connecting an API they're familiar with. Once the API they'd like to offer to smart contracts is connected to a ChainLink, they become a ChainLink Node Operator, responsible for keeping that API connected to the ChainLink Network and being compensated in LINK for their successful fulfillment of on-chain requests.

Smart Contracts with Real Power. The Witnet protocol gives smart contracts real power by connecting them to any online ... Sport results, stock prices, weather forecasts or even other blockchains! Witnet is a decentralized oracle network that connects smart contracts to the outer world. It aims to allow any piece of software to retrieve the contents published at any web address with complete and verifiable proof of its integrity and without blindly trusting any third party.

Band Protocol is a cross-chain data oracle platform that aggregates and connects real-world data and APIs to smart contracts. It is a protocol to Create Token-Curated Registry, each with its own community token. We band communities with open and reliable data source.

Razor Network is a decentralized oracle providing data to the smart contracts using a network of stakers. Razor network is fast, robust and offers a high degree of economic security due to its full scale decentralization. The continually evolving platform is fully prepared to swiftly and smartly handle any unforeseen incidents.

It connects smart contracts with data in fast and secure way. Smart contracts do not have access to external data. Such data is necessary for operation of various decentralized applications.

Traditionally this is done by using a centralized servers called “Oracles”. But they are a single point of failure in otherwise decentralized applications and must be trustworthy.

Tensor is the Multi-chain NFT Pricing Protocol.

Price oracles provide pricing information for all things that have value attached to it. For example, there exists price oracles for deeply liquid instruments such as equity stocks, cryptocurrencies, and foreign currencies.

An NFT price oracle provides pricing information for NFTs (yes, really) and is a crucial pre-requisite for NFT financialization where capital efficient floor indices, lending, staking & more are possible. 

Creating a price oracle is hard. Creating a price oracle for an illiquid and non-fungible asset class is even harder. Tensor aims to provide a robust & responsive NFT price oracle-as-a-service for dapps, protocols, and organizations that need accurate and up-to-date pricing information on NFTs.

Algoracle is a decentralized oracle network that links the Algorand blockchain to the physical world. To obtain data, smart contracts building on Algorand can call the feed contract for values. Algoracle will also debut sports, cryptocurrencies, stock, and weather feeds over the coming months.

The Algorand Foundation says this about Algoracle, “Algoracle is Algorand’s premier oracle, built natively on Algorand for and by Algorand developers. We’re excited for what’s to come!”

Moreover, Algoracle employs a network of feed providers and node runners to deliver feeds to smart contracts to ensure decentralization. Currently, institutional-grade providers such as AmberData, Brave New Coin, CryptoCompare, and dxFeed are providing Cryptocurrency price data to power the testnet app. Regarding future goals, the focus will be on adding a variety of feeds such as Sports, Weather, NFT prices as well as off-chain computation capabilities before launching to mainnet.
