An oracle is the thing that allows you to get that data into your smart contract. It either brings it on-chain for you to read from or pushes the data into your smart contract. Typically this is a...

DeFi oracles are layers verifying and then relaying critical on-chain data to the smart contract. How DeFi Oracles Work Blockchains have no on-chain data saved in their ecosystems. This makes DeFi oracles essential as they can perform queries through crypto exchange application programming interfaces and source the real-time data.

"DeFi is short for "decentralized finance," an umbrella term for a variety of financial applications in cryptocurrency or blockchain geared toward disrupting financial intermediaries." - Alyssa Hertig. The primary objective of DeFi is to eliminate the middleman like a third party or a government body while the transactions are being executed.

In terms of oracle usage, DeFi is basically using two oracle structures that are at best only relatively decentralized. There are other both new and old projects out there using oracles that are not mentioned (like Augur, Gnosis, Band or DIA) — but in terms of DeFi projects with some volume, the list above is comprehensive.

Oracles have become an indispensable part of the Decentralized Finance (DeFi) ecosystem. Over the past year, the capitalization of oracle projects has grown to tens of billions of dollars, which indicates their relevance to the industry. They are designed as APIs for the world outside of the blockchain.

Oracles are complex computerized systems that connect data from the outside world (off-chain) with the blockchain world (on-chain). Most blockchains have native cryptocurrencies that are used to transfer value, enable the operations of the protocol, or facilitate governance.

An oracle is the only source of the input data sent to a smart contract and the information it receives triggers certain actions, regardless of whether it is rebalancing a stablecoin or liquidating a loan. Thus, an oracle controls how a smart contract is executed.

Oracles are mechanisms in blockchains that can allow blockchains, which are otherwise closed-loop systems, to communicate with the outside world and to securely bring in data from the outside world into blockchains.

Current DeFi oracles manifest sluggish data choke points which could result in catastrophic and contagious liquidations, especially due to the composability of certain assets. DeFi's composability increases its usefulness, though that same characteristic poses threats if oracles malfunction. Table of Contents Centralization & Reputation Systems

Looking into the current DeFi landscape and identifying the oracles utilized within the sector, we could generally segregate oracles into five distinct categories. DeFi oracles are either centralized, decentralized, distributed, prediction markets, or delegated proof-of-stake (DPoS). Let's look at each of them: Centralized Oracles

What is an Oracle? Oracles are the middlemen that bridge the gap between real-world (off-chain) services and blockchain (on-chain) protocols. Oracles retrieve off-chain data and post this data to the blockchain for smart contract consumption. They also relay messages and instructions from a smart contract to off-chain external systems.

What is an oracle? An oracle acts as a trusted, off-chain, real-time source of data that a smart contract requires to execute an action on the blockchain. The API supplies this real-time data. It can be provided by companies like Coinbase and Binance . Blockchains are built to be entirely deterministic.

Oracles, collectively, are a mechanism to broadcast data from outside of the blockchain onto the blockchain. The Maker Protocol uses Oracles to obtain the real-time price of assets. This price is used to determine whether a CDP has enough collateral locked up.

The INSTAR DeFi Oracle is the latest use case demonstrating our work together.

Flare Finance brings with it an entire suite of DeFi products from Liquidity Pools, to Yield Farming, to Loans and Mutual Funds. We will cover some beginner concepts and offerings of Flare Finance.

For DeFi applications, an oracle is the source of information that triggers a smart contract to do certain actions. Therefore, an oracle controls how a smart contract is executed. If an oracle goes down, produces incorrect values, is manipulated, or has a vulnerability, the whole system could be compromised. ...

The most popular defi projects in this space are Nexus Mutual and Opyn. Oracles. Another really important although not strictly limited to finance part of the defi ecosystem are oracle services that focus on delivering reliable data feeds from the outside world into the smart contracts. The most popular project in this space is Chainlink.
