The role of oracle in decentralized financing (Defi): Open new possibilities
The rapid growth of cryptocurrencies has led to the development of a new class of financial institutions: Distributed Financing (Defi). Defi platforms work in blockchain networks so that users can borrow, borrow and exchange cryptocurrencies without the need for brokers and banks. One of the decisive components of these platforms is the Oracle network, which enables seamless interaction between blockchain data and external sources of information.
What are the Oracs?
Oracles are reliable nodes that collect and send real information to a blockchain -based system. These nodes act as mediators by granting users access to relevant data from different domains such as market information, news and other external sources. By integrating oracles, Defi platforms can use this information to communicate your decision-making processes, optimize trade strategies and create new financial instruments.
The role of oracle in decentralized financing
Oraacles play an important role in Defi by activating the following key functions:
- Distributed prices can be found : By combining prices from several oracles, Defi platforms can create real-time price feeds that reflect the market feelings and trends.
2
- Risk management : By analyzing external information about oracle, Defi platforms can identify potential risks and make more conscious investment decisions.
- Institutional investments : Oracle can help institutional investors with access to alternative funds such as cryptocurrency and provide transparent and reliable source of information.
Oraaklit
The Defi mode has several oracles, including:
- Intelligent contract base oraaklit : This Oraclos use intelligent contract programs to collect and send information to the block chain.
- API-controlled Oracas : These Oracles offer users an application interface (application programming interface) for users in order to obtain external real-time sources.
- Web3-based Oraaklit : These Oracls use web3 techniques such as EIP-1559 from Ethereum, interact with external nodes and collect information.
Examples of Defi platforms with Oraakkel
Several Defi platforms have already integrated oracle into their systems, including:
- Uniswap : This decentralized stock exchange (Dex) uses the intelligent contract-based oracles from OpenSea protocol to provide real-time price feed for your business.
- AAVE : A quotation form that uses applications from various external sources for guided oracles for collecting and sending market prices, interest and other relevant information.
- Sushiswap : This Defi Dex also relies on intelligent contract-based oracles from OpenSea Protocol to provide real-time price feed in your shops.
Challenges and opportunities
Although Orakaks have the potential to revolutionize Defi, there must be several challenges, including:
- Security risks : The integration of external nodes into blockchain networks can be a security risk if they are not properly secured.
- Data quality : The guarantee of accuracy and reliability of the information obtained from Oracles is of crucial importance for reliable decisions -Im.
On the other hand, there are many advantages of oracle-based defi platforms:
- Improved accuracy
: Oraaklit can provide real time data by reducing the risk of market volatility and improving the overall performance of trade.
- Increased transparency
: By offering users the opportunity to access external information directly into their blockchain money exchanges, oraaks promote openness in Defi systems.
