Main conclusions
The official launch of the Binance Oracle took place in October 2022.
Blockchain oracles are services that receive, verify, and transmit off-chain data to smart contracts on the blockchain.
Binance Oracle introduces a more reliable, secure and accurate solution for smart contracts to receive data outside of their blockchain.
This article will tell you everything you need to know about the Binance Oracle, which allows smart contracts to access data outside of their native blockchain network.
Binance officially launched its own oracle in October 2022. Oracles—communication channels between distributed ledgers and the outside world—are playing an increasingly important role in the blockchain ecosystem. And now is the right time for Binance to introduce its reliable and secure service. Read on to learn more about the structure and features of the Binance Oracle.
What is a blockchain oracle?
Before learning about the Binance Oracle, you should understand what blockchain oracles are in general. Blockchain oracles are services that allow smart contracts to access data from sources that may be located outside of their native networks. In other words, they connect blockchains to the real world. These services help smart contracts access external data and execute based on off-chain inputs.
The data can be almost anything, from price information to weather forecasts. Oracles can also be bidirectional, meaning users can both receive data from the outside and send it in the opposite direction. Remember that an oracle is just a channel for transmitting data, and not the source of data itself.
Why Binance decided to launch an oracle
Binance sees enormous opportunity in the blockchain oracle space and believes that investing in this sector will allow the BNB Chain ecosystem and the broader digital asset space to thrive and evolve for the benefit of users. Oracles can serve as the foundation for Web3 and provide robust smart contracts that enable a wide range of use cases with the required real-world data.
Binance Oracle will support multiple blockchain partners within the BNB Chain ecosystem, marking another step in Binance's journey to become a leading infrastructure services provider for the digital asset industry.
What exactly is the Binance Oracle?
The purpose of the Binance Oracle is to help execute smart contracts that require off-chain data entry. Built specifically for the needs of DeFi applications, Binance Oracle will transmit data reliably and securely to the blockchain.
Binance Oracle Components
Initially, Binance Oracle will maintain index prices for the most popular digital assets. To do this, it will rely on a combination of 5 reliable components:
Receiving price data from numerous centralized exchanges and aggregating them using your own formula.
Use your own Threshold Signature Scheme (TSS) to sign individual data streams.
Feeding the latest index price to the oracle using a flexible time window and taking into account price deviation.
Simple and clear interfaces for DApps on the blockchain.
Constant monitoring and instant response 24/7.
High security
One of the strengths of Binance Oracle is its threshold signature scheme, which is applied to every data stream in the distributed signing process, ensuring there is no single point of failure in the data protection system. The authenticity of the data is also constantly verified using the Binance public key - this ensures that the data is not tampered with in transit.
High Availability
Another benefit of Binance Oracle is its high availability. First, several top exchanges are hand-selected and intelligent algorithms ensure the index price is accurate. This means you get real-time information from leading sources. At the same time, the architecture of Binance Oracle components ensures that the system can continuously provide data in any extreme scenario. A complete oracle infrastructure will be deployed in each region to provide region-wide protection against failures and unexpected events.
Oracle Binance has already included 10 BNB Chain projects in its early support program. These include Venus, Alpaca, SpaceID, Unilend, Deri, Ankr, Corite, Ultiverse and Beefy. The goal of the service is to serve as many Web3 teams and users as possible, providing flexible configuration options.
Conclusion
Blockchain oracles play an extremely important role in the blockchain ecosystem by providing a stream of external data. Binance Oracle, launched in October 2022, will bring security, reliability and efficiency to the BNB Chain infrastructure services sector. It will allow smart contracts to connect to trusted data sources, ensuring information is always accurate, reliable and up-to-date. In the future, the service may be provided for other blockchains.
