ETHUSD Price Oracle

Ethereum-Dollar price oracle that calls upon Binance’s public API.

What is an oracle?

Blockchain oracles are third-party services that provide smart contracts with external information. They serve as bridges between blockchains and the outside world. Blockchains and smart contracts cannot access off-chain data (data that is outside of the network). However, for many contractual agreements, it is vital to have relevant information from the outside world to execute the agreement.

Oracles provide a link between off-chain and on-chain data and are vital within the blockchain ecosystem because they broaden the scope in which smart contracts can operate. Without blockchain oracles, smart contracts would have very limited use as they would only have access to data from within their networks.

区块链blockchain预言器是第三方服务,它为智能合约提供外部信息。它们是区块链blockchain与外部世界之间的桥梁。区块链blockchain和智能合约无法访问链外数据(网络外的数据)。然而,对于许多合同协议而言,从外部世界获得相关信息以执行协议至关重要

开发目标

oracle提供了链外和链上数据之间的链接,在区块链blockchain生态系统中至关重要,因为它们拓宽了智能合约的运作范围。如果没有区块链blockchain预言机,智能合约的用途将非常有限,因为它们只能访问其网络内的数据
