2024年1月12日 · Blockchain oracles are entities that connect blockchains to external systems, thereby enabling smart contracts to execute based upon inputs and outputs from the real world.

2021年8月3日 · 区块链外信息写入区块链内的机制，一般被称为预言机 (oracle mechanism) 。 预言机的功能就是将外界信息写入到区块链内，完成区块链与现实世界的数据互通。

A blockchain oracle is a third-party service for smart contracts. Oracles provide trusted information based on the outside-world sources to the on-blockchain smart contracts. An oracle typically encapsulates the real-world complexity outside of the blockchain.

2023年6月16日 · Blockchain oracles are entities that connect blockchains to external systems, allowing smart contracts to execute depending on real-world inputs and outputs. Oracles give the Web...

2024年3月4日 · A blockchain oracle is a bridge enabling smart contracts to access external data and systems, including other blockchains and real-world events. This connectivity facilitates the execution of smart contracts and their integration into the Web3 ecosystem.

2024年7月25日 · Oracles are applications that produce data feeds that make off-chain data sources available to the blockchain for smart contracts. This is necessary because Ethereum-based smart contracts cannot, by default, access information stored …

2023年11月28日 · What is a blockchain oracle? Blockchain oracles are third-party services that provide smart contracts with external information. They serve as bridges between blockchains and the outside world.

2023年9月21日 · Blockchain oracles are entities that connect blockchains to external data sources, allowing smart contracts to execute predetermined actions with accurate, real-world data. Oracles are needed because blockchains are closed systems and, therefore, cannot easily fetch data from the outside world.

2023年9月27日 · Blockchain oracle establishes a connection between a blockchain and the real world. Oracles send data to smart contracts running on the blockchain, which the smart contracts then utilize to execute predetermined actions in response to the data.

2023年1月31日 · A blockchain oracle is a data feed that sources, verifies, and transits off-chain data (data from other blockchains and the outside world) to smart contracts living on the blockchain. In addition to sourcing off-chain data and transmitting it to the blockchain, an oracle can relay data from it to external systems.
