Blockchain oracle (original) (raw)
A blockchain oracle is a third-party service that connects smart contracts with the outside world, primarily to feed information in from the world, but also the reverse. Information from the world encapsulates multiple sources, so that decentralised knowledge is obtained. Information to the world includes making payments and notifying parties. The oracle is the layer that queries, verifies, and authenticates external data sources, usually via trusted APIs, proprietary corporate data feeds and internet of things feeds and then relays that information.

| dbo:abstract | A blockchain oracle is a third-party service that connects smart contracts with the outside world, primarily to feed information in from the world, but also the reverse. Information from the world encapsulates multiple sources, so that decentralised knowledge is obtained. Information to the world includes making payments and notifying parties. The oracle is the layer that queries, verifies, and authenticates external data sources, usually via trusted APIs, proprietary corporate data feeds and internet of things feeds and then relays that information. (en) Un oracle de blockchain est une entité de confiance faisant partie d'un réseau informatique, transportant des informations du monde physique à un contrat intelligent. Il crée le lien entre le monde physique et une blockchain que des contrats intelligents parcourent, et permet à ces contrats de ne pas être limités aux informations internes à la blockchain. Cette technologie est utilisée actuellement par des applications décentralisées (DApps) utilisant des contrats intelligents nécessitant l'accès à des informations extérieures. (fr) |
