Oracles Integration in Blockchain-Based Platform for Smart Crop Production Data Exchange

Blockchain oracles are an intermediary designed to connect external non-deterministic information and real-world data the blockchain digital infrastructure. The variety of proposed solutions purposes great suggest that it is necessary take into account different features process specifically define required functionalities. purpose this paper present integration EOSIO blockchain-based platform for smart crop production exchange by contracts. functions two presented. Their described at design level implementation illustrated workflow diagrams internal processes between oracle applications contract in oracles’ application configuration files elements C++ contracts, such as constant variable declarations, multi-index tables, functions, actions called other contracts programs. As results operation, a report on detected emergency failures estimate cost ram resource
