Villkorsstyrda betalningar på blockkedjor med smarta kontrakt och oraclelösningar

Sammanfattning: This report aims to investigates how smart contracts and oracles can be used to facilitate condition based transactions on blockchains. It contains both a theoretical study and practical implementations. Detailed are two approaches, one on the Ethereum blockchain and one on the Celo blockchain. Both approaches use centralised oracles but propose different methods for future decentraliziation. Blockchains as a payment platform are also investigated and promising indications are found.
