Estimating the term…
The method concerns goods or services based on a blockchain information decentralised storage technology. Blockchain infrastructures have been enriched with smart contracts. The emergence of these smart contracts opens up new applications for blockchains, particularly in the exchange of services. However, the lack of confidentiality of solutions based on the use of smart contracts is an obstacle to their development. In order to solve this problem, the method is based on the introduction of an oracle capable of processing encrypted offers without having access to the decrypted content of these offers. An oracle is a third-party service run by several nodes, interfacing the blockchain network with the world. An oracle can feed external information back to a smart contract, or perform calculations on behalf of the smart contract in order to reduce the latter's calculation costs. Oracles are trusted entities.
A service offer processing method implemented by a computer interfacing with at least one node belonging to a blockchain network configured to execute a smart contract of the blockchain, the method comprising:
A service provision method implemented by a node belonging to a blockchain network configured to execute a smart contract of the blockchain, the method comprising:
A computer interfacing with at least one node belonging to a blockchain network configured to execute a smart contract of the blockchain, the computer comprising at least one processor configured to:
