Blockchain system for delaying execution of smart contract

摘要

The present invention relates to a blockchain system that delays execution of a smart contract. According to the present invention, a plurality of nodes that receive a process by a user to generate a specific transaction, and receive a block broadcasted by a block generating node that generates a block at each current time among the plurality of nodes to verify and participate It includes a blockchain network that is distributed to nodes that are being executed, and the node additionally generates a reservation transaction or a reservation smart contract to be executed at a reservation point set by the user and transmits it to the block creation node. As described above, according to the present invention, the blockchain system stores a reservation transaction or reservation smart contract requiring delay processing in a block that is generated at the present time, and processes the stored reservation transaction or reservation smart contract at the time when the transaction is confirmed. In addition, it has the effect of enabling the implementation of smart contracts or transactions that require delay processing.
