Abstract: Registration and execution methods and apparatuses of a timed smart contract in a blockchain. The method includes: a registration request of a timed smart contract is received (S101); according to the registration request, the timed smart contract is registered to an oracle machine contract pre-deployed on the blockchain (S102); and an interface for connecting the timed smart contract to the oracle machine contract is generated for the timed smart contract, so that the oracle machine contract triggers execution of the timed smart contract by means of the interface in a timing manner (S103). The method achieves the management and execution of the timed smart contract by means of the blockchain.

Abstract: The present disclosure relates to the technical field of computers. Provided are methods and apparatuses for registering and executing a smart contract in a blockchain. An example implementation mode of the method includes: a first smart contract deployed on a blockchain is determined, wherein the first smart contract includes an event trigger function; identification information of the first smart contract and an event corresponding to the event trigger function are registered to a bottom layer of the blockchain by means of a preset bottom layer interface; and a corresponding monitoring interface is generated for the event, and event information related to the event is obtained by means of the monitoring interface, so as to execute the first smart contract based on the event information related to the event.

Abstract: Disclosed are a registration method, an execution method, an execution apparatus and an execution system of a timed smart contract in a blockchain, and relates to the technical field of computers. The method includes: a registration request of the timed smart contract is received; according to the registration request, an interface for the timed smart contract connecting to an oracle contract is generated for the timed smart contract, where the oracle contract is deployed on the blockchain and configured to receive time information sent by a trusted oracle, so as to supply the time information to the timed smart contract through the interface. The management and execution of the timed smart contract are realized via the blockchain.

Abstract: Provided are a transaction method and apparatus with a fixed execution order, and relates to the technical field of computers. According to one alternative implementation, the method includes: transactions to be executed are received, generating an assembled transaction is generated with the transactions having a same identifier based on an assembly rule, and the assembled transaction to a transaction pool is sent; parsing, in response to acquiring a transaction from the transaction pool, the assembled transaction which is acquired to obtain a transaction list; and transaction execution is performed based on an execution order of each transaction in the transaction list.
