Method and apparatus for realizing intelligent contract based on block chain

The invention discloses an intelligent contract realization method and a device based on a block chain, relating to the computer field, which can carry out transaction confirmation in the realizationprocess of the intelligent contract so as to achieve state consistency. The intelligent contract implementation method comprises the following steps: determining a type of the transaction based on theidentification of the transaction driving the intelligent contract, wherein the type of the transaction comprises a first type of time-length transaction, wherein the first type of time-length transaction is a transaction whose execution time is longer than a preset value; when the transaction is the first type of long-term transaction, the transaction status management is carried out to realizethe decoupling of the intelligent contract running cycle and the consensus cycle. The present application is for smart contract implementation based on block chains. 本申请公开了种基于区块链的智能合约实现方法和装置，涉及计算机领域，能够在智能合约的实现过程中进行交易确认，从而达到状态致性
