Abstract

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.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a blockchain-based smart contract implementation method and device. Background technique [0002] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed non-tamperable and unforgeable distributed ledger. [0003] The concept of smart contracts was first proposed by Nick Szabo in 1994, but before the emergence of blockchain technology, smart contracts were not widely used due to the lack of a trusted execution environment. With the popularization of blockchain, smart contract technology has developed rapidly. Since the blockchain has the characteristics of decentralization, non-tampering and high availability, writing smart contracts into the blockchain in a digital form can ensure that the entire process of storage, reading, and execution of smart contracts is transparent, ...
