Description
Technical Field
The invention belongs to the field of block chain contract model and intelligent contract template design, and particularly relates to an intelligent contract template design method based on a block chain contract model.
Background
With the rise and the continuous development of the internet, a block chain is generated. A blockchain is a data structure that groups blocks together in a chain, cryptographically ensuring that the data is not tampered and counterfeitable. Intelligent contracts were proposed in 1996 by Nick Szabo, and block-chain technology not only supports programmable contracts, but also provides decentralized, non-tamper-able, and stable features that are well-suited to intelligent contracts. Each block is connected with the previous block in a hash mode, so that traceability is realized; meanwhile, the intelligent contract ensures that a distributed peer-to-peer network is constructed by using a distributed collective operation method under the condition that no central control node exists. The generation of each block is the consensus established by the participants on the sequence and the current state of the events of the transaction records of the whole system, and the malicious tampering and interference encountered in normal execution can be prevented through an intelligent contract.
Smart contracts currently on the market present some security risks. First, current blockchain intelligent contracts do not have uniform standards and specifications. Each participant can participate in the design of intelligent contracts, which are also very different for use in different blockchains. Second, current intelligent contracts lack the development of specialized blockchain architectures. The intelligent contracts are born in the digital currency transaction process, but the characteristics of the blockchain are not completely considered, so that some bugs are inevitably possessed. Third, existing intelligent contracts lack a rigid compliance check. An attacker may have a backup of the data of the whole block chain by cracking the intelligent contract codes and recording and storing the data, so that the block chain is attacked through the contract bugs. Finally, some contract failures and service failures occur in the intelligent contracts. Because the intelligent contracts are not provided with an effective means for guaranteeing the safety and the integrity before being issued, privacy disclosure, transaction overflow and abnormity and safety risks are easily caused, and the perfection and issuing of the intelligent contracts are seriously influenced.
Therefore, it is important how to create a standardized set of design templates and platforms for blockchain intelligent contracts. However, it is very difficult to establish a standardized set of intelligent contract templates and paradigms.
