Description
Technical Field
The invention relates to the technical field of heterogeneous block chains, in particular to a data migration method of an intelligent contract between heterogeneous block chains.
Background
Blockchains are a completely new distributed infrastructure and computing paradigm for verifying and storing data using blockchain data structures, generating and updating data using distributed node consensus algorithms, securing data transmission and access control using cryptographic techniques, programming and manipulating data using intelligent contracts composed of automated script codes. Currently, blockchains are referred to by many large organizations as a significant breakthrough technique for drastically changing the business and even the operational modes of the organizations. In the fields of finance, internet of things, public welfare charity, medical health, supply chain and the like, more and more enterprise institutions begin to explore the application prospect of a block chain in the industry and plan a data circulation route map based on the block chain technology; in the face of opportunities and challenges brought by a block chain technology, all industries around the world are actively distributed, and an attempt is made to change the original business and management mode through the combined innovation technology to construct a novel ecosystem with multi-party participation and safe trust.
Smart contracts (english: Smart contracts) are a computer protocol intended to propagate, verify or execute contracts in an informative way. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible. The intelligent contract concept was first introduced by Nick Szabo in 1995. The goal of smart contracts is to provide a secure method over traditional contracts and to reduce other transaction costs associated with the contracts. An "intelligent contract" is a set of numerically defined commitments (commitments) that include an agreement on which the contract participants can execute the commitments. "
When the applicant applies for the present invention, through search, it is found that a chinese patent discloses a "data migration method for a blockchain multi-level intelligent contract," whose application number is "CN 201710230002.3," which discloses a data migration method for a blockchain multi-level intelligent contract. The method comprises the following steps: 1) constructing a contract tree model for a contract system with a plurality of contracts mutually invoked; 2) migrating data of the top-level contract except the contract address of the child node; 3) judging whether the node where the current contract is located is a leaf node; 4) deploying a new contract of the leaf node, migrating the data of the contract, and storing the contract address of the leaf node; 5) after the data migration of all the sub-node contracts is finished, deploying new contract migration contract data and storing new addresses of all the sub-node contracts; 6) repeating the steps 3) to 5), and migrating the contract address parameters of all the sub-contracts of the top-level contract. The invention solves the problem that the contract address as a parameter cannot be updated when complex intelligent contract data on the block chain is migrated, and realizes the data migration facing the block chain multi-level intelligent contract, but the data is invalid in the data migration process.
The existing data migration stability price of the block chain is poor, and the problem that the ID is invalid frequently occurs in the heterogeneous block migration process, so that a data migration method of an intelligent contract between heterogeneous block chains is provided.
