Technical Field
The invention relates to the technical field of heterogeneous blockchains, in particular to a data migration method of intelligent contracts among heterogeneous blockchains.
Background
Blockchains are a completely new distributed infrastructure and computing paradigm that use block-chained data structures to validate and store data, distributed node consensus algorithms to generate and update data, cryptography to secure data transfer and access control, and intelligent contracts composed of automated script code to program and manipulate data. Currently, blockchains are referred to by many large organizations as a significant breakthrough technique that thoroughly changes traffic and even the organization's mode of operation. In the fields of finance, the Internet of things, public welfare, medical health, supply chains and the like, more and more enterprises begin to explore the application prospect of blockchains in the industry and plan data flow route patterns based on blockchain technology; in face of opportunities and challenges brought by the blockchain technology, all industries around the world are actively laid out, and an attempt is made to change the original business and management modes through the combined innovation technology, so that a novel ecological system with multiparty participation and safe trust is constructed.
Smart contract (english) is a computer protocol that aims to propagate, verify or execute contracts in an informative manner. Smart contracts allow trusted transactions to be made without third parties, which transactions are traceable and irreversible. The smart contract concept was first proposed by Nick Szabo in 1995. The purpose of smart contracts is to provide a security approach that is superior to traditional contracts and to reduce other transaction costs associated with the contracts. "an intelligent contract is a set of digitally defined commitments (commitments) that include agreements on which contract participants can execute the commitments. "
When the applicant applies for the invention, the Chinese patent discloses a data migration method of a block-chain-oriented multi-level intelligent contract through searching, the application number of the Chinese patent is CN201710230002.3, and the Chinese patent discloses a data migration method of a block-chain-oriented multi-level intelligent contract. The method comprises the following steps: 1) Constructing a contract tree model for a contract system with a plurality of contract calls; 2) Migrating data of the top-level contract except child node contract addresses; 3) Judging whether the node where the current contract is located is a leaf node or not; 4) Deploying a new contract of the leaf node, migrating data of the contract, and storing contract addresses of the leaf node; 5) After the data migration of all the child node contracts is completed, deploying new contract migration contract data and storing new addresses of all the child node contracts; 6) Repeating steps 3) through 5) to migrate the contract address parameters of all sub-contracts of the top-level contract. The invention solves the problem that the contract address can not be updated as a parameter when complex intelligent contract data on the block chain is migrated, and realizes the data migration of multi-level intelligent contracts facing the block chain, but the problems of invalid data and the like occur in the data migration process.
The existing blockchain data migration has poor stability and the problem that the ID is invalid frequently occurs in the heterogeneous blockchain data migration process, so that a data migration method of intelligent contracts among heterogeneous blockchains is provided.
