Problems solved by technology

In the alliance chain system, such a design has the following problems: there is a single point of failure problem, if the deployer loses its private key, this contract can no longer be upgraded; there is a problem of evil, a smart contract may have multiple participants, But in this design, the deployer can unilaterally upgrade the contract without the consent of the rest of the participants

Abstract

The invention discloses an intelligent contract upgrading method with controllable authority based on an intelligent contract. The method firstly deploys a contract upgrading intelligent contract, andthen deploys an intelligent contract to be upgraded including contract participant information and minimum agreed quantity information required to pass the contract related proposal. And then any block chain node receives the intelligent contract address to be upgraded proposed by the user to the contract upgrading intelligent contract, After the contract upgrading intelligent contract is judgedto be passed, the proposed event is generated and forwarded to all the user clients participating in the contract, and the client receives the user's vote and feeds it back to the contract upgrading intelligent contract after receiving the proposal. If the number of consents exceeds the preset number, the proposal is passed and applied, replacing the binary contract and completing the contract upgrade. The invention solves the centralization problem of the traditional contract upgrading mode, solves the problem of a single point of failure, and improves the safety of the contract upgrading.

Description

technical field [0001] The present invention relates to smart contract technology, in particular to a smart contract upgrade method with controllable authority based on smart contracts. Background technique [0002] Smart contracts are an idea proposed by Nick Szabo in the 1990s, almost at the same age as the Internet. Due to the lack of a trusted execution environment, smart contracts have not been applied to the actual industry. Since the birth of Bitcoin, people have realized that the underlying technology of Bitcoin, the blockchain, can inherently provide a trusted execution environment for smart contracts. Smart contracts are assembly language programmed on the blockchain. Usually people don't write the bytecode themselves, but compile it from a higher level language. [0003] The traditional blockchain smart contract upgrade uses the deployer to initiate an upgrade request, and the contract can be directly upgraded. In the alliance chain system, such a design has th...
