The sequence of steps involved in the embodiments is for illustrative purposes to illustrate the implementation of the present application, and the sequence of steps is not limited and can be adjusted as needed.

In a specific embodiment, as shown in fig. 1, a life cycle of an intelligent contract mainly includes deployment, upgrade, freezing, thawing, version rollback, version forwarding, and parameter upgrade of the intelligent contract, and a system back end thereof is logically divided into three modules including a proposal processing module, a message module, and a proposal execution module;

the proposal processing module comprises proposal initiation and voting; the message module comprises the generation and processing of messages; the proposal execution module executes the installation and instantiation operations of different intelligent contracts according to different types of proposals.

In this embodiment, as shown in fig. 2, the step of managing the intelligent contract specifically includes:

s1, acquiring an intelligent contract proposal request initiated by a proposal initiating organization in the channel;

s2, if the proposal initiating is successful, initiating a voting notification to make all organizations in the channel vote for the proposal request;

s3, if the vote exceeds half, generating a proposal to-be-executed message and sending the proposal to the BaaS terminal;

s4, executing proposal, and carrying out installation and instantiation operation of related intelligent contracts, wherein the related intelligent contracts run in an external chain code container;

s40, the BaaS end receives the proposed to-be-executed message; installing related intelligent contracts in endorsement nodes selected by a proposal initiating organization; configuring Stateful and Service for the external chain code container;

and S41, after the external chain code container is normally started, the current intelligent contract ID of the organization where the endorsement node is located points to the installed related intelligent contract ID, and the related intelligent contract is instantiated.

For all the passing operation intelligent contract proposals, the installation and instantiation operation of related intelligent contracts are required during the execution, the intelligent contracts are operated in an external chain code container, the influence of an isolated container on the overall scheduling under the k8s environment is reduced, the contract construction logic hard-coded by an endorsement node is not relied on, and the high availability of the chain code is ensured, and the method mainly comprises the following steps:

For the specific steps of managing an intelligent contract (hereinafter referred to as a contract), the main behaviors of the three modules in the embodiment include:

in a first aspect, for a proposal for operating an intelligent contract, the proposal processing module first verifies whether the state of the intelligent contract meets the corresponding state requirement, and needs to meet the following rules:

1) for the contract deployment, the contract to be deployed cannot be identical to other contracts in the block chain network, and once the intelligent contracts with the same name and the same version number are repeatedly installed on the same endorsement node, an installation error can be caused;

2) if the proposal is to deploy other contract operations outside the contract, the current contract cannot have the proposal in process, and the condition that one contract is operated by a plurality of proposals simultaneously can cause confusion occurs; for example, if the current state of the contract is frozen and an upgrade request and a unfreeze request are initiated at the same time, the state of the contract is uncertain after the proposal is executed, and therefore transactional guarantee must be provided for contract operation;

3) a deployment contract must be one that does not exist; upgrading a contract must be upgrading an existing contract; freezing a contract must be freezing an existing and running contract; the thawing contract must be a contract that is in freezing; version rollback must be that the contract already exists and is running and there is the last version, and version advance must be that the contract already exists and is running and there is the next version.

After the proposal is successfully initiated, informing relevant organizations to carry out voting operation on the proposal, and if more than half of the organizations agree with the contract operation proposal, generating a proposal to-be-executed message and sending the proposal to the BaaS terminal; if half of organizations refuse contract operation proposal, the proposal voting state is marked as that the table fails;

particularly, the permission for redeploying the intelligent contract is set for certain specific organizations in the channel, when the proposal initiation fails and is the deployment of the intelligent contract, if the proposal initiation organization has the permission for redeploying, a request for redeploying is initiated, and the deployment of the intelligent contract is carried out again.

In this embodiment, unlike other management contract proposals, the deployment contract is the deployment of a new contract, and before deployment, a new contract needs to be created, and the creation of a new contract is also performed in the form of initiating a proposal.

In the second aspect, the message module is divided into two parts, including contract end message generation and BaaS end message processing;

the type of the message comprises a proposal initiating result, a proposal voting result and a proposal executing result;

the BaaS terminal acquires all state information with Message and MspID as prefixes when calling a function for acquiring the Message, wherein the MspID is acquired based on information of a caller; if the proposal is initiated completely, newly adding an initiating result message in a database; if the proposal voting is finished, newly adding voting result information in a database; and if the proposal is executed, newly adding an execution result message in the database.

In a third aspect, the proposal execution module performs installation and instantiation operations of related contracts;

the proposal execution is a part of the BaaS for carrying out actual operation on the contract, and the BaaS end can carry out actual operation on the contract when receiving a new proposal to be executed message;

the processing according to the different proposal types is as follows:

1) the contract deployment is to deploy a new contract, upload the new contract to the channel, and install the new contract at an endorsement node where the new contract needs to be deployed, wherein the proposal information at least comprises the name and the version number of the new contract, the channel name, the initialization parameter, the endorsement policy and the private data, and the specific flow is shown in fig. 3;

2) the contract upgrading is to upgrade the current contract, select the existing contract in the channel and install, wherein, the proposal information at least includes the name and version number of the current contract, the name and version number of the upgraded contract, the channel name, the endorsement policy and the private data, and the specific flow is as shown in fig. 4;

3) all the calls of the current contract are modified to return 'the contract is frozen', the endorsement policy of the current contract is replaced by the endorsement policy of all the organizations, the ID of the contract is set to be null, the modified contract is the frozen contract, and the frozen contract is installed, wherein the proposal information at least comprises the name, the version number and the channel name of the current contract, and the specific flow is shown in FIG. 5;

4) the unfreezing contract is the original contract before freezing is installed, wherein the proposal information at least comprises the name, the version number and the channel name of the current contract, the current contract is selected, and the specific flow is shown in figure 6;

5) the version rollback and version advance of the contract require that the current contract is in operation, and the contract with the previous version/the next version is available, and the contract meeting the conditions is selected for installation, wherein the proposal information at least comprises the name of the current contract, the version number of the contract with the previous/next version, and the channel name, and the specific flow is shown in fig. 7 and 8;

6) upgrading parameters of the contract, modifying the endorsement policy and the private data set of the contract without changing the version number of the current contract, and installing the modified contract, wherein the proposal information at least comprises the name, the version number, the channel name, the endorsement policy and the private data of the current contract, and the specific flow is shown in fig. 9;

note that the upgrading, freezing, unfreezing, version rollback, version advance, parameter upgrading, when installing the relevant contract, the endorsement node where the current contract is installed is selected for installation.
