Description
Technical Field
The invention belongs to the technical field of block chains, and particularly relates to a Fabric block chain configuration method and system based on an intelligent contract.
Background
The intelligent contract technology born from blockchains is a computer protocol that propagates, verifies, or executes contracts in an informational manner. The intelligent contract technology provides a publicly transparent contract computing protocol, and also includes the technical characteristics of block chain data security, distribution, traceability and non-falsification, and aims to provide security superior to the traditional contract method and reduce other transaction costs related to the contract. As one of the most popular and mature block chain frameworks in the industry at present, fabric has the advantages of good expansibility and physical isolation, and the like, and is suitable for constructing a union chain and providing an inter-enterprise trust data platform.
One of the prior art is: the method is characterized in that the block chain configuration and the intelligent contract management of the open source block chain platform Hyperlegder Fabric (IBM corporation) are all processed offline by using an official basic tool, and the file interaction between organizations needs to be carried out through offline channels such as mails, U disks, network disks and the like. However, this solution has the following disadvantages: 1) The default modification strategy of the Fabric blockchain configuration item is modified only by passing through a half, and the more the number of participating mechanisms is, the more digital signatures are collected, the higher the management cost is; 2) The Fabric blockchain configuration modification file must be signed by using a common node certificate, and the peripheral blockchain application is participated in the node by using the certificate used when the Fabric blockchain application is docked with the Fabric through an official sdk, so that the configuration modification operation cannot be carried out by using the sdk in a peripheral system; 3) The configuration updating is inconvenient, the configuration updating file needs to be generated on line by means of an official tool, the operation is complex and tedious, and the signed configuration file needs to be digitally signed on line between institutions, so that the risk of information leakage is increased; 4) The intelligent contract is difficult to deploy and upgrade, on one hand, the deployment and upgrade of the intelligent contract are completed by a command line tool on line, the operation is inconvenient, and on the other hand, the offline transfer of the intelligent contract installation file can increase the management cost and the information leakage risk; 5) The participating institutions can only view the intelligent contract information of the corresponding participating nodes of the institutions, and the information is invisible to other participating institutions in the chain and lacks of a unified intelligent contract monitoring view.
In addition, by adjusting the default configuration item modification strategy, a few organizations in the participating organizations are allowed to be designated as management organizations, the configuration update file is signed by the second half organization in the management organization group, namely, the configuration update file is legal, and the participating node certificate is used when the configuration update file is signed, so that the configuration modification can be directly carried out by utilizing sdk in a peripheral system. The configuration information and the intelligent contract files which need to be managed are processed and then directly linked up by utilizing the self characteristics of the block chain, meanwhile, the digital signatures of corresponding participating nodes are automatically acquired, the execution condition of the updating operation is fed back, and the transfer efficiency is greatly improved on the premise of ensuring the interaction reliability of the data files among the organizations. Based on the scheme, the cross-organization whole-flow-line processing of block configuration management and intelligent contract management is realized by means of the official sdk and the self-developed cross-organization flow engine, so that the management cost is reduced, and the processing efficiency is improved. However, the above solution has the following drawbacks: 1) When the self-research process engine, the information feedback API and the official sdk are called in a combined mode, due to the relative independence of all parts, consistent transaction control is lacked, and the problem that process related information is inconsistent with data on links such as actual block configuration information and the like can occur under extreme conditions; 2) And the intelligent contract file is limited in size by the block size, the maximum size cannot exceed 99m, and otherwise, the blocking problem can occur.
Due to the self-positioning and other reasons, the Fabric platform has the problem of inconvenient block chain management in actual use, such as inconvenient block configuration management, difficult intelligent contract upgrade and deployment, lack of unified monitoring and the like.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of a Fabric blockchain configuration method based on an intelligent contract according to an embodiment of the present invention. As shown in fig. 1, the method mainly comprises the following steps:
and S11, adjusting a configuration item modification strategy in the created block file and the channel creation envelope file to designate a management mechanism group of the Fabric block chain.
A founding block, a genetics block in english, is a first block file of a block chain, in which basic configuration information of the block chain platform is recorded. In the Fabric platform, the created block includes configuration information such as configuration item modification strategy, participation node, consensus node information, block generation time interval, and block file size.
The modification strategy, mod policy in English, is used for specifying a condition that must be met by modifying the Fabric platform configuration item, and only if the condition is met, a certain configuration item is allowed to be modified, and the condition is that a digital signature of a semi-consensus node is collected by default.
Several participating mechanisms in the Fabric blockchain can be designated as a blockchain management mechanism group, and the mechanisms in the group can be added or deleted through a blockchain configuration management flow.
S12, a configuration updating initiating mechanism receives relevant information of a mechanism to be processed, which is input into a peripheral system of a management mechanism group, generates a configuration updating file after comparing the information with configuration information of an existing Fabric block chain, and collects a corresponding digital signature; wherein the configuration update initiating mechanism is a member of a group of management authorities.
When the Fabric blockchain management mechanism inputs the relevant information of the mechanism to be processed, such as name, domain name, root certificate, transaction certificate and the like, into the peripheral system, the flow is submitted, the configuration updating initiating mechanism compares the relevant information with the existing blockchain configuration information after receiving the relevant information, a configuration updating file is generated after comparison, and digital signatures are collected at the same time, and when the digital signatures of more than half of nodes in the management mechanism group are collected, the next step can be carried out.
And S13, the configuration updating initiating mechanism calls an intelligent contract through a peripheral system to uplink the configuration updating file and the corresponding digital signature, and simultaneously initiates a cross-mechanism block chain configuration management process of all mechanisms in the management mechanism group.
Step S14, configuring the update initiating mechanism to read the digital signatures of the chains of other management mechanisms in the management mechanism group.
After the step S13 is used to initiate the configuration management process of the inter-organization block chain, the peripheral system automatically collects and chains the corresponding digital signature of the organization when the other participating organizations pass the configuration management process through the approval of the peripheral system, and the configuration update initiating organization reads the digital signature of the chain.
When the majority of the management mechanisms in the management mechanism group agree to the configuration modification, the block chain peripheral system of any management mechanism can execute the configuration updating operation, and the processing efficiency is improved on the premise of ensuring the safety.
And S15, the configuration updating initiating mechanism calls a block chain configuration updating API through the peripheral system according to the configuration updating file, the collected digital signature and the read digital signature to execute configuration updating operation.
After the other management mechanisms complete the approval, the process flows to the configuration updating initiating mechanism, when the initiating mechanism passes the approval, the peripheral system calls the block chain configuration updating API according to the configuration updating file and the collected digital signature, the configuration updating operation is directly executed, and the configuration updating is completed.
In an embodiment, a customized Fabric configuration item modification policy and a customized Fabric configuration tool (for example, a configuration tool may be self-developed for each organization) may be used to modify an initial configuration file, and a management mechanism group with a relatively fixed number of members is specified, so that problems of too long configuration management process, difficulty in data signature collection, unsafe configuration file flow, necessity of executing configuration update operation under a common node line and the like under the condition that alliance participating organizations are numerous can be avoided, efficient, safe and convenient Fabric block chain configuration and intelligent contract management are provided, and management cost of a Fabric platform is effectively reduced.
In one embodiment, to ensure consistency, all participating mechanisms on a Fabric blockchain execute the same intelligent contract.
In one embodiment, the smart contracts are upgradeable. When the intelligent contract needs to be upgraded, the intelligent contract can be upgraded according to the steps shown in fig. 2:
and S21, calling the current intelligent contract by the intelligent contract upgrading initiating mechanism to package and chain up the new version intelligent contract files, and simultaneously initiating a cross-mechanism intelligent contract management process of which the participant is all participating mechanisms in the Fabric block chain.
The intelligent contract upgrading initiating mechanism can be an intelligent contract developing mechanism and is a participating mechanism of the Fabric block chain. Before this step, since the new intelligent contract is not updated, the original intelligent contract needs to be called for uplink during uplink.
And S22, all participating mechanisms in the Fabric block chain examine and approve the new version intelligent contract file and the intelligent contract management process.
And the participating mechanism examines and approves whether the codes in the new version of the intelligent contract file are legal or not and examines and approves whether the intelligent contract management process is legal or not, and when the examination and approval results of the two are both yes, the examination and approval is passed.
And S23, when each participating mechanism passes the approval, downloading a new version of intelligent contract file by the participating mechanism through the peripheral system and installing the new version of intelligent contract file on the participating mechanism node.
And S24, after all participating mechanisms in the Fabric Block chain pass the examination and approval, calling an intelligent contract upgrading API by the intelligent contract upgrading initiating mechanism through a peripheral system to execute upgrading operation so as to finish unified upgrading.
In one embodiment, when the intelligent contract upgrade initiating mechanism packages and chains a new version of intelligent contract file, the new version of intelligent contract file needs to be converted into a string file in a base64 form; when the intelligent contract upgrade initiating mechanism downloads a new version of intelligent contract file through a peripheral system and installs the new version of intelligent contract file on a corresponding participating mechanism, the string file in the base64 form needs to be converted into a compressed file for installation.
In one embodiment, in the process of upgrading the intelligent contract, the upgrading conditions of all participating mechanisms of the intelligent contract in the Fabric block chain are monitored, wherein the upgrading conditions comprise whether the participating mechanisms are installed successfully, whether the upgrading is successful after the installation, and the like.
Generally, when an intelligent contract is upgraded at a code level, a storage function of an intelligent contract code can be built in an initial intelligent contract, that is, a new version intelligent contract file in a compressed file form is converted into a new version intelligent contract character string uplink in a base64 form; the reading function of the intelligent contract code, that is, the new version intelligent contract character string in the form of base64 is converted into a new version intelligent contract file in a compressed file format, can also be built in the initial intelligent contract for convenient installation. In addition, a collection function can be built in the initial intelligent contract to collect the intelligent contract about the installation condition of each block link point. After upgrading is completed, the intelligent contract upgrading conditions of all the participating nodes on the monitoring chain can be tracked in the unified intelligent contract monitoring view, and the history and current version information of the intelligent contract upgrading conditions are checked.
The embodiment of the invention uses the intelligent contract to realize updating of the block chain configuration file and cross-organization safe circulation of the intelligent contract file, can automatically collect the data signature, automatically take effect to configure and modify according to the cross-organization flow state, execute the intelligent contract upgrading and updating, and can track the configuration modification history of the monitoring block chain and the intelligent contract upgrading history of all the participating nodes by using the unified monitoring view, thereby solving the trust problem of block chain management information among organizations, improving the cross-organization circulation efficiency of block chain management and improving the information safety.

In another embodiment, the present invention further provides a Fabric blockchain configuration system based on smart contracts, the structure of which is shown in fig. 3, and the system mainly includes: a preprocessing device 10 and a configuration update initiating mechanism 20.
The preprocessing device 10 is configured to adjust a configuration item modification policy in the creature block file and the channel creation envelope file to specify a management mechanism group of the Fabric block chain.
