Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
In the related art of the block chain, the management of the block chain is usually performed by a management user directly operating the block chain. For example, publishing intelligent contracts to blockchains is by an administrative user publishing the intelligent contracts directly into blockchains.
Due to the lack of control, such a management method is likely to cause the exception of the block chain. For example, an issued intelligent contract is wrong, the wrong business logic in the intelligent contract directly affects the business data in the block chain.
To this end, embodiments of the present specification aim to implement the normalization and the streamlining of blockchain management. Management operation of the block chain is managed through an independent block chain management system, and the authority of the management operation of the block chain can be obtained only when the vote passes, so that the effect of strong management and control on the management operation of the block chain can be achieved.
Referring to fig. 1, fig. 1 is a flowchart illustrating a management method for a blockchain according to an exemplary embodiment. The method is applied to a block chain management system and comprises the following steps:
step 110: receiving a proposal request submitted by a management user for performing management operation on a block chain;
step 120: responding to the proposal request, invoking voting logic contained in a management contract deployed on the blockchain, generating voting events corresponding to the management operations for users participating in voting, so that the users participating in voting respond to the voting events, perform voting processing on the management operations, and submit voting results to the management contract as event responses corresponding to the voting events for voting and summarize; acquiring a voting processing result of the users participating in voting, which is obtained by voting and summarizing the management contract, for the management operation, and determining whether the voting passes for the management operation based on the voting processing result; and if so, granting the management user the authority of management operation aiming at the block chain.
In this specification, the blockchain management system is a system that standardizes management of blockchains and intelligent contracts in blockchains. The blockchain management system is a system independent of blockchains, and the proposal and voting process for managing the blockchains is completed by calling a management contract.
In an embodiment, the method may further include:
receiving a management request for the block chain initiated by the management user; wherein the management request comprises a management operation to be executed by the management user for the block chain;
determining whether the management user has a right to perform the management operation for the blockchain in response to the management request; if so, performing the management operation on the blockchain.
In this specification, an independent blockchain management system is used to manage the management operation of the blockchain, and the blockchain management system only executes a management request initiated by a management user having a management operation authority, so as to achieve an effect of strongly controlling the management operation of the blockchain.
In one embodiment, the blockchain management system interfaces with a blockchain service platform;
in step 120, invoking a voting logic included in the management contract deployed on the blockchain, and generating a voting event corresponding to the management operation for a user participating in voting, includes:
generating a proposed transaction corresponding to the proposed request, and sending the proposed transaction to the blockchain service platform, and further sending the proposed transaction to a node device in the blockchain by the blockchain service platform, so that the node device invokes voting logic included in a management contract deployed on the blockchain in response to the proposed transaction to generate a voting event corresponding to the management operation for a user participating in voting;
in step 120, obtaining a voting processing result of the user participating in the voting for the management operation includes:
and obtaining a voting processing result of the user participating in voting aiming at the management operation, wherein the voting processing result is obtained by voting and summarizing the management contract pushed by the block chain service platform.
In this specification, the block chain Service platform may include a BaaS platform (also referred to as a BaaS cloud) for providing a block chain as a Service (BaaS). The BaaS platform can provide a pre-programmed software mode for activities (such as subscription and notification, user verification, database management and remote updating) occurring on the block chain, provides simple and easy-to-use one-key deployment, rapid verification and flexible and customizable block chain service for user client side computing equipment coupled with the BaaS platform, and further can accelerate the development, testing and online of block chain service application and assist landing of block chain business application scenes of various industries.
In this specification, the blockchain management system may complete the invocation of the management contract through the blockchain service platform, so as to complete the proposing and voting process for managing the blockchain.
The following description takes the upgrade of the intelligent contract in the blockchain as an example:
the function of a Smart contract (Smart contract) is generally provided in the block chain. An intelligent contract on a blockchain is a contract on a blockchain that can be triggered to execute by blockchain transactions. An intelligent contract may be defined in the form of code. By writing the execution logic of specific business into a target intelligent contract in a code form and issuing the contract into the blockchain, various complex business logics can be realized on the blockchain.
Since the execution logic of the business can change continuously with the development of the business, the target intelligent contract also has the requirement of upgrading. However, due to the non-tamper-able characteristic of the blockchain, the target smart contract which is already issued in the blockchain cannot be modified; therefore, the contract code is not simply modified for the target intelligent contract upgrading, but a completely new version (containing upgraded business logic) of the target intelligent contract needs to be issued, and then the target intelligent contract in effect in the block chain is switched to the target intelligent contract of the new version so as to lose the target intelligent contract of the old version before failure.
In practical application, because the target intelligent contract may have an incompatibility problem in the upgrading process, if the target intelligent contracts in the block chain are all switched to a new version, once the new version is incompatible with the old version, the execution of normal services is affected. Based on this, a gray scale upgrade for the target intelligent contract is generated. The method for upgrading the gray scale can ensure that a block chain for deploying the target intelligent contract is stable, problems can be found and timely processed in the initial gray scale stage, and the influence range of the problems is limited even if the user group in the initial gray scale stage is few.
Since the blockchain deploys the target intelligent contracts of the old version and the new version at the same time, whether the blockchain transaction initiated by the transaction initiator is a test transaction related to gray scale upgrading needs to be sensed, and the corresponding target intelligent contract is called to execute the blockchain transaction.
Specifically, in this specification, the blockchain deploys an old version of target intelligent contract before the grayscale upgrade and a new version of target intelligent contract after the grayscale upgrade; and the management intelligent contract is used for carrying out gray scale upgrading management on the target intelligent contract.
In one embodiment, the management operation includes a version-up related operation on a target intelligent contract deployed in the blockchain; the management contract comprises upgrade management logic related to version upgrade of the target intelligent contract; the block chain is provided with an old version target intelligent contract before version upgrading and a new version target intelligent contract after version upgrading; the management contract maintains a drainage policy for draining the target intelligent contract; the drainage policy comprises a first drainage policy for draining the contract invocation transaction aiming at the target intelligent contract to the target intelligent contract of the new version for execution and a second drainage policy for draining the contract invocation transaction aiming at the target intelligent contract to the target intelligent contract of the old version for execution;
in step 120, the performing the management operation on the blockchain includes:
and generating a management transaction corresponding to the management request, sending the management transaction to the blockchain service platform, and further sending the management transaction to node equipment in the blockchain by the blockchain service platform, so that the node equipment responds to the management transaction, calls an upgrade management logic contained in the management contract, and switches the drainage policy maintained by the management contract to a drainage policy corresponding to an operation related to version upgrade.
In one embodiment, the private key of the management user is stored in the blockchain management platform;

In one embodiment, the version upgrade comprises a grayscale upgrade; the grey scale upgrade comprises a pre-release stage of the target intelligent contract aiming at the new version; and a gray scale release stage after the pre-release stage is completed;
the operation related to the version upgrading comprises the following steps: the method comprises the following steps of carrying out a first operation of pre-release testing corresponding to a pre-release stage on a target intelligent contract, carrying out a second operation of gray level testing corresponding to a gray level release stage on the target intelligent contract, and carrying out a third operation of version switching on the target intelligent contract after the gray level testing is finished;
the invoking of the upgrade management logic included in the management contract switches the drainage policy maintained by the management contract to a drainage policy corresponding to an operation related to the version upgrade, including:
if the management operation is the first operation, calling an upgrade management logic corresponding to the version upgrade operation and contained in the management contract, and switching a drainage policy, which is maintained by the management contract and corresponds to a pre-release test transaction corresponding to the pre-release test, into the first drainage policy;

In this specification, the process of gray scale upgrading may be to perform pre-release first, and complete the pre-release test; and then carrying out gray release, completing the gray release test and carrying out the production stage.
Because the pre-release test transaction corresponding to the pre-release test needs to be executed by the target intelligent contract of the new version, the block chain management system needs to switch the drainage policy corresponding to the pre-release test transaction to the first drainage policy, that is, switch from the target intelligent contract of the old version to the target intelligent contract of the new version, so that the pre-release test transaction is executed by the target intelligent contract of the new version. Further, whether the new version of the service intelligent contract passes the pre-release test corresponding to the pre-release stage or not can be determined according to the execution result of the pre-release test transaction; if so, gray scale distribution may be performed. Otherwise, if not, the block chain management system needs to switch the drainage policy corresponding to the pre-release test transaction to a second drainage policy to implement rollback of the gray scale upgrade.
Similarly, since the gray release test transaction corresponding to the gray release test also needs to be executed by the target intelligent contract of the new version, the block chain management system needs to switch the drainage policy corresponding to the gray release test transaction to the first drainage policy, that is, switch from the target intelligent contract of the old version to the target intelligent contract of the new version, so that the target intelligent contract of the new version executes the gray release test transaction. Further, whether the new version of the service intelligent contract passes the gray release test corresponding to the gray release stage or not can be determined according to the execution result of the gray release test transaction; if so, a production phase may be performed. Otherwise, if not, the block chain management system needs to switch the drainage strategies corresponding to the pre-release test transaction and the gray release test transaction into the second drainage strategy so as to realize the rollback of the gray scale upgrade.
In the production stage, the blockchain management system needs to switch the drainage policy corresponding to the production transaction to the first drainage policy, so that the production transaction is executed by the target intelligent contract of the new version. If the execution result of the production transaction is wrong, the block chain management system needs to switch the drainage strategies corresponding to the pre-release test transaction, the gray release test transaction and the production transaction into a second drainage strategy so as to realize the rollback of the gray upgrading.
The gray scale upgrading of the intelligent contract can be completed by the transaction testing and the drainage strategy switching.
The following description takes the gray scale upgrade of node devices in the blockchain as an example:
and at least part of transaction processing logic supported by the node equipment in the block chain is replaced by the transaction processing logic of a new version after the gray scale is upgraded.
In one embodiment, the management operations include version-up related operations on transaction processing logic supported by node devices in the blockchain; a blockchain service platform interfaced with the blockchain management system maintains a drainage policy that drains the blockchain transactions; at least part of transaction processing logic supported by node equipment in the blockchain managed by the blockchain service platform is replaced by transaction processing logic of a new version after gray scale upgrading; the drainage strategy comprises a third drainage strategy for sending the blockchain transaction to the node equipment supporting the transaction processing logic of the new version for execution and a fourth drainage strategy for sending the blockchain transaction to the node equipment supporting the transaction processing logic of the old version for execution;
in step 120, the performing the management operation on the blockchain includes:
and sending the management request to the blockchain service platform, so that the blockchain service platform responds to the management request and switches the drainage strategy maintained by the blockchain service platform to a drainage strategy corresponding to the operation related to the version upgrading.
In one embodiment, the version upgrade comprises a grayscale upgrade; the grey scale upgrade comprises a pre-release stage of the target intelligent contract aiming at the new version; and a gray scale release stage after the pre-release stage is completed;
the operation related to the version upgrading comprises the following steps: performing a fourth operation of a pre-release test corresponding to the pre-release stage on the transaction processing logic supported by the node device in the block chain, performing a fifth operation of a gray scale test corresponding to the gray scale release stage on the transaction processing logic supported by the node device in the block chain, and performing a sixth operation of version switching on the transaction processing logic supported by the node device in the block chain after the gray scale test is completed;
the sending the management request to the blockchain service platform so that the blockchain service platform responds to the management request and switches the drainage policy maintained by the blockchain service platform to a drainage policy corresponding to an operation related to the version upgrade includes:
sending the management request to the blockchain service platform, so that the blockchain service platform responds to the management request, and when the management operation is the fourth operation, switching the maintained drainage policy corresponding to the pre-release test transaction corresponding to the pre-release test to the third drainage policy;
when the management operation is a fifth operation, switching the maintained drainage strategy corresponding to the gray scale test transaction corresponding to the gray scale test to the third drainage strategy;
and when the management operation is a sixth operation, switching the maintained drainage strategy corresponding to the production transaction to the third drainage strategy.
In this specification, the process of gray scale upgrading may be to perform pre-release first, and complete the pre-release test; and then carrying out gray release, completing the gray release test and carrying out the production stage.
Because the pre-release test transaction corresponding to the pre-release test needs to be executed by the node device supporting the transaction processing logic of the new version, the block chain service platform needs to switch the drainage policy corresponding to the pre-release test transaction to the third drainage policy, that is, switch from the node device supporting the transaction processing logic of the old version to the node device supporting the transaction processing logic of the new version, so that the node device supporting the transaction processing logic of the new version executes the pre-release test transaction. Further, whether the transaction processing logic of the new version passes the pre-release test corresponding to the pre-release stage or not can be determined according to the execution result of the pre-release test transaction; if so, gray scale distribution may be performed. Otherwise, if not, the block chain service platform needs to switch the drainage policy corresponding to the pre-release test transaction to a fourth drainage policy so as to implement rollback of the gray scale upgrade.
Similarly, since the gray release test transaction corresponding to the gray release test also needs to be executed by the node device supporting the new version of the transaction processing logic, the block chain service platform needs to switch the drainage policy corresponding to the gray release test transaction to the third drainage policy, that is, switch from the node device supporting the old version of the transaction processing logic to the node device supporting the new version of the transaction processing logic, so that the node device supporting the new version of the transaction processing logic executes the gray release test transaction. Further, whether the transaction processing logic of the new version passes the pre-release test corresponding to the pre-release stage or not can be determined according to the execution result of the gray release test transaction; if so, a production phase may be performed. Otherwise, if not, the block chain service platform needs to switch the drainage strategies corresponding to the pre-release test transaction and the gray release test transaction into a fourth drainage strategy so as to realize the rollback of the gray scale upgrade.
In the production stage, the blockchain service platform needs to switch the drainage policy corresponding to the production transaction to a third drainage policy, so that the production transaction is executed by the target intelligent contract of the new version. If the execution result of the production transaction is wrong, the block chain service platform needs to switch the drainage strategies corresponding to the pre-release test transaction, the gray release test transaction and the production transaction into a fourth drainage strategy so as to realize the rollback of the gray upgrading.
The gray scale upgrading of the transaction processing logic supported by the node equipment can be completed by the transaction testing and the diversion strategy switching.
