Detailed Description
In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present disclosure, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in one or more embodiments of the present disclosure.

For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present description.

It is generally recognized that blockchain technology is a distributed infrastructure and computing paradigm that utilizes blockchain data structures to authenticate and store data, distributed node consensus algorithms to generate and update data, cryptography to secure data transmission and access, and intelligent contracts composed of automated script code to program and manipulate data.
Generally, a blockchain network is a distributed system, and its actual working capability usually depends on performance indexes of operations, storage, and the like of blockchain nodes; since the credibility of data on the chain is different from the traditional credibility of local data, the data processing (contract) and the result thereof on the chain must be commonly known in order to continue the credibility of the data in the processing process, and therefore, the block link point is usually designed as an integrated node tightly bound with the storage and computation.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a block link point structure and interaction in the related art; in this example, there may be a message bus in the blockchain node, through which the user interface, authentication, consensus, chain storage, executor, network, etc. functional modules in the blockchain node may perform data interaction, where the user interface may be used for interfacing with a user operating the node, and the network module may be used for data communication with other nodes (node 2, node 3, node 4) in the blockchain network.
Under the above typical structure, due to the variability of the demand of the block chain service for the computing resources and the storage resources, one of the computing resources and the storage resources of the block chain link points often reaches the bottleneck first, so that the other one is not fully utilized, and the resource waste occurs. For example, suppose that a large number of calculation steps exist in a certain intelligent contract, which may cause a large amount of consumption of calculation resources of a blockchain node, and after a calculation bottleneck is reached, the node cannot take over services of other intelligent contracts, and at this time, even if the storage resources of the blockchain node are still surplus, the storage resources cannot be utilized; for another example, if a certain evidence service consumes a large amount of storage resources, which results in that the storage device carried by a certain blockchain node is nearly fully loaded, at this time, it will be impossible to provide storage space for a new block, which results in that blockchain service is suspended, and even if the computing resources of the blockchain node are still idle, they cannot be utilized.
Based on this, the present specification proposes a technical solution for separately managing and deploying the storage resources and the computing resources of the blockchain nodes, so as to avoid that one of the two nodes reaches a bottleneck in advance, which results in that the other node is idle and wasted.
During implementation, in the process of initializing the blockchain nodes, the intelligent contract operating environment of the blockchain nodes and the distributed account book can be separated and deployed in two computers, and then the two computers are combined to be used as a target blockchain link point to be added into a blockchain network in a network connection mode.
In the above technical solution, when initializing a block chain node, an intelligent contract operating environment of the block chain node is separated from a distributed account book and deployed in two computers, and then the two computers are combined as a target block chain link point to be added into a block chain network in a network connection manner, so that the separation of calculation and storage is realized within the block chain node, and thus, storage resources or calculation resources of the block chain node can be respectively adjusted, and a situation that one of the storage resources and the calculation resources is always wasted in a conventional initialization scheme is avoided;
in addition, due to the adoption of the scheme, the internal computing resources and the internal storage resources of the block chain nodes can be separated, so that the expansion and the migration of the storage resources of the block chain nodes can be more flexible, and the method can better adapt to the complex block chain service change.
The present specification is described below by using specific embodiments and with reference to specific application scenarios.
Referring to fig. 2, fig. 2 is a block chain node initialization method according to an embodiment of the present disclosure, where the method includes the following steps:
s201, deploying a distributed account book of block link points in a first computer;
s202, deploying an intelligent contract running environment of the blockchain nodes in the second computer;
s203, establishing a network connection between the first computer and the second computer, so that the first computer and the second computer jointly serve as a target block link point to join the block chain network.
The block chain can refer to a block chain of any shape and type; in this specification, a blockchain is also called as a distributed book accounting technology, and is a technology in which a plurality of computing devices participate in accounting together and maintain a complete distributed database together; in general, blockchains have the property of being decentralized, transparent to disclosure, capable of participating in database records per computing device, and capable of fast data synchronization between computing devices. Blockchains are generally divided into three types: public chain (Public Blockchain), Private chain (Private Blockchain) and alliance chain (Consortium Blockchain). In addition, there may be a combination of the above types, such as private chain + federation chain, federation chain + public chain, and so on. In general, various types of blockchain properties may differ, and thus may be used to meet different technical requirements; for example, if the highest degree of decentralization is desired, a public chain may be selected; federation chains, etc., may be selected if desired to compromise decentralization and performance. In implementation, if the blockchain is in a form of a federation chain, the blockchain nodes constituting the blockchain may be provided by various entities such as a relevant management department, a common user, a network operator, and the like, respectively, so as to ensure that the block chain billing right is relatively fair and reasonable; for another example, if the block chain is in a general programmable block chain form, the corresponding and general intelligent contract can be used for constructing related functions, and higher reliability can be obtained; it can be seen that various forms of blockchains have advantages, and those skilled in the art can select the type of blockchain according to specific needs, and the description does not limit the specific type of blockchain.
The first computer and the second computer may refer to any form and kind of computer, such as a conventional single server, or a server cluster, or a personal computer, or a smart phone, etc.; for example, if a service node has two computers, one of the computers a has higher computing performance and the other computer B has better storage expansion performance, the solution can be implemented by using the computer a as the second computer and the computer B as the first computer, so as to fully utilize resources.
It will be appreciated that, in addition to the physical computers in the conventional sense, virtual machines or containers bound to computer resources may be used as the first computer and the second computer through virtualization technology. Specifically, in a computer cluster, computing and storage resources of the computer cluster may often be scheduled by a container management engine to obtain a virtual machine whose performance index meets a service requirement; for example, in a kubernets-based computing cluster, a Pod with sufficient storage resources may be designed as the first computer, and a Pod with sufficient computing resources may be designed as the second computer.
In this specification, a distributed ledger of blockchain nodes may be deployed in a first computer, and an intelligent contract execution environment of blockchain nodes may be deployed in a second computer; specifically, since the block chain node can be theoretically divided into computer hardware for executing software codes and computer software codes for providing the block chain node function after being executed; when the above steps are implemented, the intelligent contract operating environment software code with a preference to the computing function of the blockchain node may be deployed in the second computer, and the distributed ledger software code with a preference to the storage function of the blockchain node may be deployed in the first computer, so that the blockchain node software codes originally running at one location are separately operated and have respective hardware resource support.
It is understood that if the first computer and the second computer are not physical computers, but virtual machines or containers divided based on virtualization technology, the first computer and the second computer may still run on the same physical hardware (e.g., a computer cluster); however, when the virtual machine or the container is partitioned by using the virtualization technology, the computer cluster performs allocation scheduling on resources such as computation and storage by using the management engine, and thus the first computer and the second computer can still be regarded as two computers with relatively separated hardware resources.
It should be clear that, in this specification, the above steps S201 and S202 are not strictly limited in order, that is, the above step S201 may be executed first and then the above step S202 is executed, the above step S202 may be executed first and then the above step S201 is executed, or both of them may be executed in parallel, or the like; the change of the specific execution timing of the two steps does not affect the final technical effect of the scheme disclosed in the specification.
In this specification, after the steps S201 and S202 are completed, a network connection may be established between the first computer and the second computer, so that the first computer and the second computer jointly join a blockchain network as a target blockchain link point. Specifically, since the blockchain account book of the blockchain node and the intelligent contract execution environment of the blockchain node are respectively deployed in the first computer and the second computer, therefore, the two computers can be connected by a network connection mode, so that the block chain distributed ledger deployed in the first computer can provide data access service for the intelligent contract execution environment deployed in the second computer, and the intelligent contract execution environment in the second computer may also provide computing services to the blockchain distributed ledger deployed in the first computer, and, therefore, after the two computers are successfully connected through the network, the two computers can jointly complete the tasks required to be completed as a block link point, so that, the two computers can be combined to be used as a target blockchain node to be added into a blockchain network.
From the external perspective of the target blockchain node, the process, that is, the process of initializing the target blockchain node and adding a blockchain network, is not particularly different from a conventional networking mode, and therefore, the scheme disclosed in the specification for performing partition design inside the blockchain link node can be almost compatible with any existing blockchain networking technology.
It should be noted that although the roll up technology exists in the related art, it is also mentioned that the computation task and the storage task of the block chain are completed separately, in a typical roll up technology scenario, it is a common practice to newly create another sub-chain for supporting the separated computation task, call the sub-chain as an intelligent contract executor of a main chain, and only store the input and the output of the computation task on the main chain. Under the scheme, although the subchain used for calculation can be verified by the verification content in the main chain in theory, after all, the consensus range of the calculation process is narrowed from the main chain to the subchain, and the reliability of block chain calculation is substantially reduced.
Compared with the roll technology, the method has the advantages that another sub-chain is not newly established, but segmentation and recombination are directly performed inside the block chain node, the process that the block chain node is added into the block chain network is not influenced, and the reliability of block chain calculation can still be guaranteed by a consensus mechanism of the whole block chain network; the trustworthiness of blockchain computation is not affected as in conventional Rollup solutions.
In an embodiment shown, the first computer may further include code for implementing other functions in the software code of the blockchain node; specifically, before the target blockchain node joins the blockchain network, a consensus algorithm code of the blockchain node, a blockchain network communication code, and an authentication code may be deployed in the first computer; when the first computer and the second computer need to join the blockchain network as a target blockchain link point, after the first computer establishes a network connection with the second computer, a join request may be sent to the blockchain network based on a blockchain network communication code deployed in the first computer, an authority verification may be performed through an authentication code deployed in the first computer, and after the authority verification passes, a consensus of the blockchain network may be participated in based on a consensus algorithm code deployed in the first computer.
It is understood that, in the first computer, the sequence relationship between the procedures of deploying the consensus algorithm code of the blockchain node, the blockchain network communication code, and the authentication code and the steps S201 and S202 does not need to be strictly defined; the specification only requires that the software codes of the blockchain nodes are deployed before the first computer and the second computer are combined to be used as a target blockchain link point to be added into the blockchain network.
Generally, the consensus algorithm code, the blockchain network communication code, and the authentication code of the blockchain node are closer to the distributed book function of the blockchain node, so that the codes are deployed in the first computer, the performance of the first computer can be fully utilized to a certain extent, and the overall operation efficiency of the blockchain node is improved; it is to be understood that the consensus algorithm code of the blockchain node, the blockchain network communication code, and the authentication code are not only deployed in the first computer, but also in the second computer, or in another third computer, or separately deployed in the plurality of computers; the software codes of the block chain nodes are only required to be ensured to be capable of realizing communication and exchange with each other when being executed, and the functions of the block chain nodes can be realized.
In another embodiment shown, the target blockchain node may be a blockchain node that can be controlled by a user through a user command; to achieve the object, a user interaction interface of a blockchain node may be deployed in a third computer, and a network connection between the third computer and the first computer and the second computer may be established, so that the user interaction interface has a function of performing a corresponding interaction operation on the target blockchain link point in response to a user instruction.
By applying the scheme, the user interaction interface is independently arranged in the third computer, so that the performance waste of the monitoring user operation on the first computer and the second computer can be reduced, and when the fault causing downtime occurs on the user interaction interface, the negative influence on the first computer and the second computer can be avoided by disconnecting the third computer, and the service availability on the link of the target block link node is ensured.
It will be appreciated that the aggregator, as a functional module for organizing the traffic of the user towards the blockchain node, may also be deployed in the third computer as described above, since it is strongly associated with the functionality of the user interface. Referring to fig. 3, fig. 3 is a diagram illustrating a structure and interaction example of a block link point; in this example, the aggregator and the user interface are disposed in the third computer, i.e., the oval portion in fig. 3, the execution environment for executing the smart contract, which may also be referred to as an executor, is disposed in the second computer, i.e., the rounded rectangular portion in fig. 3, and the consensus, authentication, chain storage (distributed ledger), network, etc. function modules may be disposed in the first computer, i.e., the large circular portion in fig. 3; since the user interface is deployed in the third computer, the user can interact with the target blockchain node through the third computer (elliptical portion); since the network function module is deployed at the first computer (the large circular portion), other nodes in the blockchain network can interact with the target blockchain node through the first computer.
It will be appreciated that since the intelligent contract execution environment portion for which the second computer is responsible has a relatively separate nature in terms of traffic functionality from the chain storage portion for which the first computer is responsible, the first computer portion may be referred to as L1, the first tier, of the target blockchain node, and the second computer portion may be referred to as L2, the second tier, of the target blockchain node.
In one embodiment, the first computer and the second computer may be computing clusters respectively; that is, the first computer may be a first computing cluster, and the second computer may be a second computing cluster. By adopting the scheme, different functional modules of one target block chain node can be respectively arranged in the two computing clusters, although the delay of information exchange in the node is increased, the better resource scheduling effect can be obtained by utilizing the different configuration characteristics of the two computing clusters. For example, the first computing cluster is a high storage capacity service cluster provided by a provider X, and the second computing cluster is a high computing power service cluster provided by a provider Y, and the sum of the two offers is still lower than the offer of a provider Z providing a high storage capacity, high computing power high-end service cluster, so that the high storage capacity service cluster provided by the provider X is used as the first computing cluster, the high computing power service cluster provided by the provider Y is used as the second computing cluster, and the solution described in this specification is deployed, thereby achieving the effects of reducing cost and improving resource utilization rate.
In an embodiment shown in the foregoing, the target block chain node may further adjust its storage resource according to a resource adjustment request; it is to be understood that, in this specification, the storage class resource of the target blockchain node is mainly provided by the first computer, and therefore, the storage class resource adjustment request may be received first; and increasing or decreasing the storage resources of the distributed ledger supporting the block nodes in the first computing cluster based on the reserve adjustment parameters carried in the storage resource expansion request.
For example, if the first computing cluster is a Kubernetes-based computing cluster, the storage class resource of the first computing cluster for supporting the distributed ledger of the block-node nodes may be increased or decreased by allocating available resources of Pod.
Similarly, in another embodiment, the target block link node may further adjust the computational resource according to the resource adjustment request; it is understood that, in this specification, the computing resources of the target blockchain node are mainly provided by the second computer, and therefore, the computing resource adjustment request may be received first; and increasing or decreasing the computing resources of the intelligent contract operating environment for supporting the block chain nodes in the second computing cluster based on the computing power adjustment parameters carried in the computing resource adjustment request. Similarly, if the second computing cluster is a Kubernetes-based computing cluster, the computing-class resources of the intelligent contract execution environment for supporting the blockchain node in the second computing cluster may be increased or decreased by the deployment of the available resources of the Pod.
It can be understood that, when the computing resources for supporting the intelligent contract operating environment of the blockchain node and/or the storage resources for supporting the distributed book of the blockchain node are adjusted, the available resource attributes of the existing container or virtual machine may be adjusted, or the number of containers/virtual machines for implementing the above functions may be directly adjusted.
For example, referring to fig. 4, fig. 4 is a block link point structure interaction diagram illustrating an example in which a first computer may be connected to a plurality of second computers; in this example, for temporarily increased high computing power requirements, several copies of the second computer may be added, and the computing task is fragmented, e.g., by App attribution of the computing task, which may enable one first computer to connect with multiple second computers; that is, one L1 of the target blockchain node may interface multiple L2.
For another example, referring to fig. 5, fig. 5 is an interactive illustration of a block link point structure that a second computer can be connected to a plurality of first computers; in this example, for temporarily increased high storage demand, copies of several first computers may be added, splitting the storage task to completion so that one second computer may connect with multiple first computers, i.e., one L2 of the target blockchain node may interface with multiple L1.
It is understood that, if the service is complex, the above two examples can be implemented simultaneously, that is, multiple L2 of the target block chain node can interface multiple L1, and so on, and this specification need not be further enumerated. Based on the above example of resource adjustment, it can be seen that, when the solution described in this specification is applied in a computing cluster environment, since the available resources in the computer cluster for the partitioned container or virtual machine can be flexibly adjusted, the computing resources of the intelligent contract operating environment supporting the blockchain node and/or the storage resources of the distributed book supporting the blockchain nodes can be adjusted in a more efficient manner.
