Description

Technical Field

[0001] The present application relates to the field of Internet technology, and in particular to a data processing method, device, and readable storage medium based on blockchain. Background Art

[0002] A smart contract is an automated program based on blockchain technology that can execute transactions and agreements without an intermediary. It has the characteristics of decentralization, transparency, security, and programmability.

[0003] In the prior art, the execution calculation of smart contracts is performed on local nodes. Usually, the block-producing node first executes the transaction through the smart contract, then generates the block and sends the block to other consensus nodes, and other consensus nodes call the smart contract to execute the transaction again. Obviously, in the prior art, when the block-producing node calls the smart contract to execute the transaction, the computing resources of other consensus nodes are idle. Similarly, when other consensus nodes call the smart contract to execute the transaction, the computing resources of the block-producing node are idle. Therefore, using the prior art, the resource utilization rate of all blockchain nodes is low; in addition, if the idle computing resources of the block-producing node or other consensus nodes are insufficient, the execution of the transaction will be reduced, and then the speed of the transaction on the chain will be reduced.

[0100] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0101] To facilitate understanding, some nouns are briefly explained as follows:

[0102] 1. Blockchain: In a narrow sense, blockchain is a chain data structure with blocks as the basic unit. The digital summary is used in the block to verify the transaction history previously obtained, which is suitable for the needs of tamper-proof and scalability in the distributed accounting scenario; in a broad sense, blockchain also refers to the distributed accounting technology implemented by the blockchain structure, including distributed consensus, privacy and security protection, peer-to-peer communication technology, network protocols, smart contracts, etc. The goal of the blockchain is to realize a distributed data record book, which only allows additions but not deletions. The basic structure of the underlying ledger is a linear linked list. The linked list is composed of "blocks" connected in series, and the hash value of the previous block is recorded in the subsequent block. Whether each block (and the transactions in the block) is legal can be quickly verified by calculating the hash value. If a node in the network proposes to add a new block, it must reach a consensus on the block through the consensus mechanism.

[0103] 2. Blockchain nodes: The blockchain network divides nodes into consensus nodes (also called core nodes) and synchronization nodes (which may include data nodes and light nodes). Among them, the consensus node is responsible for the consensus business of the entire blockchain network; the embodiment of the present application refers to the consensus node with the authority to generate blocks (i.e., generate blocks to be agreed upon) as the block node. The synchronization node is responsible for synchronizing the ledger information of the consensus node, that is, synchronizing the latest block data. Whether it is a consensus node or a synchronization node, its internal structure includes a network communication component, because the blockchain network is essentially a peer-to-peer network, and it needs to communicate with other nodes in the blockchain network through peer-to-peer components. The resources and services in the blockchain network are scattered on each node, and the transmission of information and the implementation of services are carried out directly between nodes without the intervention of intermediate links or centralized servers (third parties).

[0104] 3. Block: It is a data packet that carries transaction data on the blockchain network. It is a data structure marked with a timestamp and the hash value corresponding to the previous block. The block is verified and confirmed by the consensus mechanism of the network. The block includes a block header and a block body. The block header can record the meta information of the current block, including the current version number, the hash value corresponding to the previous block, the timestamp, the random number, the hash value of the MerkleRoot, and other data. The block body can record the detailed data generated within a period of time, including all transaction records or other information generated during the block creation process that have been verified by the current block, which can be understood as a form of account book. In addition, the detailed data of the block body can include the unique Merkle Root generated through the hash process of the Merkle Tree and recorded in the block header.

[0105] 4. Hash value: Also known as information characteristic value or characteristic value, the hash value is generated by converting input data of any length into a password and performing a fixed output through a hash algorithm. The original input data cannot be retrieved by decrypting the hash value. It is a one-way encryption function. In the blockchain, each block (except the initial block) contains the hash value of the previous block. The hash value is the potential core foundation and the most important aspect of blockchain technology. It retains the authenticity of the recorded and viewed data, as well as the integrity of the blockchain as a whole.

[0106] 5. Public key and private key: Public key and private key are a key pair obtained through an algorithm. The public key is the public part of the key pair, and the private key is the non-public part. The public key is usually used to encrypt data, verify digital signatures, etc. This algorithm can ensure that the key pair obtained is unique. When using this key pair, if one of the keys is used to encrypt a piece of data, the other key must be used to decrypt it. For example, if the data is encrypted with the public key, it must be decrypted with the private key. If it is encrypted with the private key, it must also be decrypted with the public key, otherwise the decryption will not be successful.

[0107] 6. Asymmetric signature: The signature algorithm includes two keys, a public key (public key for short) and a private key (private key for short). The public key and the private key are a pair. If the private key is used to sign data, the signature can only be verified with the corresponding public key. Because the signing process and the verification process use two different keys, this algorithm is called an asymmetric signature. The basic process of asymmetric signature to achieve confidential information exchange can be: Party A generates a pair of keys and makes the public key public. When Party A needs to send a message to another role (Party B), it uses its own private key to sign the confidential message and then sends it to Party B; Party B then uses Party A's public key to verify the signed message.

[0108] 7. Smart Contract: A computer protocol designed to disseminate, verify or execute contracts in an information-based manner. In a blockchain system, a smart contract (contract for short) is a code that can be understood and executed by each node of the blockchain, which can execute any logic and obtain results. In actual applications, smart contracts are managed and tried through transactions on the blockchain. Each transaction is equivalent to a remote procedure call (RPC) request to the blockchain system. If a smart contract is equivalent to an executable program, the blockchain is equivalent to an operating system that provides an operating environment. A blockchain can contain multiple contracts, distinguished by a contract account (Identity, ID), identification number or name.

[0109] 8. Cluster Resource Management System (Apache Mesos): It is an open source cluster manager that provides effective resource isolation and sharing, and can deploy multiple applications in a cluster. It has a highly modular design and can be easily expanded and integrated with other components. The core idea of ​​Mesos is to regard the entire data center or cloud environment as a large computing resource pool and realize multi-task scheduling and load balancing by dynamically allocating resources. Mesos can be used in scenarios such as big data processing, container orchestration, and microservice management.

[0110] 9. Mesos Framework: It is an application or service running on Mesos, which is responsible for communicating with the Mesos cluster to schedule and execute tasks in the cluster. A Framework usually consists of two components: Scheduler (scheduling) and Executor (execution). Scheduler is responsible for interacting with MesosMaster (master node), receiving resource quotations, issuing (Resource Offer) and deciding whether to accept; Executor is responsible for executing tasks on Mesos Slave (worker node). Common Mesos Frameworks include Marathon (for long-running services), Chronos (distributed timed task scheduler) and Apache Spark (big data processing framework).

[0111] It can be understood that the cluster resource management system in the embodiment of the present application is jointly maintained by all blockchain nodes, so the Framework in the embodiment of the present application is deployed on multiple blockchain nodes, including the contract service proposed in this application.

[0112] 10. Mesos Scheduler: It is a key component of the Framework, used to manage and schedule tasks in a Mesos cluster. It is the core part of a framework, responsible for communicating with the Mesos master node, receiving resource slices (ResourceOffers) and deciding how to allocate tasks to these resources. The main responsibilities of Mesos Scheduler include: communicating with the Mesos master node, receiving resource slices, managing task queues, allocating tasks, monitoring task status and implementing custom scheduling strategies. Mesos Scheduler can implement custom scheduling strategies based on specific application scenarios and requirements to optimize task execution performance and resource utilization. This application refers to Mesos Scheduler as a scheduling component.

[0113] 11. Mesos Executor: It is part of the Framework and is responsible for executing tasks on Mesos Slave nodes. When the Framework's Scheduler accepts a resource quotation, it sends the task to the corresponding Executor for execution. The Executor can be general or specific to an application. In some cases, the Executor can also be responsible for monitoring the running status of the task and reporting to the Scheduler. This application refers to the Mesos Executor as the execution component.

[0114] 12. Master: It is the core component of the Mesos cluster and is responsible for managing all resources and tasks in the cluster. The Master communicates with the Framework's Scheduler and each Slave node, and is responsible for resource allocation and task scheduling. The Master is also responsible for observing the state of the cluster, including the health of the nodes, resource usage, etc. In order to ensure high availability, Mesos usually deploys multiple Master nodes, which are elected through the ZooKeeper coordination service to select a leader to handle tasks in the cluster.

[0115] 13. Worker node (Slave, also called Agent): Responsible for executing tasks assigned by the Framework. Each Slave node runs a Mesos Agent process, which is responsible for communicating with the Master, reporting resource usage and receiving tasks. Resource isolation and management on Slave nodes are usually implemented through container technology (such as Docker) or Mesos's own container runtime (such as Mesos Containerizer).

[0116] In the embodiment of the present application, all blockchain nodes in the blockchain can be regarded as a node cluster, which jointly maintains a Mesos, that is, the present application deploys a cluster resource management system in the blockchain network, and regards all resources of all blockchain nodes as a large computing resource pool. From the consensus dimension, blockchain nodes can be divided into consensus nodes and synchronization nodes. In the cluster resource management dimension, blockchain nodes can be divided into master nodes and working nodes. Therefore, a blockchain node is a consensus node when it has consensus authority, and a master node when it has cluster resource management. In layman's terms, a blockchain node can be both a consensus node and a master node, but a consensus node and a synchronization node are not the same blockchain node, and a master node and a working node are not the same blockchain node.

[0117] See also Figure 1 , Figure 1 Schematic diagram of a system architecture provided by an embodiment of the present application. Figure 1 As shown, the system architecture may include a business server 101, a terminal device cluster and a blockchain node cluster 10.

[0118] The blockchain node cluster 10 may include one or more blockchain nodes, and the embodiment of the present application does not limit the number of blockchain nodes in the blockchain node cluster 10. Figure 1 As shown, the blockchain node cluster 10 may include a blockchain node 10a, a blockchain node 10b, a blockchain node 10c, and a blockchain node 10d.

[0119] It can be understood that when each blockchain node is performing normal work, it can receive data to be uploaded to the chain (such as the first transaction to be uploaded to the chain and the second transaction to be uploaded to the chain in the embodiment of the present application) sent by off-chain devices (referred to as business devices in this application, such as the business server 101 in the embodiment of the present application and the terminal devices in the terminal device cluster), and generate blocks based on the received data to be uploaded to the chain, and then process the blocks on the chain.

[0120] It is understandable that in the specific implementation of the present application, related data such as user information (such as the first transaction to be on-chain and the second transaction to be on-chain) is involved. When the embodiment of the present application is applied to a specific product or technology, it is necessary to obtain user permission or consent, and the collection, use and processing of the relevant data need to comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0121] In order to ensure data intercommunication between various blockchain nodes, there may be a data connection between each blockchain node, for example, there is a data connection between blockchain node 10a and blockchain node 10c, there is a data connection between blockchain node 10a and blockchain node 10d, there is a data connection between blockchain node 10b and blockchain node 10c, and so on. It is understandable that data or blocks can be transmitted between blockchain nodes through the above data connection. The data connection between the above blockchain nodes can be based on node identification. For each blockchain node in the blockchain network, there is a node identification corresponding to it, and each of the above blockchain nodes can store the node identification of other blockchain nodes that are connected to itself, so that the acquired data or generated blocks can be broadcast to other blockchain nodes according to the node identification of other blockchain nodes. For example, blockchain node 10a can maintain a node identification list, which stores the node names and node identifications of other blockchain nodes, as shown in Table 1.

[0122] Table 1

[0123] Node Name Node ID Blockchain Node 10b AAAAA Blockchain Node 10c BBBBB … … Blockchain Node 10d CCCCC

[0124] Among them, the node identifier can be the Internet Protocol (IP) address for interconnecting networks, or any other information that can be used to identify a node in a blockchain network. Table 1 only uses the IP address as an example for explanation.

[0125] Assuming that the node identifier of blockchain node 10a is FFFFFF, blockchain node 10a can send transaction data to blockchain node 10d through node identifier CCCCC, and blockchain node 10d can determine that the transaction data is sent by blockchain node 10a through node identifier FFFFFF; similarly, blockchain node 10d can send a block to be agreed upon to blockchain node 10c through node identifier BBBBBB, and blockchain node 10c can determine that the block to be agreed upon is sent by blockchain node 10d through node identifier CCCCCC, and the same is true for data transmission between other nodes, so they will not be elaborated one by one.

[0126] It is understandable that the above-mentioned data connection does not limit the connection method, and can be directly or indirectly connected through wired communication, directly or indirectly connected through wireless communication, or through other connection methods, which are not limited in this application.

[0127] Among them, it is understandable that Figure 1 The blockchain nodes 10a, 10b, 10c, and 10d shown may have a one-to-one correspondence with the corresponding roles (i.e., entity objects in the corresponding business scenarios) that need to be connected to the blockchain network. The business scenarios here may specifically include electronic bill scenarios, resource issuance scenarios, resource transfer scenarios, payment scenarios, etc. At this time, the business data information in the corresponding business scenarios may specifically include electronic bill information in the electronic bill scenario, resource issuance information in the resource issuance scenario, resource transfer information in the resource transfer scenario, asset transfer records in the payment scenario, etc. The specific contents of the business data information in the corresponding business scenarios will not be listed one by one here.

[0128] It is understandable that the terminal device cluster may include one or more terminal devices, and the embodiment of the present application does not limit the number of terminal devices in the terminal device cluster. Figure 1As shown, the terminal device cluster may include terminal device 100a, terminal device 100b, terminal device 100c, ..., terminal device 100d. Among them, there may be a network connection between the terminal device clusters, for example, there is a network connection between terminal device 100a and terminal device 100b. At the same time, any terminal device in the terminal device cluster may have a network connection with the business server 101, for example, there is a network connection between terminal device 100d and business server 101. At the same time, any terminal device in the terminal device cluster may have a network connection with the blockchain network, for example, there is a network connection between terminal device 100b and blockchain node 10c in the blockchain network. Among them, the above-mentioned network connection does not limit the connection method, and can be directly or indirectly connected through a wired network, or directly or indirectly connected through a wireless network, or through other methods, and this application is not limited here.

[0129] It should be understood that Figure 1 Each terminal device in the terminal device cluster shown in FIG. 1 may be installed with an application client. When the application client runs in each terminal device, it may be respectively connected to the above-mentioned Figure 1 The business servers 101 shown in the figure can exchange data with each other, that is, the above-mentioned network connection; Figure 1 The blockchain network shown in the figure is used for data interaction. The application client can be a video application, a digital resource application, an office software application, a navigation application, a shopping application, a financial management application, a business application, a browser, and other application clients that have the function of sending data to be uploaded. The application client can be an independent client or an embedded sub-client integrated in a client (for example, an education client and a multimedia client, etc.), which is not limited here.

[0130] Taking digital resource application as an example, the business server 101 may be a collection of multiple servers including a background server corresponding to the digital resource application, a data processing server, etc. Therefore, each terminal device can transmit data with the business server 101 through the application client corresponding to the digital resource application. For example, each terminal device can upload a smart contract creation request to the business server 101 through the application client of the digital resource application, and then the business server 101 can transmit the smart contract creation request to the blockchain network.

[0131] The service server 101 may be a background server corresponding to the application client installed in the terminal device in the terminal device cluster. It is understandable that the above system may include one or more service servers, and the number of service servers is not limited here. Figure 1The business server 101 shown can be connected to the blockchain network so as to facilitate data interaction through the network connection with the blockchain network.

[0132] The service equipment in the embodiment of the present application may include Figure 1 Any terminal device in the terminal device cluster shown and the service server 101. To facilitate subsequent understanding and description, the embodiment of the present application can be Figure 1 A device is selected as a business device in the terminal device cluster or business server 101 shown, for example, terminal device 100c is used as a business device. When a transaction chain instruction for the first transaction to be chained is obtained in the application client bound to account a, the business device (such as terminal device 100c) can send the first transaction to be chained to the blockchain network through the application client.

[0133] For ease of description and understanding, the following description is based on an example of any blockchain node in the blockchain network, for example Figure 1 The blockchain node 10a in. When the first transaction to be on the chain is obtained, the blockchain node 10a verifies the legitimacy of the first transaction to be on the chain. If the first transaction to be on the chain is legitimate, the first transaction to be on the chain is added to the local transaction pool. When it has the authority to generate blocks, the blockchain node 10a (the blockchain node 10a is a block generating node at this time) obtains the first transaction to be on the chain from the transaction pool. If the first transaction to be on the chain is a transaction for installing a smart contract, the blockchain node 10a encodes the first transaction to be on the chain to obtain an encoded file; further, the encoded file is sent to the master node in the cluster resource management system, wherein the cluster resource management system is jointly maintained by all blockchain nodes in the blockchain network, and it can manage all computing resources and storage resources of all blockchain nodes.

[0134] The master node is a node in the cluster resource management system that is responsible for managing all resources and tasks in the cluster (this application refers to the blockchain node cluster). In layman's terms, the master node is one or more blockchain nodes in the blockchain node cluster. Therefore, one scenario is that the block-producing node (such as the above-mentioned blockchain node 10a with block-producing authority) and the master node can be different blockchain nodes. At this time, the block-producing node sends the encoded file to the master node; therefore, another scenario is that the block-producing node and the master node can be the same blockchain node. At this time, the block-producing node can create a contract service for the smart contract in the cluster resource management system based on the encoded file.

[0135] Further, the master node creates a contract service for the smart contract in the cluster resource management system according to the coding file; the contract service includes a scheduling component and A execution components running on A working nodes; A is a positive integer; wherein one working node is used to run one execution component; the master node and the A working nodes different from the master node are all blockchain nodes in the blockchain. The scheduling component can run on the master node or on the working node, which is not limited in the embodiment of the present application.

[0136] Further, the blockchain node 10a sends the first transaction to be on-chain to the scheduling component, so that the scheduling component allocates a first working node for the first transaction to be on-chain among A working nodes; the first working node is used to execute the first transaction to be on-chain in the first execution component; the first execution component refers to the execution component running on the first working node.

[0137] From the above, it can be seen that the embodiment of the present application can create a contract service for the smart contract in the cluster resource management system, and then the execution task corresponding to the first transaction to be on the chain can be transferred from the block producing node to the contract service, that is, the first transaction to be on the chain is executed by the first working node running the first execution component. Therefore, by adopting the present application, the resource utilization rate of all blockchain nodes can be improved, and then the efficiency of transaction on the chain can be improved.

[0138] The method provided in the embodiment of the present application can be executed by a computer device, which includes but is not limited to a terminal device or a business server. The business server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud database, cloud service, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN, and big data and artificial intelligence platform. Terminal devices include but are not limited to mobile phones, computers, intelligent voice interaction devices, smart home appliances, vehicle terminals, aircraft, etc.

[0139] For further information, see Figure 2 , Figure 2 This is a flowchart of a data processing method based on blockchain provided in an embodiment of the present application. Figure 1 The implementation process of the data processing method can be carried out in a blockchain node with block generation authority (hereinafter referred to as a block generation node), in a master node, in a blockchain node with a scheduling component in a contract service (hereinafter referred to as a scheduling node), or interactively in a block generation node, a master node, and a scheduling node, without limitation. The block generation node, the master node, and the scheduling node can be the above Figure 1 Any blockchain node in the blockchain node cluster of the corresponding embodiment. Figure 2The embodiments of the present application are described by taking a block node as an example. The embodiments of the present application can be applied to various scenarios, including but not limited to cloud technology, artificial intelligence, smart transportation, assisted driving, etc. Figure 2 As shown, the data processing method may at least include the following steps S101 to S103.

[0140] Step S101, obtaining the first transaction to be on-chain from the transaction pool. If the first transaction to be on-chain is a transaction for installing a smart contract, the first transaction to be on-chain is encoded to obtain an encoded file.

[0141] Specifically, the first transaction to be on-chain carrying the signature message sent by the contract installation account is obtained; the signature message is obtained by the contract installation account signing the first transaction to be on-chain through the business private key; the signature message is verified through the business public key corresponding to the contract installation account to obtain the signature verification result; if the signature verification result indicates that the signature message verification fails, a signature verification failure message is returned to the contract installation account; if the signature verification result indicates that the signature message verification succeeds, the contract installation account is subjected to permission verification to obtain the permission verification result; according to the permission verification result, the first transaction to be on-chain is added to the transaction pool.

[0142] Among them, the specific process of performing permission verification on the contract installation account and obtaining the permission verification result may include: obtaining a list of illegal accounts in the blockchain, and comparing the contract installation account with the illegal accounts in the illegal account list; when there is an illegal account identical to the contract installation account in the illegal account list, determining the account verification illegal result as the permission verification result; when there is no illegal account identical to the contract installation account in the illegal account list, performing contract installation function call permission verification on the contract installation account; if the contract installation account does not have the permission to call the contract installation function, determining the contract installation prohibited result as the permission verification result; if the contract installation account has the permission to call the contract installation function, determining the permission verification passed result as the permission verification result.

[0143] Among them, according to the permission verification result, the specific process of adding the first transaction to be on-chain to the transaction pool may include: if the permission verification result is an illegal account verification result or a contract installation prohibited result, then returning a permission verification failure message to the contract installation account; if the permission verification result is a permission verification passed result, then adding the first transaction to be on-chain to the transaction pool.

[0144] Specifically, if the first transaction to be on-chain is a transaction for installing a smart contract, the contract file corresponding to the smart contract is obtained in the first transaction to be on-chain; the contract file is generated by encoding the source code corresponding to the smart contract by the business device that initiates the first transaction to be on-chain; the contract file is detected and processed to obtain a file detection result. If the file detection result indicates that the contract file is of an abnormal type, a file detection exception message is returned to the business device; if the file detection result indicates that the contract file is of a normal type, the contract file is encoded and processed to obtain an encoded file.

[0145] Please also see Figure 3 , Figure 3 This is a schematic diagram of a data processing scenario based on blockchain provided by an embodiment of the present application. Figure 1 .like Figure 3 As shown, the service device 30a may be a terminal device, for example Figure 1 Any terminal device in the terminal device cluster in. Business device 30a is bound to a blockchain account (i.e., blockchain address, which is described as contract installation account 301a in this embodiment of the application), such as Figure 3 The example account is 222222. The business device 30a obtains the source code 301b corresponding to the smart contract. Figure 3 Taking the transfer contract as an example of a smart contract, the source code 301b may include the transfer-out account, the transfer-in account, and the transferred resource value. Further, the business device 30a encodes the source code 301b to obtain the contract file 302b corresponding to the smart contract, such as Figure 3 The example shown is 00…01…11.

[0146] It should be noted that the contract file, source code and the coded file described below are all used to indicate smart contracts, which can be understood as different expressions of smart contracts. For example, source code 301b is a code written by a technician using a computer programming language (such as C / C++ language), contract file 302b is a code obtained by encoding source code 301b by business device 30a, and the coded file mentioned below is a code obtained by encoding contract file 302b by a block node. Among them, the coding method includes but is not limited to compilation and packaging, and compilation can convert high-level languages ​​into binary languages ​​that can be recognized by computers.

[0147] Obviously, the contract file 302b is used to install the smart contract (such as Figure 3 Therefore, the business device 30a needs to obtain the parameters that define the smart contract initialization method, such as Figure 3 The illustrated initial method parameters 303b, which correspond to the source code 301b, may include the transfer account number (i.e. Figure 3Transfer out: 222222), transfer to account (ie Figure 3 333333), transfer resource value (i.e. Figure 3 Further, the business device 30a determines the contract file 302b and the initial method parameter 303b as the first transaction to be on-chain, and installs the contract account 301a (such as Figure 3 The business public key 301c corresponding to the example account 222222) signs the first transaction to be on the chain to obtain the signed message 302c; through the contract installation account 301a, the business device 30a sends the first transaction to be on the chain carrying the signed message 302c to the blockchain network 10.

[0148] It is understandable that each blockchain node in the blockchain network 10 will add the first transaction to be on-chain to its own transaction pool, that is, each blockchain node will perform the same steps and then add the first transaction to be on-chain to its own transaction pool. The transaction pool of the blockchain refers to a collection of transactions that are not packaged into the block and are waiting to be written into the block. In the blockchain network, each node maintains a transaction pool to store new transactions generated by business objects. When a business object initiates a transaction, the transaction will be broadcast to the entire blockchain network; if the transaction complies with the transaction rules and verification rules of the blockchain network, it will be added to the transaction pool of the blockchain node. Transactions in the transaction pool need to wait for verification and confirmation before waiting to be packaged into the block. The transaction pool is one of the important components of the blockchain network. While ensuring that transactions are processed smoothly, it can also improve the efficiency and performance of the blockchain.

[0149] The present application embodiment is described by taking the blockchain node 10a in the blockchain network 10 as an example. Figure 3 As shown, the blockchain node 10a obtains the first transaction to be on-chain that carries the signature message 302c, and verifies the signature message 302c through the business public key 303c corresponding to the contract installation account 301a to obtain the signature verification result. If the signature verification result indicates that the signature message 302c fails to be verified, the blockchain node 10a returns a signature verification failure message to the business device 30a bound to the contract installation account 301a; if the signature verification result indicates that the signature message 302c is successfully verified, the illegal account list 30d is obtained in the blockchain. Among them, the illegal account list 30d includes blockchain accounts with illegal attributes, such as Figure 3 As shown, the illegal account list 30d includes illegal accounts 222220, ..., illegal account 222221.

[0150] Further, blockchain node 10a installs the contract account 301a (such as Figure 3The example account 222222) is compared with the illegal account in the illegal account list 30d; when there is an illegal account identical to the contract installation account 301a in the illegal account list 30d, the blockchain node 10a determines the account verification illegal result as the authority verification result; when there is no illegal account identical to the contract installation account 301a in the illegal account list 30d, the contract installation account 301a is subjected to the contract installation function 30e calling authority verification processing, that is, verifying whether the contract installation account 301a has the authority to call the contract installation function 30e (i.e., the method of creating a contract). If the contract installation account 301a does not have the authority to call the contract installation function 30e, the blockchain node 10a determines the contract installation prohibition result as the authority verification result; if the contract installation account 301a has the authority to call the contract installation function 30e, the authority verification pass result is determined as the authority verification result.

[0151] Please see again Figure 3 If the permission verification result is an illegal account verification result or a contract installation prohibition result, the blockchain node 10a returns a permission verification failure message to the business device 30a; if the permission verification result is a permission verification pass result, the first transaction to be on-chain is added to the transaction pool 30g, such as Figure 4 As shown, Figure 4 This is a schematic diagram of a data processing scenario based on blockchain provided by an embodiment of the present application. Figure 2 .

[0152] When the blockchain node 10a has the authority to generate blocks, the blockchain node 10a, as a block generating node, obtains a batch of transactions to be uploaded from the transaction pool 30g. It is assumed that the batch of transactions to be uploaded includes the first transaction to be uploaded. The blockchain node 10a detects the transaction type of the first transaction to be uploaded. If the transaction type is determined to be a contract installation transaction type, that is, the first transaction to be uploaded is detected to be a transaction for installing a smart contract, the blockchain node 10a obtains the contract file 302b in the first transaction to be uploaded. Figure 4 As shown, the blockchain node 10a detects and processes the contract file 302b, specifically, detects whether the contract file 302b can be started normally, and whether there are loopholes and security issues.

[0153] If the file detection result indicates that the contract file 302b is of an abnormal type, for example, the contract file 302b cannot be started normally or has a vulnerability, the blockchain node 10a returns a file detection exception message to the business device 30a; if the file detection result indicates that the contract file 302b is of a normal type, the contract file is encoded to obtain an encoded file 30h. The encoding process is to obtain a file that can be run in the cluster resource management system, that is, the encoded file 30h. The encoded file 30h can be a compressed package file, that is, a tar file.

[0154] Step S102, sending the encoded file to the master node in the cluster resource management system, so that the master node creates a contract service for the smart contract in the cluster resource management system according to the encoded file; the contract service includes a scheduling component and A execution components running on A working nodes; A is a positive integer; wherein one working node is used to run one execution component; the master node and the A working nodes different from the master node all belong to blockchain nodes in the blockchain.

[0155] For details, please refer to Figure 4 The blockchain node 10a with block-generating authority (referred to as the block-generating node) sends the encoded file 30h to the master node in the cluster resource management system 30i. The cluster resource management system 30i is jointly maintained by all blockchain nodes in the blockchain network. The embodiment of the present application does not limit the number of master nodes, which can be one or more. Figure 4 The example cluster resource management system 30i includes two master nodes, namely, blockchain node 10d and blockchain node 10a. It can be understood that the master node refers to the blockchain node in the cluster resource management system 30i, which is used to manage all resources and tasks in the blockchain node cluster. If there are multiple master nodes (Master), the multiple master nodes are elected through the distributed application (ZooKeeper) coordination service to select a leader (Leader) to handle the tasks in the cluster. The embodiment of the present application uses the blockchain node 10d as an example of the Leader node, which can be understood as the master node that is truly used to manage the blockchain node cluster. The relationship between the Leader node and multiple master nodes can be equivalent to the block node and multiple consensus nodes, that is, the block node is a consensus node with block authority among the consensus nodes. Among them, according to whether it has consensus authority, the blockchain node can be divided into a consensus node and a synchronization node, and according to whether it has the authority to manage the cluster, the blockchain node can be divided into a master node and a working node. It can be understood that the consensus authority and the management cluster authority are two different division criteria.

[0156] Please see again Figure 4 , the master node (such as Figure 4 The blockchain node 10d of the embodiment creates a contract service 30j for the smart contract in the cluster resource management system 30i according to the encoding file 30h. It can be understood that the contract service 30j (Framework) is an application running on Mesos, which can implement resource allocation and elastic expansion algorithms, including a scheduling (Scheduler) component and A execution (Executor) components. The embodiment of the present application does not limit the value of A, which can be a positive integer. Figure 4Example A is equal to 2, that is, the contract service 30j includes two execution components, namely, execution component 1 and execution component 2. Among them, execution component 1 runs on blockchain node 10b (a working node different from the master node), and execution component 2 runs on blockchain node 10c (another working node different from the master node).

[0157] Step S103, sending the first transaction to be on-chain to the scheduling component, so that the scheduling component allocates a first working node for the first transaction to be on-chain among A working nodes; the first working node is used to execute the first transaction to be on-chain in the first execution component; the first execution component refers to the execution component running on the first working node.

[0158] Specifically, the embodiment of the present application does not limit the node where the scheduling component is installed. The scheduling component in the contract service can be run by the master node or by the working node. The embodiment of the present application uses the working node to run the scheduling component. Please refer to Figure 5 , Figure 5 This is a schematic diagram of a data processing scenario based on blockchain provided by an embodiment of the present application. Figure 3 .like Figure 5 As shown, the block node (i.e. Figure 5 The blockchain node 10a in the example sends the first transaction to be uploaded to the blockchain to the working node (i.e. Figure 5 Example blockchain node 10b). Through the scheduling component, the blockchain node 10b as a working node can be in two working nodes (i.e. Figure 4 In the example blockchain node 10b and blockchain node 10c), the first working node is assigned to the first transaction to be on-chain. The first working node in the example of the embodiment of the present application is blockchain node 10b. Further, blockchain node 10b as the first working node executes the first transaction to be on-chain through the first execution component (i.e., the above-mentioned execution component 1).

[0159] As can be seen from the above, load balancing can be achieved by using the embodiments of the present application. Load balancing is a method of distributing workloads between multiple computing resources (such as servers, network connections, or other devices) so as to balance processing tasks on different resources. The main purpose of load balancing is to optimize resource utilization, maximize throughput, minimize response time, avoid resource overload, and ensure the availability and reliability of the system. Load balancing can be applied to different systems and scenarios, such as network load balancing, server load balancing, and database load balancing. Load balancing can be achieved through hardware devices (load balancers) or software solutions (such as proxy servers or applications).

[0160] From the above, it can be seen that the embodiment of the present application can create a contract service for the smart contract in the cluster resource management system, and then the execution task corresponding to the first transaction to be on the chain can be transferred from the block producing node to the contract service, that is, the first transaction to be on the chain is executed by the first working node running the first execution component. Therefore, by adopting the present application, the resource utilization rate of all blockchain nodes can be improved, and then the efficiency of transaction on the chain can be improved.

[0161] For further information, see Figure 6 , Figure 6 This is a flow diagram of a data processing method provided in an embodiment of the present application. Figure 2 The implementation process of the data processing method can be performed in the block node, the master node, the scheduling node, or interactively in the block node, the master node, and the scheduling node, which is not limited here. Figure 1 Any blockchain node in the blockchain node cluster of the corresponding embodiment. Figure 6 The embodiment of the present application is described by taking a block-producing node as an example. Figure 6 As shown, the data processing method may at least include the following steps S201 to S206.

[0162] Step S201, obtaining the first transaction to be on-chain from the transaction pool. If the first transaction to be on-chain is a transaction for installing a smart contract, the first transaction to be on-chain is encoded to obtain an encoded file.

[0163] Step S202, sending the encoded file to the master node in the cluster resource management system, so that the master node creates a contract service for the smart contract in the cluster resource management system according to the encoded file; the contract service includes a scheduling component and A execution components running on A working nodes; A is a positive integer; wherein one working node is used to run one execution component; the master node and the A working nodes different from the master node all belong to blockchain nodes in the blockchain.

[0164] For the specific implementation process of step S201-step S202, please refer to the above Figure 2 The description of step S101 - step S102 in the corresponding embodiment is not repeated here.

[0165] Step S203, sending the first transaction to be on-chain to the scheduling component, so that the scheduling component allocates a first working node for the first transaction to be on-chain among A working nodes; the first working node is used to execute the first transaction to be on-chain in the first execution component; the first execution component refers to the execution component running on the first working node.

[0166] Specifically, the historical reputation value of the first working node is obtained. If the first transaction execution result generated by the first working node after executing the first transaction to be on-chain is obtained, the reputation reward value is obtained according to the first transaction execution result; the first transaction to be on-chain and the first transaction execution result are used to generate a first block to be agreed upon; the reputation reward value is added to the historical reputation value to obtain an updated reputation value of the first working node; if the first working node fails to successfully execute the first transaction to be on-chain, the reputation penalty value is obtained, and the reputation penalty value is added to the historical reputation value to obtain an updated reputation value of the first working node; wherein the updated reputation value of the first working node is used to instruct the scheduling component to determine the working component for executing the transaction to be on-chain among A working nodes.

[0167] This step may also include: comparing the updated reputation value of the first working node with the reputation threshold; if the update threshold of the first working node is less than or equal to the reputation threshold, deleting the first working node in the blockchain; if the update threshold of the first working node is greater than the reputation threshold, retaining the first working node in the blockchain.

[0168] Please see again Figure 5 , through the first execution component (such as Figure 5 In the example execution component 1), the blockchain node 10b as the first working node can execute the first transaction to be on-chain, specifically Figure 3 The example initial method parameters 303b are input to Figure 3 The exemplary contract file 302b is executed.

[0169] If the first transaction to be on-chain is successfully executed through the first execution component and the first transaction execution result is obtained, the first working node (i.e. Figure 5 The blockchain node 10b in returns the first transaction execution result to the block producing node (i.e. Figure 5 At this time, the blockchain node 10a obtains the historical reputation value of the first working node, Figure 5 The example historical reputation value is 2. Further, according to the first transaction execution result, the blockchain node 10a obtains the reputation reward value. Figure 5 The example reputation reward value is 1; the reputation reward value is added to the historical reputation value, for example 2+1, so the blockchain node 10a can obtain the updated reputation value of the first working node, such as Figure 5 3 shown.

[0170] If the first working node fails to successfully execute the first transaction to be uploaded, the block generating node (such as Figure 5 The blockchain node 10a) obtains the reputation penalty value, Figure 5The example reputation penalty value is -1, and the reputation penalty value is added to the historical reputation value, for example 2-1. The blockchain node 10a can obtain the updated reputation value of the first working node, such as Figure 5 1 shown. Among them, the updated reputation value of the first working node is used to instruct the scheduling component to determine the working component for executing the transaction to be on-chain among the A working nodes.

[0171] In addition, after obtaining the first transaction execution result, the blockchain node 10a as a block-producing node can generate a first block to be agreed upon based on the first transaction to be on-chain and the first transaction execution result; further, the first block is broadcast to the remaining consensus nodes in the blockchain network, and the remaining consensus nodes perform consensus processing on the first block to obtain a consensus result. If the consensus node is a consensus passing result, the blockchain node 10a stores the first block and updates the data in the state database. If the consensus result is a consensus failure result, the first block is deleted.

[0172] This step proposes an intelligent scheduling strategy based on the reputation of blockchain nodes. Some blockchain nodes may have poor stability or malicious behavior. For these blockchain nodes, they are evaluated by reputation. When allocating Mesos resource slices, tasks are assigned to nodes with high reputation scores, and nodes with extremely low reputation scores can be kicked out to maintain the stability of the blockchain network.

[0173] Through the above scheme, the present application can ensure that multiple computing nodes reuse computing resources, avoiding the problem of insufficient resources of a single blockchain node, resulting in slow computing; in addition, by ensuring that the number of Executors can be expanded horizontally, the present application can adapt when the number of contract tasks changes; in addition, the present application can ensure that nodes with high reputation scores execute tasks first, and nodes with low reputation scores can be kicked out, so the embodiments of the present application can be widely reused in the industry.

[0174] Step S204, obtaining a second transaction to be uploaded to the chain from the transaction pool; the second transaction to be uploaded to the chain includes a contract identifier.

[0175] Specifically, the off-chain device (ie, the business device) may send the second transaction to be on-chain to the blockchain node. Assuming that the second transaction to be on-chain is a resource transfer transaction, the second transaction to be on-chain includes a contract identifier for indicating the transfer contract.

[0176] Step S205, if the contract identifier is the identifier of a smart contract, the second transaction to be on-chain is sent to the scheduling component, so that the scheduling component allocates a second working node for the second transaction to be on-chain among A working nodes according to the transaction execution resources corresponding to the second transaction to be on-chain and the node idle resources corresponding to the first working node; the second working node is used to execute the second transaction to be on-chain according to the smart contract in the second execution component; the second execution component refers to the execution component running on the second working node.

[0177] Specifically, assuming that the smart contract described in steps S201 and S202 above is a transfer contract, through steps S201 and S202, a contract service of the transfer contract can be constructed in the cluster resource management system.

[0178] If the contract identifier is the identifier of the transfer contract, the block node can send the second transaction to be on-chain to the scheduling component in the contract service. It can be understood that the scheduling component has started the first working node to run the first execution component, so according to the transaction execution resources corresponding to the second transaction to be on-chain and the node idle resources corresponding to the first working node, the scheduling component can allocate the second working node for the second transaction to be on-chain from A working nodes. For the specific implementation process of this process, please refer to the following Fig.10 The description in the corresponding embodiment will not be elaborated here.

[0179] Step S206: If the second transaction execution result generated by the second working node after executing the second transaction to be on-chain is obtained, a second block to be agreed upon is generated according to the second transaction to be on-chain and the second transaction execution result.

[0180] From the above, it can be seen that the embodiment of the present application can create a contract service for the smart contract in the cluster resource management system, and then the execution task corresponding to the first transaction to be on the chain can be transferred from the block producing node to the contract service, that is, the first transaction to be on the chain is executed by the first working node running the first execution component. Therefore, by adopting the present application, the resource utilization rate of all blockchain nodes can be improved, and then the efficiency of transaction on the chain can be improved.

[0181] For further information, see Figure 7 , Figure 7 This is a flow diagram of a data processing method provided in an embodiment of the present application. Figure 3 The implementation process of the data processing method can be performed in the block node, the master node, the scheduling node, or interactively in the block node, the master node, and the scheduling node, which is not limited here. Figure 1 Any blockchain node in the blockchain node cluster of the corresponding embodiment. Figure 7The present application embodiment is described using the master node as an example. Figure 7 As shown, the data processing method may at least include the following steps S301-S302.

[0182] Step S301, obtaining the encoded file sent by the block-producing node in the blockchain; the encoded file is generated by the block-producing node when the transaction to be on-chain is a transaction for installing a smart contract, by encoding the transaction to be on-chain.

[0183] For the specific implementation process of step S301, please refer to the above Figure 2 The description of step S101 - step S102 in the corresponding embodiment is not repeated here.

[0184] Step S302, according to the encoding file, create a contract service for the smart contract in the cluster resource management system; the contract service includes a scheduling component and A execution components running on A working nodes; A is a positive integer; wherein one working node is used to run one execution component; the master node and the A working nodes different from the master node all belong to the blockchain nodes in the blockchain; the scheduling component is used to allocate a working node z to the transaction to be chained in the A working nodes when obtaining the transaction to be chained sent by the block-producing node; the working node z is used to execute the transaction to be chained in the execution component x; the execution component x refers to the execution component running on the working node z.

[0185] Specifically, the total number of blockchain nodes in the blockchain other than the master node is D; D is a positive integer greater than 1; the node idle resources sent by the D blockchain nodes are obtained, and the reputation values ​​corresponding to the D blockchain nodes are obtained; the D blockchain nodes include blockchain node B c , c is a positive integer, and c is less than or equal to D; for blockchain node B c The node idle resources and blockchain node B c The reputation value of blockchain node B is weighted and summed up to get c Corresponding allocation values; according to the allocation values ​​corresponding to the D blockchain nodes, A working nodes are determined among the D blockchain nodes.

[0186] Please also see Figure 8 , Figure 8 This is a blockchain shared computing system architecture based on Apache Mesos provided by the embodiment of the present application. Figure 8 As shown in Figure 1, the Apache Mesos-based blockchain shared computing system architecture specifically describes the internal implementation of the service and the interaction between various modules. The Framework (i.e., the contract service for smart contract 1) is described in detail as follows:

[0187] 1. Scheduler: It is used to manage and schedule tasks in the Mesos cluster. It is responsible for communicating with the master node, receiving resource slices, managing task queues, assigning tasks, detecting task status, and implementing custom scheduling strategies.

[0188] a) Resource allocation, receiving and allocating resource slices;

[0189] b) Elastic expansion: elastically expand the number of executors of contract services according to the idle computing resources of blockchain nodes;

[0190] 2. Executor cluster: A contract service may have multiple executors for calculation. Multiple executors form an execution component cluster to jointly support the calculation of the contract service.

[0191] a) Executor instance, executing contract tasks

[0192] i. Contract main project, smart contract code written by business objects;

[0193] ii. Contract Software Development Kit (SDK), the SDK called by the smart contract;

[0194] iii. Log module, the module for printing contract logs;

[0195] 3. Monitoring module, which monitors the central processing unit (CPU), memory, storage and other resources of the contract Executor;

[0196] a) Indicator collection, responsible for regularly collecting various indicators of the contract Executor;

[0197] b) Monitoring and display: display the collected indicators.

[0198] The embodiments of the present application are mainly used to share the contract computing resources of the blockchain among multiple blockchain nodes, make full use of the computing resources of each blockchain node, and reuse or kick out the blockchain node in the blockchain network according to the reputation of the blockchain node.

[0199] It can be understood that the allocation values ​​corresponding to the D blockchain nodes are sorted in order from large to small, that is, the allocation values ​​with large values ​​are arranged in the front order, and the allocation values ​​with small values ​​are arranged in the back order. Further, according to the sorted D allocation values, the master node determines A working nodes among the D blockchain nodes, specifically obtaining the A working nodes with the allocation values ​​in the front order, that is, the allocation values ​​corresponding to the A working nodes are the first A among the sorted D allocation values.

[0200] The above process enables blockchain contract services to be executed on multiple blockchain nodes (i.e., A working nodes), so computing resources can be shared. Fine-grained resource management can be achieved through the resource slice mechanism of Mesos, so the degree of participation of blockchain nodes can be controlled according to credibility.

[0201] From the above, it can be seen that the embodiment of the present application can create a contract service for the smart contract in the cluster resource management system, and then the execution task corresponding to the first transaction to be on the chain can be transferred from the block producing node to the contract service, that is, the first transaction to be on the chain is executed by the first working node running the first execution component. Therefore, by adopting the present application, the resource utilization rate of all blockchain nodes can be improved, and then the efficiency of transaction on the chain can be improved.

[0202] For further information, see Fig. 9 , Fig. 9 This is a flow diagram of a data processing method provided in an embodiment of the present application. Figure 4 The implementation process of the data processing method can be performed in the block node, the master node, the scheduling node, or interactively in the block node, the master node, and the scheduling node, which is not limited here. Figure 1 Any blockchain node in the blockchain node cluster of the corresponding embodiment. Fig. 9 The present application embodiment is described by taking a scheduling node as an example. Fig. 9 As shown, the data processing method may at least include the following steps S401 to S403.

[0203] Step S401, through the scheduling component, obtain the first transaction to be on-chain sent by the block-producing node in the blockchain; the contract service is created by the master node in the cluster resource management system according to the first transaction to be on-chain.

[0204] For the specific implementation process of step S401, please refer to the above Figure 2 The description of steps S101 to S103 in the corresponding embodiment will not be repeated here.

[0205] Step S402: Determine a first working node among A working nodes according to the first transaction to be on-chain; the A working nodes are respectively used to run A execution components in the contract service; wherein one working node is used to run one execution component.

[0206] Specifically, obtain the node idle resources corresponding to A working nodes and the reputation values ​​corresponding to A working nodes; A working nodes include working nodes E f, f is a positive integer, and f is less than or equal to A; for working node E f The idle resources of nodes and working nodes E f The reputation values ​​of the working node E are weighted and summed to obtain f Corresponding allocation value; among the allocation values ​​corresponding to the A working nodes respectively, obtain the maximum allocation value, and among the A working nodes, determine the working node corresponding to the maximum allocation value as the first working node.

[0207] Step S403, according to the first transaction to be on-chain, start the first execution component in the first working node, so that the first working node executes the first transaction to be on-chain in the first execution component; the first execution component refers to the execution component running on the first working node.

[0208] For the specific implementation process of step S403, please refer to the above Figure 2 The description of step S103 in the corresponding embodiment is not repeated here.

[0209] From the above, it can be seen that the embodiment of the present application can create a contract service for the smart contract in the cluster resource management system, and then the execution task corresponding to the first transaction to be on the chain can be transferred from the block producing node to the contract service, that is, the first transaction to be on the chain is executed by the first working node running the first execution component. Therefore, by adopting the present application, the resource utilization rate of all blockchain nodes can be improved, and then the efficiency of transaction on the chain can be improved.

[0210] For further information, see Fig.10 , Fig.10 This is a flow diagram of a data processing method provided in an embodiment of the present application. Figure 5 The implementation process of the data processing method can be performed in the block node, the master node, the scheduling node, or interactively in the block node, the master node, and the scheduling node, which is not limited here. Figure 1 Any blockchain node in the blockchain node cluster of the corresponding embodiment. Fig.10 The embodiment of the present application is described by taking a block-producing node as an example. Fig.10 As shown, the data processing method may at least include the following steps S501 to S506.

[0211] Step S501, through the scheduling component, obtain the first transaction to be on-chain sent by the block-producing node in the blockchain; the contract service is created by the master node in the cluster resource management system according to the first transaction to be on-chain.

[0212] Step S502: Determine a first working node among A working nodes according to the first transaction to be on-chain; the A working nodes are respectively used to run A execution components in the contract service; wherein one working node is used to run one execution component.

[0213] Step S503, according to the first transaction to be on-chain, start the first execution component in the first working node, so that the first working node executes the first transaction to be on-chain in the first execution component; the first execution component refers to the execution component running on the first working node.

[0214] For the specific implementation process of steps S501 to S503, please refer to the above Fig. 9 The description of steps S401 to S403 in the corresponding embodiment will not be repeated here.

[0215] Step S504: Obtain the second transaction to be uploaded to the chain sent by the block producing node through the scheduling component.

[0216] Specifically, Mesos's two-layer scheduling architecture and fine-grained resource management enable it to have stronger optimization capabilities in resource allocation and utilization, especially when dealing with large data centers and complex task scenarios, Mesos may have higher resource utilization. Therefore, this application proposes a blockchain shared computing solution based on Apache Mesos, which focuses on solving the above problems. The embodiment of this application automatically schedules the contract computing task to the appropriate blockchain node for execution through the resource allocation algorithm of the Mesos Framework, without the need to execute it on only one blockchain node.

[0217] Step S505: Determine the second working node from the A working nodes according to the transaction execution resources corresponding to the second transaction to be on-chain and the node idle resources corresponding to the first working node.

[0218] Specifically, the transaction execution resources corresponding to the second transaction to be on the chain are compared with the node idle resources corresponding to the first working node; if the transaction execution resources corresponding to the second transaction to be on the chain are less than or equal to the node idle resources corresponding to the first working node, the first working node is determined as the second working node; if the transaction execution resources corresponding to the second transaction to be on the chain are greater than the node idle resources corresponding to the first working node, the resource difference between the transaction execution resources corresponding to the second transaction to be on the chain and the node idle resources corresponding to the first working node is determined; if the node idle resources corresponding to the third working node among A working nodes are equal to or greater than the resource difference, the first working node and the third working node are determined as the second working node; the third working node refers to a working node among the A working nodes except the first working node.

[0219] This step may also include: if the node idle resources corresponding to the remaining working nodes among A working nodes except the first working node are less than the resource difference, a resource reallocation request is generated according to the second resource to be on the chain; the resource reallocation request is sent to the master node, so that the master node reallocates G working nodes for the contract service in the cluster resource management system according to the resource reallocation request; G is a positive integer; the node idle resources corresponding to the G working nodes are equal to or greater than the transaction execution resources corresponding to the second transaction to be on the chain.

[0220] Since the number of tasks for different contracts may be different, at a certain point in time, the number of tasks for some contracts will be relatively high. At this time, the contract requires more Executors to support its calculation. The embodiment of the present application is based on the elastic expansion algorithm of the Mesos Framework to perform dynamic changes in the number of Executors.

[0221] Step S506, according to the second transaction to be on-chain, start the second execution component in the second working node, so that the second working node executes the second transaction to be on-chain in the second execution component; the second execution component refers to the execution component running on the second working node.

[0222] Specifically, the application structure is as follows:

[0223] 1. This paper describes the system architecture of the blockchain shared computing solution based on Apache Mesos, including the Scheduler, Executor cluster and monitoring module of the cross-node contract virtual machine service. The above system architecture is the operating basis of the entire environment. The above solution and system architecture ensure the efficient and stable operation of the system.

[0224] 2. Designed the full life cycle process of the blockchain shared computing solution based on Apache Mesos, including the contract installation process based on Apache Mesos (the business object writes the smart contract and compiles it into binary and other contract files and sends them to the blockchain node, the blockchain node is packaged into an image, the Framework and Executor are started in Apache Mesos, and then the contract initialization method is executed), the contract transaction execution process based on Apache Mesos (the blockchain node sends the transaction to the Apache Mesos Master to execute the task), and the intelligent scheduling strategy based on the reputation of the blockchain node (the reputation score is revised based on the results of the transaction execution of each blockchain node, and resources are allocated or the blockchain node is punished according to the reputation score).

[0225] From the above, it can be seen that the embodiment of the present application can create a contract service for the smart contract in the cluster resource management system, and then the execution task corresponding to the first transaction to be on the chain can be transferred from the block producing node to the contract service, that is, the first transaction to be on the chain is executed by the first working node running the first execution component. Therefore, by adopting the present application, the resource utilization rate of all blockchain nodes can be improved, and then the efficiency of transaction on the chain can be improved.
