Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to be limiting of the invention.

Before further detailed description of the embodiments of the present invention, terms and expressions mentioned in the embodiments of the present invention are explained, and the terms and expressions mentioned in the embodiments of the present invention are applied to the following explanations.

1) A Block (Block) recording a data structure of the ledger data updated by the exchange within a period of time, marked with a timestamp and a unique mark (e.g. a digital fingerprint) of a previous Block, and after the Block is subjected to consensus verification by nodes in the Block chain network, the Block is appended to the end of the Block chain to become a new Block.

2) A chain of blocks (Blockchain), a chain of data structures in which blocks are assembled in a sequentially contiguous manner, in each block referencing a hash value of a previous block or a subset thereof, thereby cryptographically securing the recorded transaction as being non-tamperable and non-forgeable.

3) The account book (Legger) is the sum of data recorded by taking an account as a dimension in a block chain network, and comprises the elements of the account book data, the state of the account book, the state certification of the account book, a block index and the like.

4) Consensus (Consensus), a process in a blockchain network, is used to agree on transaction results among multiple nodes involved, and the mechanisms for achieving Consensus include Proof of workload (PoW), Proof of rights and interests (PoS, Proof of stamp), Proof of equity authority (DPoS), Proof of Elapsed Time (PoET, Proof of Elapsed Time), and so on.

5) Intelligent Contracts (Smart Contracts), also known as chain codes (chainodes), trigger execution of programs deployed in blockchain networks according to conditions, run in a secure container to initialize and manage ledger data and ledger states.

An exemplary functional architecture of a block chain network for implementing the embodiment of the present invention is described below, and referring to fig. 1, fig. 1 is a schematic functional architecture diagram of a block chain network provided in the embodiment of the present invention, which includes an application layer 101, a consensus layer 102, a network layer 103, a data layer 104, and a resource layer 105, which are described below respectively.

The resource layer 105 encapsulates various available computing and storage resources, such as those in computers, servers/clusters, and clouds, abstracts and provides a uniform interface to the data layer 104 to mask the variability of the underlying hardware implementing the resource layer 105.

The computing resources include various forms of processors such as a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), and a Field-Programmable Gate Array (FPGA).

The storage resources include various types of storage media such as various volatile memories and nonvolatile memories. The nonvolatile Memory may be a Read Only Memory (ROM) or a Programmable Read-Only Memory (PROM). Volatile Memory can be Random Access Memory (RAM), which acts as external cache Memory.

The computing resources and storage resources of the resource layer 105 may be mapped to various types of nodes in a blockchain network, and the storage medium implementing an embodiment of the present invention stores executable instructions for implementing the blockchain network deployment method of an embodiment of the present invention, and once the executable instructions deployed to the nodes are executed, the underlying resources (e.g., various types of processors) implementing the nodes will implement the deployment of various types of nodes in the blockchain network and perform the functions of the various types of nodes, thereby implementing ledgers for transactions in business processes and various applications based on the ledgers.

By way of example, executable instructions may be written in any form of programming language, including compiled or interpreted languages, or declarative or procedural languages, in the form of software (including system programs and applications), software modules, scripts, plug-ins, and the like, and may be deployed in any form, including as a stand-alone program or as a module, component, or other unit suitable for use in a computing environment.

Network layer 103 encapsulates point-to-point (P2P) network protocols, data propagation and verification mechanisms, access and authentication mechanisms, and service agent identities. The P2P network protocol realizes communication among nodes in the blockchain network, a data propagation mechanism ensures the propagation of transaction/transaction results in the blockchain network, and a data verification mechanism is used for realizing the reliability of data transmission among the nodes based on an encryption method (such as a digital certificate, a digital signature and a public/private key pair); the access and authentication mechanism is used for managing the access and authentication of the terminal based on the identity of the service subject.

The consensus layer 102 encapsulates mechanisms for achieving consistency of transaction results propagated in the block chain, including POS, POW, DPOS, etc., and supports pluggable consensus mechanisms.

The application layer 101 encapsulates various services that the blockchain network can implement, including transaction settlement, tracing, and evidence storage.

Referring to fig. 2, it is a schematic structural diagram of a resource layer constructed as a container cluster 200 by deploying a containerization management system, where two types of nodes, namely a management Node (Master Server)200 and a service Node 300(Node), are formed by deploying corresponding components of the containerization management system in a machine providing resources to the resource layer, the management Node is used to manage scheduling and running of containers in the service Node, the service Node is mainly used to run various containers, and provide an isolated running environment for various applications in a block chain network, for example, a chain code container for running a chain code, a Node container for running a code of a Node (i.e., a code of various types of nodes in the block chain network), and the following description is separately given.

The management node (Master Server)200 is responsible for managing the cluster, providing access to the cluster's resource data externally in the form of a Service (Service), and includes several exemplary components.

1) A state component (etcd) for saving the state of the entire cluster.

2) An application program interface service (API Server) component for providing a unique entry for resource operations and providing mechanisms for authentication, authorization, access control, API registration and discovery, and the like.

3) And the scheduling (Scheduler) component is used for being responsible for scheduling the resources and scheduling the containers to the appropriate nodes to run according to a preset scheduling strategy. For an application of a blockchain network, the container group (Pod) of the same group of resources in a shared machine (that is, a machine on which a service node component is deployed) in a container run by a service node is a minimum unit of invocation, and can be implemented by one or more container groups, where the resources shared by the containers in the container group include: application namespace, network namespace, hostname, and storage Volume (Volume).

Taking the shared storage volume as an example, when a shared File System component is deployed on a node, such as a Network File System (NFS), a cluster File System (GlusterFS), or a ceph File System (Cephfs), the scheduling component can easily schedule (mount) a container group mounted on the storage volume to a storage volume of another machine (node).

4) And the control management (Controller Manager) component is used for monitoring/maintaining the state of the cluster, monitoring the current state of each resource object of the whole cluster in real time through an interface provided by the application program interface service component, and restoring the current state to the expected state when the system state changes due to various faults.

5) A copy Controller (RC) component for controlling the running of a certain number of Pod copies in a certain time; for example, if the running Pod copy exceeds the set value, closing part of Pod copies; if the Pod copy is less than the set value, a new Pod copy is created.

6) And the Deployment Controller (Deployment Controller) component is used for managing and maintaining a resource object-Deployment (Deployment) object in the container cluster finding, associating the Deployment object with the replica Controller, and providing declarative updates for the container group and the replica Controller in the Deployment object, so as to declare the target states of the container group and the replica Controller, and thus when the Deployment object is updated, the replication Controller and the container group are controlled to be updated.

Service node 300 includes the following exemplary components.

1) And the container engine (noted as Docker) is used for taking charge of all specific image downloading and container operation.

2) The daemon component (denoted as Kubelet) is responsible for maintaining the life cycle of the container (creation, start and stop), and also for the management of the storage volume and the Container Network Interface (CNI).

Taking management of a storage volume as an example, a daemon component mounts each container in a container group to the same storage volume through a component of a shared File System deployed in a node, such as a Network File System (NFS), a cluster File System (GlusterFS), and a ceph File System (Cephfs), so that each container uses the same storage volume to store data produced in the operation process, and the data in the storage volume can be accessed by any container in the same container group.

3) And the load balancing component (denoted as Proxy) is responsible for providing Service with Service discovery and load balancing inside the cluster.

Based on the cluster shown in fig. 2, an exemplary process in which an image of an application deploying one blockchain network is encapsulated into a container group (referred to as a target Pod in the following example) and runs on a Node (referred to as a target Node in the following example) is as follows.

First, the management tool (Kubectl) of the container cluster 200 submits a request for creating a copy Controller (RC), which includes the definition of the target Pod; the number of copies that the target Pod needs to run; target Pod label (label) to be monitored, and the like.

Then, the request is written into the etcd through the API Server, and at this time, the Controller Manager monitors the RC event through the interface of the API Server for monitoring resource change, finds that there is no Pod instance corresponding to the RC in the current cluster, generates a Pod object according to the Pod template definition in the RC, and writes into the etcd through the API Server.

Immediately after the RC event is discovered by the Scheduler, it immediately executes a scheduling procedure: and selecting a Node of the drop for the new Pod, writing the result into the etcd through the API Server, monitoring the new Pod through the API Server by a Kubelet process running on the target Node, and starting the new Pod according to the definition of the new Pod until the life of the Pod is finished.

Subsequently, Kubectl submits a new Service creation request mapped to the target Pod, Controller Manager queries the associated Pod instance through Label, then generates endpoint (Endpoints) information (including addresses and ports) of Service, and writes the endpoint information into etcd through API Server; and Proxy processes running on all nodes in the container cluster inquire through an API (application program interface) Server, monitor the Service object and the corresponding endpoint information, and establish a load balancer in a software mode to realize the flow forwarding function from the Service access to the backend Pod.

In combination with the above, the blockchain network service platform implementing the embodiment of the present invention is implemented by deploying a container cluster in a resource layer and running a container encapsulated with a blockchain network application, and thus, the blockchain network implementing the embodiment of the present invention may be provided in the form of a memory and a processor, where executable instructions are stored in the memory, and when the executable instructions are executed by the processor, the container cluster is established on a plurality of nodes running the processor and the memory, and the chain code installation method in the blockchain network service platform implementing the embodiment of the present invention is implemented by running the encapsulated application in the container.

Referring to fig. 5, for one exemplary architecture of a blockchain network deployed using a blockchain network services platform, an application obtains a legitimate identity certificate from a CA to join an application channel within the network. Before the formal transaction is initiated, a transaction Proposal (promosal) needs to be constructed and submitted to endorsement nodes in the organization 1 and the organization 2 for endorsement; after the client collects enough endorsement support (the number is determined according to the endorsement policy), a legal transaction request (endorsement carrying endorsement nodes) can be constructed by using the endorsement, and the legal transaction request is sent to a sequencing node (order) in the sequencing service for sequencing so as to package transactions to form a block.

Referring to fig. 6, a transaction flow of an application and a blockchain network is shown, where functions of a client and each node in the transaction flow are as follows:

client (application): the SDK is used to interact with the blockchain network. First, the client obtains a legitimate identity certificate from the CA to join the application channel within the network. Before the formal transaction is initiated, a transaction Proposal (promosal) needs to be constructed and submitted to an endorsement node for endorsement; after the client collects enough endorsement support (the number is determined according to the endorsement policy), a legal transaction request (endorsement carrying endorsement nodes) can be constructed by using the endorsement, and the legal transaction request is sent to a sequencing node (Orderer) for sequencing so as to package transactions to form a block. The client can also monitor messages in the network through an event mechanism to know whether the transaction is successfully received.

Endorsement node (Endorser): the method is mainly provided for the client to call and complete endorsement (signature) processing of a transaction proposal. After receiving a transaction proposal from a client, firstly, checking the validity and ACL authority, simulating the operation transaction (the chain code name and parameters required to be executed can be executed in the transaction, the transaction is executed, and the chain code specified in the transaction is executed essentially), endorsing (namely, digitally signing) the state change caused by the transaction (recorded in a read-write set form, including a read state key and a read state version, and a written state key value) and returning the result whether the client supports the transaction or not.

Sort node (Orderer): and receiving the transaction containing the endorsement signature, sequencing the unpacked transactions to generate a block, and broadcasting the block to the Peer node.

Master node (Leader Peer): and a node in communication with the sequencing node, responsible for obtaining the latest tiles from the sequencing node and synchronizing internally in the blockchain network.

Accounting node (commit): the structure of the block chain and the ledger (including the status DB, history DB, index DB, etc.) is maintained. The node periodically obtains the sorted batch transaction block structure from the sorting node and checks the transactions (including transaction message structure, signature integrity, whether duplication occurs, whether the read-write set versions match, etc.). And executing legal transaction after the check is passed, writing the result into an account book, and constructing a new block.

It should be noted that all Peer nodes are accounting nodes and are responsible for verifying transactions in the block of the sequencing node and maintaining state data and copies of the account book. Some Peer nodes will perform transactions and sign endorsements to the results, acting as endorsement nodes. The endorsement node is a dynamic role and is bound with a specific chain code. Each chain code in the chain code container sets an endorsement policy when being instantiated, and specifies which nodes are valid after the transaction endorsement. And the endorsement node is only when the application program initiates a transaction endorsement request to the endorsement node, and is a common accounting node at other times, and the endorsement node is only responsible for verifying the transaction and accounting.
