Background
The Block chain (blockchain) technology is a brand new distributed infrastructure and computing method in the technological financial neighborhood. In the blockchain technology, blockchains can be classified into public chains, private chains and alliance chains according to the differences of blockchain network access control rights. Wherein, the nodes of the public chain are a block chain structure which can be participated by any person and can be accessed by any person; private links are blockchain structures that are open only to individual individuals (e.g., companies, schools inside); the alliance chain is a block chain structure which is widely applied at present and is very common. In this structure, the blockchain is maintained by certain organizations, is open to certain individuals, and can introduce supervisory nodes, so that the blockchain can meet corresponding supervisory requirements while being non-tamperable.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
A blockchain is a chain of blocks that each record a hash value of a previous block in addition to the data of the block. The block chain has two core concepts, one is a cryptography technology, the other is a decentralization concept, and the history information on the block chain cannot be tampered based on the two concepts. However, in the federation chain, node information in all organizations is generated for a single organization, and the requirement of the decentralization idea cannot be met.
In order to solve the above problems, the embodiment of the invention provides a method for constructing a blockchain. One possible system architecture to which the method may be applied, as shown in FIG. 1, includes an organization and nodes.
The mechanism is a main body admitted by the alliance chain committee and is provided with a mechanism certificate authority and a mechanism private key authority. The organization may generate an in-organization node. The organization may issue a node certificate node. Crt for the node to which it belongs and generate a node private key. The certificate is a series of numbers for marking the identity information of each party in the communication of the Internet, and provides a way for verifying the identity of a communication entity on the Internet, wherein the digital certificate is not a digital identity card, but a seal or a stamp (or a signature added on the digital identity card) covered on the digital identity card by an identity authentication mechanism. It is issued by an authority-CA-authority, also known as a certificate authority (Certificate Authority) center, which people can use to identify the identity of each other on the internet.
In a blockchain peer-to-peer network, nodes participate in network construction and data exchange. A node refers to a participant with a unique identity that has a complete ledger copy with the ability to participate in blockchain peer-to-peer network consensus and ledger maintenance. In the embodiment of the invention, the nodes in the institutions are nodes running in the alliance chains, belong to corresponding institutions, and possibly are in one or more groups. The node has a node certificate node. Crt and a node private key node. The nodes in the organization are linked with other nodes of the group to which the nodes belong in the organization and maintain the group. Data isolation among groups, each group independently running a respective consensus algorithm, different groups may use different consensus algorithms.
The embodiment of the invention supports a multi-group architecture, the network is shared among groups, and the isolation of network messages among the account books is realized through a network access module. All organizations negotiate to finish the alliance chain root certificate, and all organizations have node certificate node. Crt and node private key node. Key of the nodes in the corresponding organizations respectively. Inter-chassis status peering, intra-chassis nodes only communicate with other nodes of the belonging group. The inter-agency nodes may negotiate credentials with each other and create a new group. One mechanism can correspond to one in-mechanism node, or can correspond to a plurality of in-mechanism nodes; the nodes in the same organization corresponding to the same organization can belong to the same group or can belong to different groups.
Based on the above architecture, the embodiment of the present invention provides a method for constructing a blockchain, as shown in fig. 2, where the method for constructing a blockchain provided by the embodiment of the present invention includes the following steps:
In the embodiment of the invention, a first organization generates a first certificate of a node in the first organization, the first organization broadcasts the generated first certificate to a second organization and receives a second certificate of the node in the second organization, wherein the first organization is any organization in a alliance chain, the node in the first organization is any node in the nodes to which the first organization belongs, and the second organization is an organization except the first organization in the alliance chain. And the first organization verifies the received second certificate, generates a configuration file of the alliance chain according to the first certificate and the second certificate after the second certificate passes the verification, and sends the first certificate, the first private key of the first organization internal node and the configuration file to the first organization internal node so as to enable the first organization internal node to be started. In the embodiment of the invention, only the certificates are required to be broadcast among the institutions, and the private keys of the nodes are generated and maintained by the institutions, so that the private keys of the nodes in the institutions cannot go out of the intranet of the institutions, and the security of the nodes among the institutions is ensured. Meanwhile, the organizations of the alliance chain respectively generate the certificates and the private keys of the corresponding nodes, instead of generating the certificates and the private keys of other organizations by one organization, so that the peer-to-peer relationship among the organizations is ensured.
Specifically, in the federation chain of the embodiment of the invention, each organization generates node certificates for nodes in the corresponding organization, and a plurality of organizations broadcast the node certificates by adopting a peer-to-peer negotiation method and perform certificate verification. The organization can generate configuration files when the alliance chain node is started according to the certificates of all the nodes, and the node private key is stored locally in the organization and is not sent to other organizations, so that the node private key cannot be revealed, and the security of the private key is ensured. Since the generated configuration files do not contain node private keys, even if the generated configuration files are revealed, these configuration files cannot be used by non-local institutions.
The node certificate can be actively sent to other institutions in the alliance chain, namely the second institution, by the first institution; or may be obtained from the first mechanism by the second mechanism. After each organization receives the node certificates broadcast by other organizations, the information such as the issuer, the user, the validity period, the key usage, the public key contained in the certificates and the like of the certificates is verified, so that whether the node certificates are legal or not is judged. If the node certificates are legal, the node certificate negotiation is successful, and the subsequent flow is continuously executed; if there is an illegal certificate, node certificate negotiation fails.
After the node certificate negotiation is successful, each organization in the alliance chain generates a configuration file of the corresponding node in the organization, and sends the configuration file of the node in each organization, the certificate and the private key of the node in the organization to the node in the organization so as to enable the node in the organization to be started. After the first organization sends the first certificate, the first private key of the node in the first organization and the configuration file to the node in the first organization, the method further comprises:
the first in-mechanism node verifies the first certificate by using the first private key, and after verification is passed, the first in-mechanism node is started;
after the first intra-mechanism node is started, the method further comprises the following steps:
the first in-mechanism node sends a first heartbeat request to the second in-mechanism node according to the configuration file, and receives a second heartbeat request of the second in-mechanism node;
and after the first intra-institution node determines that the number of the received second heartbeat requests is greater than a first threshold value, generating an originating block of the alliance chain.
In the specific implementation process, each mechanism configures the private key of the node to an installation package of the node in the corresponding mechanism, and the node is started. At present, two configuration modes are supported, namely a key type private key encryption mode and a mode of directly loading a private key into a node folder. After the first in-mechanism node receives the first certificate, the first private key and the configuration file sent by the mechanism, the first in-mechanism node verifies the first certificate by using the first private key, judges whether the first private key is matched with the first certificate, and after the verification is passed, the first in-mechanism node starts, otherwise, the initialization process of the alliance chain is ended. After the first intra-organization node is started, a first heartbeat request is sent to other nodes in the alliance chain, namely the second intra-organization node according to the received configuration file. Nodes within the first organization will only have a consensus, i.e., co-create a blockchain, of collecting heartbeat requests from a sufficient number of other nodes. In this way, the success rate of blockchain creation is guaranteed. The consensus algorithm is that each node in the blockchain peer-to-peer network confirms a batch of transactions through an algorithm and ensures that all nodes have consistent confirmation results on the batch of data.
For example, if the number of negotiated node certificates is n, i.e. the number of nodes in the organization is n, and the operations of certificate negotiation, node deployment, etc. have been completed. After each node in the alliance chain is started, the nodes are connected with other nodes in the alliance chain according to the configuration file of the alliance chain. The first thresholds in the different consensus methods are different. If the node in the organization can only generate the created blocks of the alliance chain after collecting the heartbeat requests with the number more than 2n/3 (rounding upwards) in the PBFT (Practical Byzantine Fault Tolerance) mode, the Bayesian fault-tolerant algorithm is applied, and the consensus is further completed. In the RAFT (a distributed consistency algorithm) mode, only after heartbeat requests with the number greater than n/2 (rounded up) are collected, the alliance chain groups can be identified together, and deployment is completed. To guarantee federation chain consensus efficiency, the number of node certificates n in PBFT is not recommended to exceed 40, and the number of node certificates n in raft is not recommended to exceed 100.
Further, the first organization generates a configuration file of a federation chain according to the first certificate and the second certificate, including:
the first organization analyzes public key information and certificate fingerprints contained in the first certificate and the second certificate to generate the configuration file, wherein the configuration file contains network connection addresses of N second nodes.
The first intra-mechanism node sends a first heartbeat request to the N second nodes according to the configuration file, and the first heartbeat request comprises:
and the first intra-mechanism node sends the first heartbeat request to the N second nodes according to the network connection addresses of the N second nodes.
In the implementation process, the first organization generates a configuration file according to all node certificates in the alliance chain. Specifically, public key information and certificate fingerprints contained in a certificate are analyzed to generate serial numbers of a alliance chain, and when a subsequent node generates an originating block, the serial number information is placed into the originating block. Meanwhile, the first mechanism generates configuration files such as group capacity, network connection address and the like required by the start of the block chain. Thus, when the node in the first mechanism needs to send the first heartbeat request, the first heartbeat request can be sent to the second nodes according to the network connection address of each second node.
After the alliance chain is initialized, different groups are needed to be divided among the institutions according to different services. Each group contains a plurality of nodes, and the nodes belonging to the same organization can belong to different groups or belong to the same group.
After the first intra-institution node determines that the number of the received second heartbeat requests is greater than a threshold, generating an originating block of the alliance chain further includes:
The first organization determines a third certificate from the first certificate and the N second certificates, wherein the third certificate is a certificate corresponding to a third node belonging to a group, and the first organization comprises a first organization node belonging to the group;
the first mechanism generates a group configuration item according to the third certificate, wherein the group configuration item is used for indicating node information of the third node;
the first mechanism generates a group configuration file of the group according to the third certificate and the group configuration item;
the first organization sends the group configuration file to the first organization nodes belonging to the group;
and restarting the first intra-mechanism nodes belonging to the group according to the group configuration file so as to enable the first intra-mechanism nodes to have group attributes.
Specifically, the group is divided after the alliance chain is initialized, and since all node certificates in the alliance chain are obtained by each organization, the processes of obtaining the node certificates and verifying do not need to be executed again, and since the first organization comprises the first intra-organization nodes belonging to the group, the first organization can directly determine the third certificate corresponding to the third node belonging to the group from all the node certificates. Generating a group configuration item according to the third certificate. The group configuration item may include data such as a certificate of each node in the group, an IP of the node, a port number, and the like, and may indicate which nodes are specifically the third node in the group. The first organization analyzes public key information and certificate fingerprints contained in the certificates according to the group configuration items and the node certificates in the group, and generates a group serial number when the group is started. When the subsequent node generates the group creation block, the group serial number information is put into the group creation block. Meanwhile, the first mechanism generates configuration files such as group capacity required in dividing the group and network connection addresses of nodes in the group. After each organization generates a group configuration file, the group configuration file is sent to the nodes in the organization belonging to the group, and after the group configuration file is imported into the node installation package, the nodes are restarted. Thus, the nodes in the organization belonging to the group have group attributes after restarting according to the group configuration file.
Similar to the initialization of the federation chain, after the first intra-organization node belonging to the group is restarted according to the group configuration file, the method further includes:
the first intra-mechanism node belonging to the group sends a third heartbeat request to a third node except the first intra-mechanism node according to the group configuration file, and receives a fourth heartbeat request;
and after the nodes in the first mechanism belonging to the group determine that the number of the received fourth heartbeat requests is larger than a second threshold value, generating a group generation block of the group.
That is, nodes in the first organization only have a common knowledge of the heartbeat requests collected by a sufficient number of other nodes in the group, i.e., create a group creative block. In this way, the success rate of group division is ensured.
Further, in the embodiment of the invention, the node also has a detection function. Specifically, when the node is started, a corresponding node certificate is generated, and the node configuration item contains information such as node IP, port number, group to which the node belongs, and the like, so that the availability of the generated node is ensured.
Furthermore, the embodiment of the invention also designs a monitoring function. Corresponding monitoring services can be configured, such as reporting monitoring results to user WeChat by default configuration. According to the embodiment of the invention, the RPC (Remote Procedure Call ) request can be initiated to the nodes in the mechanism through the mechanism to obtain the related parameters when the nodes in the mechanism run, meanwhile, the nodes in the mechanism are monitored through analyzing log information when the nodes in the mechanism run, and the monitoring result is reported to the service configured by the user. For example, a monitoring service is configured by default, reporting to WeChat, personal website, dedicated service settings are supported, and reporting to enterprise WeChat, etc.
In addition, the embodiment of the invention also provides a group division method of the alliance chain, which is used for carrying out peer-to-peer group division in the alliance chain initialized in any mode. The group division method of the alliance chain in the embodiment of the invention comprises the following steps:
the first organization determines a third certificate from all certificates of the alliance chain, wherein the third certificate is a certificate corresponding to a third node belonging to the group; the first organization is any organization in the federation chain that includes nodes within the first organization that belong to the group.
The first mechanism generates a group configuration item according to the third certificate, wherein the group configuration item is used for indicating node information of the third node.
The first mechanism generates a group configuration file of the group according to the group configuration item and the third certificate.
The first organization sends the group profile to the first in-organization nodes belonging to the group.
And restarting the first intra-mechanism nodes belonging to the group according to the group configuration file so as to enable the first intra-mechanism nodes to have group attributes.
And the first intra-mechanism node belonging to the group sends a third heartbeat request to a third node except the first intra-mechanism node according to the group configuration file, and receives a fourth heartbeat request.
And after the nodes in the first mechanism belonging to the group determine that the number of the received fourth heartbeat requests is larger than a second threshold value, generating a group generation block of the group.
In the embodiment of the invention, no matter how the alliance chain is initialized, for the group division of the nodes, each node belonging to the group belongs to an organization which generates a group configuration file according to all certificates in the group and configures the group configuration file to the corresponding node installation package, so that the peer-to-peer property of the group division is maintained. Meanwhile, the private key of the node does not need to be transmitted between institutions, so that the security of the private key is ensured.
Further, the first organization generates a group configuration file of the group according to the third certificate and the group configuration item, including:
the first organization analyzes public key information and certificate fingerprints contained in the third certificate, and generates a group configuration file according to the group configuration item, wherein the group configuration file contains a group serial number of the group and a network connection address of the third node;
the first intra-mechanism node belonging to the group sends a third heartbeat request to a third node except the first intra-mechanism node according to the group configuration file, and the method comprises the following steps:
And the first intra-mechanism node belonging to the group sends the third heartbeat request to a third node except the first intra-mechanism node according to the group serial number and the network connection address of the third node.
In the implementation process, the first organization analyzes public key information and certificate fingerprints contained in the third certificate to generate a group serial number, and when the nodes of the subsequent group generate a group creation block, the group serial number information is put into the group creation block. Meanwhile, the first mechanism generates group configuration files such as group capacity required by the start of the blockchain and network connection addresses of nodes in the group. Thus, when the node in the first mechanism needs to send the heartbeat request to other nodes in the group, the heartbeat request can be sent to other nodes in the group according to the group network connection address of the node.

Step 308: node 11 sends a first heartbeat request to nodes 12 through 19 and receives a second heartbeat request according to the configuration file.
Step 309: the node 11 determines the number of received second heartbeat requests, if it is greater than the threshold value 5, then step 310 is performed, otherwise step 309 is performed.
Step 310: the nodes 11 make consensus.
Step 311: the federation chain initialization fails.
The second embodiment is a group partitioning process of a federation chain, and still uses the scenario in the first embodiment, where the steps of the second embodiment are shown in fig. 4, and include:
step 401: organization 1 determines from node certificates 110 through 190 that nodes 11 through 14 are a first group and nodes 15 through 19 are a second group.
