It is to be appreciated that the target blockchain service platform can be any one or more of the second blockchain service platforms 102A, 102B, and 102C in fig. 1, and if the target blockchain service platform does not directly establish a peer-to-peer connection with the first blockchain service platform, for example, if the target blockchain service platform is the second blockchain service platform 102B, the first blockchain service platform establishes a peer-to-peer connection with the target blockchain service platform 102B.
The first block chain service platform and the second block chain service platform can be respectively internally provided with a personal computer, a notebook computer, a smart phone, a tablet personal computer, an internet of things device and a portable wearable device, and the internet of things device can be an intelligent sound box, an intelligent television, an intelligent air conditioner, an intelligent vehicle-mounted device and the like. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, and the like. The first blockchain service platform and the second blockchain service platform can be respectively realized by independent servers or a server cluster consisting of a plurality of servers. It can be understood that the first and second are only used for distinguishing different blockchain service platforms, and the federation chain building method provided by the embodiment of the present application may also be executed by the second blockchain service platform.
In an embodiment, as shown in fig. 2, a federation chain building method is provided, which is described by taking an example that the method is applied to the first blockchain service platform in fig. 1, and includes the following steps:
step 202, the first blockchain service platform is connected to the peer-to-peer network based on the set network connection service program; acquiring organization information in each second block chain service platform in the peer-to-peer network through the connected peer-to-peer network; the first block chain service platform determines a target organization to be established with the alliance chain from all organizations based on the organization information.
The Blockchain Service platform, namely, a "Blockchain as a Service" (BaaS) platform, is a Blockchain open platform which embeds a Blockchain frame into a cloud computing platform, provides a convenient and high-performance Blockchain ecological environment and ecological supporting Service for developers by using the deployment and management advantages of cloud Service infrastructure, and supports business expansion and operation support of the developers. Generally, a complete BaaS solution includes four main links, namely, device access, access control, service monitoring, and a blockchain platform. Peer-to-Peer (Peer to Peer, P2P) networks are an internet infrastructure that relies on groups of users (peers) to exchange information without a central server. It will be appreciated that the nodes in a P2P (Peer to Peer) network may communicate directly with each other without the need for a central server. Each node acts as a server, provides services for other nodes, and simultaneously enjoys the services provided by other nodes. A federation chain refers to a block chain which is managed by a plurality of organizations together, each organization manages one or more nodes, and data of the organizations only allows different organizations in the system to read, write and send. The network connection service program refers to a program for connecting a peer-to-peer network.
In particular, each blockchain service platform may share information of an organization in the platform based on a peer-to-peer network. The first blockchain service platform can be connected to the peer-to-peer network based on the set network connection service program, and acquires the organization information in each second blockchain service platform in the peer-to-peer network through the connected peer-to-peer network. The first block chain service platform can determine a target organization to be used for building a alliance chain from all organizations based on the information of the organizations.
In one embodiment, the network connection service runs when the first blockchain service platform is started, and connects the first blockchain service platform to the peer-to-peer network.
In one embodiment, a peer-to-peer connection may be established between any two nodes in a peer-to-peer network. The first blockchain service platform can acquire information of each node in the peer-to-peer network, that is, connection information of each second blockchain service platform, through the network connection service program, so as to establish peer-to-peer connection with the second blockchain service platform. It is understood that a node in a peer-to-peer network is essentially a blockchain service platform, a peer-to-peer connection between two nodes is essentially a peer-to-peer connection between two blockchain service platforms, and a peer-to-peer network is essentially a network formed by connecting blockchain service platforms in series by a peer-to-peer connection.
In one embodiment, a newly added node, that is, a blockchain service platform connected to the peer-to-peer network for the first time, may connect to the peer-to-peer network through the network connection service program, and obtain connection information of other blockchain service platforms to establish a new peer-to-peer connection. It is understood that other blockchain service platforms in the peer-to-peer network may obtain information of the first connection to the blockchain service platform in the peer-to-peer network.
Step 204, the first block chain service platform determines a second block chain service platform to which the target organization belongs, and a target block chain service platform is obtained; the first blockchain service platform sends alliance chain invitation information to the target blockchain service platform based on the peer-to-peer connection which is pre-established between the first blockchain service platform and the target blockchain service platform.
The alliance chain invitation information is used for inviting target organizations to jointly build alliance chains. Peer-to-peer connection refers to a connection for implementing peer-to-peer communication between the first blockchain service platform and the target blockchain service platform. The target block chain service platform refers to a second block chain service platform to which the target organization belongs.
Specifically, the first blockchain service platform determines a second blockchain service platform to which the target organization belongs, and the second blockchain service platform is used as the target blockchain service platform. The first block chain service platform realizes point-to-point data transmission with the target block chain service platform through peer-to-peer connection pre-established between the first block chain service platform and the target block chain service platform, and sends alliance chain invitation information to the target block chain service platform so as to invite a target organization to jointly build an alliance chain. It is to be appreciated that after establishing the peer-to-peer connection, data is transferred directly between the first blockchain service platform and the target blockchain service platform without passing through a central server.
And step 206, the first block chain service platform receives an invitation feedback result returned by the target block chain service platform, so as to build the alliance chain according to the invitation feedback result.
The invitation feedback result refers to a feedback result of the target organization aiming at the invitation information of the alliance chain.
Specifically, the target blockchain service platform may receive federation chain invitation information sent by the first blockchain service platform, and forward the federation chain invitation information to the target organization. The target blockchain service platform may obtain the invitation feedback result and return the invitation feedback result to the first blockchain service platform. The first blockchain service platform can receive the invitation feedback result so as to build a alliance chain according to the invitation feedback result.
In the alliance chain building method, the first block chain service platform is connected to a peer-to-peer network based on a set network connection service program; acquiring information of organization in each second block chain service platform in the peer-to-peer network through the peer-to-peer network; the first block chain service platform determines a target organization of a to-be-built alliance chain from all organizations based on organization information; the first block chain service platform determines a second block chain service platform to which the target organization belongs, and a target block chain service platform is obtained; the first blockchain service platform sends alliance chain invitation information to the target blockchain service platform based on peer-to-peer connection pre-established between the first blockchain service platform and the target blockchain service platform; the alliance chain invitation information is used for inviting a target organization to jointly build an alliance chain; and the first block chain service platform receives an invitation feedback result returned by the target block chain service platform so as to build the alliance chain according to the invitation feedback result. The first block chain service platform can realize mutual discovery with each second block chain service platform in the peer-to-peer network based on the peer-to-peer network, acquire organization information of each second block chain service platform, and invite the target organization of the target block chain service platform to jointly build the alliance chain based on peer-to-peer connection pre-established between the target block chain service platform and the target block chain service platform after determining the target organization of the alliance chain to be built, so that alliance chain building is realized for organizations of different block chain service platforms.
In one embodiment, obtaining information for an organization in each second blockchain service platform in the peer-to-peer network comprises: determining a second block chain service platform connected to the first block chain service platform in the peer-to-peer network to obtain a direct connection platform; acquiring information of an organization in a direct connection platform connected to and information of an organization in a connection association platform based on peer-to-peer connection with the direct connection platform; the connection association platform is a second blockchain service platform in the peer-to-peer network and having a connection relationship with the direct connection platform.
The direct connection platform refers to a second blockchain service platform that establishes an equality connection with the first blockchain service platform, that is, the second blockchain service platform that is directly connected with the first blockchain service platform.
In one embodiment, the connection relationship may include at least one of a direct connection relationship and an indirect connection relationship. The connection association platform may have at least one of an indirect connection relationship and a direct connection relationship with the direct connection platform. For example, the connection association platform may be a second blockchain service platform that establishes an peer-to-peer connection with the direct connection platform, i.e., the direct connection platform of the direct connection platform. Although the connection association platform does not establish peer-to-peer connection with the first blockchain service platform, the connection association platform and the first blockchain service platform have indirect connection relation due to the peer-to-peer connection established with the direct connection platform. It can be understood that the direct connection platform and the first blockchain service platform have a direct connection relationship; the connection association platform and the first block chain service platform have an indirect connection relationship.
Specifically, the first blockchain service platform may determine a second blockchain service platform connected in the peer-to-peer network, and use the second blockchain service platform as a direct connection platform. The first blockchain service platform can transmit data point to point with the direct connection platform through the peer-to-peer connection between the first blockchain service platform and the direct connection platform, acquire information of organizations in the direct connection platform connected to the first blockchain service platform, and acquire information of organizations in the connection association platform through the direct connection platform. It can be understood that when two blockchain service platforms a and B are connected, not only the known organization information is shared with each other, but also the organization information synchronized by one blockchain service platform a from the other blockchain service platform is also shared by the other blockchain service platform B connected to the blockchain service platform a.
In this embodiment, a second blockchain service platform to which a first blockchain service platform is connected in a peer-to-peer network is determined to obtain a direct connection platform; based on the peer-to-peer connection between the direct connection platform and the direct connection platform, the information of the organization in the connected direct connection platform and the information of the organization in the connection association platform are obtained, the sharing of the information of each organization in the equality network is realized, and the establishment of the alliance chain is conveniently carried out after the target organization in each block chain service platform is determined.
In one embodiment, the connection relation between the connection association platform and the direct connection platform comprises a direct connection relation and an indirect connection relation; based on the peer-to-peer connection with the direct connection platform, acquiring information of an organization in the direct connection platform connected to and acquiring information of an organization in the connection association platform comprise: determining a second block chain service platform which has a direct connection relation with the current platform by taking the direct connection platform as the current platform to obtain the connection platform of the current platform and obtain information organized in the connection platform of the current platform; and taking the connection platform of the current platform as the current platform, returning to the step of determining the second block chain service platform which has a direct connection relation with the current platform to obtain the connection platform of the current platform, and acquiring the information organized in the connection platform of the current platform to iterate until an iteration stop condition is met, so as to obtain the information organized in the connection association platform of the direct connection platform.
Specifically, the first blockchain service platform may use the direct connection platform as a current platform, determine a second blockchain service platform having a direct connection relationship with the current platform, obtain a connection platform of the current platform, and obtain information organized in the connection platform of the current platform; and taking the connection platform of the current platform as the current platform, returning to the step of determining the second block chain service platform which has a direct connection relation with the current platform to obtain the connection platform of the current platform, and obtaining the information organized in the connection platform of the current platform to iterate until the current platform does not have the connection platform, namely, the connection association platform of the first block chain service platform iterates completely to obtain the information organized in the connection association platform of the direct connection platform.
In one embodiment, fig. 3a and 3b are schematic diagrams of obtaining information of each tissue. In fig. 3a, the blockchain service platform 1, the blockchain service platform 2, the blockchain service platform 3, and the blockchain service platform 4 are connected to the peer-to-peer network, i.e., all become nodes in the peer-to-peer network. The blockchain service platform 1 establishes peer-to-peer connections with the blockchain service platform 2 and the blockchain service platform 3, respectively, that is, both the blockchain service platform 2 and the blockchain service platform 3 are direct connection platforms of the blockchain service platform 1. The blockchain service platform 4 establishes peer-to-peer connection with the blockchain service platform 2 and the blockchain service platform 3, respectively, that is, the blockchain service platform 4 and the blockchain service platform 1 have an indirect connection relationship and belong to a connection association platform of the blockchain service platform 1.
As shown in fig. 3b, the organizations included in the blockchain service platform are shown in the same color block, for example, the organization 1 and the organization 2 are the same as the color of the blockchain service platform 1, that is, the organization in the blockchain service platform 1 is shown to include the organization 1 and the organization 2. The organization 3 and the organization 4 are the same color as the block chain service platform 2, and the organization used in the block chain service platform 2 is illustrated to include the organization 3 and the organization 4. Similarly, the organization in the blockchain service platform 3 includes an organization 5; the organization in blockchain service platform 4 includes organization 6.
The blockchain service platform 1 can directly communicate with the blockchain service platform 2 and the blockchain service platform 3 to obtain information of the organization 3, the organization 4 and the organization 5. The blockchain service platform 2 or the blockchain service platform 3 is used as a current platform, and the blockchain service platform 6 which has a direct connection relationship with the blockchain service platform 2 or the blockchain service platform 3 is determined, so that the information of the organization 6 is obtained from the blockchain service platform 6 through the blockchain service platform 2 or the blockchain service platform 3. It will be appreciated that the blockchain service platform 2 and the blockchain service platform 3 may communicate directly with the blockchain service platform 4 to obtain information for the organization 6. Similarly, because the blockchain service platform 1, the blockchain service platform 2, the blockchain service platform 3 and the blockchain service platform 4 have an indirect or direct connection relationship, organization information in one blockchain service platform can be acquired by the remaining blockchain service platforms, thereby realizing the sharing of information of each organization. The organizations 1-6 shown in each blockchain service platform in fig. 3a represent that all the organized information in each blockchain service platform in the peer-to-peer network is synchronized.
In this embodiment, the connection association platform having the direct connection relationship and the indirect connection relationship with the direct connection platform is iterated to obtain information of an organization of each block chain service platform in the peer-to-peer network, so that a union chain is established for organizations in different block chain service platforms.
In one embodiment, the information of the organization comprises connection information of a second blockchain service platform to which the organization belongs; before the first blockchain service platform sends alliance chain invitation information to the target blockchain service platform based on the peer-to-peer connection pre-established between the first blockchain service platform and the target blockchain service platform, the method further comprises the following steps: the first blockchain service platform establishes peer-to-peer connection with the target blockchain service platform based on the connection information of the target blockchain service platform.
The connection information refers to information for establishing a peer-to-peer connection.
Specifically, the target blockchain service platform may be a connection association platform of the direct connection platform of the first blockchain service platform. The connection information may be a connection address of the target blockchain service platform, and the first blockchain service platform may establish peer-to-peer connection with the target blockchain service platform through a network connection program according to the connection address of the target blockchain service platform.
In this embodiment, before the first blockchain service platform sends the alliance chain invitation information to the target blockchain service platform based on the peer-to-peer connection pre-established with the target blockchain service platform, the method further includes: the first blockchain service platform establishes peer-to-peer connection with the target blockchain service platform based on the connection information of the target blockchain service platform.
In one embodiment, the sending, by the first blockchain service platform, the alliance chain invitation information to the target blockchain service platform based on a pre-established peer-to-peer connection with the target blockchain service platform includes: the first block chain service platform sends alliance chain invitation information to the target block chain service platform based on peer-to-peer connection pre-established with the target block chain service platform, so that the target block chain service platform forwards the alliance chain invitation information to a target organization, and forwards the invitation feedback result to the first block chain service platform after receiving the invitation feedback result sent by the target organization.
Specifically, the first blockchain service platform transmits data point to point with the target blockchain service platform through a peer-to-peer connection pre-established between the first blockchain service platform and the target blockchain service platform, and sends alliance chain invitation information to the target blockchain service platform. And the target block chain service platform receives the alliance chain invitation information, forwards the alliance chain invitation information to the target organization, and forwards the invitation feedback result to the first block chain service platform after receiving the invitation feedback result sent by the target organization. It can be understood that, because organization information is shared, each blockchain service platform knows the blockchain service platform where each organization is located, and the inter-organization communication is handled by the blockchain service platform and is based on establishing peer-to-peer connection.
In this embodiment, the first blockchain service platform sends the alliance chain invitation information to the target blockchain service platform based on a peer-to-peer connection pre-established with the target blockchain service platform, so that the target blockchain service platform forwards the alliance chain invitation information to the target organization, and forwards the invitation feedback result to the first blockchain service platform after receiving the invitation feedback result sent by the target organization, and peer-to-peer communication between the blockchain service platforms is realized through the peer-to-peer connection, and the alliance chain invitation information can be transmitted only if the peer-to-peer connection is established, thereby ensuring the security of the alliance chain establishment process.
In one embodiment, the federation chain invitation information is initiated by an organization in the first blockchain service platform; the first block chain service platform receives an invitation feedback result returned by the target block chain service platform, and the establishment of the alliance chain according to the invitation feedback result comprises the following steps: the first block chain service platform receives an invitation feedback result returned by the target block chain service platform; if the invitation feedback result indicates that the target organization agrees to the invitation, the target organization is added to the federation chain based on the organization initiating the invitation.
Specifically, an organization in the first blockchain service platform initiates alliance chain invitation information to a target organization in the target blockchain service platform, and the first blockchain service platform can send the alliance chain invitation information to the target blockchain service platform. The target blockchain service platform may forward the federation chain invitation information to the target organization, and the target organization may reject or approve the federation chain invitation information. The target blockchain service platform may obtain an invitation feedback result of the target organization, and return the invitation feedback result to the first blockchain service platform, and the first blockchain service platform may send the received invitation feedback result to the organization that initiated the invitation. If the invitation feedback result represents that the target organization agrees to the invitation, the organization initiating the invitation can add the target organization to the federation chain; if the invitation feedback result represents that the target organization refuses the invitation, the organization initiating the invitation cannot add the target organization to the federation chain. It can be understood that the federation chains are built together by different organizations, and the organization initiating the invitation can create the federation chains from scratch with the target organization, and can also add the target organization to the existing federation chains to complete the building of the federation chains.
In one embodiment, a schematic diagram of an invitation to a target organization is shown in FIG. 4. The blockchain service platform 1 and the blockchain service platform 4 establish peer-to-peer connection in advance. An organization 1 in the blockchain service platform 1 can acquire information of each organization in the blockchain service platform 4 through the blockchain service platform 1, the organization 1 can select the organization 6 as a target organization, and sends alliance chain invitation information to the blockchain service platform 4 where the organization 6 is located through the blockchain service platform 1, and the blockchain service platform 4 forwards the alliance chain invitation information to the organization 6.
