In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
As shown in fig. 1, the process of establishing a federation chain in the present invention is as follows:
the creation of a federation chain generally starts with the network of each member node, then a CA (certificate issuing authority) distributes a certificate and a secret key for each organization member of the federation, a configuration file is generated according to a read-write permission strategy, on-chain organization members and endorsement strategies of each federation member, and then an founding block is generated according to the configuration file. The creation block is assigned to each member node, and then the node is started, a chain is created, etc.
The creation block is a configuration block, and information such as organization member information in a chain, authority of each organization member in the chain, certificate of each organization member in the chain, endorsement policy of chain management (mainly referring to upgrading operation of the chain) and the like is specified in the configuration block, so that the isolation, safety, member admission and other characteristics of the chain are determined. The endorsement strategy is specified when a chain is created, and when the chain is upgraded, a signature strategy of an in-chain member for the upgraded content is carried out, and the endorsement strategy mainly comprises the following steps: signing endorsements by most members in the chain, signing endorsements by any member in the chain, signing endorsements by appointed members in the chain and signing endorsements by all members in the chain.

the restful interface is provided for the user, and the caller can operate through the command line or the front-end interface. And the background server interacts with the block chain network node through the block chain SDK to realize the operation of the block chain network node. The background server side mainly provides service interfaces for adding alliance chain organization members, deleting alliance chain organization members and changing alliance chain organization member authority. The background server side generates an upgrade file according to the upgrade information of the alliance members, then obtains signature information of the alliance members according to an endorsement strategy, and finally sends the upgrade file with the multi-party signature to a consensus node of a block chain network to upgrade the configuration block, so that the purpose of upgrading the alliance chain is achieved.
Wherein, the configuration block mainly includes:
1. the configuration of the consensus node specifically comprises the following steps:
read-write permission: admin, write, read rights;
block verification strategy: ANY, ALL, MAJORITY;
common type, mainly including solo, raft, pbft;
transaction packaging configuration information, such as batch size, etc.;
packing timeout time
Maximum number of chains
The modification authority of the consensus node is generally admin authority, namely reading and writing can be carried out;
the organization information of the consensus node stores all organization information through a map table, and mainly comprises certificate information and a signature strategy.
2. The application configuration mainly aims at the accounting node, and specifically comprises the following steps:
read-write permission: admin, write, read rights;
ACL (access control list) configuration, mainly for some API interfaces, e.g. getlock interface is Read right;
the modification authority of the accounting node is generally admin authority, namely reading and writing.
3. The organization member configuration is as follows:
organizational signature policy
Organizing configuration information, storing all organization information through a map table, wherein the organization information comprises the order node configuration of an organization, and the organization information mainly comprises certificate information and a signature strategy;
creation of chains policy configuration is typically an ANY policy, i.e. ANY member of an organization can create a chain.
The configuration block specifies the authority, signature strategy and the like of each organization, each consensus node, each accounting node and each organization member. Where an organization may contain multiple consensus nodes and multiple accounting nodes. When the node operates, the operation comprises a reading operation, such as reading information on a chain; write operations such as initiating a transaction generation block, writing an account book, and upgrading configuration block operations; these operations need to be verified according to the corresponding permissions in the configuration block. The definition of the configuration block realizes the authority management of the block chain, different authorities can be defined aiming at different organizations, and the safety of the chain is effectively ensured.
