Note: If it is windows, please look at the following Windows extras; Docker and Docker Compose Below you talk about installing Docker and Docker compose. MAXOSX, *nix, or Windows 10 requires the installation of Docker V1.12 or a later version. Older versions of Windows need to be installed first: Docker Toolbox before installing Docker V1.12 or later.

current fabric there is limited development resources, so in 1.0 will not do, may be achieved in the future. COUCHDB Installation Now let's talk about this couchdb. COUCHDB is a database of key values for a full local restful API, which means we don't need any clients, we just need to operate the database via HTTP requests. Leveldb is a peer local database, then certainly and peer one-to-one relationship, then COUCHDB is a network database, should and peer what kind of relationship. In a produc

Hyperledger source code Analysis of Fabric The sorting service plays a very central role in the Super Ledger Fabric network. All transactions need to be sorted globally before they are sent to committer for validation acceptance. In the current architecture, the function of the sorting service is extracted, as a separate Fabric-orderer module to implement, the code is mainly in the Fabric/orderer directory. The following Kafka as a consensus plug-in a

Hyperledger source code Analysis of Fabric The Orderer node startup is implemented by the main () method under the Orderer package and further calls to the main () method in the Orderer/common/server package. The core code is shown below. Main is the entry point of Orderer Processfunc main () { fullcmd: = Kingpin. Mustparse (app. Parse (OS. Args[1:]) //"version" command if Fullcmd = = version.

Hyperledger source code Analysis of Fabric Broadcast means that the client sends the request message (for example, after the endorsement transaction is completed) to the ordering service via the Grpc interface.

The entities involved in Hyperledger Fabric 1.0 include the following: FABRIC-CA: Mainly responsible for the maintenance of the certificate of the entity in the network; Peer: mainly responsible for the implementation of intelligent contracts, record books; Order: mainly responsible for the accounting content of the consensus. 1.0 architecture can be based on the actual needs of the network through the Certificate of Security Domain Division manag

The previous analysis program looked at the details of the analysis, so without the concept of framework, took two days to analyze the Hyperledger fabric architecture design, analysis of the program does not reference any information, such as error welcome correction, common progress. The author has the following questions before the detailed analysis procedure: 1) How the CLI (command line) client sends a command to a peer node 2) How the peer node
