The main introduction through the use of replacement filter text and wrinkled silk fabric background perfect combination, suitable for novice friends to learn, hope friends like. The replacement of Ytterbium in PS (displace) seems to be less noticeable, some people may not know its role. Now let's explore its potential and analyze how it works, and see how this filter, combined with layer blending, combines text with a wrinkled silk background that wo

Hyperledger source code Analysis of Fabric Deliver means that the client obtains data from the ordering service via the Grpc interface (for example, data from a specified block). The Orderer node receives the request message, which is first given to the Deliver of the server structure in the Orderer.common.server package (SRV ab. Atomicbroadcast_deliverserver) Error method processing. This method further invokes the Handle of the deliverserver structu

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. These request messages are given to the broadcast (SRV ab) of the server structure in the Orderer.common.server package. Atomicbroadcast_broadcastserver) Error method processing. This method will mainly call the Handle (SRV ab) of the HANDLERIM

General use of fabric, mostly with the remote interaction, and in the interaction, in addition to the logic of simple code, time is also accompanied by the transmission of files, and there may be a lot of files in the file. Whether we can make a judgment, if the file exists, then we do not upload, look at the code # for a test @task @roles ("Mgmt") def Test (): if Int (run ("[E '/etc/passwd1 '] echo 11 | | echo ") = = one: print" Yes, f

Application development Configuration and build You can use Go to develop applications and use the APIs available in the Hyperledger Fabric SDK Go to invoke the chain code to complete transactions in the blockchain network. At this stage we run the test project first. Steps: 1. Sample application service-side code run 2. Download the certificate 3. Build the Certificate directory 4. Fabric SDK Configuration

Fabric is a Python class library that uses SSH protocol-based command-line tools for application Deployment and System task management, and here are two ways that fabric code runs in parallel: 1: Parameter-P From FABRIC.API import * host1 = ' root@ip1:22 ' host2 = ' root@ip2:22 ' env.hosts = [Host1, host2] Env.pass Words = { host1: "P1", host2: "P2" }

first, fabric network structure (temporarily excluding CA) As shown in the figure above, in the Fabric network, o indicates that ORDERER,P represents PEER,EP representative endorsing Peer (endorser), CC represents Chaincode, and client, Channel, Ledger, Transaction, which makes up the entire network, describes each of these elements: Clients: A client installed at a node (Peer) can initiate a request to

The 1.Chaincode interface must be implemented by all the code on the chain, and the fabric runs the transaction by invoking these specified functions Call the INIT function to allow code on the chain to initialize internal data after the container has established a connection and then deploys the transaction Init (stub chaincodestubinterface, function string, args []string) ([]byte, error) Each call to the transaction invokes the Invoke interface.
