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

First of all, a simple look at the above transaction flow chart, the following is a detailed diagram of the entire fabric of the whole business process: 1. The block chain client sends the transaction request to all endorsed nodes (endorsing peer)

bringing up a kafka-based ordering Service The sorting service needs to handle all transaction messages in the FABIRC network, which is the key to the whole network. Fabric currently (2018/01) supports two types of sorting: Solo and Kafka. In the

Third, the core package of the BSSCP (Blockchain encryption service provider) package of SW Encryption Package Package Content Description: The entire WS package according to the file type, basically contains a few pieces: AES encryption module go

Peer service is the primary service. The service supports a variety of peer commands. Includes query status, start, Stop node service, and so on. The startup process is in Peer/main.go. Serve function The most important is the Func serve (args

1. During the network initialization process, the node is connected to the other peer as the client during the creation of the node engine during the execution of the following Peerserver, err = Peer. Newpeerwithengine (Sechelperfunc, Helper.)

This is a creation in Article, where the information may have evolved or changed. The entire functional architecture is shown. Includes three main components: Blockchain service (Blockchain), Chain Code Service (Chaincode), Member Rights Management

Take fabric-samples/balance-transfer Example: 1. Specific process The FABRIC/EXAMPLES/E2E_CLI directory contains files network_setup.sh for one-click Deployment environments and test Chaincode sample code. This includes two sections, one that

Anchor Peer-Anchor node is a peer-to-peer node in the channel that can be detected by all peer nodes and can communicate with it. Each member of the channel has one (or more, in case of a single point of failure) Anchor node that allows nodes

I. Initiation of Transaction When the client wants to initiate a transaction, it will first send a propose message to a set of endorser nodes it chooses, the message mode has the following two kinds, the node is free to choose (may have more kinds):

About Super Ledger December 2015, led by the Linux Foundation, IBM, Intel, Cisco and so on jointly announced the establishment of Hyperledger joint project. Super Ledger project provides open source reference implementation for transparent, open and decentralized enterprise-class distributed ledger technology The current super ledger community already has Aiyisai, Onchain, near-win, Bitse, Boobie, 31 Heavy Industries, Wanda, Huawei and many othe

. 1.1 Compiling build Cryptogen Now that we have the source code for the fabric, we can easily compile the required program with the Make command. Fabric officially provides a portal specifically for compiling Cryptogen, and we just need to run the following command: CD ~/go/src/github.com/hyperledger/fabric make Cryptogen The system returns results after the run: Build/bin/cryptogen cgo_cflags= "" Gobin=/home/studyzy/go/src/github.com/
