To facilitate search and identification, it is sometimes referred to as Golang. # Download the Linux version of Go install package $ wget https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz

00 Introduction The open source Blockchain distributed ledger--hyperledger Fabric, launched by the Linux Foundation, has ushered in the 1.2.0 version. The project focuses on performance and reliability, as well as cross-industry collaboration to drive blockchain and distributed ledger technology. Hyperledger Fabric can

We can consider starting with the default embedded Leveldb, which can be transferred to COUCHDB if additional complex rich queries are required. Modeling Chaincode Asset data as JSON is a good practice so that we can execute the complex rich queries we need in the future. Two.

chain code. testing with development mode Usually the chain code is started and maintained by the peer node. However, in "development mode," the chain code is built and started by the user. This pattern is useful during the fast coding/building/running/debugging of the chain code development phase. We started "Development mode" by leveraging the example of pre-generated sorting and channel artifacts from the sample development network. Therefore, the user can immediately enter the process of co

first of all thanks to the dark blue habitat, this tutorial is based on his tutorial [http://www.cnblogs.com/studyzy/p/7437157.html] collation, block chain technology developed quickly, in the great God's tutorial a little to add. In addition, there are also in the learning block chain students can contact me, we learn from each other. In the first contact with Hyperledger, very confused, do not know where to start. The tutor suggested that I not on
