This is a creation in Article, where the information may have evolved or changed. Summary The Super Ledger (Hyperledger) is one of many projects under the Linux Foundation. The blockchain project, introduced in 2015 by IBM, Interlaken, and the financial companies, GP Morgan and other joint agencies, also includes 5 framework projects: Sawtooth, Iroha, Fabric, Burrow, Indy, and 3 tool projects:

In other words, you can use JUnit testing as a guide to implement code correctly.Now, if it's hard to understand, don't worry; I've provided a solution in com.makotojava.learn.blockchain.chaincode.solution in case you're stuck (or want to help with the implementation by reference).Writing the Java chain codeLet's start by introducing some of the background you need to know to implement the chain code approach in Chaincodelog. The Java chain code communicates with

After you get started, you can try using Web3.js to invoke, or install truffle or embark directly to develop your own real dapp application. Third, IBM
