We know that when the constructor of a class is set to private, it means that we cannot create the object directly by using the New keyword, and we can use Sun.misc.Unsafe to achieve the purpose of creating the object, which is Java's underlying operation-based API. You can directly perform underlying operations, such as obtaining an offset address for a property, or even loading the class file bytecode into memory directly, breaking through the Java Virtual machine sandbox limit.1.

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) that have been agreed before. Here is a description of the choice of endorsing peer is a certain range, not in all the endorsing peer arbitrary choice, is the transaction is the Chaincode and the Chaincode
The point-to-point (peer-to-peer) communication of fabric is built on a stream-based message grpc that allows bidirectional flow. It uses protocol buffers to serialize the data structure that is transferred between peer. Protocol buffers is a language-independent, platform-independent technology that has an extensible mechanism to serialize structured data. Data structures, messages, and services are described using PROTO3 language annotations. 3.1 Ne
