Quick Start For HPB Developer

1. What is HPB?

Before diving into how to create a HPB application, we would like to introduce High Performance Blockchain core chain which can be found here: What is HPB.

2. How do I get access to the HPB source code?

The HPB source code is already available. If you want to view HPB source code, please visit Github.

3. Introduction to HPB node

From the perspective of developers, HPB nodes are divided into the maintenance node in main network running on the BOE board. There are 150 nodes in the first phase, and these nodes involves packaging block check of transaction. The rest are "synchronize nodes", mainly used by developers.

For the majority of developers, running a synchronize node is enough, as they don't need to actually mine any blocks. This article will describe how to set up a developer node.

4. HPB consensus election mechanism?

If you want to delve into HPB code, please read the following article to have a brief understanding of the HPB election consensus mechanism. Description of HPB consensus election mechanism

5. How to maintain HPB high performance nodes?

If you are HP nodes joining in HPB with the need for node installation and maintenance, please read the following articles:

HPB Node Server Security Upate Guide

HPB MainNet User Manual

6. How to connect to the HPB network?

For developers' needs, we have prepared the following articles. You can create a developer node locally in accordance with any of the following documents. The developer nodes do not need a BOE board.

If you do not wish to setup your own node, you can also use our public node for API requests at http://pub.node.hpb.io

7. How to interact with HPB main network?

• Web3 JavaScript API - This is JavaScript SDK used to connect HPB nodes.
• JSON RPC API - This is JSON RPC 2.0 API interacting with HPB nodes. This API is mainly for Web3 JavaScript API
• HPB Web3j Java SDK.
• Other SDK is developing.

9. How to build a HPB private chain

It is very convenient if you want to create a private chain by using HPB codes and develop DAPP on it, we have prepared this article for you.

HPB Private Chain Build Tutorial, please refer it to buld your exclusive development environment.

10.HPB DAPP Case

We would try our best to provide more development cases for reference. The development document is continously composed. Thanks for your patience!
