Welcome to the basic blockchain GitHub repository! In this, we'll be creating a very basic blockchain using Java. This blockchain will implement a simple proof of work (mining) system, allowing you to marvel at the possibilities of blockchain technology.
To follow along with this tutorial, you will need the following:
- Java and JDK installed.
- Eclipse , Apache Netbeans or another IDE/Text Editor of your choice.
- Basic understanding of object-oriented programming (OOP) concepts.
A blockchain is essentially a chain or list of blocks. Each block contains its own digital fingerprint (hash), the hash of the previous block, and some data (which could be transactions, for example).
Here are some key points about our blockchain implementation:
- Hash = Digital Fingerprint: Each block contains a hash that serves as its digital fingerprint.
- Chaining Blocks Together: Each block's hash is calculated, in part, from the previous block's hash. This chaining ensures the integrity of the blockchain.
- Proof of Work Mining: Our blockchain requires proof of work mining to validate new blocks.
- Validity Check: The blockchain can be checked to ensure that its data is valid and unchanged.
To start creating your blockchain:
- Clone or download this repository to your local machine.
- Import the GSON library (
gson-2.8.2.jar) as a dependency. - Ensure you have JDK 1.8.0_77 or compatible version installed.
