This Go project provides a basic implementation of a blockchain, demonstrating key concepts such as blocks, transactions, mining, and the Merkle root.
The blockchain consists of the following main components:
-
Block Structure: Represents a block in the blockchain, containing a version, previous hash, difficulty level, timestamp, Merkle root, nonce, the number of transactions, and a list of transactions.
-
Blockchain Structure: Manages the chain of blocks and includes methods for creating the blockchain, adding blocks with transactions, and calculating the Merkle root.
-
Transaction Structure: Represents a transaction with sender, receiver, and amount.
-
Enter Difficulty:
- When running the program, the user is prompted to enter the mining difficulty for the blockchain.
-
Generate Transactions:
- Transactions are generated with random sender, receiver, and amount values.
-
Create Blockchain:
- The blockchain is created with the specified difficulty.
-
Mine Blocks:
- Blocks are mined with transactions, and the Merkle root is calculated.
-
Output Merkle Root:
- The final Merkle root of the blockchain is displayed.
-
Note:
- The code includes commented-out sections that provide detailed information about each block. Uncomment and use these sections for more detailed block information.
Enter Difficulty: 3
Merkle Root: 14bb1ce74a0f120e5a1a3e5ff8a5370323bae66eaab349e1c15e9cf442963fb6This project relies on the standard Go libraries and does not require any external dependencies.
This blockchain implementation serves as an introductory example of building a blockchain in Go. Developers are encouraged to explore, modify, and extend the codebase to enhance their understanding of blockchain concepts in a practical setting.
Feel free to experiment, customize, and delve into the code to gain insights into the inner workings of a basic blockchain.
