Create Your Own Blockchain Using Python
Blockchain Technology Basics
Blockchain technology is a distributed database system that maintains a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a cryptographic hash of the previous block, a timestamp, and transaction data. Once a block is added to the chain, it cannot be altered retroactively without altering all subsequent blocks, which requires collusion of the network majority.
Creating a Blockchain in Python
To create a blockchain in Python, you can use the following steps:
- Create a class to represent a block.
- Create a function to add a block to the chain.
- Create a function to get the latest block in the chain.
- Create a function to verify the integrity of the chain.
Once you have these functions, you can create a blockchain by instantiating the Block class and calling the add_block() function to add blocks to the chain. You can then use the get_latest_block() and verify_chain() functions to verify the integrity of the chain.
