Become an NFT Developer with Best Practice Way Part 2: Implement How Blockchain works using Python
in the previous chapter, we discuss the fundamental of blockchain, so in this chapter, we will discuss how to implement Blockchain Works using Python, so let’s see the table of content
- Creating Blockchain Class and Constructor
- Creating Method to get Transaction
- Creating Sample Transaction
Creating Blockchain Class and Constructor
in first step creating blockchain class and the constructor
in this constructor, we have a previous hash property and transaction list parameter, and we join all the transaction list with the previous hash and separate them with -
after separating the string we created a hash with the sha256 method from the hashlib module on python.
Creating a method to get Transaction
after creating the constructor, we need to get transaction result so creating a method for it
in this method, we print the result of the transaction
Creating Sample Transaction
now creating simple transactions to see how blockchain works
and we see if we changed data the hash is changed differently
Conclusion
In this simple program, we explain how blockchains work and create the unique token using hash, so we can easily understand it, thanks for reading, source code available on Github, see you in the next chapter
