How Blockchain Manages Transactions - Quick Recap

  • Blockchain stores each transaction in Blocks. No one can tamper or change the details. 
  • The people who are making a transaction in Blockchain world they both have same copies. 
  • No possibility of changing these records by parties involved. So it is robust.

Key Advantages of Blockchain

  1. The ledger details distributed.
  2. Distributed-data available to all parties, and one cannot tamper this data. 
  3. Every transaction is Public. That means only people who have access can see the information. 
  4. Stores all records permanently.
  5. One cannot edit or manipulate the data.
  6. Hacking is not possible.  In Blockchain one cannot hack the data. Since it is distributed.
  7. The centralized processing is slower. Whereas Blockchain is much faster. Verification and completing a transaction is much faster.
  8. The centralized system is expensive. Each server in the network charges some amount as processing fee. In Blockchain, you can eliminate intermediaries.
  9. The Centralized databases are expensive to carry transactions of low value. The fee to pay intermediaries is huge.
  10. Data in Blockchain cannot be edited. In the case of Centralized databases, the Banks or Private Organizations can edit it.
  11. Maintenance of Blockchain is cheaper.

Key Disadvantages of Blockchain

  • Publish carefully. Once publishes you cannot take back.

Python Function: How to Write Error Logic

Image
Python is one of the top programming languages. Python does support Functions. While writing functions you also need to consider some errors. Those are called exceptions. I am explaining how to give error logic in a function of Python.



Exception-handling means to have logic for error scenarios. Writing exception I will show in a simple Function.

In this post I will give you syntax for writing function and exception. 
Here is my simpleFunction that multiplies two numbers.
Logic to write Function in Python to Multiply Two Numbers 
def product (num1,num2): prod=num1*num2 print( ' The product of the numbers is \t: '+str(prod)
Parameters used the Python Function
 The 'def' means you are defining function with a name of 'product'.In the parameters of 'product', you can see TWO variables. Those are to take input from the user for multiplication.prod=num1*num2. That means product of two numbers assigning to 'prod' variable. Python is dynamic language and you no ne…
