Python Top Libraries You Need to Create ML Model

Creating a Model of Machine Learning in Python, you need two libraries. One is 'NUMPY' and the other one is 'PANDA'.


For this project, we are using Python Libraries to Create a Model.
What Are Key Libraries You Need I have explained in the below steps. You need Two.
NUMPY - It has the capabilities of CalculationsPANDA - It has the capabilities of Data processing. To Build a model of Machine learning you need the right kind of data. So, to use data for your project, the Data should be refined. Else, it will not give accurate results. Data AnalysisData Pre-processing How to Import Libraries in Pythonimportnumpy as np # linear algebra
importpandas as pd # data processing, CSV file I/O (e.g. pd.read_csv)

How to Check NUMPY/Pandas installed After '.' you need to give double underscore on both the sides of version. 
How Many Types of Data You Need You need two types of data. One is data to build a model and the other one is data you need to test the model. Data to build…

13 Worth-it Blockchain glossary useful for beginners

Bitcoin was the first project developed by using blockchain. My post is to share Blockchain keywords by using an example of Bitcoin.

blockchain useful words for beginners
Let us ready... 

Blockchain technology is new. Understanding the principles behind this technology makes you helpful to apply in your projects. 

Initially, the purpose Blockchain developed was to carry mining. In general, mining means search and find the value. Usually, minings are two types. Those are data mining and bitcoin mining.

Types of Blockchains

1. Private blockchains

  • Private blockchains are great for developers because they allow them to test ideas without using cryptocurrency. The developers’ ideas can remain a secret as well, because the data has not been published publicly.
  • Large institutions can capitalize on the security and permanence of blockchain technology without their transactions being public the way they are in traditional blockchains.

    2. Public Blockchains

    • Public blockchains are available to general public. An example is buying an art piece from a vendor located in another country.

    3. Hybrid Blockchains

    • These are combination of public and private.

    Terminology Blockchain

    1. Blockchain - only blocks involved. The data which was finalized stored in blocks.
    2. Bitcoin Ledger = Blockchain
    3. Bitcoin Ledger - It is a public ledger
    4. Ledger or Blockchain - The chain of blocks
    5. Functions of Blockchain - It validates each transaction, Keeps track and verifies ownership
    6. Double Spending- It prevents duplicating the Crypto currency for using next time.
    7. Consensus mechanism - It is also called PoW (proof of work). This mechanism avoids double spending
    8. Group of Transactions - When a new group of transactions created, those will be added to the blockchain.
    9. Hash - Group of transactions created a Hash. This hash will be stored along with group of transactions in the Blockchain. Hashing is the top security mechanism in blockchain.
    10. Mining - It doesn't create Bitcoins, and alter or modify blockchain. The miners will be rewarded with Bitcoins

    In Hyperledger the communication entities are called Nodes.

    2). What are the three different types of Nodes?
    - Client Node
    - Peer Node
    - Order Node
    The Client node initiates transactions. The peer node commits the transaction. The order node guarantees the delivery.

    3). What is Channel?
    A channel in Hyperledger is the subnet of the main blockchain. You c…
