Blockchain Smart Contract Theory Behind

The smart contract in Blockchain is a kind of software application that works without human intervention based on the transaction logs and provide a solution to the user request. 
I want to share the back end mechanism in the Smart Contract of Blockchain.

Smart Contract Mechanism What is Smart ContractA smart contract is a protocol which can auto-execute, facilitate, verify, or enforce the negotiation of a contract.Agreement between two parties you can say as a contract.Incorporating the rules of the physical contract into the computing world, you can say as a smart contractBlockchain supports you to create smart contracts.Smart Contracts are self-executing programs which run on the blockchain and are capable of enforcing rulesUsing Blockchain as a platform and making an agreement or contract between more than two parties, you can say as Smart Contract.Traditional Markets  4 Top Benefits of Smart ContractCurrently, smart contracts are being used only in Crypto CurrenciesNow Smart Contra…

How to use Pandas Series Method top ideas

I am sharing the ideas on how to use a series constructor on a dataset using Python pandas.
...
 

A series is an object of Pandas that represents a one-dimensional labeled array capable of holding any data type (integers, strings, floating-point numbers, Python objects, etc.).

Example of Dataframe data


Dataframe data


Example of Single Dimension Data

A single dimension data you can derive as (index, value):


 Index Value
 1 10           
 2 40
 3 01
 4 99


So, in the above "Dataframe" when you pull out the data of a single column with its index, you can say it as one-dimensional data.

When one index has multiple values in brackets, you can say it as a multi-dimensional array. The example is (1, (10,20))
mySeries = pd.Series(data, index=index)
Here, pd is a Pandas object, and data refers to a Python dictionary of "ndarray" or even a scalar value.

A Series is a single column of data from a DataFrame. It is a single dimension of data, composed of just an index and the data.

How to get Values and Index using Series Method in Python Pandas

In the first example, I show how to construct single dimension data and how to get index and values from the series data.


>>>mySeries = pd.Series([10,20,30], index=[1,2, 'a'])

In the above example, in the index, I have given 'a'. So for alpha index types, you need to give in quotes.

The result from the above code is you got both values and index.

Hyperledger Fabric: 20 Real Interview Questions

Image
I am practicing Hyperledger. This is one of the top listed blockchains. This architecture follows R3 Corda specifications. Sharing the interview questions with you that I have prepared for my interview.

Though Ethereum leads in the real-time applications. The latest Hyperledger version is now ready for production applications. It has now become stable for production applications.
The Hyperledger now backed by IBM. But, it is still an open source. These interview questions help you to read quickly. The below set of interview questions help you like a tutorial on Hyperledger fabric. Hyperledger Fabric Interview Questions1). What are Nodes?
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…

Hadoop fs (File System) Commands List

Image
List of basic Hadoop fs File system commands given in this post. These are handy commands. Basically, you always need to remember. 👍





The Syntax for Command and the List and Usage.
Hadoop fs -cmd <args>

👉 cmd is a specific command and arg is the variable name. 

cat

Hadoop fs –cat FILE [FILE …]

👉 Displays the files' content. For reading compressed files.


chgrp

Hadoop fs –chgrp [-R] GROUP PATH [PATH …]

👉 Changes the group association for files and directories. The – R option applies the change recursively. The user must be the files' owner or a superuser.


chmod

Hadoop fs –chmod [-R] MODE[,MODE …] PATH [PATH …]

👉 Changes the permissions of files and directories. Like, its Unix equivalent, MODE can be a 3-digit octal mode, or {augo}+/-{rwxX}. The -R option applies the change recursively. The user must be the files' owner or a superuser.


chown


Hadoop fs –chown [-R] [OWNER][:[GROUP]] PATH [PATH…] 
👉 Changes the ownership of files and directories. The –R option applies th…

Python Dictionary Vs List Both Not The Same Why

Image
Dictionary and List we use interchangeably in Python to store values. For beginners, both look the same. In reality, they both differ. I want to share some key differences between Dictionary and List.





👉 Dictionary Vs List Top Differences
Values in lists are accessed by means of integers called indices, which indicate where in the list a given value is found.
Dictionaries access values by means of integers, strings, or other Python objects called keys, which indicate where in the dictionary a given value is found. 
In other words, both lists and dictionaries provide indexed access to arbitrary values, but the set of items that can be used as dictionary indices is much larger than, and contains, the set of items that can be used as list indices. 
Also, the mechanism that dictionaries use to provide indexed access is quite different from that used by lists.
Both lists and dictionaries can store objects of any type.
Values stored in a list are implicitly ordered by their positions in the list b…

How to use Blockchain on Cloud

Image
Blockchain applications are growing in the financial world. Security is the main motto behind blockchain applications. You cannot tamper a record once created.


What is a platform
A platform is a place where you can develop applications.
Top Blockchain Cloud Platforms The development needs to create a project and deploy it into production. So that the real use can feel by users at their end.
Ok...

Let us come to three popular cloud platforms that are highly used in Blockchain applications:
HyperLedgerIBM BlueMixMicrosoft Azure
#1. HyperLedgerThe Hyperledger project is led by Executive Director Brian Behlendorf, who has decades of experience dating back to the original Linux Foundation and Apache Foundation, as well as being a CTO of the World Economic Forum. So it's not surprising that Hyperledger has been well received. You can learn hyper Ledger here.
Many of the top business and industry leaders have joined the project, including Accenture, Cisco, Fujitsu Limited, IBM, Intel, J.P. Mo…
