Blockchain Smart contract behind mechanism you need to learn quickly

Image
By
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 Smart Contract of Blockchain.

Smart Contract Mechanism

What is Smart Contract

  • A 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 physical contract into computing world, you can say as smart contract
  • Blockchain supports you to create smart contracts.
  • Smart Contracts are self-executing programs which run on the blockchain and are capable of enforcing rules
  • Using Blockchain as 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 Contract

  1. Currently smart contracts are being used only in Crypto Currencies
  2. Now Smart Contracts being used in all financial transactions
  3. Smart contract can then raise funds for the foundation to complete a certain objective
  4. Primary benefit is to avoid middle men and to avoid fraud and cheating in the business world

Smart Contract Based Markets

Smart markets

When Smart Contract Initiated

  • Smart contracts are self executed programs. So they run automatically whenever they need. 
  • Each Smart contract in Blockchain stored in a Block.
  • Smart contracts have the following capabilities-self-execute, self-verify, self-enforce and self-constrain the agreement between two parties.

How many smart contract are present in Blockchain

  1. You can create 'N' number of smart contracts in Blockchain
  2. Smart Contract Manger over see all the transactions created in a network such that it avoids any fraud or cheating.

Summary

The contracts created under blockchain platform you can say as smart contract. The legality of contract monitored by computers but not by human beings. They enforce rules and creates alerts when something went wrong.

Python Syntax Rules Eliminate Errors Before you start debugging

By
In Python, if you know syntax rules, you can eliminate errors. The basic mistakes programmers do are missing semicolons, adding extra commas, and extra spaces. Python is case sensitive. So using the wrong identifier gives an error.
Indentation is unique to Python. You cannot find this kind of rule in any other programming languages Python Syntax Cheat Sheet These are the main areas you need to focus while writing a Python program. You need to learn rules. Else you need to waste a lot of time fixing the issues or errors.
Indentation or Syntax ErrorsExceptionsHandling Exceptions
1. Indentation If you do not follow proper order, you will get an error. The details of one block shroud follow in one vertical line. The sub-block should be inside of that.

In if loop, the if, elif, and else should have same indentation. Not only, the statement inside of them should have same indentation.Understand these examples a good material on indentation for you.   2. Exceptions  Python raises exception, wh…

Python Improved Logic Easy Way to Calculate Factorial

By
I am practicing Python programming. This post is you can write logic to calculate factorial in function. This function you can call it a user-defined function. The function name is 'factorial.py'. In real-time, you can write a program in a file and run it in python console. The main task of a developer is to create functions for the reusable code. They call these functions whenever they need. Factorial calculation program for supplied input value. Factorial Logic in Python I have completed this logic in 3 steps. Write factorial.pyImportExecute it Write Factorial.py  Here you need to define a function. Use 2 for loops, and write your logic. This is done on LInux operating system. You can also try on Linux.
After, ESC command Use, :wq to come out of the module. Import Factorial.py Go to Python console, using 'python' command. Use import factorial.py command.


Execute Factorial.py  >>> factorial.fact(5) It will show the result of factorial. Bottom line  Factorial o…

Calculate Circle Area the Logic You Need to write in Python

By
In Python, you can calculate circle area easily by using function. The purpose of Python is to use in data analysis.


You need this logic in many areas. You can use in your present finance projects or new ones.

Benefits of function you can re-use the same code number of times Area of Circle=pi*r*r Area of Circle Steps Given - You Can do Using Two Methods, Explained Both Methods I have given steps to calculate area of circle using two different methods. First I followed by creating an user defined function. Next directly I ran  the formula in interpreter.


Method-1 Steps I have followed to Calculate Area Using FunctionLogged into Cent Os (Linux) Create .py module Import .py module into Python Execute .py module  1. Log in I have first logged into CentOS. You can see there '$'.

2. Creating .py module To create .py module. You can use vi editor command.

You need 'import decimal' to get Decimal values. Else you will get only integer.

Top 10 SCALA Quiz Questions for Programmers

By
Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do.


To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them. There’s a REPL and IDE worksheets for quick feedback.

Developers like it so much that Scala won the ScriptBowl contest at the 2012 JavaOne conference. At the same time, Scala is the preferred workhorse language for many mission critical server systems. The generated code is on a par with Java’s and its precise typing means that many problems are caught at compile-time rather than after deployment.


At the root, the language’s scalability is the result of a careful integration of object-oriented and functional language concepts.(Ref-what is Scala).View Su…

Automation developer these are top Skills you need to learn

By
Robotic process automation is an upcoming IT skill. Three tools are popular. It is difficult to learn all three tool. So, learn anyone tool to start your career in automation.
To get a job in this line, I found in my research that some programming skills and Hand-on training on any one of the tools is required. Also, try to know the differences between popular RPA tools.
Skills Companies Looking in Automation Engineers All big companies looking for candidates having experience in Automation anywhere, Blue Prism and UIPath. It is not possible to learn all tools. Learn anyone tool and do practice well.

Ok.

You may ask a question about how to do it. Join in good training institute and learn one tool.  Take online classes to learn faster.

To learn Uipath try here. Also, you can enroll online course to learn UiPath.
