Blockchain Smart Contract The Perfect Example

-
The smart contract in Blockchain is a software application that works without human intervention. Here I have shared the Smart Contract backend process.

Smart Contract Mechanism.

1. What is Smart Contract

  • A smart contract is a protocol that 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 contract
  • Blockchain supports you to create smart contracts.
  • Smart Contracts are self-executing programs that run on the blockchain and are capable of enforcing rules
  • Using Blockchain as a platform and making an agreement or contract between more than two parties, you can say as Smart Contract.

2. Traditional Markets 

Blockchain Smart Contract

3. 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. A smart contract can then raise funds for the foundation to complete a certain objective
  4. The primary benefit is to avoid middlemen and to avoid fraud and cheating in the business world

4. Smart Contract-Based Markets

5. When Smart Contract Initiated

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

6. How many smart contracts are present in Blockchain

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

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

 In the world of data science, automation, and general programming, working with files is unavoidable. Whether you’re dealing with CSV reports, JSON APIs, Excel sheets, or text logs, Python provides rich and easy-to-use libraries for reading different file formats. In this guide, we’ll explore how to read different files in Python , with code examples and best practices. 1. Reading Text Files ( .txt ) Text files are the simplest form of files. Python’s built-in open() function handles them effortlessly. Example: # Open and read a text file with open ( "sample.txt" , "r" ) as file: content = file.read() print (content) Explanation: "r" mode means read . with open() automatically closes the file when done. Best Practice: Always use with to handle files to avoid memory leaks. 2. Reading CSV Files ( .csv ) CSV files are widely used for storing tabular data. Python has a built-in csv module and a powerful pandas library. Using cs...

SQL Query: 3 Methods for Calculating Cumulative SUM

-
Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...
