1. Cryptocurrency and blockchain-based payment system


Working of blockchain-based payment system

  • A blockchain-based payment system is a decentralized payment system facilitating payment messaging, clearing, and settlement for cross-border fiat and digital currency transactions in a single network.
  • Blockchain-based payment systems are essentially a method of making payments with the help of blockchain technology that facilitates fast, secure, low-cost international payment processing services through the use of encrypted distributed ledgers that provide trusted real-time verification of transactions without the need for intermediaries such as correspondent banks and clearinghouses.
  • Some advantages of blockchain-based payments include the elimination of Intermediaries, transparency, safe and faster cross-border payments, and automation with smart contracts.

2. Major cryptocurrencies and their comparison

  • According to CoinMarketCap, the top 3 cryptocurrencies by market capitalization are Bitcoin, Ethereum, and Cardano.


  • Bitcoin was the first and is currently the most popular cryptocurrency that was invented in the year 2009 by an unknown person or group of people using the name Satoshi Nakamoto.
  • According to CoinMarketpCap, it is the largest cryptocurrency measured by market capitalization and the amount of data stored on its blockchain.

  • Cardano (ADA) is the third-largest cryptocurrency by market capitalization and is a fully open-source, decentralized public blockchain and cryptocurrency.
  • It combines ground-breaking technologies to provide unparalleled security and sustainability to decentralized applications, systems, and societies.
  • It is considered to be the most reliable cryptocurrency through the use of the Proof of stake (PoS) algorithm, which results in eliminating the requirement for extra machines within the system as the nodes will be responsible for throughput, and the system will be less vulnerable to interference as a result.

Bitcoin vs Ethereum

However, Cardano is considered to be the third generation technology, specifically designed with the aim of offering all the necessary functionality while overcoming the problems faced by other cryptocurrencies.
