  • BNB
  • USD Coin
  • Ripple and many more.

These digital assets have gained immense popularity over recent years due to their potential to revolutionize traditional financial systems and create new opportunities for investors. For more details, please check Cryptocurrencies.

What is Cryptography?

The word Crypto in cryptocurrency came from Cryptography, so you may be wondering what is this cryptography?

In the context of cryptocurrencies, cryptography refers to the use of mathematical algorithms to secure and verify transactions on the blockchain. Cryptography is used to create digital signatures that prove ownership of the cryptocurrency and to secure transactions by ensuring that they cannot be altered. It is a key element of the decentralized and trustless nature of cryptocurrencies, providing security and immutability to the system.

Check below diagram to understand the role of cryptography in cryptocurrencies:

graph LR
A[Cryptographic Algorithm] --> B[Digital Signature]
A --> C[Hash Function]
B --> D[Verify Transaction]
C --> D
Figure: Cryptography

In the above diagram, the cryptographic algorithm is used to generate a digital signature that proves ownership of the cryptocurrency. The hash function is used to create a unique digital fingerprint of the transaction data, which is then verified by the digital signature. This ensures that the transaction is valid and cannot be altered.

What is an Algorithm?

An algorithm is a step-by-step procedure for performing calculations, data processing, or automated reasoning. Generally, you can think of an algorithm as a set of instructions or rules designed to perform a specific task or solve a particular problem.

What is Blockchain?

Blockchain is a decentralized, distributed digital ledger that records transactions in a secure and transparent manner. It is essentially a database that stores transactional data in blocks that are linked together in a chain. Each block contains a record of multiple transactions, and once a block is added to the chain, it cannot be altered or deleted.

What is Crypto Mining?

The basic concept of mining is similar for most cryptocurrencies, but the specific mining process can vary depending on the cryptocurrency. Each cryptocurrency has its own consensus algorithm, which determines how transactions are validated, and new coins are created. Some cryptocurrencies use proof-of-work (PoW) consensus algorithms, like Bitcoin and Ethereum, which involve solving complex mathematical problems to validate transactions and create new coins. Other cryptocurrencies use proof-of-stake (PoS) or other consensus algorithms, which involve validators staking or locking up their coins to secure the network and validate transactions. Therefore, the specific mining process can vary depending on the cryptocurrency and the consensus algorithm it uses.

What is Consensus Algorithm?

A Consensus algorithm is a protocol or a set of rules that ensure that all nodes (computers) in a decentralized network agree on the current state of the network and the validity of transactions. In other words, a consensus algorithm is used to validate transactions and create new blocks in a blockchain network in a decentralized way. The goal of a consensus algorithm is to prevent fraudulent transactions and double-spending and to ensure that the network remains secure and reliable.

Types of Consensus Algorithms

There are several different types of consensus algorithms, including Proof of Work (PoW), Proof of Stake (PoS), Delegated Proof of Stake (DPoS), Proof of Authority (PoA), Byzantine Fault Tolerance (BFT), and Hybrid consensus algorithms. Each algorithm has its own unique features, advantages, and disadvantages, and is designed to suit the specific needs and goals of the cryptocurrency network it powers.

Proof of Work (PoW)

In PoW, miners compete to solve complex mathematical puzzles in order to validate transactions and add new blocks to the blockchain. This requires significant computational power and energy consumption.

A[Pow] --> B[Miners]
B --> C[Solve Complex Mathematical Puzzles]
C --> D[Validate Transactions]
D --> E[Add Blocks to the Blockchain]
F[Significant Computational Power and Energy Consumption] --> C
Figure: PoW

Proof of Stake (PoS)

In PoS, validators are chosen based on the amount of cryptocurrency they hold and are willing to “stake” or “lock up” as collateral. Validators are then chosen randomly to validate transactions and create new blocks, and earn rewards based on their stake.

A[PoS] --> B[Validators chosen based on cryptocurrency holdings];
B --> C["Validators stake or lock up cryptocurrency as collateral"];
C --> D["Validators chosen randomly to validate transactions and create new blocks"];
D --> E["Validators earn rewards based on their stake"];

Figure: PoS

Delegated Proof of Stake (DPoS)

DPoS is similar to PoS, but validators are chosen by coin holders who vote for delegates to validate transactions on their behalf. Validators are compensated based on the number of votes they receive.

A[DPoS] -->|Validators Chosen by Vote| B[Coin Holders];
B -->|Vote for Delegates| C[Validators];
C -->|Validate Transactions| D[Add Blocks to Blockchain];
D -->|Compensation based on Votes| E[Validators];
Figure: DPoS

Proof of Authority (PoA)

In PoA, validators are chosen based on their identity and reputation rather than their computational power or stake. Validators are responsible for validating transactions and creating new blocks and are compensated for their services.

graph TD
A[PoA] --> B[Validators]
B --> C[Identity and Reputation]
B --> D[Validate Transactions and Create New Blocks]
B --> E[Compensation for Services]
Figure: PoA

Byzantine Fault Tolerance (BFT)

BFT is a consensus algorithm used in permissioned blockchains where validators are known and trusted. Validators work together to validate transactions and create new blocks, and must agree on the validity of each transaction before it is added to the blockchain.

A[Blockchain] --> B[Validators]
B --> C[Validate transactions]

D --> E[Add blocks to blockchain]
E --> F{Reach consensus}
F -->|Yes| G[Transaction is added to blockchain]
F -->|No| H[Validators try again]
H --> C

Figure: BFT

Hybrid Consensus Algorithms

Some cryptocurrencies use a combination of different consensus algorithms to achieve a balance between security, scalability, and energy efficiency. Such algorithms are called hybrid consensus algorithms.

What are Smart Contracts?

Smart contracts are self-executing computer programs that automatically enforce the terms of a contract between parties without the need for intermediaries like lawyers or banks. They are built on blockchain technology and can be used to manage a wide range of transactions and agreements in a transparent, secure, and decentralized way. Smart contracts are designed to be tamper-proof, reliable, and can only execute when all the conditions coded into them are met.

Coin vs Token

In terms of cryptocurrency, when we talk about coin vs token, the main difference between a coin and a token is that a coin is a cryptocurrency that operates on its own blockchain, while a token is a cryptocurrency that operates on an existing blockchain platform. Coins are designed to be used as a form of currency, while tokens can represent anything from digital assets to loyalty points. Additionally, coins are typically mineable, while tokens are usually created through smart contracts.

A --> D[Mineable]

E[Token] --> F[Operates on existing blockchain platform]
E --> G[Can represent anything from digital assets to loyalty points]
E --> H[Created through smart contracts]
Figure: Coin vs Token

What is a Decentralized Application (dApp)?

A dApp is a software application that operates on a decentralized network like a blockchain, making it transparent, secure, and autonomous. It uses smart contracts to enforce rules and can be used for a variety of purposes like financial transactions, identity verification, and gaming. The goal is to create a more transparent and decentralized alternative to traditional centralized applications.

CryptoKitties and IDEX are the most popular examples of dApps where CryptoKitties is a blockchain game and IDEX is a decentralized exchange where users trade crypto tokens on Ethereum.

What is a Crypto Wallet?

A cryptocurrency wallet is a digital software application that allows users to securely store, send, and receive digital assets, such as Bitcoin, Ethereum, and other cryptocurrencies.
