Project Overview: What is a cryptocurrency?

A cryptocurrency is a digital asset issued on a blockchain, used as:

A medium of exchange (payments, cross-border transfers)
A store of value (like Bitcoin)
A unit of account in decentralized applications (DeFi, Web3 games)
A utility token to access services

Popular cryptocurrencies include Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Cardano (ADA), and Toncoin (TON). Each is based on its own protocol and vision.

Technical Overview: How cryptocurrencies work

Cryptocurrencies are built on several core technologies:

The blockchain

A decentralized, tamper-proof ledger where each transaction is time-stamped and validated by consensus.

Consensus mechanisms

Depending on the project, validation is done via:

Proof of Work (PoW) – e.g. Bitcoin, energy-intensive but secure.
Proof of Stake (PoS) – e.g. Ethereum 2.0, more energy-efficient.
Others: Proof of History, DPoS – for scalability or speed.

Smart contracts

Self-executing programs on blockchains like Ethereum, enabling DeFi, NFTs, and DAOs. Tokens They may be:

Native (like BTC or ETH)
Secondary (e.g., ERC-20 on Ethereum, SPL on Solana), granting rights within a specific ecosystem

Historical context and origins

The cryptocurrency concept began in 2008, when Satoshi Nakamoto released the Bitcoin whitepaper. Its goal: to create a peer-to-peer payment system without trusted third parties. Since then:

2015: Ethereum introduces smart contracts
2017: ICO boom
2020: DeFi surge
2021–2023: Mass adoption followed by market corrections
2024 onward: Regulation, real-world use cases, scalability

Key features and use cases of cryptocurrencies

Cryptocurrencies are not just speculation tools. Their applications are wide-ranging and constantly evolving:

International payments

Fast, low-cost transfers without banks (e.g., with USDT/USDC stablecoins)

Decentralized Finance (DeFi)

Lending, borrowing, automated yield via protocols like Aave, Maker, Curve

Gaming and metaverse

Tokens integrated into Web3 games like Axie Infinity, Decentraland, or The Sandbox

NFTs & digital identity

Ownership, collectibles, and rights management on-chain

Hedge against inflation

In some countries, Bitcoin is seen as a store of value versus fiat currencies
