What is Cryptocurrency?

Cryptocurrency is a virtual cash that uses cryptography for security. Unlike standard currencies, such as the US dollar or the euro, cryptocurrencies are decentralized and typically operate on blockchain.

Blockchain Technology

The Ledger

At the heart of cryptocurrency is the blockchain, which can be thought of as a public ledger. This ledger records all transactions made with a particular cryptocurrency. It’s distributed across a network of computers, making it nearly impossible to tamper with.


One of the main features of blockchain is its decentralization. Cryptocurrencies operate on a peer-to-peer network, unlike traditional banks or governments that control traditional currencies. This means no single entity has control over the currency.


Miners use solid computers to solve complex mathematical problems to secure the network and validate transactions. In return for their efforts, they are rewarded with cryptocurrency coins.

How do Transactions work?


Digital Wallets

You need a digital wallet to send, receive, and store cryptocurrencies. These wallets come in various forms, such as software, hardware, or paper wallets. Each wallet has a public and private keys (like a password).

Sending Cryptocurrency

When you want to send cryptocurrency to someone, you initiate a transaction by signing it with your private key. The deal is then broadcast to the network, where miners validate and record it on the blockchain.


Once a transaction is included in a block on the blockchain, it receives confirmations. The more proofs, the more secure the transaction becomes. Typically, you’ll need to wait for a few confirmations before considering a transaction final.
