What is a cryptocurrency?
Cryptocurrency is digital money that works online. It’s like regular money, but it exists only on the internet. Instead of coins or bills that you can hold, it’s stored in digital wallets on computers or smartphones.
What makes cryptocurrency special is that it doesn’t belong to any government or bank. It uses advanced technology called cryptography to keep transactions secure. This means it’s harder for people to steal or cheat with cryptocurrency.
You can use cryptocurrency to buy things online or send it to other people. Each transaction is recorded on a special database called a blockchain, which keeps everything transparent and safe.
The most famous cryptocurrency is Bitcoin, but there are many others too, each with its own special features and uses.
What is virtual currency?
Virtual currency is a type of digital money that is used in online environments like games or virtual worlds. It’s not physical money, but it can be used to buy things or access special features within those digital spaces. Virtual currencies are created and managed by private companies, not governments. They only have value within the specific online community or platform where they are used and can’t be used for regular purchases in the real world. It’s different from cryptocurrencies like Bitcoin, which are digital currencies that can be used for transactions online and sometimes in the real world too.
What is blockchain?
Blockchain is a special kind of technology that helps keep track of information securely and transparently. Instead of storing data in one central place, it is spread across many computers connected in a network. When new information is added, it forms a “block” that is linked to the previous ones, creating a chain. This makes it difficult to change or cheat the system.
Blockchain was first used for cryptocurrencies like Bitcoin, but it has other uses too. It can help with things like tracking products in a supply chain, making sure contracts are followed, or even voting in elections. It’s like a digital record book that everyone can see and trust, without needing a middleman.
What is distributed ledger Technology?
Distributed Ledger Technology (DLT) is a system that stores and manages records or transactions in a secure and decentralized way. Instead of having one central authority, many participants or computers keep copies of the records. They work together to verify and update the information. DLT ensures transparency, reduces the need for middlemen, and makes it harder to tamper with the data. It provides a trustworthy and auditable record of transactions. Blockchain is one type of DLT, but there are others like directed acyclic graphs (DAGs). DLT can be used in various industries such as supply chain, healthcare, finance, and identity verification to keep track of information in a reliable and transparent manner.
What is cryptography?
Cryptography is a way of protecting information by turning it into secret code. It uses special math techniques and keys to scramble data, making it unreadable to unauthorized people. This process is called encryption. The encrypted data is called ciphertext. To make it readable again, the ciphertext is transformed back into the original form, called plaintext, using decryption and the right keys.
Cryptography is important for keeping sensitive information safe, like passwords, credit card numbers, or private messages. It is used in many areas, like online security, banking, and communication. By using cryptography, only the intended recipient can unlock and understand the information, while others cannot access or understand it. It helps ensure privacy and protects against unauthorized access or tampering.
