Crypto is a short form for cryptography. It is the practice of secure communication in the presence of third parties. Cryptography is used in a variety of applications, including email, file sharing, and secure communications.Crypto is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. A defining feature of a cryptocurrency, and arguably its biggest allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control. The decentralized nature of cryptocurrency ledgers makes cryptocurrencies less vulnerable to fraud or theft.
Bitcoin, the first and most well-known cryptocurrency, was created in 2009. Since then, numerous other cryptocurrencies have been created. These are often called altcoins, as a contraction of “bitcoin alternative.”
Cryptocurrencies are often traded on decentralized exchanges and can also be used to purchase goods or services. Bitcoin, for example, can be used to book hotels on Expedia, shop for furniture on Overstock and buy Xbox games. However, bitcoin’s most important characteristic, and the thing that makes it different from traditional currencies, is that it is decentralized. No single institution controls the bitcoin network. This puts some people at ease, because it means that a large bank can’t control their money.

What is blockchain?
A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
What is mining?
Mining is how new Bitcoin and other cryptocurrency are created. Miners are rewarded with cryptocurrency for verifying and committing transactions to the blockchain. Ethereum miners are rewarded based on their share of work done, rather than their share of the total number of blocks mined.
