Crypto! Crypto! Crypto! # What is the cryptocurrency? In the running world where ever you go. you can hear this sound crypto or cryptocurrency. If you ask any one 95% people says don't know. 4% or above said digital currency means BITCOIN or NETELLER or Skrill etc. and rest of % , less than 1% or .10 % actually knows about cryptocurrency. believe it or not, 90% of those knowledgeable person who actually know about cryptocurrency are not to ready to share this other person. rest of 10% ready to share it whole world. I respect them. Now a days world became small by technology. you can find definition of cryptocurrency though internet. but it is not at all knowledge. Today i am going to tell you about cryptocurrency in my little knowledge. Now see the begging history of cryptocurrency Since 1983, One American cryptographer, name David Chaum. He conceived an pseudonym cryptographic electronic money, and called it e-cash. after 12 years in 1995, he implement it. and named Digicash. This is the Starting path of cryptocurrency In the following years, 1996,1997, 1998, its activities increased day by day. at last the result came out in 2009, first decentralized cryptocurrency, bitcoin, was created by using Hash function SHA-256. This is the breakthrough invention created by Satoshi Nakamoto. ### What is cryptocurrency? cryptocurrency is best thought of digital currency for the digital age. cryptocurrency is similar to regular money — think $ or € . it used cryptographical functions and conduct financial transactions. but, it’s only digital, So, here is no money or coins to carry out. > Formal definition of Cryptocurrency According to Jan Lansky, a cryptocurrency is a system that meets six conditions: - The system does not require a central authority, its state is maintained through distributed consensus. - The system keeps an overview of cryptocurrency units and their ownership. - The system defines whether new cryptocurrency units can be created. If new cryptocurrency units can be created, the system defines the circumstances of their origin and how to determine the ownership of these new units. - Ownership of cryptocurrency units can be proved exclusively cryptographically. - The system allows transactions to be performed in which ownership of the cryptographic units is changed. A transaction statement can only be issued by an entity proving the current ownership of these units. - If two different instructions for changing the ownership of the same cryptographic units are simultaneously entered, the system performs at most one of them.

It’s completely decentralized with no server or central authority. – Satoshi Nakamoto, 09 January 2009, announcing Bitcoin on SourceForge. _{[Source](https://blockgeeks.com/guides/what-is-cryptocurrency/)} ![cr3.jpg](https://cdn.steemitimages.com/DQmYQj4xP9XbSskJQDRTph38EaC6VtmnoLayjBLAS6qSZwD/cr3.jpg) _{[Image source](https://blockgeeks.com/guides/what-is-cryptocurrency/)} Transactions are sent between peers using software called “cryptocurrency wallets.” The person creating the transaction uses the wallet software to transfer balances from one account (AKA a public address) to another. To transfer funds, knowledge of a password (AKA a private key) associated with the account is needed. Transactions made between peers are encrypted and then broadcast to the cryptocurrency’s network and queued up to be added to the public ledger. Transactions are then recorded on the public ledger via a process called “mining” (explained below). All users of a given cryptocurrency have access to the ledger if they choose to access it, for example by downloading and running a copy of the software called a “full node” wallet (as opposed to holding their coins in a third party wallet like Coinbase). The transaction amounts are public, but who sent the transaction is encrypted (transactions are pseudo-anonymous). Each transaction leads back to a unique set of keys. Whoever owns a set of keys, owns the amount of cryptocurrency associated with those keys (just like whoever owns a bank account owns the money in it). Many transactions are added to a ledger at once. These “blocks” of transactions are added sequentially by miners. That is why the ledger and the technology behind it are called “block” “chain.” It is a “chain” of “blocks” of transactions. TIP: I’ve just described how Bitcion works and how many other coins work too. However, some altcoins use unique mechanics. For example some coins offer fully private transactions and some don’t use blockchain at all. Source of this information

Ethereum (ETH) – It introduced smart contracts to the blockchain. It processes transactions quickly and inexpensively and runs smart contracts. 3. Ripple (XRP) – Ripple aims to improve the speed of financial transactions. It is considered one of the biggest cryptocurrencies in the world as it currently comprises of more than 150 people. 4. Stellar lumens (XLM) – This network uses blockchain to speed up international payments for a small transaction fee. 5. Bitcoin Cash (BCH) – It enabled the block size to be increased from 1 MB to 8 MB. Its goal is to increase the number of transactions. 6. EOS – While ethereum involves a fee for every interaction or modification with the network, the DAPP (Decentralized app) creator foots the bill, and the user doesn’t pay anything. 7. LiteCoin (LTC ) – It is a peer-to-peer platform designed to handle a larger number of transactions for a lower cost. 8. Cardano (ADA) – It focuses on interoperation with other cryptocurrencies by fixing issues such as scalability and democratized voting. 9. Monero (XMR) – It implements cryptonic hashing of receiving address thereby separating the coin from the address it is going to. 10. Tether (UDST) – It aims to fix legal issues and protects people from market volatility. 11. Dash (DASH) – Short for digital cash, it instantly sends funds through double-send-proof security. 12. TRON (TRX) – It enables users to freely publish, store, and own data thereby vesting them with the power to decide where and how to share. 13. NEO – It aims to digitize many types of assets and aims to make it possible for use in smart contracts. 14. Binance Coin (BNB) – It uses its cryptocurrency platform, Binance, to process 1.4 million orders per second. 15.
