What is cryptocurrency?
If you take away all the noise around cryptocurrencies and reduce it to a simple definition, you find it to be just limited entries in a database no one can change without fulfilling specific conditions. This may seem ordinary, but, believe it or not: this is exactly how you can define a currency.
Take the money on your bank account: What is it more than entries in a database that can only be changed under specific conditions? You can even take physical coins and notes: What are they else than limited entries in a public physical database that can only be changed if you match the condition than you physically own the coins and notes? Money is all about a verified entry in some kind of database of accounts, balances, and transactions.
So, to give a proper definition – Cryptocurrency is an internet-based medium of exchange which uses cryptographical functions to conduct financial transactions. Cryptocurrencies leverage blockchain technology to gain decentralization, transparency, and immutability.
How miners create coins and confirm transactions
Let‘s have a look at the mechanism ruling the databases of cryptocurrencies. A cryptocurrency like Bitcoin consists of a network of peers. Every peer has a record of the complete history of all transactions and thus of the balance of every account.
A transaction is a file that says, “Bob gives X Bitcoin to Alice“ and is signed by Bob‘s private key. It‘s basic public key cryptography, nothing special at all. After signed, a transaction is broadcasted in the network, sent from one peer to every other peer. This is basic p2p-technology.

Blockchain and Cryptocurrency
The transaction is known almost immediately by the whole network. But only after a specific amount of time it gets confirmed.
Confirmation is a critical concept in cryptocurrencies. You could say that cryptocurrencies are all about confirmation.
As long as a transaction is unconfirmed, it is pending and can be forged. When a transaction is confirmed, it is set in stone. It is no longer forgeable, it can‘t be reversed, it is part of an immutable record of historical transactions: of the so-called blockchain.
Only miners can confirm transactions. This is their job in a cryptocurrency-network. They take transactions, stamp them as legit and spread them in the network. After a transaction is confirmed by a miner, every node has to add it to its database. It has become part of the blockchain.
For this job, the miners get rewarded with a token of the cryptocurrency, for example with Bitcoins. Since the miner‘s activity is the single most important part of the cryptocurrency-system we should stay for a moment and take a deeper look at it.
caleb-chen: What is Ethereum“In the next few years, we are going to see national governments take large steps towards instituting a cashless society where people transact using centralized digital currencies. Simultaneously, the decentralized cryptocurrencies – that some even view as harder money – will see increased use from all sectors.” – Caleb Chen London Trust Media

While litecoin requires more sophisticated technology to mine than bitcoin, blocks are actually generated up to four times faster. Litecoin also processes financial transactions a lot quicker, and can also process a higher number of them over the same time period.They can also work as a safe and stable way to save money, like a traditional savings account.Getting Bitcoin blockchain explained is essential to understanding how blockchain works. The Bitcoin blockchain is a database (known as a 'ledger') that consists only of Bitcoin transaction records. There is no central location that holds the database, instead, it is shared across a huge network of computers. So, for new transactions to be added to the database, the nodes must agree that the transaction is real and valid.captcha bitcoin Cryptocurrencies such as Bitcoin, Dash, Ethereum and Monero offer a certain level of anonymity to users. Why? Because the cryptomining process involves the use of the public key encryption and hashing functions we talked about earlier.wifi tether ethereum dark hosting bitcoin bitcoin часы
