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

It introduced a novel idea set out in a white paper by the mysterious Satoshi Nakamoto—bitcoin offers the promise of an online currency that is secured without any central authority, unlike government-issued currencies. There are no physical bitcoins, only balances associated with a cryptographically secured public ledger. Although bitcoin was not the first attempts at an online currency of this type, it was the most successful in its early efforts, and it has come to be known as a predecessor in some way to virtually all cryptocurrencies which have been developed over the past decade.1bitcoin зарегистрироваться cryptocurrency dash bitcoin c анимация bitcoin alpha bitcoin 99 bitcoin bitcoin ocean майнер ethereum xpub bitcoin Think about how you spend your money in everyday life.

In practical application, the distribution of ownership shifts dramatically, heavily favoring the holders of financial assets (which is what the Fed buys in the process of creating new dollars) as well as those with cheap access to credit (the government, large corporations, high net-worth individuals, etc.). In aggregate, the purchasing power of every dollar declines, just not immediately, while a small subset benefits at the cost of the whole (see the Cantillon Effect). Despite the consequences, the Fed takes these actions in an attempt to support a credit system that would otherwise collapse without the supply of more dollars. In the Fed’s economy, the credit system is the price setting mechanism as the amount of dollar-denominated debt far outstrips the supply of dollars, which is also why the purchasing power of each dollar does not immediately respond to the increase in the money supply.Power Splitters.Bitcoin use something called SHA-256 hashing.форк bitcoin майнер ethereum
