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

High levels of hardware draw are reflected in a low barrier to entry for 'joiners' who seek to build a service on top of the network, use a wallet application, or run a full node; they can do so without needing to purchase or configure specialized hardware. More joiner activity means more 'eyeballs' on the network, increasing stability and therefore developer draw, and begetting a virtuous cycle.tether верификация bitcoin agario The Mt.Gox liquidity problems. When the biggest exchange Mt.Gox suspended bitcoin and fiat withdrawals without a possibility of refunding due to backend evaluation and repairs, bitcoin price declined sharply. The bitcoin value cratered following the mass media announcements.

As more miners upgrade, the chain with predominantly new blocks becomes the longest, which would further orphan old version blocks, which would lead to more miners upgrading, and the system self-corrects. Since new version blocks are accepted by both old and upgraded nodes, the new version blocks eventually win.кошельки bitcoin bitcoin страна пулы bitcoin bitcoin хешрейт сайте bitcoin bitcoin double tradingview bitcoin hyip bitcoin клиент bitcoin bitcoin бот cryptonight monero
