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

As it turns out, that analogy isn’t too far off.An analogy is that a cryptocurrency is like a social network, except instead of being about self-expression, it’s about storing and transmitting value. It’s not hard to set up a new social network website; the code to do it is well understood at this point. Anyone can make one. However, creating the next Facebook (FB) or other billion-user network is a nearly impossible challenge, and a multi-billion-dollar reward awaits any team that somehow pulls it off. This is because a functioning social network website without users or trust or uniqueness, is worthless. The more people that use one, the more people it attracts, in a self-reinforcing virtuous network effect, and this makes it more and more valuable over time.With the rollercoaster volatility of Bitcoin and other cryptocurrencies, it canIn Eastern philosophy, the kinship of zero and infinity made sense: only in a state of absolute nothingness can possibility become infinite. Buddhist logic insists that everything is endlessly intertwined: a vast causal network in which all is inexorably interlinked, such that no single thing can truly be considered independent — as having its own isolated, non-interdependent essence. In this view, interrelation is the sole source of substantiation. Fundamental to their teachings, this truth is what Buddhists call dependent co-origination, meaning that all things depend on one another. The only exception to this truth is nirvana: liberation from the endless cycles of reincarnation. In Buddhism, the only pathway to nirvana is through pure emptinessmonero обмен bitcoin price crococoin bitcoin vizit bitcoin casinos bitcoin bitcoin rub bitcoin мошенничество ruble bitcoin порт bitcoin ethereum news bitcoin автосерфинг trade cryptocurrency maps bitcoin bitcoin antminer ethereum chart strategy bitcoin bitcoin talk
Supply and DemandA private key and a Bitcoin address were primary needed in order for you to send Bitcoins. Hence, Bitcoin address is randomly generated and it is compose of letters and numbers. On the other hand, you will be keeping the private key because it is different from Bitcoin address in purpose. Private keys are also compose of numbers and letters.mine monero ethereum ethash

Instead, it serves the purpose of efficiently ensuring that the data has not been tampered with. Change even one number in an arbitrarily long string of transactions, and the hash will come out unrecognizably different. Since every block contains the previous block's hash, the network can know instantly if someone has tried to insert a bogus transaction anywhere into the ledger, without having to comb through it in its entirety every 2.5 minutes. ethereum 1070 шифрование bitcoin
