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

Zero punched a hole and created a vacuum in the framework of mathematics and shattered Aristotelean philosophy, on which the power of The Church was premised. Today, Bitcoin is punching a hole and creating a vacuum in the market for money; it is killing Keynesian economics—which is the propagandistic power-base of the nation-state (along with its apparatus of theft: the central bank).Miners are like the record-keepers of Ethereum – they check and prove that no one is cheating. Miners who do this work are also rewarded with small amounts of newly-issued ETH.ethereum metropolis uk bitcoin tether пополнение monero купить metal bitcoin ethereum пул bitcoin etf

Monero uses the past median in the blocksize as one of the components to dynamically increase and decrease the cap on the block size.Dynamic block size prevents congestion if the network usage increases, providing room to scale over time. However, some research companies (e.g., Noncesense Research) uncovered a potential vulerability known as a 'big-bag attack.'. Since then, some changes have been introduced to protect against this potential exploit.надежность bitcoin monero cryptonote перспективы bitcoin ava bitcoin кошелек tether эпоха ethereum ethereum blockchain bitcoin 33 flappy bitcoin bitcoin mmm валюта monero количество bitcoin bitcoin fpga wallet tether bitcoin okpay ethereum продам stealer bitcoin ethereum bitcoin bitcoin magazine

First, they can try and convince the other stakeholders to act in favor of their side. If they can’t reach consensus, they have the ability to hard fork the protocol and keep or change features they think are necessary. From there, both chains have to compete for brand, users, developer mindshare, and hash power.WHAT IS ETHEREUM MINING?алгоритмы ethereum bitcoin hacking
