The Story of Bitcoin
No one knows who Satoshi Nakamoto is. It could be a man, a woman or even a group of people. Satoshi Nakamoto only ever spoke on crypto forums and through emails.
In late 2008, Nakamoto published the Bitcoin whitepaper. This was a description of what Bitcoin is and how it works. It became the model for how other cryptocurrencies were designed in the future.
On January 12, 2009, Satoshi Nakamoto made the first Bitcoin transaction. They sent 10 BTC to a coder named Hal Finney. By 2011, Satoshi Nakamoto was gone. What they left behind was the world’s first cryptocurrency.
Bitcoin became more popular amongst users who saw how important it could become. In April 2011, one Bitcoin was worth one US Dollar (USD).
By December 2017, one Bitcoin was worth more than twenty thousand US Dollars! Today, the price of a single Bitcoin is 7,576.24 US Dollars. Which is still a pretty good return, right?
INTERESTING FACT
In 2010, a programmer bought two pizzas for 10,000 BTC in one of the first real-world bitcoin transactions. Today, 10,000 BTC is equal to roughly $38.1 million - a big price to pay for satisfying hunger pangs.

So, Bitcoin has succeeded where other digital cash systems failed. But why? What is cryptocurrency doing differently? The thing that makes cryptocurrency different from fiat currencies and other attempts at digital cash is blockchain technology. Let’s find out how it works…
What is Blockchain?
All cryptocurrencies use distributed ledger technology (DLT) to remove third parties from their systems. DLTs are shared databases where transaction information is recorded. The DLT that most cryptocurrencies use is called blockchain technology. The first blockchain was designed by Satoshi Nakamoto for Bitcoin.
A blockchain is a database of every transaction that has ever happened using a particular cryptocurrency. Groups of information called blocks are added to the database one by one and form a very long list. So, a blockchain is a linear chain of blocks! Once information is added to the blockchain, it can’t be deleted or changed. It stays on the blockchain forever and everyone can see it.
The whole database is stored on a network of thousands of computers called nodes. New information can only be added to the blockchain if more than half of the nodes agree that it is valid and correct. This is called consensus. The idea of consensus is one of the big differences between cryptocurrency and normal banking.
At a normal bank, transaction data is stored inside the bank. Bank staff makes sure that no invalid transactions are made. This is called verification. Let’s use an example;
George owes 10 USD to both Michael and Jackson. Unfortunately, George only has 10 USD in his account. He decides to try to send 10 USD to Michael and 10 USD to Jackson at the same time. The bank’s staff notice that George is trying to send money that he doesn’t have. They stop the transaction from happening.
The bank stopped George from double spending which is a kind of fraud. Banks spend millions of dollars to stop double spending from happening. What is cryptocurrency doing about double spending and how do cryptocurrencies verify transactions? Remember, they don’t have stuff as the bank does!

Cryptocurrency transactions are verified in a process called mining. So, what is cryptocurrency mining and how does it work?
One example is to use this approach to create a decentralized social network that’s resistant to censorship. Most mainstream social apps, such as Twitter, censor some posts, and some critics argue those social apps apply inconsistent standards about what content is censored or 'downranked.'bitcoin today amd bitcoin metal bitcoin bitcoin код bitcoin государство bitcoin транзакция free ethereum key bitcoin транзакции bitcoin bitcoin математика

It used SHA-256, a cryptographic hash function, in its proof-of-work scheme. In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It used scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin used a proof-of-work/proof-of-stake hybrid.ethereum poloniex monero хардфорк

The following year, the finance ministry clarified that, although bitcoin was not 'legal tender,' it could be used as payment and therefore was subject to the same anti-money laundering restrictions as cash and precious metals.лотерея bitcoin You can download (or write yourself if you have the patience) some software called an Ethereum client. Just like BitTorrent or Bitcoin, the Ethereum client will connect over the internet to other people’s computers running similar client software and start downloading the Ethereum blockchain from them to catch up. It will also independently validate that each block conforms to the Ethereum rules.ethereum erc20 foto bitcoin bitcoin кредит 60 bitcoin ethereum shares bitcoin land bitcoin cranes nanopool monero email bitcoin ethereum акции flypool ethereum bitcoin converter вложения bitcoin bitcoin habr captcha bitcoin As Hasu and Su Zhu have eloquently written, Bitcoin can be understood as an independent institution which provides users property rights which are untethered from the state or the legal system.

Or a bit of both?A block consists a header, which includes information identifying the block and linking it to the rest of the chain, and a body of transactions. Miners select these transactions to be included in their block from the pending transaction pool based on their own criteria (most commonly by the highest fees paid).
