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.
2 pizzas exchanged to 10000 Bitcoins
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?

What miners do is bring them out into the light, a few at a time. Once miners finish mining all these coins, there won’t be more coins rolling out unless the bitcoin protocol changes to allow for a larger supply. Miners get paid in transaction fees for creating blocks of validated transactions and including them in the blockchain.conference bitcoin Hashflare Review: An Estonian cloud miner with SHA-256, Scrypt and Scrypt-N options and currently appears to be the best value.bitcoin brokers claymore ethereum bitcoin fasttech bitcoin курс What is SegWit and How it Works ExplainedA private permissioned blockchain is one where members need to gain permission to enter the system and only a chosen few nodes are allowed to make administrative decisions. Think of a university. Not everyone can enter this university. Aspirants first need to pass an entrance exam. Also, if it is an extremely prestigious university, they will need to have enough money to pay the admission fees. However, the university’s administrative decisions are taken by the student council body, i.e., students elected/selected to take care of these roles. Not every student gets to handle the administrative side.While there have been instances of decentralized platforms being manipulated, these occasions are rare because blockchain platforms have to all agree to any changes. This means that a group of compromised computers would trigger suspicion because a vast number of other computers would have conflicting registers.виталик ethereum lottery bitcoin bitcoin 10000 bitcoin доллар bitcoin cloud monero fork bitcoin exchange bitcoin block half bitcoin исходники bitcoin rpc bitcoin bitcoin machines bitcoin index бесплатные bitcoin double bitcoin bitcoin презентация пополнить bitcoin скрипты bitcoin трейдинг bitcoin bitcoin биржи bitcoin miner cryptocurrency calendar store bitcoin bitcoin презентация

The trick to understanding cryptocurrency is to first understand a bit about normal money — the stuff we have in our pockets.When cryptographic keys are combined with this network, a super useful form of digital interactions emerges. The process begins with A taking their private key, making an announcement of some sort — in the case of bitcoin, that you are sending a sum of the cryptocurrency — and attach it to B’s public key.flappy bitcoin The 'statement' proved by a ring signature is that the signer of a given message is a member of the group. The main distinction with the ordinary digital signature schemes is that the signer needs a single secret key, but a verifier cannot establish the exact identity of the signer.Wondering what is SegWit and how does it work?
