The Importance of Decentralization
As you now know, the blockchain protocol is able to confirm a transaction without a third party and no single authority has control over the network. This is why it is decentralized. But why is this important?
Firstly, decentralization is very secure. In fact, the security features of a decentralized blockchain are so secure that it is almost impossible to hack. Before I explain why I want you to think about how a centralized network functions.
Let’s take a look at an organization like Yahoo. They are one of the largest companies in the world who offer lots of services such as email, news, and video content. All of their data is stored on a centralized server, which in most cases is fine. But what happens if the centralized server fails?
This is exactly what happened in 2016 when a group of hackers managed to gain control of the Yahoo servers, which then allowed them to access more than 3 billion private email accounts.
This isn’t a one-time incident either. Whether its social media, banks, internet service providers or the U.S. election, centralized servers are hacked all the time. However, the good news is that decentralized servers are virtually impossible to hack. Here’s why!
Do you remember how my “What is Blockchain” guide explained that to confirm a transaction, lots and lots of people contribute their computational power? These “Nodes” not only help verify a movement of funds, but they also keep the network secure. This is because more than half of the nodes on the entire network would need to be hacked at the same time for something bad to happen!
Even if this was possible (which it isn’t, really), the hacker would only be able to make changes to the blockchain for 1 block, which in the case of Bitcoin, would be about 10 minutes!
Decentralization isn’t only important for security, but for equality, too. Everyone who engages with the blockchain has the ability to contribute to the system. Furthermore, as each and every transaction is available to view on the public ledger, it makes the network transparent. No corruption, no fraud, and no inequality!
Now that you know why decentralization is important, the next part of my What is Blockchain tutorial is going to look at how anonymous the blockchain is!
How Anonymous is the Blockchain?
When Satoshi Nakamoto created Bitcoin in 2009, he not only wanted to create a fair, secure and transparent payment system, but he also wanted to allow people to send and receive funds anonymously.
Think about how you spend your money in everyday life. When you withdraw money from the ATM machine, the bank knows where you are and how much you are spending. When you use your credit card on holiday, the credit card company also knows where you are and how much you spend.
When you receive your monthly salary, the bank knows how much you are being paid. The list goes on and on, but the point is that third-party intermediaries have lots of information on you. But what gives them the right to know exactly what you’re doing with your hard-earned money? Nothing does! They shouldn’t know.
This is where blockchain technology is different. When you obtain a cryptocurrency, you store it in a digital wallet. This can be stored on your desktop or mobile, online or even on a hardware device. The cryptocurrency is then attached to something called a wallet address. You can have as many wallet addresses as you want, but no two can ever be the same.
When you send funds to somebody, you send them from your wallet to somebody else’s wallet. Here is what a blockchain Bitcoin transaction would look like.
Wallet “1BoatSLRHtKNngkdXEeobR76b53LETtpyT”
Sent “2 BTC” to
Wallet “1CfaunqrVpcXmpLheUVWeSP1KPsKDha1Nb”
On Friday 18th May 2018 at 15.37.
As you can see from the above information, as soon as the transaction is confirmed, everybody can see the amount that was sent and the date and time of the transaction. However, the only information that people know about the sender and receiver is their wallet address.
It is because of this that blockchain transactions are not anonymous, but pseudonymous (like an alias).
However, this is just like spending cash in the physical world. When you walk into your local supermarket and pay with cash, the supermarket knows what you look like, but they don’t have any other information about you!
So, now that you know that the blockchain is pseudonymous rather than anonymous, the next part of my “What is Blockchain” guide is going to look at how it can be used in the real world.

The idea of an overseeing body runs completely counter to its ethos. So if you tell me you have 25 bitcoins, how do I know you’re telling the truth? The solution is that public ledger with records of all transactions, known as the block chain. (We’ll get to why it’s called that shortly.) If all of your bitcoins can be traced back to when they were created, you can’t get away with lying about how many you have.But because mining is a competitive enterprise, miners have come up with ways to gain an edge. One obvious way is by pooling resources.qr bitcoin monero биржи счет bitcoin займ bitcoin
проверить bitcoin bitcoin swiss автосерфинг bitcoin запрет bitcoin Bitcoin is an adaptive and evolving system; it is not static. No one controls the network and there are no leaders capable of forcing changes onto the network. It is decentralized at every layer, and as a result, it has shown to be immune to any type of attack. However, it is not just immune to attack or errors, bitcoin actually becomes stronger as: i) external forces attempt to influence or coopt the network; ii) as individuals within the network make errors; and, iii) as a very function of its volatility, which is often perceived to be a limiting, if not critical, flaw. As bitcoin survives shocks and as individuals learn from errors and adapt to its volatility, bitcoin becomes tangibly more reliable; its demonstration of resilience and immunity causes trust to be reinforced in the network, which increases adoption and makes bitcoin more resistant to future attack or individual errors. It is a positive, self-reinforcing feedback loop. With every failed attempt to coopt or coerce the network, the bitcoin protocol hardens and confidence increases. Every time bitcoin doesn’t die, that very event propels bitcoin forward, and in a fundamentally stronger state than previously existed.bitcoin nachrichten bitcoin crypto bitcoin таблица bitcoin data

The same is true in response to individual accounts at exchanges getting hacked. Not dissimilarly, as threats are identified for those that secure their own bitcoin, more secure wallets are developed and users opt toward more secure ways to safely secure their bitcoin by reducing or eliminating single points of failure. It is a constant evolution borne out of the reality that stressors exist everywhere. The network is not exposed to any critical failures because the entire network iterates through trial and error around the clock, with free competition and endless market opportunity incentivizing innovation. And, with each failure, everyone is on their own and personally accountable. The incentive structure dictates that everyone constantly seeks out better ways of securing bitcoin. Through this process of stress, the network very naturally and organically strengthens.bitcoin валюта яндекс bitcoin bitcoin euro bitcoin wordpress пулы bitcoin
