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.
Over the years, the concept of a virtual, decentralized currency has gained acceptance among regulators and government bodies. Although it isn’t a formally recognized medium of payment or store of value, cryptocurrency has managed to carve out a niche for itself and continues to coexist with the financial system despite being regularly scrutinized and debated.bitcoin exchanges bitcoin euro bitcoin pdf

This gives an output containing a 256-bit, 64 character length value, which is called the unique ‘hash address.’ Consequently, it is referred to as the hash of the block.bitcoin монеты bitcoin server pplns monero abc bitcoin ethereum windows заработок ethereum monero hardware продам bitcoin

In hexadecimal, 2 digits represent a byte, meaning addresses contain 40 hexadecimal digits, e.g. 0xb794f5ea0ba39494ce839613fffba74279579268. Contract addresses are in the same format, however, they are determined by sender and creation transaction nonce.monero rur bitcoin dice ethereum курс bitcoin index bitcoin code golden bitcoin

flash bitcoin lootool bitcoin количество bitcoin Financing—which in most technology startups would pay salaries—is not needed in a system where people want to work for free. But there is correspondingly no incentive to keep anyone contributing work beyond the scope of their own purposes. Free and open source software software is easy to fork and modify, and disagreements often prompt contributors to copy the code and go off to create their own version. Bitcoin introduces an asset which can accumulate value if work is continually contributed back to the same version of the project, deployed to the same blockchain. So while Bitcoin software itself is not a business for profit—it is freely-distributed under the MIT software license—the growing value of the bitcoin asset creates an incentive for people to resolve fights and continue to work on the version that’s currently running.equihash bitcoin bitcoin cache ethereum акции It’s worth pointing out that it’s generally expected that at some point ordinary desktop users like you or me are expected to stop being full-fledged nodes and bitcoin miners and will instead make use of some specialist service running powerful servers of its own; in a counterfactual universe where Bitcoin was begun in the early 1990s, the changeover would simply have occurred sooner. (And with all the investment money desperately investing in the first Internet bubble, it would be quite easy to start such a service regardless of the technical demands.)
