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 “bc1qm5f3rhukmxyq85ww8zaacydl82tzglkcw4cgd8”
Sent “2 BTC” to
Wallet “bc1qm5f3rhukmxyq85ww8zaacydl82tzglkcw4cgd8”
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.

Bad News Hurts Adoption Rateсложность monero Dominance of either miners or developers may results in changes to the development roadmap which may undermine the system. An example is the erroneous narrative perpetuated by 'large block' miners. The Bitcoin network eventually split into two on August 1, 2017 as some miners pushed for larger blocks, which would have increased the costs for full node operators, who play a crucial role in enforcing rules on a Proof-of-Work blockchain. Higher costs might mean fewer full node operators on the network, which in turn brings miners one step closer to upsetting the balance of power in their own favor.While wallets provide some measure of security, if the private key is intercepted or stolen, there is often very little that the wallet owner can do to regain access to coins within. One potential solution to this security issue is cold storage.ethereum прогнозы bitcoin robot bitcoin монеты

The idea behind Lightning is that every single transaction doesn’t need to be recorded on the blockchain. Instead, only the transaction that creates the channel and the exit transaction are recorded on chain – all others are recorded in the Lightning Network.base bitcoin bitcoin alliance

алгоритм ethereum продажа bitcoin In modernity, zero has become a celebrated tool in our mathematical arsenal. As the binary numerical system now forms the foundation of modern computer programming, zero was essential to the development of digital tools like the personal computer, the internet, and Bitcoin. Amazingly, all modern miracles made possible by digital technologies can be traced back to the invention of a figure for numeric nothingness by an ancient Indian mathematician: Brahmagupta gave the world a real 'something for nothing,' a generosity Satoshi would emulate several centuries later.

But mainstream economists tend to view cryptocurrencies with more than a bit of disdain. And while some traditional financial institutions have warmed to the concept of blockchain technology (or even to the idea of working alongside digital currencies in some form), few have made any suggestion that they will adopt cryptocurrencies wholesale at the expense of fiat money.boxbit bitcoin bitcoin simple bitcoin de bitcoin virus x2 bitcoin депозит bitcoin проекта ethereum bitcoin пирамиды продам ethereum home bitcoin jax bitcoin
