How does Bitcoin work?

Bitcoins work

If you cut the information inside computers into smaller pieces, you will find 1s and 0s. These are called bits. You already know about coins. Bitcoins are just the plural of Bitcoin. They are coins stored in computers. They are not physical and only exist in the digital world! By the end of the guide, even total beginners will understand what Bitcoin is, how to get Bitcoin, and how to use Bitcoin. There are three types of people in this world: the producer, the consumer, and the middleman. This is the same in almost every industry! Bitcoin was invented to remove one type of middleman — the banks. They take a fee for processing. Once the money reaches the bank in the U. Banks store lots of private data about their customers. Many banks have been hacked over the last 10 years, which is very dangerous for the people that use banks. This is why it is important to understand how does Bitcoin work. They have too much control over the people that use the banks and they have abused their power. They played a big role in the financial crisis of , too. Bitcoin started in , just after that crisis. Many people believe that the crisis was one of the reasons for creating Bitcoin. Who created Bitcoin? The creator of Bitcoin is unknown. The name used was Satoshi Nakamoto, but this was a fake name and nobody knows who the real creator is. The solution was to build a system that has no single authority like a bank. The banks and the governments controlled the currencies, so a new currency had to be created. Bitcoin is the solution: it has no single authority. That means no banks, no PayPal, no government to be able to tell the bank to freeze your account. The creator of Bitcoin made three main concepts for Bitcoin that are essential in understanding the principles of Bitcoin:. Then, both computers start talking to each other and your browser shows images, buttons, etc. In a decentralized network, the data is everywhere. If Google used a decentralized network, you would still be able to see the data, because it is everywhere and not just in one place. This means that Google would never go offline! In World War II cryptography was used a lot. It converted radio messages into code that nobody could read. To read it, you would need to convert back to the original message. To do that, you needed a key. It was possible through mathematical formulas! Bitcoin uses cryptography in the same way. Instead of converting radio messages, Bitcoin uses cryptography to convert transaction data. That is why Bitcoin is called a crypto currency. Knowing that takes you one step closer to understanding how does Bitcoin work. Bitcoin does this using the blockchain. Last week when John visited the bakery, only one cake was left. Four other people wanted it too. This is the main concept of supply and demand: when something is limited, it has more value. The more people that want it, the more the price of it will go up. Bitcoin uses this same concept. The supply of bitcoin is limited. Bitcoin is produced at a fixed rate, which will decrease over time — it halves every four years. Bitcoin has a limit of 21 million coins; once there are 21 million Bitcoins, no more Bitcoins can be created. How many Bitcoins are there at the moment? Well, currently To really learn how Bitcoin works, we should move on to how the Bitcoin transactions work…. Now, let us see how these concepts work together. To record transactions, we need to put them in a database like an Excel sheet. This would normally be stored in one place in a centralized network. But because Bitcoin uses a decentralized network, the Bitcoin database is shared. This shared database is known as a distributed ledger and it is accessed using the blockchain. To learn more about blockchain technology and understand what are Bitcoins from the blockchain perspective better, read my Blockchain Explained guide. The message would be then broadcasted to all the computers in the network. When you create a Bitcoin wallet to store your Bitcoin , you receive a public key and a private key. Public keys and private keys are a set of long numbers and letters; they are like your username and password. Both are very important for truly understanding how does Bitcoin work. People need your public key if they want to send money to you. Because it is just a set of numbers and digits, nobody needs to know your name or email address, etc. As for your private key , you should never let anyone see it. On the blockchain, your private key is your identity. You use your private key to access your Bitcoin. If someone sees it, they can steal all your Bitcoin — so be very careful! So yes, technically, your identity can be faked. If someone gets your private key, they can use it to send Bitcoin from your wallet to their wallet. This is why you must keep your private key very, very safe. Your real identity your name, address, etc. Bitcoin transactions are grouped together and stored in blocks. These blocks are linked back to one another in a series. This is why it is called a blockchain. Each transaction in the block has a public key written on it. If it is your Bitcoin, it will be your private key that is written on it. Because each block is connected to the block before it, no Bitcoin can be spent twice. If someone tried to send the same Bitcoin twice, this is what would happen:. This is one of the key elements of how does Bitcoin work. This is possible, but it is near impossible to achieve. To add new blocks to the blockchain, they must be mined. This process is called mining because the nodes that do it are rewarded with Bitcoin — like gold miners being rewarded with gold. In mining, the nodes must process Bitcoin transactions and verify that they are real. To do this, they must solve a mathematical problem. When the problem is solved, the block of transactions is verified, and a new block is created. Each block has a new problem and a new solution for miners to find. The first node to solve this problem gets new Bitcoins. Mining uses a lot of electricity, so the miners need to be rewarded! You should already know what most of the advantages of Bitcoin are after reading this far into the guide. Then you will fully know and be an expert on how does Bitcoin work question. Another key element of how does Bitcoin work is that anyone anywhere in the world can send money to each other. With a bank, you must use your ID when you apply for an account. Because of this, hundreds of millions of people around the world do not have bank accounts. They cannot send or receive money. But now, with Bitcoin, they finally can! If you send it using Bitcoin, it will only take around 10 minutes. The fee for Bitcoin changes often and the developers are trying to keep it as low as possible. At present It is cheap because there is no middleman banks, PayPal, etc. This what Bitcoin is all about. There are many advantages to Bitcoin, but there are some disadvantages too on how does Bitcoin work. Bitcoin started in , remember? Since then, a lot of newer cryptocurrencies have been made that are a lot faster than Bitcoin. The fees got high because the popularity of Bitcoin was too much for the Bitcoin network to deal with — there were too many people using it. This is something the Bitcoin developers are trying to improve, and so far, it seems to be working. The downside of how does Bitcoin work is that it needs private keys, public keys, opening and using a wallet, etc. When you want to send a payment to someone, you must type a long set of numbers and letters their public key into your computer. This is like when internet browsers first started — you had to type a long number into the address bar. Later, the www. Bitcoin needs to become easy to use so that everyone in the world can use it, just like browsing the internet is. As I said earlier, electricity costs for mining are high. The miners are rewarded with Bitcoin, so they are still making a profit. However, the electricity used by miners is very bad for the environment now you know some downsides of the question about how does Bitcoin work. Other cryptocurrencies, such as NEO and Lisk, are using a different mining system that uses much less electricity. This system is called PoS Proof of Stake. That system is called PoW Proof of Work. All the miners work on the same block at the same time, trying to win the race. This means that all miners are using electricity on every block that is created. In PoS, only one miner can mine the block. When the next block is created, another miner is chosen to mine it. This way, it is only one miner using electricity on each block. You might have heard of something called Silk Road. This was a market on the dark web — an anonymous part of the internet that must be opened using a special browser. On Silk Road, you could buy lots of illegal things, and Bitcoin the currency that is used. Silk Road started in but was shut down in by the FBI. This was very bad for Bitcoin, and some governments have tried to ban Bitcoin for this reason. It is the biggest example of how Bitcoin can be abused, although, crime can happen with all currencies. The only thing left is to know how to buy it. So, how do you buy Bitcoin? This is the simplest way, but you normally must use your identity. Using a broker exchange is a bit like when you go to a travel agent to convert your local currency into a foreign currency like USD for JPY, for example. However, with Coinbase and Coinmama, etc. There is no broker, so they pay no fees! Amy will always have to pay John the Bitcoin because P2P exchanges use an escrow service. When John asks Amy for the Bitcoin, the Bitcoin is sent into the escrow. When John pays Amy his money, the escrow sends John his money. John and Amy have no control over the escrow, so it is always fair. And fair trade is one of the essentials on understanding how does Bitcoin work. So, it is possible to use P2P exchanges to buy Bitcoin anonymously. You can even pay in cash paper money! You can also pay with bank transfer! This is the least common way to buy Bitcoin. There are not many Bitcoin ATMs in the world, so you will have to use this map to see if there is one near you. In that guide, I give you full instructions on setting up your wallet, verifying your identity and buying Bitcoin with each payment method. The invention of Bitcoin is only the beginning. What are your thoughts? Do you think that Bitcoin will replace banks? Or does it need to improve first? By answering the above questions, you can test what you have learned in this guide.

As a new user, you can get started with Bitcoin without understanding the technical details. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should be used only once. The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. The integrity and the chronological order of the block chain are enforced with cryptography. A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast to the network and usually begin to be confirmed within minutes, through a process called mining. Mining is a distributed consensus system that is used to confirm pending transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all the subsequent blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively to the block chain. In this way, no group or individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends. This is just a short summary of Bitcoin. If you want to learn more of the details, you can read the original paper that describes its design, the developer documentation , or explore the Bitcoin wiki. How does Bitcoin work?
