What is Bitcoin ? How does it work in the Blockchain ?

   Whether you've been holding since the early days of Bitcoin or recently heard your weird uncle tell you to invest in cryptocurrency, you might be wondering exactly how Bitcoin works. While this newish type of virtual currency has made headline after headline over the last decade, its underlying concepts and function are simpler than you might think.


 Let's take a look at the basics. Bitcoin at its core is a software protocol based on the blockchain. The digital token has a value based on what others are willing to pay for it, or simply based on the concept of supply and demand. When it first came out, a Bitcoin was worth about 0.0008 cents, but as more people bought into the idea and bought the coin, the price has now climbed to over 50,000 U.S. dollars. Bitcoin is a digital currency based on a decentralized system that records each transaction on a Ledger, also known as a blockchain. That may sound confusing, but it essentially means that the Bitcoin network isn't run from some guy's basement on the other side of the world. Rather, it's ran on thousands of computers across the world simultaneously, without one centralized controller, while many people just buy Bitcoin through Coinbase or other apps, the digital tokens themselves are actually created by Bitcoin miners, which use high-powered computer rigs to solve complex math problems. They confirm transactions on the decentralized blockchain to keep the buying and selling moving smoothly. After a block of transactions is confirmed by miners, the miners themselves are rewarded with a small number of bitcoins. Bitcoin mining is ultimately the underpinnings of how Bitcoin works.


 Miners lend their computing power to the blockchain and get rewarded with digital currency. On January 3rd, 2009, Satoshi Nakamoto mined the first block, the Genesis Block, and was rewarded 50 bitcoins. This brought Bitcoins into existence. But let's learn a little bit more about blockchain. Blockchain isn't Bitcoin as much as Bitcoin isn't the blockchain. Blockchain itself is actually a software protocol that can be used in many less exciting applications to the normal listener like manufacturing, software compliance, banking and other software applications, the first blockchain was described by Satoshi Nakamoto 2008, the creator of Bitcoin. Initially, the two terms were always used together, but blockchain diverged into an even bigger software and technology phenomenon. Blockchains are simple in theory, it's a digital chains of blocks, each block being a group of information. Think of it like folders. In a sense, the blocks are arranged in order chronologically, and they cannot be unordered. It's like a timeline of digital events that are independently verified and securely held through a decentralized network, meaning thousands of computers across the world. You could agree to pay a friend $20 through a blockchain and that agreement would forever be on the blockchain, ensuring you pay when the time comes. It's this secure software protocol that stands as the basis of Bitcoin by having a secure transaction network in the blockchain, Bitcoin tokens are transferred from person to person, securely tracked through blocks of information, all decentralized and anonymous, run by mining computers across the world. Because blockchains are distributed ledgers, the entire Bitcoin blockchain is public. By making such a complex amount of information public, it can be ensured that no changes are made over time because other people would see the changes being made or see that their blockchain that they can see different than the one other person is providing no central authority overseas Bitcoin transactions. Rather, the miners work together to validate them. Bitcoin users will generally have wallet addresses and that's like a string of letters and numbers that can be identified in the blockchain and serve as a sending or receiving location. For digital currency. This address serves as a unique identifier on the blockchain anytime Bitcoin is sent or received to or from this address it's logged in the chain, and it can be traced back and forth and back and forth. 



But what makes Bitcoin worth anything at all? Well, nothing other than what people are willing to pay for it. Well, that and that. There can never be more than 21 million Bitcoin in existence. This creates a finite supply. The only way new Bitcoin is made is through mining, or as a reward to miners for validating transactions. The amount of Bitcoin a miner gets for processing a block slowly decreases over time in a process known as having. The reward for mining is cut in half for every 210,000 blocks mined. This process is set to continue until 2140 when all of the bitcoins, all 21 million of them, are mined. After this, miners will get paid fees based on a structure to continue processing transactions on the blockchains. This also means that mining can get less profitable over time as the rewards decrease. However, that's only if the price stays the same. If the price per Bitcoin goes up. If it goes up faster than the rewards decrease, mining can actually get more profitable, which sometimes happens. The limited supply of Bitcoin also means that there's a supply and demand issue. As we mentioned, if more people wanted to buy bitcoins due to a limited supply, the price would need to go up. That's why we've seen a such meteoric rise in bitcoins price. If the lowest owner of Bitcoin doesn't want to sell for anything less than $50,000, then Bitcoin would be valued at $50,000, because that's the lowest you could buy it for. That's a little bit oversimplified for supply and demand, but essentially Bitcoin is worth what people are willing to pay for it. It doesn't have any intrinsic value. All of this serves as a very basic overview of bitcoins and blockchains, though. We haven't really gone into hashed data, different risks to the Bitcoin network, like something called a   51% attack, or even the cryptography and security that goes into making the blockchain and blockchain wallets completely secure. However to the casual or beginning Bitcoin owner or buyer. That info can sometimes overwhelm and confuse, and warrants its own individual research. In summary, Bitcoin is a digital token validated by a secure, decentralized software network that runs off of computers all around the world. Known as miners, these miners ensure people can buy and sell bitcoins securely, and for their trouble, the miners get rewarded with a small amount of new Bitcoin.


 You can only ever be 21 million Bitcoin in existence and due to that limited supply, as more people want to buy Bitcoin, the price goes up and up until more people are willing to sell it at a given price, supply and demand. No one really knows what's going to happen to Bitcoin or its price, but one thing is for sure, fortunes have been made and lost on the cryptocurrency, but it's likely here to stay. But of course when you make a fortune. The IRS wants a piece of it. If you've bought Bitcoin or any cryptocurrency, you're going to need to file income tax on your earnings or risk being audited by the IRS. In the US, one of the simplest ways to do that is by using legible. Their tax software solution allows you to quickly create tax documents for your cryptocurrency activity for the tax year and analyze your gains and portfolio value throughout the year and be able to maximize your tax savings at the year by making smart informed moves you can learn about the coherent secure system and use it to file your taxes.

Why the US government 30$ trillion owe?

  The United States is in a lot of debt. Currently the country owes $27.2 trillion. But who would even lend them that much money? Who does the US owe this massive sum?  Well, the answer to that is pretty simple. In large part, it owes itself that money, but there's also quite a few other countries it owes to. the US essentially owes two groups of people, the general public, which can be other countries or even investors in the US and itself. But before we get into who makes up those groups and what the percentages look like, first let's get some basics. Whenever the US government needs money, it raises that money through the issuing of savings bonds or treasury bonds. These bonds are basically pieces of paper that say the US will pay the person or agency that buys it back with a little bit of interest. Many people want to buy bonds because they're pretty solid investments, like banks, foreign governments, and maybe even you. The debt ceiling, which you may have heard about,...

China really does not want war? Taiwan then whose? Why is Taiwan so important to America and China?

China is playing with peril. still, America will intermediate militarily to cover the island, If China invades Taiwan. This is what US President Joe Biden said during a meeting with the leaders of the Quintet in Tokyo on May 23. China is not sitting still. Beijing's Foreign Ministry prophet Wang Wenbin stressed that Taiwan is an integral part of mainland China. There is no room for concession or concession. Encouraging Taiwan's independence would be like playing with fire. This is what Chinese President Xi Jinping said in 2021. still, there would be nothing to worry about, If the issue was limited to such a war of words. The constitution also has a law on Taiwan called the Anti-Association Law, which states that if Taiwan does not unite with China, also China is naturally obliged to intermediate militarily in Taiwan. multitudinous international relations judges believe that if there is a war between China and the United States in the future, Taiwan will be the flash point of th...

The End of Doller empire !

The End of Doller empire!  Saudi Arabia is in discussions with China to price some of its oil sales in yuan, but as ties with Washington continue to be strained. Beijing and Moscow are diversifying. China and Russia have taken another step closer towards dumping the dollar and agreed to trade in their respective national currencies, the Russian ruble and the Chinese yuan. The End of Doller empire Hi everybody. the US dollar has been the most powerful currency in the world for 80 long years.  This reserve currency status gives the United States such unprecedented power over the world economy that can cripple the economy of any country within a fortnight. And because of this power, it has even dominated giant players like Russia and China. But you know what guys? This is where China and Russia have actually come up with a master plan to kill the dollar dominance in the world. And if you look at the past 10 years data, you will see that it's actually working out quite well. In 19...

Are we alone in the universe?

A dog! They are looking at the stars in the sky. As we see. May or may not be breathing. Creating or not creating. But one question is right between them. Just like us. Are we alone in the universe? When the Armstrongs returned from the moon, they were quarantined for several days. Why? Because if a virus or any other germs came through them from the moon, i.e. very close to our satellite, scientists thought about the possibility of life in this satellite, isn't it strange? Let's go to the universe in search of life. Earth is the only source of life? This question is very old. There are ten thousand times more stars in our Milky Way alone than there are sand dunes on this planet. To be more precise, this number is ten to the power twenty-two to ten to the power twenty-four or more. If five percent of its stars are like our sun, then the number stands at five hundred billion billion stars. Very good talk. If we assume that even one out of every five Sun-like stars has water and ...

What is the meaning of the rate race?

It's complicate to calculate exactly when you joined the rat race. But rest assured you're in this race. Flash back the time of reading in class eight? Ahead of the education test computation Algebra figures doctoring all the complex formulas of wisdom Get up beforehand in the morning at the private instructor's house and study late at night. You must have spent a lot of time busy with work compared to your age? We all spent. At that time, the guardian must have said that this is a many further days. Life is peaceful and peaceful only when the education test is over. You have heard these words numerous times in numerous occurrences of life. Take the SSC test, you get freedom when you get to council. Life will be full of joy once you can get into varsity. Enter the job life formerly. Having fun with your own plutocrat is different. Have you heard of this?  Can you match the numbers standing at the end of the age clock? What do you think? Has life gotten a little easier after...

What is Obsessive Compulsive Disorder?

Depression has an additional air or disease in English which is called Obsessive Compulsive Disorder or OCD and in Bengali it is called Suchibai. Sounds like a very common disease doesn't it? We do not give importance to this disease because it is made fun of because it is considered normal. And on that occasion, this weed grows bigger. Pain increases and that pain is much more intense than depression. Obsessive compulsive disorder (OCD) is a common mental health condition where a person has obsessive thoughts and compulsive behaviors. OCD can affect men, women and children. Some people start having symptoms early, often around puberty, but it usually starts during early adulthood. Here is a detail view of OCD. According to the report of the World Health Organization, about 700,000 people commit suicide in the world every year. Ninety percent of these suicides are due to depression. People with Obsessive Compulsive Disorder or OCD may rarely reach the stage of suicide. But the life...

What is a meme stock? How does work a meme stock ?

With the growing interest in the stock market by new investors, the frenzy has created a new type of stock, the meme stock. What Is A Meme Stock? Meme stocks don't mean the internet's favourite meme from the weak is now trading on the stock market. Rather, stocks for companies themselves have gone viral online, causing investors to purchase them just for the meme. Meme stocks are getting more and more popular, and if you're an early adopter, you can stand to make some crazy returns, like with GameStop or AMC. But let's take a closer look to figure out what exactly a meme stock Meme stocks are a fairly new term, and they spawned out of trading hype and hysteria from 2020 and 2021, with discussions of the stock originating on Reddit or other online forums. Meme stocks garnered and do garner so much attention simply because of how fast they rise for seemingly no reason. Typically a good stock would rise 30 to 50% in a year, but a meme stock could make that move overnight. ...

Who controls of our whole economic money?

  I'm gonna start this article with a quote. Henry Ford once said it is well enough that the people of the nation do not understand our banking and monetary system. For if they did, I believe there would be a revolution before tomorrow morning. I quote this because it encapsulates the fact that the contents of this article may be unsettling compared to the articles that I normally make.  I still feel compelled to make this article because I've been exploring the financial world for the last four years and it's definitely given me a more complete view of the world I want to share some of what I've come across with you guys. I'm also going to do a article about cryptocurrencies like Bitcoin in the future and to understand why Bitcoin and other cryptocurrencies may continue to rise. It's critical that you understand the contents of this article. I hope that you find this topic interesting and that inspires you to do your own research afterwards.  Now, with that sai...

Why money worth anything ?

  Money is arguably one of the most important things in the world. While happiness and joy might outrank it at least on your uplifting Instagram feed, money does seem to make things easier. When you actually stop and think about paper money, though, we're left with a perplexing conundrum. There's nothing inherently valuable about these banknotes, at least today. So why does money have any value at all? Over time? How paper money is valued has actually changed, so to understand how modern money is worth anything. First, we have to look back to the early days of paper money. In the early days of governmental currency, money wasn't paper. Rather, it was usually a coin made of a precious metal like gold or silver. The value of that money was intrinsic as the value of the metal that made it up. If you melted a gold coin down, you'd have the same amount of gold as the coin was worth. As this system of money became impractical, governments decided to come up with a new way of ...

What is post traumatic disorder?

Catherine is a working girl in a city. The house is quite far from the workplace. He has to travel by public transport. One day it was quite late to leave the office due to work pressure. He boarded a bus to go home. And just before the last stop at his house. Quite a lot of the way. So he put it on the seat. The eyes may have come from fatigue. When he opened his eyes he saw that he was the only passenger in the bus and a boy was standing next to the driver. He asked the driver if the bus will not go forward? The driver said he would go.
