What is Bitcoin updated

Bitcoin was created by Satoshi Nakamoto, a pseudonym or team that outlined the technology in a 2008 white paper. It’s a charmingly simple concept: Bitcoin is digital money that allows for secure peer-to-peer transactions over the Internet.

  • Unlike services such as Venmo and PayPal, which rely on the traditional financial system and existing debit/credit accounts to allow money to be transferred, bitcoin is decentralized: any two people, anywhere in the world, can exchange money without each other’s participation. Can send without bitcoin. A bank, government, or other institution.
  • Every bitcoin transaction is recorded on a blockchain, which is akin to a bank ledger or a record of customer funds entering and exiting a bank. It is a record of each bitcoin transaction, to put it simply.
  • The bitcoin blockchain is dispersed throughout the network, unlike a bank’s ledger.
  • There will only ever be 21 million bitcoins. It is digital currency that is impervious to growth or manipulation in any way.
  • You don’t have to purchase every single bitcoin; you can only do so if you want to or need to.

  • Bitcoin is the basic currency of the Internet. Unlike government-issued currencies such as the dollar or euro, bitcoin allows online transfers without an intermediary such as a bank or payment processor. Removing those gatekeepers opens up a whole range of new possibilities, including the ability for money to flow more quickly and cheaply around the global Internet, and allows individuals to exert maximum control over their assets.
  • It is legal to use, hold, and trade bitcoin, and it can be spent on everything from travel to charitable donations. It is accepted as a form of payment by businesses including Microsoft and Expedia.
  • Is bitcoin money? It has been used as a medium of exchange, a store of value, and a unit of account – all of which are properties of money. Meanwhile, it exists only digitally; There is no physical version of it.

Who created Bitcoin?

It is helpful to start at the beginning in order to truly comprehend how bitcoin functions. A decade after the invention of the technology, and despite extensive research by journalists and members of the crypto community, it is still unclear who originated bitcoin. creators remain anonymous.

The principles behind bitcoin first appeared in a white paper published online in late 2008 by a person or group named Satoshi Nakamoto.

This paper was not the first idea for digital money drawing from the fields of cryptography and computer science – in fact, the paper referred to earlier concepts – but it was a uniquely elegant solution to the problem of establishing trust between different online entities, Where people may be hiding (like bitcoin’s own creator) under pseudonyms, or may be It is geographically on the other side of the world.

Nakamoto coined a pair of intertwined concepts: the bitcoin private key and the blockchain ledger. When you hold bitcoin, you control it through a private key – a string of random numbers and letters that unlocks the virtual vault containing your purchases. Each private key is tracked on a virtual ledger called a blockchain.

When bitcoin initially arrived, it represented a significant advancement in computer science because it resolved a key issue with online commerce: how do you transmit money between two parties? people without a trusted intermediary (such as a bank) in between? transfer? By solving that problem, the invention of bitcoin has wide-ranging implications: As a currency designed for the Internet, it would allow financial transactions across borders and around the world without the involvement of banks, credit-card companies, lenders, or Is. Even governments. When any two people—no matter where they live—can send payments to each other without meeting those gatekeepers, it creates the potential for an open financial system that’s more efficient, more open, and more innovative. This, in a nutshell, is bitcoin explained.

How Bitcoin works

Unlike credit card networks such as Visa and payment processors such as PayPal, bitcoin is not owned by any individual or company. Bitcoin is the world’s first completely open payment network, in which anyone with an internet connection can participate. Bitcoin was created to be used online and does not rely on financial institutions or other private businesses to complete transactions.

One of the most important elements of bitcoin is the blockchain, which tracks who owns what, in the same way that banks track assets. What sets the bitcoin blockchain apart from a bank ledger is that it is decentralized, meaning anyone can see it and no single entity controls it.

Here are some details about how it works:

The mathematics necessary to validate and record a new transaction are carried out by specialised computers called “mining rigs.” In the early days, a typical desktop PC was powerful enough to participate, allowing anyone eager to try their hand at mining. These days the need for computers is large-scale, specialized, and often owned by businesses or large numbers of individuals pooling their resources. (As of October 2019, mining one bitcoin required 12 trillion times more computing power than when Nakamoto mined the first block in January 2009.)

The collective computing power of miners is used to ensure the accuracy of the ever-growing ledger. Bitcoin is inextricably linked to the blockchain; Each new bitcoin is recorded on it, as is each subsequent transaction with all existing coins.

How does the network incentivize miners to participate in the constant, essential work of maintaining a blockchain—verifying transactions? The bitcoin network has an ongoing lottery in which all mining rigs around the world race to be the first to solve a math problem. Every 10 minutes or so, a winner is found, and the winner updates the bitcoin ledger with new valid transactions. The prizes change over time, but as of early 2020, each winner of this raffle was awarded 12.5 bitcoins.

In the beginning, bitcoin was technically worthless. By the end of 2019, it was trading at around $7,500. As bitcoin’s value has increased, its easy divisibility (the ability to buy a small fraction of a bitcoin) has become a key feature. A bitcoin is currently divisible to eight decimal places (100 millionths of a bitcoin); The bitcoin community refers to the smallest unit as a ‘satoshi’.

Nakamoto set up the network so that the number of bitcoins never exceeded 21 million, thereby ensuring scarcity. There are currently about 3 million bitcoins still available for mining, which will gradually become more and more. The last blocks should be mined in the year 2140.

Cryptocurrencies and traditional currencies share some traits – such as how you can use them to buy things or how you can transfer them electronically – but they also differ in interesting ways. Here are a few highlights.

Key question

How does bitcoin have value?

Essentially the same way a traditional currency does – because it has proven itself to be a viable and convenient way to store value, meaning it can be easily traded for goods, services or other assets. . It is scarce, secure, portable (compared to, say, gold), and easily divisible, allowing transactions of all sizes.

How to get Bitcoin

Purchasing bitcoin using an online exchange like Coinbase is the simplest way to do it. Coinbase makes it easy to buy, sell, send, receive, and store bitcoin without using something called public and private keys.

  • However, if you choose to buy and store bitcoin outside of an online exchange, here’s how it works.
  • Everyone who joins the bitcoin network is issued a public key, which is a long string of letters and numbers, which you can think of like an email address, and a private key, which is the equivalent of a password. Is.
  • When you buy—or send/receive bitcoin—you get a public key, which you can think of as a key that unlocks a virtual vault and gives you access to your money.
  • Anyone can send bitcoin to you via your public key, but only the holder of the private key can access the bitcoin after it has been sent to the “virtual vault”.
  • There are many ways to store bitcoin, both online and off. The most straightforward answer is a virtual wallet.
  • After you sell your bitcoin, the Coinbase app makes it as simple as moving money from one bank to another if you want to move money from your wallet to a bank account. Similar to traditional bank transfers or ATM withdrawals, exchanges like Coinbase set a daily limit, and transactions can take anywhere from a few days to a week to complete.

Key question

What’s the difference between Bitcoin and Blockchain?

The blockchain is a digital ledger that contains records of all bitcoin transactions and public keys. The ledger is effectively a chronological list of transactions. This ledger is copied—exactly—in every computer connected to the bitcoin network, and is constantly checked and secured using vast amounts of computing power around the world. The blockchain concept has become powerful and adaptable, and there are now a wide variety of non-cryptocurrency-related blockchains that are used for things like supply-chain management. The ‘Bitcoin blockchain’ refers specifically to the virtual ledger that records bitcoin transactions and private keys.

How to use Bitcoin

Back in 2013, a bitcoin enthusiast named Laszlo Hanyecz made a message-board post offering 10,000 BTC — which was then worth about $25 — to anyone who would deliver two pizzas to his Jacksonville, Florida, home. As legend has it, those two pizzas, which another bitcoin early-adopter bought from a local Papa John’s, marked the first successful purchase of non-virtual goods using bitcoin. Thankfully, using bitcoin has been much simpler recently!

  • It’s simple: transactions using BTC are no different from those using a credit or debit card, but instead of asking you to enter card information, you simply enter the payment amount and the seller’s public key (email address). same) will be entered. ) through the Wallet App. (When transacting in person using a smartphone or tablet, a QR code will often pop up to simplify the process – when you scan the code, your Wallet app will automatically enter the relevant information.) .)
  • It’s private: One of the benefits of paying with bitcoin is that doing so limits the amount of personal information you provide. You only need to share your name and address if you are purchasing physical goods that need to be shipped.
  • It’s flexible: What you should do with your bitcoin is entirely up to your personal interests. Here are some ideas:
  • You can sell it on an exchange or for cash using a bitcoin ATM.
  • You can spend it online or at brick-and-mortar retailers as you would any other currency using a bitcoin debit card.
  • You can keep some or all of this with you as part of your investment and savings strategy.
  • You can choose the one that is closer to your heart (see).
  • And if you have a serious budget and unfulfilled astronaut dreams? Richard Branson’s Virgin Galactic happily accepts BTC in exchange for the chance to blast off on one of its upcoming space-tourism missions.

What makes Bitcoin a new kind of money?

Bitcoin is global. You can send it all over the world as easily as you can pay with cash in the physical world. It doesn’t close on the weekend, doesn’t charge you a fee for accessing your money, and doesn’t impose any arbitrary limits.

Bitcoin is immutable. Bitcoin is like cash in the sense that a transaction cannot be reversed by the sender. In comparison, credit card, traditional online payment systems, and banking transactions can be reversed after the payment has been made—sometimes months after the initial transaction—due to centralized intermediaries completing the transaction. This creates a higher fraud risk for merchants, which can lead to higher fees for using the credit card.

Bitcoin is private. When paying with bitcoin, there are no bank statements, or any need to provide unnecessary personal information to the merchant. Bitcoin transactions do not contain any identifying information other than the bitcoin address and the amounts involved.

Bitcoin is secure. Due to the cryptographic nature of the bitcoin network, bitcoin payments are fundamentally more secure than standard debit/credit card transactions. When making bitcoin payments, there is no need to send any sensitive information over the internet. The risk of your financial information being compromised, or your identity being stolen, is very low.

Bitcoin is open. Every transaction on the bitcoin network is published publicly, without exception. This means there is no room to falsify transactions (barring the possibility of a 51% attack) or to alter the supply of bitcoins. The software that constitutes the core of bitcoin is free and open-source, so anyone can review the code.

Bitcoin is secure. In more than ten years of existence, the bitcoin network has never been successfully hacked. And because the system is permissionless and open-source, countless computer scientists and cryptographers have been able to investigate the network and all aspects of its security.

Where does Bitcoin come from?

Bitcoin is literally ‘mined’ by a vast, decentralized (also known as ‘peer-to-peer’) network, which are constantly verifying and securing the accuracy of the blockchain. Every single bitcoin transaction is reflected on that ledger, with new information periodically added to a “block” that is added to all the blocks that came before it.
