Bitcoin is the world’s first decentralized cryptocurrency — a kind of digital asset that records, signs, and sends transactions via the Bitcoin blockchain using public-key cryptography.
The Bitcoin network (with an uppercase “B”) was founded on Jan. 3, 2009, by an anonymous computer programmer (or group of programmers) using the pseudonym “Satoshi Nakamoto.” It is a peer-to-peer electronic payment system that uses a native cryptocurrency called bitcoin (lower case “b”) to transfer value over the internet or act as a store of value similar to gold and silver.
Individual bitcoins are divisible to eight decimal places since each bitcoin is made up of 100,000,000 satoshis (the smallest unit of bitcoin). This enables users to buy fractions of a bitcoin for as little as one dollar.
Bitcoin and other cryptocurrencies are the financial world’s equivalent of email. There is no need for financial middlemen since the money does not exist in physical form. Value is transferred directly between the sender and the recipient. Everything is done in the open using blockchain, a transparent, immutable distributed ledger technology.
The following are the key characteristics of blockchain technology:
- Bitcoin transactions are recorded on a “blockchain,” a public, distributed ledger that anyone can download and contribute to.
- Without any middlemen, transactions are transmitted straight from the sender to the recipient.
- Owners of bitcoins who keep them themselves have full control over them; they can’t be accessed without the owner’s cryptographic key.
- Bitcoin is a digital currency that does not exist in physical form.
- Bitcoin’s supply is limited to 21 million coins. There can be no more bitcoins produced, and there can be no more bitcoin units destroyed.
How Does Bitcoin Work?
Bitcoin users transfer and receive money by entering the public-key information associated with each person’s digital wallet.
A fee is added to each transaction to encourage the dispersed network of individuals validating bitcoin transactions (miners). The fee is given to the miner who adds the transaction to a new block first. Fees operate on a first-price auction mechanism, with the greater the charge, the more likely a miner would process that transaction first
Who Invented Bitcoin?
It’s a bit of a question who should be credited with creating Bitcoin. A white paper published under the pseudonym Satoshi Nakamoto was the first to explain the concept. The writer’s actual identity is still unknown as of this writing. It’s unclear if Satoshi Nakamoto is a single person or a collective.
The white paper, which was released in October 2008, explains how the peer-to-peer digital money would function. Transactions may be processed in batches and then safeguarded using a cryptographic method, according to the author. These batches would be referred to as “blocks,” and they’d be connected in a chain. The word “blockchain” is derived from this.
When Nakamoto mined the first block of Bitcoin in January 2009, the currency was officially established. While Satoshi Nakamoto is credited with creating and launching Bitcoin, others have worked to enhance the code and improve security. The Bitcoin source code is now hosted on GitHub, and many of the major contributors who have been maintaining and upgrading the code are listed there.
How Much Bitcoin Is There?
A technique known as “mining” is used to generate new Bitcoin. The miners deal with transactions as they happen, packaging them into blocks. This contributes to the network’s upkeep, and they are compensated with Bitcoin in exchange for their processing power.
The payout for each block processed was 50 Bitcoin at the time of its debut. Every 210,000 blocks mined, however, the reward is halved. Users also don’t have to worry about the price of Bitcoin being diluted by the influx of new coins on the market. Mining Bitcoin not only takes time and effort, but the program has a limit of 21,000,000 coins. This implies that the total amount of Bitcoins available is limited to 21,000,000.
There are slightly over 18.7 million BTC in circulation at the time of writing.
Where To Buy Bitcoin?
Bitcoin, the most popular cryptocurrency, may be purchased on a variety of exchanges. You can typically purchase Bitcoin using US dollars, but you can also swap it for other global currencies and other cryptocurrencies.
Coinbase, Binance, Kraken, Bitfinex, Huobi, KuCoin, and OKEx are among the most popular exchanges. Various sorts of exchanges may cater to different types of users’ requirements. Users should compare various exchanges before joining up and purchasing Bitcoin.
Every bitcoin transaction must be permanently committed to the Bitcoin blockchain record, which is done via a process known as “mining.” Bitcoin mining is the process of competing for the next block in the chain by utilizing specialized computer equipment known as Application-Specific Integrated Circuit (ASIC) chips.
The procedure for unlocking blockages is as follows:
- Cryptographic hashing is a technology used in crypto mining. This function simply converts any input (messages, words, or other data) into a set length alphanumeric code known as a “hash.”
- Each input generates a totally unique hash, making it almost difficult to anticipate which inputs will result in which hashes. If you change only one character in the input, you’ll get a completely new fixed-length code.
- A number known as a “target hash” is assigned to each new block. Miners must generate a hash that is lower than or equal to the numeric value of the ‘target’ hash in order to earn the privilege to fill the next block. It’s simply a question of trial and error until one miner succeeds, since hashes are totally random.
A Proof-of-Work system is a technique of forcing miners to utilize computers and spend time and energy attempting to accomplish something. It is intended to prevent malicious agents from spamming or disrupting the network.
Whoever unlocks the next block successfully receives a predetermined quantity of bitcoin known as “block rewards” and gets to add a certain number of transactions to the next block. They also profit from any transaction fees associated with the transactions they include in the new block. Every 10 minutes or so, a new block is found.
Block rewards in Bitcoin are decreasing with time. The amount of bitcoins in each block reward is half every 210,000 blocks (approximately four years) to progressively decrease the number of bitcoins entering the space. Miners will earn 6.25 bitcoins for each new block they mine as of 2021. The second bitcoin halving is anticipated in 2024, when block rewards will be reduced to 3.125 bitcoins per block. If demand for bitcoin stays strong, the quantity of new bitcoin entering the market will become more competitive, making purchasing bitcoin more competitive.
Bitcoin’s Energy Consumption
The need that network contributors devote time and resources to create new blocks guarantees the network’s security. However, this safety comes at a cost. The Bitcoin network presently uses approximately 93 Terawatt Hours (TWh) of power per year, almost equivalent to the energy used by the world’s 34th biggest nation.
The effect of Bitcoin on climate change has been widely criticized, ranging from celebrities like Tesla CEO Elon Musk to political organizations like China’s State Council and the United States Senate. While these statistics are worrisome, it’s worth noting that Bitcoin mining only accounts for 1.29 percent of total energy usage in any given nation. Not to mention, Bitcoin is a complete financial system with energy consumption that can be measured and tracked, as opposed to the fiat system, which cannot be accurately measured and relies on a variety of additional layers to function, such as ATMs, card machines, bank branches, security vehicles, storage facilities, and massive data centers.
A number of efforts, such as the Crypto Climate Accord and the Bitcoin Mining Council, are attempting to reduce Bitcoin’s carbon footprint by pushing miners to utilize renewable energy sources.
