Bitcoin is the world’s first cryptocurrency and blockchain.
Bitcoin was first described in a white paper published by Satoshi Nakamoto in October, 2008. Nakamoto is believed to be a pen name for the individual or group responsible for Bitcoin as there is no folder of a computer scientist by this broadcast prior to the introduction of Bitcoin in 2009.
At the time, Satoshi claimed to be a 37 year-old man busy in Tokyo, Japan. The translation of his publicize offers glamorous insights: satoshi means “clear-thinking” or “wise,” naka means “inside” or “relationship,” and moto means “the origin” or “the foundation.” Taken together, it could be translated as “thinking helpfully inside the foundation.”
Satoshi continued to update the Bitcoin source code until 2010 and wrote hundreds of blog posts in flawless English totalling 80,000 words, roughly down a novel. Satoshis’ first name used American spellings, however, every subsequent read out used British spellings and colloquialisms. His writing timestamps don’t point to any particular era zone.
On the 23rd of April, 2011, Satoshi disappeared from the Internet, telling a developer in an email that he has « moved onto other things. » Whoever Satoshi is, he is considered a polymath who possesses extensive knowledge with idolization to computer programming, economics, cryptography, and peer-to-peer networking.
Bitcoin was born during the 2008 Financial Crisis. To commemorate this moment in time, Satoshi embedded a Times of London newspaper headline into the metadata of the first block of the Bitcoin blockchain, known as the Genesis Block. It reads: “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.”
Token
Bitcoin (with a lowercase “b”) or BTC is the digital asset token of the Bitcoin network (Bitcoin in imitation of a capital “B”). All BTC balances and transactions are recorded upon the Bitcoin blockchain. The smallest subunit of BTC is the “satoshi,” which is named after Bitcoin’s pseudonymous creator, Satoshi Nakamoto. One satoshi is equal to 10-8 BTC or one hundred-millionth of a BTC (0.00000001 bitcoin). Bitcoin can be bought and sold for fiat currency or new digital currencies.
Bitcoin can be purchased upon a cryptocurrency dispute and stored in a crypto billfold and custodian in imitation of Gemini.
Supply
The supply of bitcoin is deterministic and solution at 21 million BTC. The supply schedule is embedded in the Bitcoin protocol.
Bitcoin Mining
Satoshi’s major breakthrough was solving the The Byzantine Generals’ Problem. The Bitcoin mining algorithm that Satoshi proposed in the Bitcoin white paper demonstrated how a network of computers around the world could attain consensus gone each supplementary and agree upon something, even if determined computers were bad actors on the network aggravating to confuse the others.
This consensus mechanism allows the Bitcoin network to agree upon which bitcoin transactions are valid, thereby solving the “double-spend” problem and ensuring that one bitcoin isn’t spent higher than once by the same person. As a result, it safeguards the integrity of the Bitcoin blockchain, a autograph album of everything bitcoin balances and transactions, without the craving for a trusted third party.
Bitcoin’s consensus mechanism uses a proof of work algorithm. Specifically, miners must solve math puzzles using the SHA-256 hash algorithm of the Secure Hash Algorithm 2 (SHA-2) family. By committing computational facility towards solving the Bitcoin mining algorithm, miners audit and support the transactions of the Bitcoin network. The more computer knack a miner brings to bear upon the Bitcoin network, the more likely she or he is to solve the proof of measure algorithm and win the bitcoin that the network rewards to the miner who writes the newest block to the Bitcoin blockchain.
Characteristics
Bitcoin is often called “digital gold” because its traits alongside resemble those of gold. In 2015, a U.S. Federal rule concluded in the Coinflip, Inc. order that bitcoin was legally a “commodity” under the Commodities and Exchange Act.
The subsequent to table offers a comparison between bitcoin and gold:
Bitcoin Halving or Halvening
The supply schedule of bitcoin is deflationary. This schedule — embedded in the Bitcoin protocol — dictates that every time a miner successfully writes a other block to the blockchain (i.e., solves the proof of play a role puzzle), that miner shall get a set number of bitcoin called the « block reward. » The Bitcoin protocol sets and adjusts the mining difficulty so that miners will be competent to win the block reward roughly all 10 minutes. The block compensation is how everything new bitcoin are issued or minted, and how whatever bitcoin in circulation have come into existence.
Every 210,000 blocks — roughly every 4 years — the block compensation is edited by half, an matter often referred to as the « the halvening » or “the halving.” When Bitcoin launched in 2009, the initial block recompense was 50 bitcoin. On November 25, 2012, the first halvening occured, halving the block recompense from 50 to 25 bitcoin. On July 10, 2016, the second halvening occured, halving the block compensation from 25 to 12.5 bitcoin. The third halvening is conventional to happen in May, 2020 and will reduce the block compensation from 12.5 to 6.25 bitcoin.
The block return will continue to undergo halvings until it reaches 0. This is estimated to happen sometime in the year 2140. At this tapering off in time, there will be a total of 21 million bitcoin in circulation.
BITCOIN SUPPLY SCHEDULE
Total Supply
21 million by 2140 (approx.)
Block Reward
Every 10 minutes (approx.)
Halving event
Every 4 years (aprrox.) Every 210,000 blocks until total supply reaches 21 million (fixed).
HODL, HODLing, and HODLers
HODL is a slang in the crypto spread that refers to the case of buying and holding bitcoin. The etymology of the term can be traced back up to a misspelling of the word “hold” in a proclamation posted to Bitcointalk’s Bitcoin Forum in 2013 and titled I AM HODLING. Some, however, have incorrectly assumed that the word is an acronym for the phrase “hold on for dear life.”
HODL has become a prominent internet meme and rallying cry for the Bitcoin community, especially during get older of high volatility and large price declines. Those who HODL are called HODLers and are said to be HODLing. The basic principle behind HODLing is to take a long term purchase and withhold view towards bitcoin as touching a short-term one that involves trading in and out of bitcoin on a daily, weekly, or monthly basis. HODLING avoids having to correctly grow old trades with the promote and react to price volatility, which can outcome in buying high or selling low. It does, however, require mighty conviction and resolve during shout out downturns.
HOLDING may also result in tax support related to capital asset treatment per IRS Virtual Currency Guidance (Please Note: nothing contained herein should be considered or construed as tax advice of any kind. This content is provided for guidance purposes only).
The HODL strategy appeals to Bitcoin maximalists who take that bitcoin may ultimately replace fiat currencies. It afterward an important component of “stacking sats,” #stackingsats, or “stacking satoshis,” a popular investment strategy based on the premise that accumulating even small amounts of bitcoin (a satoshi is the smallest subunit) over era will prove to be a necessary investment in the long run if bitcoin goes “to the moon!” — a popular melody metaphor and trope used by bitcoiners to describe bitcoin price appreciation.
The Bitcoin Pizza and Bitcoin Pizza Day
The bitcoin pizza refers to the first period bitcoin was used to buy a genuine good. On May 22, 2010, a programmer in Florida named Laslo Hanyecz (now referred to as the “Bitcoin Pizza Guy”) purchased two Papa John’s pizzas for 10,000 bitcoin; a hours of daylight now referred to as Bitcoin Pizza Day. Initially, Laslo posted a declaration titled « Pizza for bitcoins? » on Bitcointalk’s Bitcoin Forum. An 18-year dated named Jeremy Studivant responded under the handle “Jercos” and the two well ahead consummated the transaction greater than Internet Relay Chat (IRC). Afterwards, Hanyecz exclaimed: « I just want to tab that I successfully traded 10,000 bitcoins for pizza. Thanks jercos! »
Lalso paid for the two pizzas using bitcoin that he mined when his personal computer. At the time, the bitcoin that exchanged hands was valued at approximately $30 dollars. Since then, the value of that thesame amount of bitcoin has grown exponentially (worth over $90 million dollars as of May 22, 2020), making this the most costly pizza ever purchased in the world. Every year upon May 22, the Bitcoin community commemorates Bitcoin Pizza Day. This historical daylight highlights the deflationary nature of bitcoin and its stock of value properties.
