History of bitcoin
Bitcoin is a cryptocurrency, a digital asset designed to work as a medium of exchange that uses cryptography to control its creation and management, rather than relying on central authorities. It was invented and implemented by the presumed pseudonymous Satoshi Nakamoto, who integrated many existing ideas from the cypherpunk community. Over the course of bitcoin's history, it has undergone rapid growth to become a significant currency both on- and offline. From the mid 2010s, some businesses began accepting bitcoin in addition to traditional currencies.
Pre-history
Prior to the release of bitcoin there were a number of digital cash technologies starting with the issuer based ecash protocols of David Chaum and Stefan Brands. The idea that solutions to computational puzzles could have some value was first proposed by cryptographers Cynthia Dwork and Moni Naor in 1992. The idea was independently rediscovered by Adam Back who developed hashcash, a proof-of-work scheme for spam control in 1997. The first proposals for distributed digital scarcity based cryptocurrencies were Wei Dai's b-money and Nick Szabo's bit gold. Hal Finney developed reusable proof of work (RPOW) using hashcash as its proof of work algorithm.
In the bit gold proposal which proposed a collectible market-based mechanism for inflation control, Nick Szabo also investigated some additional aspects including a Byzantine fault-tolerant agreement protocol based on quorum addresses to store and transfer the chained proof-of-work solutions, which was vulnerable to Sybil attacks, though.
Creation
On 18 August 2008, the domain name bitcoin.org was registered. Later that year, on 31 October, a link to a paper authored by Satoshi Nakamoto titled Bitcoin: A Peer-to-Peer Electronic Cash System was posted to a cryptography mailing list. This paper detailed methods of using a peer-to-peer network to generate what was described as "a system for electronic transactions without relying on trust". On 3 January 2009, the bitcoin network came into existence with Satoshi Nakamoto mining the genesis block of bitcoin (block number 0), which had a reward of 50 bitcoins. Embedded in the coinbase of this block was the text:
The Times Jan/03/2009 Chancellor on brink of second bailout for banks.
The text refers to a headline in The Times published on 3 January 2009. This note has been interpreted as both a timestamp of the genesis date and a derisive comment on the instability caused by fractional-reserve banking.:18
The first open source bitcoin client was released on 9 January 2009, hosted at SourceForge.
One of the first supporters, adopters, contributors to bitcoin and receiver of the first bitcoin transaction was programmer Hal Finney. Finney downloaded the bitcoin software the day it was released, and received 10 bitcoins from Nakamoto in the world's first bitcoin transaction on 12 January 2009 (bloc 170). Other early supporters were Wei Dai, creator of bitcoin predecessor b-money, and Nick Szabo, creator of bitcoin predecessor bit gold.
In the early days, Nakamoto is estimated to have mined 1 million bitcoins. Before disappearing from any involvement in bitcoin, Nakamoto in a sense handed over the reins to developer Gavin Andresen, who then became the bitcoin lead developer at the Bitcoin Foundation, the 'anarchic' bitcoin community's closest thing to an official public face.
The value of the first bitcoin transactions were negotiated by individuals on the bitcoin forum with one notable transaction of 10,000 BTC used to indirectly purchase two pizzas delivered by Papa John's.
On 6 August 2010, a major vulnerability in the bitcoin protocol was spotted. Transactions weren't properly verified before they were included in the transaction log or blockchain, which let users bypass bitcoin's economic restrictions and create an indefinite number of bitcoins. On 15 August, the vulnerability was exploited; over 184 billion bitcoins were generated in a transaction, and sent to two addresses on the network. Within hours, the transaction was spotted and erased from the transaction log after the bug was fixed and the network forked to an updated version of the bitcoin protocol. This was the only major security flaw found and exploited in bitcoin's history.
Satoshi Nakamoto
Main article: Satoshi Nakamoto
"Satoshi Nakamoto" is presumed to be a pseudonym for the person or people who designed the original bitcoin protocol in 2008 and launched the network in 2009. Nakamoto was responsible for creating the majority of the official bitcoin software and was active in making modifications and posting technical information on the bitcoin forum. There has been much speculation as to the identity of Satoshi Nakamoto with suspects including Dai, Szabo, and Finney – and accompanying denials. The possibility that Satoshi Nakamoto was a computer collective in the European financial sector has also been discussed.
Investigations into the real identity of Satoshi Nakamoto were attempted by The New Yorker and Fast Company. The New Yorker's investigation brought up at least two possible candidates: Michael Clear and Vili Lehdonvirta. Fast Company's investigation brought up circumstantial evidence linking an encryption patent application filed by Neal King, Vladimir Oksman and Charles Bry on 15 August 2008, and the bitcoin.org domain name which was registered 72 hours later. The patent application (#20100042841) contained networking and encryption technologies similar to bitcoin's, and textual analysis revealed that the phrase "... computationally impractical to reverse" appeared in both the patent application and bitcoin's whitepaper. All three inventors explicitly denied being Satoshi Nakamoto.
In May 2013, Ted Nelson speculated that Japanese mathematician Shinichi Mochizuki is Satoshi Nakamoto. Later in 2013 the Israeli researchers Dorit Ron and Adi Shamir pointed to Silk Road-linked Ross William Ulbricht as the possible person behind the cover. The two researchers based their suspicion on an analysis of the network of bitcoin transactions. These allegations were contested and Ron and Shamir later retracted their claim.
Nakamoto's involvement with bitcoin does not appear to extend past mid-2010. In April 2011, Nakamoto communicated with a bitcoin contributor, saying that he had "moved on to other things".
Stefan Thomas, a Swiss coder and active community member, graphed the time stamps for each of Nakamoto's 500-plus bitcoin forum posts; the resulting chart showed a steep decline to almost no posts between the hours of 5 a.m. and 11 a.m. Greenwich Mean Time. Because this pattern held true even on Saturdays and Sundays, it suggested that Nakamoto was asleep at this time, and the hours of 5 a.m. to 11 a.m. GMT are midnight to 6 a.m. Eastern Standard Time (North American Eastern Standard Time). Other clues suggested that Nakamoto was British: A newspaper headline he had encoded in the genesis block came from the UK-published newspaper The Times, and both his forum posts and his comments in the bitcoin source code used British English spellings, such as "optimise" and "colour".
An Internet search by an anonymous blogger of texts similar in writing to the bitcoin whitepaper suggests Nick Szabo's "bit gold" articles as having a similar author. Nick denied being Satoshi, and stated his official opinion on Satoshi and bitcoin in a May 2011 article.
In a March 2014 article in Newsweek, journalist Leah McGrath Goodman doxed Dorian S. Nakamoto of Temple City, California, saying that Satoshi Nakamoto is the man's birth name. Her methods and conclusion drew widespread criticism.
In June 2016, the London Review of Books published a piece by Andrew O'Hagan about Nakamoto. The real identity of Satoshi Nakamoto still remains a matter of dispute.
Growth
2011
Based on bitcoin's open-source code, other cryptocurrencies started to emerge.
The Electronic Frontier Foundation, a non-profit group, started accepting bitcoins in January 2011, then stopped accepting them in June 2011, citing concerns about a lack of legal precedent about new currency systems. The EFF's decision was reversed on 17 May 2013 when they resumed accepting bitcoin.
In June 2011, WikiLeaks and other organizations began to accept bitcoins for donations.
2012
In January 2012, bitcoin was featured as the main subject within a fictionalized trial on the CBS legal drama The Good Wife in the third-season episode "Bitcoin for Dummies". The host of CNBC's Mad Money, Jim Cramer, played himself in a courtroom scene where he testifies that he doesn't consider bitcoin a true currency, saying, "There's no central bank to regulate it; it's digital and functions completely peer to peer".
In September 2012, the Bitcoin Foundation was launched to "accelerate the global growth of bitcoin through standardization, protection, and promotion of the open source protocol". The founders were Gavin Andresen, Jon Matonis, Patrick Murck, Charlie Shrem, and Peter Vessenes.
In October 2012, BitPay reported having over 1,000 merchants accepting bitcoin under its payment processing service. In November 2012, WordPress started accepting bitcoins.
2013
In February 2013, the bitcoin-based payment processor Coinbase reported selling US$1 million worth of bitcoins in a single month at over $22 per bitcoin. The Internet Archive announced that it was ready to accept donations as bitcoins and that it intends to give employees the option to receive portions of their salaries in bitcoin currency.
In March, the bitcoin transaction log, called the blockchain, temporarily split into two independent chains with differing rules on how transactions were accepted. For six hours two bitcoin networks operated at the same time, each with its own version of the transaction history. The core developers called for a temporary halt to transactions, sparking a sharp sell-off. Normal operation was restored when the majority of the network downgraded to version 0.7 of the bitcoin software. The Mt. Gox exchange briefly halted bitcoin deposits and the exchange rate briefly dipped by 23% to $37 as the event occurred before recovering to previous level of approximately $48 in the following hours. In the US, the Financial Crimes Enforcement Network (FinCEN) established regulatory guidelines for "decentralized virtual currencies" such as bitcoin, classifying American bitcoin miners who sell their generated bitcoins as Money Service Businesses (or MSBs), that may be subject to registration and other legal obligations.
In April, payment processors BitInstant and Mt. Gox experienced processing delays due to insufficient capacity resulting in the bitcoin exchange rate dropping from $266 to $76 before returning to $160 within six hours. Bitcoin gained greater recognition when services such as OkCupid and Foodler began accepting it for payment.
On 15 May 2013, the US authorities seized accounts associated with Mt. Gox after discovering that it had not registered as a money transmitter with FinCEN in the US.
On 17 May 2013, it was reported that BitInstant processed approximately 30 percent of the money going into and out of bitcoin, and in April alone facilitated 30,000 transactions,
On 23 June 2013, it was reported that the US Drug Enforcement Administration listed 11.02 bitcoins as a seized asset in a United States Department of Justice seizure notice pursuant to 21 U.S.C. § 881. This marked the first time a government agency claimed to have seized bitcoin.
In July 2013, a project began in Kenya linking bitcoin with M-Pesa, a popular mobile payments system, in an experiment designed to spur innovative payments in Africa. During the same month the Foreign Exchange Administration and Policy Department in Thailand stated that bitcoin lacks any legal framework and would therefore be illegal, which effectively banned trading on bitcoin exchanges in the country.
On 6 August 2013, Federal Judge Amos Mazzant of the Eastern District of Texas of the Fifth Circuit ruled that bitcoins are "a currency or a form of money" (specifically securities as defined by Federal Securities Laws), and as such were subject to the court's jurisdiction, and Germany's Finance Ministry subsumed bitcoins under the term "unit of account" – a financial instrument – though not as e-money or a functional currency, a classification nonetheless having legal and tax implications.
In October 2013, the FBI seized roughly 26,000 BTC from website Silk Road during the arrest of alleged owner Ross William Ulbricht. Two companies, Robocoin and Bitcoiniacs launched the world's first bitcoin ATM on 29 October 2013 in Vancouver, BC, Canada, allowing clients to sell or purchase bitcoin currency at a downtown coffee shop. Chinese internet giant Baidu had allowed clients of website security services to pay with bitcoins.
In November 2013, the University of Nicosia announced that it would be accepting bitcoin as payment for tuition fees, with the university's chief financial officer calling it the "gold of tomorrow". During November 2013, the China-based bitcoin exchange BTC China overtook the Japan-based Mt. Gox and the Europe-based Bitstamp to become the largest bitcoin trading exchange by trade volume.
In December 2013, Overstock.com announced plans to accept bitcoin in the second half of 2014. On 5 December 2013, the People's Bank of China prohibited Chinese financial institutions from using bitcoins. After the announcement, the value of bitcoins dropped, and Baidu no longer accepted bitcoins for certain services. Buying real-world goods with any virtual currency had been illegal in China since at least 2009.
2014
In January 2014, Zynga announced it was testing bitcoin for purchasing in-game assets in seven of its games. That same month, The D Las Vegas Casino Hotel and Golden Gate Hotel %story% Casino properties in downtown Las Vegas announced they would also begin accepting bitcoin, according to an article by USA Today. The article also stated the currency would be accepted in five locations, including the front desk and certain restaurants. The network rate exceeded 10 petahash/sec. TigerDirect and Overstock.com started accepting bitcoin.
In early February 2014, one of the largest bitcoin exchanges, Mt. Gox, suspended withdrawals citing technical issues. By the end of the month, Mt. Gox had filed for bankruptcy protection in Japan amid reports that 744,000 bitcoins had been stolen. Months before the filing, the popularity of Mt. Gox had waned as users experienced difficulties withdrawing funds.
In June 2014 the network exceeded 100 petahash/sec.[citation needed] On 18 June 2014, it was announced that bitcoin payment service provider BitPay would become the new sponsor of St. Petersburg Bowl under a two-year deal, renamed the Bitcoin St. Petersburg Bowl. Bitcoin was to be accepted for ticket and concession sales at the game as part of the sponsorship, and the sponsorship itself was also paid for using bitcoin.
In July 2014 Newegg and Dell started accepting bitcoin.
In September 2014 TeraExchange, LLC, received approval from the U.S.Commodity Futures Trading Commission "CFTC" to begin listing an over-the-counter swap product based on the price of a bitcoin. The CFTC swap product approval marks the first time a U.S. regulatory agency approved a bitcoin financial product.
In December 2014 Microsoft began to accept bitcoin to buy Xbox games and Windows software.
In 2014, several light-hearted songs celebrating bitcoin such as the "Ode to Satoshi" have been released.
A documentary film, The Rise and Rise of Bitcoin, was released in 2014, featuring interviews with bitcoin users, such as a computer programmer and a drug dealer.
2015
In January 2015 Coinbase raised US$75 million as part of a Series C funding round, smashing the previous record for a bitcoin company. Less than one year after the collapse of Mt. Gox, United Kingdom-based exchange Bitstamp announced that their exchange would be taken offline while they investigate a hack which resulted in about 19,000 bitcoins (equivalent to roughly US$5 million at that time) being stolen from their hot wallet. The exchange remained offline for several days amid speculation that customers had lost their funds. Bitstamp resumed trading on 9 January after increasing security measures and assuring customers that their account balances would not be impacted.
In February 2015, the number of merchants accepting bitcoin exceeded 100,000.
In October 2015, a proposal was submitted to the Unicode Consortium to add a code point for the bitcoin symbol.
2016
In January 2016, the network rate exceeded 1 exahash/sec.[citation needed]
In March 2016, the Cabinet of Japan recognized virtual currencies like bitcoin as having a function similar to real money. Bidorbuy, the largest South African online marketplace, launched bitcoin payments for both buyers and sellers.
In July 2016, researchers published a paper showing that by November 2013 bitcoin commerce was no longer driven by "sin" activities but instead by legitimate enterprises.
In August 2016, a major bitcoin exchange, Bitfinex, was hacked and nearly 120,000 BTC (around $60m) was stolen.
In November 2016, the Swiss Railway operator SBB (CFF) upgraded all their automated ticket machines so that bitcoin could be bought from them using the scanner on the ticket machine to scan the bitcoin address on a phone app.
Bitcoin generates more academic interest year after year; the number of Google Scholar articles published mentioning bitcoin grew from 83 in 2009, to 424 in 2012, and 3580 in 2016. Also, the academic journal Ledger published its first issue. It is edited by Peter Rizun.
2017
The number of businesses accepting bitcoin continued to increase. In January 2017, NHK reported the number of online stores accepting bitcoin in Japan had increased 4.6 times over the past year. BitPay CEO Stephen Pair declared the company's transaction rate grew 3× from January 2016 to February 2017, and explained usage of bitcoin is growing in B2B supply chain payments.
Bitcoin gains more legitimacy among lawmakers and legacy financial companies. For example, Japan passed a law to accept bitcoin as a legal payment method, and Russia has announced that it will legalize the use of cryptocurrencies such as bitcoin.
Exchange trading volumes continue to increase. For the 6-month period ending March 2017, Mexican exchange Bitso saw trading volume increase 1500%.[citation needed] Between January and May 2017 Poloniex saw an increase of more than 600% active traders online and regularly processed 640% more transactions.
In June 2017, the bitcoin symbol was encoded in Unicode version 10.0 at position U+20BF (₿) in the Currency Symbols block.
Up until July 2017, bitcoin users maintained a common set of rules for the cryptocurrency. On 1 August 2017 bitcoin split into two derivative digital currencies, the bitcoin (BTC) chain with 1 MB blocksize limit and the Bitcoin Cash (BCH) chain with 8 MB blocksize limit. The split has been called the Bitcoin Cash hard fork.
On 6 December 2017 the software marketplace Steam announced that it would no longer accept bitcoin as payment for its products, citing slow transactions speeds, price volatility, and high fees for transactions.
2018

On 22 January 2018, South Korea brought in a regulation that requires all the bitcoin traders to reveal their identity, thus putting a ban on anonymous trading of bitcoins.
On 24 January 2018, the online payment firm Stripe announced that it would phase out its support for bitcoin payments by late April 2018, citing declining demand, rising fees and longer transaction times as the reasons.
2019
As of September 2019, there were 5,457 bitcoin ATMs worldwide. In August of that year, the countries with highest number of bitcoin ATMs were the United States, Canada, the United Kingdom, Austria, and Spain.[citation needed]

купить ethereum Secondly, supply may also be impacted by the number of bitcoins the system allows to exist. This number is capped at 21 million, where once this number is reached, mining activities will no longer create new bitcoins. For example. the supply of bitcoin reached 18.1 million in December 2019, representing 86.2% of the supply of bitcoin that will ultimately be made available. Once 21 million bitcoins are in circulation, prices depend on whether it is considered practical (readily usable in transactions), legal, and in demand, which is determined by the popularity of other cryptocurrencies. The artificial inflation mechanism of the halving of block rewards will no longer have an impact on the price of the cryptocurrency. However, at the current rate of adjustment of block rewards, the last bitcoin is not set to be mined until the year 2140 or so.валюта bitcoin bitcoin cranes bitcoin network ethereum ubuntu store bitcoin bitcoin таблица bistler bitcoin ethereum addresses ethereum php краны monero bitcoin ethereum
bitcoin global But unless a node needs to execute every transaction or easily query historical data, there’s really no need to store the entire chain. This is where the concept of a light node comes in. Instead of downloading and storing the full chain and executing all of the transactions, light nodes download only the chain of headers, from the genesis block to the current head, without executing any transactions or retrieving any associated state. Because light nodes have access to block headers, which contain hashes of three tries, they can still easily generate and receive verifiable answers about transactions, events, balances, etc.advcash bitcoin bitcoin server bitcoin вход Network Observers – link different transactions and addresses together by observing activity on the peer to peer network.Typical fees are between 1% and around 3%.

Every account has a public key and a private key — both of which are long strings of numbers and letters. Your wallet software knows your private key, and this allows it to send money. To send money to someone, you merely need to know their public key (basically their bank account number). If you have your private key plus their public key, a transaction can be created and the funds are deducted from your account and credited to the receiver’s account, without anyone else having a say in the matter.кошель bitcoin bitcoin skrill bitcoin spinner bitcoin usa se*****256k1 ethereum подтверждение bitcoin bitcoin сбербанк bitcoin prosto bitcoin torrent капитализация ethereum remix ethereum instaforex bitcoin ethereum клиент работа bitcoin bitcoin genesis ethereum асик ethereum forks fasterclick bitcoin взлом bitcoin

4. What is a Blockchain Wallet?addnode bitcoin Bitcoin (₿) is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency, as the system works without a central bank or single administrator. The system was designed to work as a peer-to-peer network, a network in which transactions take place between users directly, without an intermediary. These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto and released as open-source software in 2009.фермы bitcoin обмен ethereum future bitcoin importprivkey bitcoin nvidia bitcoin смысл bitcoin short bitcoin проекта ethereum local bitcoin cryptocurrency analytics
