This account of bitcoin history resumes the first ten-years - of the cryptocurrency. Bitcoin price since to Bitcoin price charts. 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. Adam Back developed hashcash, a proof-of-work scheme for spam control. The first proposals for distributed digital scarcity based cryptocurrencies were Wei Dai 's b-money and Nick Szabo's bit gold.
In the bit gold proposal which proposed a collectible market based mechanism for inflation control, Nick Szabo also investigated some additional enabling aspects including a Byzantine fault-tolerant asset registry to store and transfer the chained proof-of-work solutions.
The possibility that Satoshi Nakamoto was a computer collective in the European financial sector has also been discussed. On the 9th of November, the Bitcoin project was registered at the open-source-projects community resource, SourceForge.
In January , the bitcoin network came into existence with the release of the first open source bitcoin client and the issuance of the first bitcoins, with Satoshi Nakamoto mining the first block of bitcoins ever known as the genesis block , which had a reward of 50 bitcoins.
Embedded in the coinbase of this block was the text:. One of the first supporters, adopters, contributor 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. Other early supporters were Wei Dai, creator of bitcoin predecessor b-money , and Nick Szabo, creator of bitcoin predecessor bit gold.
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. How much was bitcoin worth in ? It is one of the most popular questions about the history Bitcoin.
The value of the first bitcoin transactions were negotiated by individuals on the bitcoin forum with one notable transaction of 10, BTC used to indirectly purchase two pizzas delivered by Papa John's. This was the only major security flaw found and exploited in bitcoin's history. The Electronic Frontier Foundation, a non-profit group, started accepting bitcoins in January , then stopped accepting them in June , citing concerns about a lack of legal precedent about new currency systems.
The EFF's decision was reversed on 17 May when they resumed accepting bitcoin. In January , 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".
A documentary film, The Rise and Rise of Bitcoin , was released in , featuring interviews with bitcoin users, such as a computer programmer and a drug dealer. In , several lighthearted songs celebrating bitcoin such as the Ode to Satoshi have been released.
The history and future of Bitcoin generates more academic interest year after year; the number of Google Scholar articles published mentioning bitcoin grew from 83 in , to in , and to in Also, the academic Ledger Journal published its first issue.
So, yes. It is not that easy to just change the code. As the network grows, it just gets exponentially harder to do so. There are many speculations regarding that. With every halving as well, technically the worth of circulating bitcoins left tends to spike, indicating a rush of interest in the ever-declining supply of BTC, However, an ultimate end to the reward mechanism may have interesting implications. Once all the bitcoins have been mined, transaction fees will be the sole source of income for miners.
The main concern, then, is whether or not transaction fees will be enough to keep miners financially afloat. Since rewards are partially what motivates a node to continue to validate transactions apart from mining fees, it is among the speculation that miner concentration may reduce or adversely, the mining fees may increase discouraging users to continue to transact in BTC.
However, it is not necessary that the end of supply must mark negative consequences. With a known limited supply of the cryptocurrency, it can appreciate in value and become a safe-haven investment falling in the basket of investment vehicles like gold and other precious metals.
It is also possible that developers might agree to unanimously increase the supply to maintain the stability of the network. It sure is a farfetched thought, over years to be exact, to speculate on the situation that would arise because of depleted supply of Bitcoin, but it definitely gives rise to interesting theories.

It is hard to know for sure, though. New blocks are added approximately every 10 minutes. The further out we try to predict when specific halvings will occur, the harder it is. Over years, a lot can change, and so it may happen sooner or later, perhaps even by more than year. The block reward will be a mere 0. Currently the block reward is 6. There are 30 more halvings before it goes to 0.
If we divide 6. Right now, miners earn most of their income via the block reward. When all 21 million bitcoins are mined, there won't be a block reward to pay to miners. When a Bitcoin user sends a BTC transaction, a small fee is attached. These fees go to miners and this is what will be used to pay miners instead of the block reward.
There are BTC left to be mined until the next block reward halving. So they are well beyond Bitcoin billionaires! At the time of writing, there are a little over 57 million litecoin LTC in existence. The Litecoin block halving is projected to be in August Most coins are exact copies of Bitcoin's source code.
Bcash is a fork of Bitcoin with a few things taken out. Litecoin is also a fork of Bitcoin with the block time and mining algorithm changed. There are a little over million ether ETH in existence. There is no real cap on the total number of ETH than can come into existence like there is with Bitcoin.
Eth is not a fork or clone of Bitcoin like Litecoin is.
