Bitcoin is a type of digital currency, created and held electronically. nobody controls it. Bitcoins aren’t printed, like bucks or euros – they’re created by individuals, and more and more businesses, running computers all round the world, exploitation software system that solves mathematical issues.
It’s the primary example of a growing class of cash called cryptocurrency.
What makes it different from traditional currencies?
Bitcoin are often used to purchase things electronically. in this sense, it’s like standard bucks, euros, or yen, that also are traded digitally.
However, bitcoin’s most vital characteristic, and also the factor that creates it completely different to standard cash, is that it's decentralised. No single establishment controls the bitcoin network. This puts some individuals comfortable, as a result of it means an oversized bank can’t management their cash.
Who created it?
A software system developer known as Satoshi Nakamoto projected bitcoin, that was an electronic payment system based on mathematical proof. the idea was to supply a currency independent of any central authority, transferable electronically, more or less instantly, with terribly low dealings fees.
Who prints it?
No one. This currency isn’t physically printed within the shadows by a financial organisation, unaccountable to the population, and making its own rules. Those banks can just manufacture extra money to hide the debt, therefore devaluing their currency.
Instead, bitcoin is formed digitally, by a community of individuals that anyone will be part of. Bitcoins are ‘mined’, using computing power in a very distributed network.
This network additionally processes transactions created with the virtual currency, effectively creating bitcoin its own payment network.
So you can’t churn out unlimited bitcoins?
That’s right. The bitcoin protocol – the principles that make bitcoin work – say that only twenty one million bitcoins will ever be created by miners. However, these coins may be divided into smaller elements (the smallest separable quantity is 100 millionth of a bitcoin and is termed a ‘Satoshi’, after the founding father of bitcoin).
What is bitcoin based on?
Conventional currency has been supported by gold or silver. in theory, you knew that if you handed over a dollar at the bank, you'll get some gold back (although this didn’t truly work in practice). however bitcoin isn’t supported by gold; it’s based on arithmetic.
Around the world, individuals are exploitation software system programs that follow a mathematical formula to provide bitcoins. The mathematical formula is freely accessible, so anyone can check it.
The software system is additionally open source, which means that anyone can check out it to make certain that it does what it's presupposed to.
What are its characteristics?
Bitcoin has many vital options that set it aside from government-backed currencies.
1. It's decentralised
The bitcoin network isn’t controlled by one central authority. each machine that mines bitcoin and processes transactions makes up a section of the network, and therefore the machines work along. meaning that, in theory, one central authority can’t tinker with financial policy and cause a meltdown – or just attempt to take people’s bitcoins far from them, because the Central European Bank determined to try to to in Cyprus in early 2013. And if some a part of the network goes offline for some reason, the cash keeps on flowing.
2. It is easy to set up
Conventional banks cause you to jump through hoops simply to open a checking account. putting in place bourgeois accounts for payment is another Kafkaesque task, beset by forms. However, you'll be able to originated a bitcoin address in seconds, no queries asked, and with no fees owed.
3. It is anonymous
Well, kind of. Users can hold multiple bitcoin addresses, and that they aren’t connected to names, addresses, or alternative personally identifying info. However…
4. It's fully transparent
…bitcoin stores details of each single transaction that ever happened within the network in a very large version of a account book, referred to as the blockchain. The blockchain tells all.
If you've got a publically used bitcoin address, anyone will tell what percentage bitcoins are hold on at that address. they only don’t know that it’s yours.
There are measures that folks will fancy create their activities a lot of opaque on the bitcoin network, though, like not using identical bitcoin addresses systematically, and not transferring numerous bitcoin to one address.
5. Transaction fees are very small
Your bank might charge you a £10 fee for international transfers. Bitcoin doesn’t.
6. It is fast
You can send cash anywhere and it'll arrive minutes later, as shortly because the bitcoin network processes the payment.
7. It is non-repudiable
When your bitcoins are sent, there’s no obtaining them back, unless the recipient returns them to you. They’re gone forever.
So, bitcoin features a ton going for it, in theory. but how will it work, in practice? read more to find out however bitcoins are mined, what happens once a bitcoin transaction happens, and the way the network keeps track of everything.
