What is Bitcoin?

Bitcoin is a form of digital currency, created and held electronically. No one controls it. Bitcoins aren’t printed, like dollars or euros – they’re produced by people, and increasingly businesses, running computers all around the world, using software that solves mathematical problems.
It’s the first example of a growing category of money known as cryptocurrency.

What makes it different from normal currencies?

Bitcoin can be used to buy things electronically. In that sense, it’s like conventional dollars, euros, or yen, which are also traded digitally.
However, bitcoin’s most important characteristic, and the thing that makes it different to conventional money, is that it is decentralized. No single institution controls the bitcoin network. This puts some people at ease, because it means that a large bank can’t control their money.

Who created it?

A software developer called Satoshi Nakamoto proposed bitcoin, which was an electronic payment system based on mathematical proof. The idea was to produce a currency independent of any central authority, transferable electronically, more or less instantly, with very low transaction fees.

Who prints it?

No one. This currency isn’t physically printed in the shadows by a central bank, unaccountable to the population, and making its own rules. Those banks can simply produce more money to cover the national debt, thus devaluing their currency.
Instead, bitcoin is created digitally, by a community of people that anyone can join. Bitcoins are ‘mined’, using computing power in a distributed network.
This network also processes transactions made with the virtual currency, effectively making bitcoin its own payment network.

So you can’t churn out unlimited bitcoins?

That’s right. The bitcoin protocol – the rules that make bitcoin work – say that only 21 million bitcoins can ever be created by miners. However, these coins can be divided into smaller parts (the smallest divisible amount is one hundred millionth of a bitcoin and is called a ‘Satoshi’, after the founder of bitcoin).

What is bitcoin based on?

Conventional currency has been based on gold or silver. Theoretically, you knew that if you handed over a dollar at the bank, you could get some gold back (although this didn’t actually work in practice). But bitcoin isn’t based on gold; it’s based on mathematics.
Around the world, people are using software programs that follow a mathematical formula to produce bitcoins. The mathematical formula is freely available, so that anyone can check it.
The software is also open source, meaning that anyone can look at it to make sure that it does what it is supposed to.

What are its characteristics?

Bitcoin has several important features that set it apart from government-backed currencies.

1. It's decentralized

The bitcoin network isn’t controlled by one central authority. Every machine that mines bitcoin and processes transactions makes up a part of the network, and the machines work together. That means that, in theory, one central authority can’t tinker with monetary policy and cause a meltdown – or simply decide to take people’s bitcoins away from them, as the Central European Bank decided to doin Cyprus in early 2013. And if some part of the network goes offline for some reason, the money keeps on flowing.

2. It's easy to set up

Conventional banks make you jump through hoops simply to open a bank account. Setting up merchant accounts for payment is another Kafkaesque task, beset by bureaucracy. However, you can set up a bitcoin address in seconds, no questions asked, and with no fees payable.

3. It's anonymous

Well, kind of. Users can hold multiple bitcoin addresses, and they aren’t linked to names, addresses, or other personally identifying information. However…

4. It's completely transparent

…bitcoin stores details of every single transaction that ever happened in the network in a huge version of a general ledger, called the blockchain. The blockchain tells all.
If you have a publicly used bitcoin address, anyone can tell how many bitcoins are stored at that address. They just don’t know that it’s yours.
There are measures that people can take to make their activities more opaque on the bitcoin network, though, such as not using the same bitcoin addresses consistently, and not transferring lots of bitcoin to a single address.

5. Transaction fees are miniscule

Your bank may charge you a £10 fee for international transfers. Bitcoin doesn’t.

6. It’s fast

You can send money anywhere and it will arrive minutes later, as soon as the bitcoin network processes the payment.

7. It’s non-repudiable

When your bitcoins are sent, there’s no getting them back, unless the recipient returns them to you. They’re gone forever.
So, bitcoin has a lot going for it, in theory. But how does it work, in practice? Read more to find out how bitcoins are mined, what happens when a bitcoin transaction occurs, and how the network keeps track of everything.

How Blockchain Could Help Tech Giant Cisco Reboot

Cisco is changing. The technology firm best known as the supplier of enterprise computer hardware has seen a slow, steady decline in revenue from some of its core products. As a result of an increasing number technological services being virtualized, and the storage of information moving to the cloud, the $158bn firm has been  restructuring  and exploring new ways to capitalize on connected devices. But amidst this change in identity, it's in identity itself where some of the California-based company's most interesting new experiments are taking place. With a series of early stage blockchain  projects , Cisco is now pushing even deeper into what could end up being much more than a way for employees to prove who they are across subsidiaries. In conversation with CoinDesk, Robert Greenfield IV, Cisco software engineer and executive team lead of the firm's Connected Black Professionals resource group, explained how several blockchain projects have evolv...

Bitcoin in Africa: Insights from the Continent’s Biggest Bitcoin Exchange

Isn’t it absurd that nearly 326 million people representing 80% of the adult population in Africa do not have access to bank accounts? This wretched situation denies countless of people financial freedom in the so-called dark continent. Bureaucratic tenors and economic exclusion inter alia have paved the way for the current phenomenon. Last year a study of 10 African nations with unusual inflationary ratio had South Sudan registering an unimaginable inflation rate of 295 percent. Egypt had the slightest with 12.30 percent. African governments continue to plunder the riches of the African people through Inflation. This makes it considerably insurmountable for individuals to conserve their resources. Moreover, public sector borrowing has crowded out the efficient private sector that can put credit to good use. The IMF estimates that averagely credit to the private sector is estimated at 30 percent of GDP in Sub-Sahara Africa. CCN spoke to Werner van Rooyen, Head of Business Develo...
