Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons).
After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc).
Bitcoin's underlying technology is called Blockchain.
The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block.

Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application.
New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum.
Ethereum focuses on running programming code, called smart contracts, on any...

Double-spending is an error in a digital cash scheme in which the same single digital token is spent twice or more.

As with counterfeit money, such double-spending is Inflation by creating, during the duplication or falsification of the digital file, a new amount of currency that hadn't existed prior to that time. This devalues the currency relative to other monetary units, and diminishes user trust as well as the circulation and retention of the currency. Fundamental cryptographic techniques to prevent double-spending while preserving anonymity in a transaction are blind signatures and particularly in offline systems, secret splitting.

The prevention of double-spending has taken two general forms: centralized and decentralized.

This is usually implemented using an on-line...

This is educational video series explaining common stumble blocks and misconceptions about Bitcoin!

And just in case for the minimal chance that you would like to tip me, here is my bitcoin address :)

Here is a transcript of the video:
First lets get our facts straight.
Bitcoin transactions are not slow, infact they are INSTANT! But confirmations take 10 minutes on average.
A double spend is an attack where the same bitcoin is sent to two different receivers, effectively defrauding one of them, since only 1 can get the coin for real. And the confirmation is supposed to take care of that problem because confirmation is a process during which the network checks if that bitcoin, has NOT been spent already.
So, after the first confirmation the risk of double spending is small and decreases exponentially with every next confirmation. Making it harder and more expensive for an attacker to execute it.

But who wants to wait 10 minutes to SAFELY pay for a coffee? Well that's not...
