The first altcoin that was introduced to the market of cryptocurrency is Namecoin. It was created in april 2011 right after the creation of bitcoin.
It is one of the ten altcoins,the intention of namecoin's creation was to decentralize domain registrations.
Namecoin is still among successful altcoins and can be also used as a digital currency payment purpose.
Till now I thought it was litecoin. Just curious, Is namecoin anyway related to namecheap?
It's always like that. For example, you would thinkg that Chuck Berry was the inventor of Rock'n'roll in it's true meaning, but then you find out there were many less known guys playing those same things before them and that even his most famous riff was borrowed. In any case, he took it to a completely new level, nothing wrong with that, still a legend for me and I am very happy I had the opportunity to see him playing live.
To cut the story short - you can always expect something nameless to be "the first". Even Bitcoin was not the first cryptocurrency. There was Hashcash and a few others. Different in technology, different purpose, but very similar in it's nature.
