Similar to Bitcoin, Terracoin launched in 2012, attempting to do all the things Bitcoin can do, but better – mainly faster transaction times and improved security.
Personally, we think Bitcoin’s security is just fine, but Terracoin did carve out a space for itself. It currently still has 800 members of their subreddit, nearly 10 years later.
It “improved security” by merging mining and dark gravity wave difficulty recalculation. If that last sentence makes sense to you, congratulations, would you like a job?
