History

edit

Primecoin was launched in 2013 by Sunny King, who also founded Peercoin.[2][3]

Unlike other cryptocurrencies, which are mined using algorithms that solved mathematical problems with no extrinsic value, mining Primecoin involves producing chains of prime numbers (Cunningham and bi-twin chains). These are useful to scientists and mathematicians and meet the requirements for a proof of work system of being hard to compute but easy to verify and having an adjustable difficulty.[4][1][2][5][3][6]

Shortly after its launch, some trade journals reported that the rush of over 18,000 new users seeking to mine Primecoin overwhelmed providers of dedicated servers.[1][7] It was ranked as being one of the top ten currencies before 2014.[8]

Primecoin has a block time of one minute, changes difficulty every block, and has a block reward that is a function of the difficulty.[2][6]
