Burstcoin is a digital cryptographic currency and payment system based on the blockchain technology. Burstcoin was introduced on the bitcointalk.org forum on 10 August 2014 as an Nxt-based currency. Burstcoins are mined using an algorithm called proof-of-capacity (PoC)[note 1] in which miners use computer storage instead of the more common energy-expensive method of permanent complex computational calculations.
