If it doesn't need historical operations then why does it need a blockchain? What makes it different to other coins? Does it have a blockchain pruning mechanism to keep the blockchain small, or some special features besides being written in a different language to other coins?
It's explained in the White Paper. The BlockChain is used to create and mantain a "Safe Box". In any moment, you can delete the blockchain because you only need the Safe Box to work and operate (control double spend, check balance, confirm signatures...)
