Burst is a bit different. you need hard drives to mine it.

They store the result of using the shabal algorithm 4096 times on a nonce and an account id to generate a deadline.

Its called Proof Of Capacity but i call it Proof Of Luck where by the more hard drive space you have the more lucky you are to hit decent deadlines

It then re scans the drive every block using new parameters which changes the deadline. a factor is the network difficulty.
