HBBFT and PoST: what is better? ⚖️ ⠀ Proof-of-Space and Time is a new consensus algorithm: to mine new blocks you need to prove that you spent some time keeping the reserved space unchanged. The cost of storage is related not only to the capacity but also to the time during which this capacity is used. ⠀ This algorithm has become popular for the reason that mining requires not only computing power but also free space on the drive. During the period of shortage of graphics cards, this concept is a real salvation for some. ⠀ At the same time, an important point is that for effective mining it is necessary to use an SSD. This type of drive has a very small write-overwrite cycle, which quickly SSD them out of use. ⠀ The Honey Badger Byzantine Fault Tolerant consensus algorithm does not require the user to purchase any kind of specialized hardware normal servers can run as a validator candidate node. ⠀ Since it does require minimal computing power (~100-200w for a validator candidate node), it does not affect the environment in any way, and a distinctive feature of the algorithm is the ability to form a block almost instantly. ⠀ Therefore, HBBFT is a much more environment-friendly, economical, and reliable consensus algorithm than the newly popular Proof-of-Space and Time technology.
