Users can employ unused hard disk capacity to mine Bitcoins without the need for expensive mining rigs and other specialized hardware. Traditional mining hardware is energy intensive, noisy, produces a lot of heat, and is becoming increasingly specialized, moving beyond the means of ordinary people. With BHD, mining is simple and accessible. POW-based mining is all about raw computing power and energy output, whereas BHD's POC-based mining is far more energy efficient and returns to Satoshi Nakamoto’s original ideal that mining would be decentralized and performed by ordinary people. POC (Proof of Capacity) scans are only performed once every few minutes. For the rest of the time the hard disk is on stand-by with negligible power usage, greatly reducing energy costs. Based on capacity proof, it will support super-large blocks in the future and will add functions such as zero-knowledge proof. Solid-state drives are expensive, POC has no requirement for fast data processing, only capacity, so POC naturally eliminates ASIC chips. Currently, the amount of energy expended globally in POW mining is greater than the total energy output of 159 countries. The development of digital currencies shouldn’t have to be built on the wasting of resources. With BHD, POW calculations can be completed with a minimum of computing and energy resources.
Gas is one of the two coins created by Neo Foundation. Gas is used as a processing fees for Neo coin. Neo hashing algorithm is Proof of Stake (PoS), where blocks processing power depends on the amount of tokens held by miners instead of the Proof of Work method which depends on the mining power that a miner has to create a new block. Neo holders is compensated with certain amount of Gas every month, is a similar concept to the ether gas and is used as a power for transaction (transaction). It is a coin that is paid as compensation of a concept of interest generated by PoS mining. At the beginning of the release, about one Neo was paid per day with 1000 Neo, but it has a design algorithm that is gradually decreasing over time, which is offset by the price increase. It is a coin that is closely related to Neo, walking along the path of the companion with the rise of Neo, and it forms a necessary relationship that the movement must be moving in a fluid manner.
