Bihu consists of two main components: an identity system and a community for crypto investors. Bihu ID(bihu.com)is a self-sovereign ID system based on blockchain technology and decentralized storage. It aims to be the gate keeper for Web3.0, in order to protect users’ wealth, data and privacy. Bihu ID strives to be the 'KEY to Digital Liberty'. Bihu Community is an platform for crypto investors to share and obtain token-investment-related information. It will the first use case for Bihu ID. KEY is the utility token for both Bihu ID and Bihu Community. It is an ERC20 token on the Ethereum blockchain. KEY is used to incentivize content generation within the Bihu Community, as well as the primary method for good content discovery. KEY also is the value exchange method within the Bihu Community, such as tipping between users. Since a single Bihu ID lives on multiple blockchains, it is desired that users will be able to pay KEY for generic network fees (AKA gas). KEY also acts as the generic payment method in the Bihu ID system, for instance, to recover lost IDs.
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.
