Bitcoin Cash is a hard fork of Bitcoin with a protocol upgrade to fix on-chain capacity. Bitcoin Cash intends to be a Bitcoin without Segregated Witness (SegWit) as soft fork, where upgrades of the protocol are done mainly through hard forks and without changing the original economic rules of the Bitcoin. Bitcoin Cash (BCH) is released on 1st August 2017 as an upgraded version of the original Bitcoin Core software. The main upgrade is the increase in the block size limit from 1MB to 8MB. This effectively allows miners on the BCH chain to process up to 8 times more payments per second in comparison to Bitcoin. This makes for faster, cheaper transactions and a much smoother user experience. Why was Bitcoin Cash Created? The main objective of Bitcoin Cash is to to bring back the essential qualities of money inherent in the original Bitcoin software. Over the years, these qualities were filtered out of Bitcoin Core and progress was stifled by various people, organizations, and companies involved in Bitcoin protocol development. The result is that Bitcoin Core is currently unusable as money due to increasingly high fees per transactions and transfer times taking hours to complete. This is all because of the 1MB limitation of Bitcoin Core’s block size, causing it unable to accommodate to large number of transactions. Essentially Bitcoin Cash is a community-activated upgrade (otherwise known as a hard fork) of Bitcoin that increased the block size to 8MB, solving the scaling issues that plague Bitcoin Core today.

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.
