Bitcoin is the first successful internet money based on peer-to-peer technology; whereby no central bank or authority is involved in the transaction and production of the Bitcoin currency. It was created by an anonymous individual/group under the name, Satoshi Nakamoto. The source code is available publicly as an open source project, anybody can look at it and be part of the developmental process. Bitcoin is changing the way we see money as we speak. The idea was to produce a means of exchange, independent of any central authority, that could be transferred electronically in a secure, verifiable and immutable way. It is a decentralized peer-to-peer internet currency making mobile payment easy, very low transaction fees, protects your identity, and it works anywhere all the time with no central authority and banks. Bitcoin is design to have only 21 million BTC ever created, thus making it a deflationary currency. Bitcoin uses the SHA-256 hashing algorithm with an average transaction confirmation time of 10 minutes. Miners today are mining Bitcoin using ASIC chip dedicated to only mining Bitcoin, and the hash rate has shot up to peta hashes. Being the first successful online cryptography currency, Bitcoin has inspired other alternative currencies such as Litecoin, Peercoin, Primecoin, and so on. The cryptocurrency then took off with the innovation of the turing-complete smart contract by Ethereum which led to the development of other amazing projects such as EOS, Tron, and even crypto-collectibles such as CryptoKitties.
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.
