## What Is Bitcoin Gold (BTG)?

Bitcoin Gold was founded in 2017 to become a user-friendly alternative to [Bitcoin](https://coinmarketcap.com/currencies/bitcoin/). The BTG network aims to combine the security and sturdiness of the Bitcoin [blockchain](https://coinmarketcap.com/alexandria/glossary/blockchain) and its characteristics with the opportunity for experimentation and development. 

BTG enhances and extends the crypto space with a blockchain closely compatible with Bitcoin but without using resources like Bitcoin hash power or vying for the "real Bitcoin" title. The company aims to present a coin with the implementation capabilities of Bitcoin, however, expanding on the opportunities for DeFi and DApp developers to use the coin.

#### What Makes Bitcoin Gold Unique?

Bitcoin Gold is a unique combination of the inherent properties of the original Bitcoin blockchain and an innovative approach to blockchain development and applications. As a hard fork of the original Bitcoin token, BTG aims to revolutionize the mining process by introducing a new proof-of-work algorithm that combats the scalability issues Bitcoin struggles with. 

As an open-source protocol, Bitcoin Gold allows developers to participate in the governance and development of the blockchain freely. According to the company, this is a must-have requirement for pushing decentralization and one of the major points where Bitcoin struggles. 

Bitcoin Gold is one of the first hard forks of the original cryptocurrency, which has attracted institutional and enterprise investors’ attention. BTG is available on a wide variety of exchanges, as well as swap services and wallets. Lastly, Bitcoin Gold has been actively adopted by several online browsers and service providers.

### How Is the Bitcoin Gold Network Secured?

As a Bitcoin hard fork, Bitcoin Gold relies on the proof-of-work ([PoW](https://coinmarketcap.com/alexandria/glossary/proof-of-work-pow)) consensus mechanism. However, one of BTG’s main goals was to revolutionize the mining process by introducing the Equihash PoW, which favors [GPUs](https://coinmarketcap.com/alexandria/glossary/graphical-processing-unit-gpu) for mining, unlike the Bitcoin blockchain. 

While Bitcoin relies predominantly on application-specific integrated circuit ([ASIC](https://coinmarketcap.com/alexandria/glossary/asic)) miners, This version of Equihash uses more memory than an ASIC can offer but runs fine on many graphics cards. Unlike the [Ethereum](https://coinmarketcap.com/currencies/ethereum/) blockchain, which relies on the proof-of-stake ([PoS](https://coinmarketcap.com/alexandria/glossary/proof-of-stake-pos)) mechanism and favors stakeholders, Bitcoin Gold places importance on the processing power miners have.
