GPU mining rewards go to individuals worldwide, instead of mostly to ASIC warehouse owners, recreating network effects that Bitcoin used to have. [\\[1\\]](#cite-id-ze9wxtqbrq)  \n$$widget0 [YOUTUBE@VID](aTYZ0J0zuzo)$$  \nBitcoin Gold was [hard forked](https://iq.wiki/wiki/hard-fork) from the [Bitcoin](https://iq.wiki/wiki/bitcoin) blockchain on October 24, 2017, at block height 491407. The aim was to create an ASIC-resistant version of [Bitcoin](https://iq.wiki/wiki/bitcoin) to decentralize the network, addressing the concentration of mining power. The concept behind Bitcoin Gold was \"one CPU one vote,\" reflecting [Satoshi Nakamoto’s](https://iq.wiki/wiki/satoshi-nakamoto) original vision where every node could [mine](https://iq.wiki/wiki/mining) coins. [\\[1\\]](#cite-id-ze9wxtqbrq)[\\[5\\]](#cite-id-vymsmza3eli)  \n  \n# Tokenomics  \n  \nBitcoin Gold has a total supply of 21,000,000 BTG tokens. Out of the total amount of BTG tokens, 30% went towards the development of the blockchain and the project. Another 15% was reserved for ecosystem support and development, and another 15% was distributed amongst the BTG community. [\\[3\\]](#cite-id-2nivk6luoa7)  \n  \nAbout 20% of the total BTG token supply was reserved for yearly expenses. Close to 7% of BTG tokens were set aside for bounties and app collaboration, while another 5% went towards rewards for the founding team. The remaining 8% of tokens went towards covering pre-fork costs and community development. [\\[3\\]](#cite-id-2nivk6luoa7)[\\[4\\]](#cite-id-a7wtb2simjj)  \n  \n# Network Attacks  \n  \nSoon after the launch, the Bitcoin Gold website experienced a distributed denial of service ([DDoS](https://iq.wiki/wiki/distributed-denial-of-service-ddos-attack)) attack and received criticism from [Coinbase](https://iq.wiki/wiki/coinbase) and Bittrex for being hastily put together, as well as including a developer pre-mine. [\\[6\\]](#cite-id-cuz49lov5ot)  \n  \nIn May 2018, Bitcoin Gold experienced a 51% hashing attack by an unknown actor, allowing manipulation of the [blockchain](https://iq.wiki/wiki/blockchain) ledger and double-spending of digital coins. During this attack, approximately 388,000 BTG (worth around US$18 million) was stolen from several cryptocurrency [exchanges](https://iq.wiki/wiki/decentralized-exchange). The BTG team said the hack was a combination of a [51% attack](https://iq.wiki/wiki/51percent-attack) and a double-spend attack. Subsequently, Bitcoin Gold was delisted from Bittrex after the team declined to contribute to damages. [\\[7\\]](#cite-id-kxlaz41ypu)  \n  \n# Team  \n  \n* [Jack Liao](https://iq.wiki/wiki/jack-liao) \\- Founder[\\[12\\]](#cite-id-nwjrb79dbvq)  \n* H4X3ROTAB - Lead Developer[\\[8\\]](#cite-id-ihokoft07g)  \n* Martin Kuvandzhiev - Operations Lead[\\[9\\]](#cite-id-gpzlre9g7jj)  \n* Franco Niebles - Lead Designer[\\[10\\]](#cite-id-ogaso4j15c)  \n* Edward Iskra - Communications Director[\\[11\\]](#cite-id-jc9ueivc7oc)","summary":"Bitcoin Gold (BTG) is a hard fork of Bitcoin designed for decentralized GPU mining, eliminating ASIC dominance and reflecting Satoshi Nakamoto’s original vision...","categories":[{"id":"cryptocurrencies","title":"Cryptocurrencies"}],"promoted":0,"tags":[{"id":"Glossary"}],"metadata":[{"id":"references","value":"[{\"id\":\"ze9wxtqbrq\",\"url\":\"https://bitcoingold.org/\",\"description\":\"Bitcoin Gold Website\",\"timestamp\":1660293883299},{\"id\":\"tzshk2b1r4j\",\"url\":\"https://twitter.com/bitcoingold\",\"description\":\"Bitcoin Gold on Twitter\",\"timestamp\":1660293908177},{\"id\":\"2nivk6luoa7\",\"url\":\"https://coinmarketcap.com/currencies/bitcoin-gold/\",\"description\":\"coinmarketcap - bitcoin gold\",\"timestamp\":1660294198209},{\"id\":\"a7wtb2simjj\",\"url\":\"https://www.coingecko.com/en/coins/bitcoin-gold\",\"description\":\"coingecko - bitcoin gold\",\"timestamp\":1722008628169},{\"id\":\"vymsmza3eli\",\"url\":\"https://crypto.bi/jack-liao/\",\"description\":\"crypto bi - btc gold\",\"timestamp\":1722009499400},{\"id\":\"cuz49lov5ot\",\"url\":\"https://mashable.com/article/bitcoin-fork-bitcoin-gold\",\"description\":\"Bitcoin splits into two again, but owners don't get free money just yet\",\"timestamp\":1722009757004},{\"id\":\"kxlaz41ypu\",\"url\":\"https://www.zdnet.com/article/bitcoin-gold-delisted-from-major-cryptocurrency-exchange-after-refusing-to-pay-hack-damages/\",\"description\":\"Bitcoin Gold delisted from major cryptocurrency exchange...\",\"timestamp\":1722009889187},{\"id\":\"ihokoft07g\",\"url\":\"https://twitter.com/bgmshana\",\"description\":\"H4X3ROTAB\",\"timestamp\":1722011195561},{\"id\":\"gpzlre9g7jj\",\"url\":\"https://twitter.com/MKuvandzhiev\",\"description\":\"MARTIN KUVANDZHIEV\",\"timestamp\":1722011239624},{\"id\":\"ogaso4j15c\",\"url\":\"https://twitter.com/franconiebles\",\"description\":\"FRANCO NIEBLES\\n\",\"timestamp\":1722011272396},{\"id\":\"jc9ueivc7oc\",\"url\":\"https://twitter.com/MentalNomadSays\",\"description\":\"EDWARD ISKRA\",\"timestamp\":1722011332123},{\"id\":\"nwjrb79dbvq\",\"url\":\"https://bitcoingold.org/our-team/\",\"description\":\"team website\",\"timestamp\":1722011454614}]"},{"id":"website","value":"https://bitcoingold.org/"},{"id":"facebook_profile","value":"https://www.facebook.com/bitcoingoldofficial/"},{"id":"twitter_profile","value":"https://x.com/bitcoingold"},{"id":"youtube_profile","value":"https://www.youtube.com/channel/UCmYIP4GQdsBIevQtx8k6Bcw"},{"id":"discord_profile","value":"https://discord.gg/HmVUU6S"},{"id":"reddit_profile","value":"https://www.reddit.com/r/BitcoinGoldHQ"},{"id":"telegram_profile","value":"https://t.me/BitcoinGoldHQ"},{"id":"github_profile","value":"https://github.com/BTCGPU/BTCGPU"},{"id":"coinmarketcap_url","value":"https://coinmarketcap.com/currencies/bitcoin-gold/"},{"id":"coingecko_profile","value":"https://www.coingecko.com/en/coins/bitcoin-gold"},{"id":"previous_cid","value":"QmTH2qJzWadqTtdSsBvJtYfL7bdNvy5QbgsxgYNCuG3QAV"}],"user":{"id":"0x6753061a4cffbc0A617e57E956A298D88702a94B"},"author":{"id":"0x7da121Af2c3Fc2e65eDCD3573a403C352B4538Aa","profile":{"username":"Ilori_Josh","avatar":"QmVG5Mp6f1NeZ4xEwqS2jh75tjqiF9su8xCRVWrsnv2RFA"}},"media":[{"name":"MWSkNAjl1Ik","id":"https://www.youtube.com/watch?v=MWSkNAjl1Ik","size":"0","type":null,"source":"YOUTUBE"},{"name":"aTYZ0J0zuzo","id":"https://www.youtube.com/watch?v=aTYZ0J0zuzo","size":"0","type":null,"source":"YOUTUBE"}],"views":369,"events":[{"title":"BTG Launch","description":"BTG Launch","link":"https://www.coindesk.com/markets/2017/11/09/bitcoin-gold-sets-sunday-date-for-cryptocurrency-release/","date":"2017-11","type":"CREATED"}],"linkedWikis":{"founders":["jack-liao"],"blockchains":["bitcoin"]},"founderWikis":[{"id":"jack-liao","title":"Jack Liao"}],"blockchainWikis":[{"id":"bitcoin","title":"Bitcoin"}],"ipfs":"QmTH2qJzWadqTtdSsBvJtYfL7bdNvy5QbgsxgYNCuG3QAV","transactionHash":"0x164523f652accf3a9e21cec2738b8da04b57cafd9c1ff2f8a8c2cd6d5e8b2dd3","created":"2022-08-12T08:50:52.595Z","updated":"2024-08-12T19:12:05.035Z","images":[{"id":"QmcwAidChoi1ftAoLNUwvGuaSJgJC7xvVvaxpXwk5eBB1q","type":"image/jpeg, image/png"}]}
