decentralized margin trading and lending protocol founded in 2017 by Tom Bean and Kyle Kistner. The protocol suffered four separate security incidents between 2020 and 2021, culminating in a ~$55 million hack attributed to a phishing-induced private key compromise. Following a transfer of control to a DAO structure, the successor Ooki DAO was sued by the CFTC for operating an unregistered derivatives exchange, ultimately receiving a default judgment, trading bans, and a court-ordered shutdown in June 2023.","timeline":[{"date":"2017-08","event":"Tom Bean and Kyle Kistner conceive bZx Protocol after reading 0x, Kyber, and Bancor whitepapers.","source":"Decrypt / bZx team interviews","source_url":"https://decrypt.co/resources/bzx-ethereum-defi-decentralized-finance-explained-guide"},{"date":"2018-02","event":"bZx whitepaper published.","source":"bZx Network Medium","source_url":"https://medium.com/bzxnetwork/b0x-rebrands-to-bzx-and-announces-mainnet-launch-date-ed4e0c4dd2df"},{"date":"2018-12","event":"bZx raises approximately $7.8 million in a BZRX token ICO.","source":"Decrypt","source_url":"https://decrypt.co/resources/bzx-ethereum-defi-decentralized-finance-explained-guide"},{"date":"2019-06","event":"Fulcrum DeFi margin trading interface launches on Ethereum mainnet.","source":"IQ.wiki / Ivan on Tech Academy","source_url":"https://iq.wiki/wiki/bzx"},{"date":"2019-07","event":"bZx Protocol mainnet launch following rebrand from 'b0x'.","source":"bZx Network Medium","source_url":"https://medium.com/bzxnetwork/b0x-rebrands-to-bzx-and-announces-mainnet-launch-date-ed4e0c4dd2df"},{"date":"2019-10","event":"Torque fixed-interest lending front end launches.","source":"IQ.wiki","source_url":"https://iq.wiki/wiki/bzx"},{"date":"2020-02-15","event":"First flash loan attack on Fulcrum: attacker exploits undercollateralization logic bug, netting approximately $350,000 in ETH.","source":"CoinDesk","source_url":"https://www.coindesk.com/tech/2020/02/19/everything-you-ever-wanted-to-know-about-the-defi-flash-loan-attack"},{"date":"2020-02-18","event":"Second flash loan attack: attacker manipulates sUSD price oracle on Kyber Network and extracts approximately $633,000 in ETH.","source":"CoinDesk","source_url":"https://www.coindesk.com/markets/2020/02/18/defi-project-bzx-exploited-for-second-time-in-a-week-loses-630k-in-ether"},{"date":"2020-07","event":"BZRX governance token launched via Uniswap IDO.","source":"IQ.wiki / Decrypt","source_url":"https://iq.wiki/wiki/bzx"},{"date":"2020-09-14","event":"Third exploit: iToken duplication bug allows attacker to mint ~$8.1 million in tokens including LINK, ETH, USDT, USDC, and DAI.","source":"Finance Magnates / bZx Incident Report","source_url":"https://www.financemagnates.com/cryptocurrency/news/defi-protocol-bzx-lost-8-1-million-in-a-third-attack/"},{"date":"2021-08-23","event":"bZeroX, LLC transfers protocol control to bZx DAO; founders describe move as making the protocol 'enforcement-proof'.","source":"CFTC Press Release 8590-22","source_url":"https://www.cftc.gov/PressRoom/PressReleases/8590-22"},{"date":"2021-11-05","event":"Fourth and largest breach: phishing email compromises developer private keys; over $55 million drained from Polygon and BSC deployments and affected user wallets.","source":"CoinDesk / The Record","source_url":"https://www.coindesk.com/business/2021/11/05/defi-lender-bzx-suffers-hack-for-reported-55m"},{"date":"2021-11-12","event":"Kaspersky attributes November 2021 hack to BlueNoroff, a North Korean state-linked threat actor.","source":"Halborn Security blog","source_url":"https://www.halborn.com/blog/post/explained-the-bzx-hack-november-2021"},{"date":"2022-05-02","event":"Class action Sarcuni et al. v. bZx DAO filed in S.D.
