      "detailed_summary_zh": "Binance 宣布，在 BounceBit 项目因遭遇黑客攻击而决定永久关停 BounceBit Chain 后，将终止对 BounceBit（BB）的主网支持。BB 的充值和提现将迁移至 BNB Smart Chain（BEP20）网络。\n\n这一事件意义重大，因为它标志着一条 Layer 1 区块链在遭受安全漏洞后被永久关停，迫使 BB 持有者迁移至 BNB Smart Chain。同时，这也说明交易所变更支持网络会直接影响中等市值代币的生存能力和网络选择。\n\n据报道，此次攻击造成了约 300 万美元的损失，BounceBit 因此决定永久关停原链。在币安上，BB 的充值和提现将采用 BNB Smart Chain 的 BEP20 代币标准，用户需选择新网络以避免资产损失。",
      "detailed_summary_en": "Binance announced it will discontinue mainnet support for BounceBit (BB) after the project decided to permanently sunset BounceBit Chain following a hacking incident. Deposits and withdrawals of BB will be moved to the BNB Smart Chain (BEP20) network.\n\nThis is significant because it marks the permanent shutdown of a Layer 1 blockchain after a security breach, forcing BB holders to migrate to BNB Smart Chain. It also highlights how exchange support changes can directly affect a token's viability and network choice for a mid-cap asset.\n\nThe exploit reportedly resulted in a loss of about $3 million, leading BounceBit to permanently sunset its chain. On Binance, BB deposits and withdrawals will now use the BEP20 token standard on BNB Smart Chain, so users must select the new network to avoid asset loss.",
