PANews 7月2日消息，跨链互操作协议 Poly Network 疑似再度被黑客攻击，据吴说统计，黑客通过 Poly Network在数条链上增发资产，影响资产多达数十种。 在 Metis 上增发了 99,999,184 BNB 和 100 亿 BUSD； 在 Heco 上增发了 999.8127T SHIB、87,579,118 COW 和 999,998,434 OOE； 在 Polygon 上增发了 636,643,868 STACK、88,640,563 GM 和 2,175,053 03； 在 Ethereum 上增发了 378,028371 STACK、82,854,568 XTM和11,026,341 SPAY； 在 Avalanche 上增发了 89,383,712 GM； 在 BSC 上增发了 8,882,911 METIS、926,160,132 DOV、978,102,855 SLD 等资产。 目前该名黑客已通过部分增发资产出售获利。需要注意的是，Poly Network 流动性不足，不少巨额资产如BNB 与 BUSD 应无法跨链流出。2021年 PolyNetwork遭黑客盗币超过 6 亿美金，成为 DeFi 历史上最大的盗币案，随后在与黑客沟通后返还资产。 相关专题：史上最大的加密资产攻击事件

Crypto Options Narrative [6/6] The current trend in the options TVL (Total Value Locked) is focused on selling options rather than buying them, which leads to a structural liquidity mismatch. This is expected to change as more alternatives for generating yield through options become available and the market becomes more professionalized, leading to increased competition for yield and lower returns. A balance between buying and selling options will improve price discovery and impact the business models of some DOVs (Decentralized Option Venues). There is currently no clear winning solution for DeFi options, with all existing mechanisms carrying some form of inefficiencies. The DeFi options space is expected to grow in the coming years, with the potential for on-chain options to reach 60 times their current usage. This growth will be facilitated by improved technology, deeper liquidity, and institutional trader adoption. However, as the complexity of the space increases with the introduction of more exotic options, it is important to remember that risk is merely being transferred, not vanished. Thank you for reading.

Crypto Options Narrative [3/6] The current DeFi options technology has many issues that are preventing it from growing. CLOBs (Centralized Order Book) has struggled the most due to its on-chain performance limitations compared to centralized exchanges (CEXs). DOVs (Decentralized Options Vaults) are not popular due to their limited upside and unlimited downside. Additionally, DOVs create misaligned incentives between market makers and vault depositors, which leads to underpriced options. AMM (Automated Market Maker) LPs (liquidity providers) are also exposed to toxic flows and unhedged positions, which leaves them vulnerable to arbitrage. AMMs also offer limited strike prices and expiry dates, making it difficult for traders to use options as a risk management tool. Furthermore, the lack of a secondary market for offloading inventory and the absence of viable option pricing functions in smart contracts make price discovery inefficient.

Crypto Options Narrative [2/6] The current state of DeFi options can be broken down into four categories: automated market makers (AMMs), central limit order books (CLOBs), infrastructure, and structured option products. CLOBs offer a similar options trading experience as centralized exchanges but are limited by the current technology's latency and throughput. Option AMMs rely on liquidity providers depositing capital into pools that price options using a modified Black-Scholes formula. Option infrastructure provides solutions for minting and settling contracts, making it easier for other option projects to develop on top of it. Structured option products include DeFi options vaults (DOVs) and yield products. DOVs offer a user-friendly format for the option writing process but are limited for more advanced traders. Yield products carry out more complex strategies using a variety of options and derivatives, with protective measures for investors' capital.
