案例 4: @PleasrDAO:2023 年 7 月 19 日,他们开始针对 PleasrDAO 核心团队成员 Jamis,他不久前遭受了脑外伤。遗憾的是,这导致了 130 万美元的损失。其中一名较大的受害者损失了价值 807,000 美元的 MAGIC。而 Yahya 获得 14.4 万美元。点击链接查看详情。

诈骗


Yahya 花费了数千美元购买手表和未发行的 Juice WRLD 歌曲,例如:Dark Tints、Biscotti in the Air、Oxy in the Dark、No Jumper。

诈骗


当他面对人们时,他对自己的行为几乎没有表现出悔意:「我不是一个坏人,我就像兄弟一样,他们只是为查找提供了很多钱给我」。

诈骗


在参与非法活动之前,Yahya 是 SMM 的 Benzinga 贡献者,使用名称 Yahya M**。我不理解如果一切都能联系起来,您为什么要冒这个风险来查找 SIM 卡交换。

诈骗


我希望其中的一些内容可以帮助作为打击这些诈骗者的行动基础,这些诈骗者通过 SIM 交换和网络钓鱼伤害了该领域的许多人。聊天记录等东西都已存档,我十分愿意提供给受害者。

Single-Day Plunge of 30%, Arthur Hayes Suddenly Liquidates: Why Did ZEC Get Exploded by Security Issues?

On June 5th, Zcash founder Zooko Wilcox disclosed a critical soundness vulnerability in the project's latest Orchard privacy pool. This flaw, found in the elliptic curve multiplication constraints, could allow an attacker to create unlimited counterfeit ZEC within the shielded pool, with transactions appearing valid. The vulnerability was discovered in late May by security researcher Taylor Hornby, who utilized Anthropic's new Opus 4.8 AI model for a targeted audit. The Zcash ecosystem had already performed an emergency network upgrade to patch the issue. However, the detailed disclosure triggered severe market panic, causing ZEC's price to plummet over 30% in a single day. Notably, prominent investor Arthur Hayes announced he had sold his entire ZEC position following the news. The incident starkly challenges the "technological trust" narrative central to privacy coins. Despite years of top-tier cryptographic audits, the bug persisted until uncovered with advanced AI-assisted research. This highlights the growing gap between theoretical perfection and practical implementation in privacy technology. The event serves as a industry-wide warning: in an AI-driven security landscape, the assumption that "undiscovered equals safe" is obsolete. It underscores the urgent need for continuous, proactive security practices combining AI audits, formal verification, and rapid response mechanisms.

Breaking the Curse of DeFi Cascading Liquidations, Vitalik Proposes a New Solution

**Vitalik Buterin Proposes New DeFi Design to Eliminate Forced Liquidations** Ethereum co-founder Vitalik Buterin has published a proposal for a new decentralized finance (DeFi) architecture aimed at removing the automatic liquidation mechanisms prevalent in current lending protocols. The core idea involves creating synthetic assets using options as building blocks, fundamentally avoiding the抵押借贷结构 that triggers forced sell-offs. The proposal responds to a recurring flaw in DeFi: during sharp market downturns, mass自动清算 of under-collateralized positions can exacerbate price declines, creating systemic selling pressure and market instability, as evidenced by recent crypto market volatility. Buterin's model would split an asset like 1 ETH into two option-like derivatives, P and N, pegged to a price index with a set strike price and expiration. At expiry, an oracle determines the settlement price to allocate the underlying ETH between P and N holders. This design eliminates the "cliff" of instant liquidation. Instead, a position's value would gradually drift from its target peg if not actively rebalanced by the user, transferring the rebalancing decision from the protocol to the user or automated tools. A key advantage is the reduced reliance on high-frequency, real-time oracle price feeds, which are vulnerable to manipulation and errors in current systems. The delayed settlement in the options model allows for more robust, fault-tolerant oracle designs. However, significant challenges remain for practical adoption. High transaction costs (slippage) from frequent rebalancing on automated market makers (AMMs) could erode user funds. The model may not be suitable for stablecoins requiring a strict 1:1 dollar peg, as it inherently allows for value drift. Success would depend on developing new liquidity provisioning models and deep markets for these synthetic assets. The proposal represents a fundamental rethinking of DeFi risk management, challenging the industry to explore alternatives to被动集中平仓 rather than merely optimizing existing liquidation processes. It remains a theoretical framework awaiting implementation and testing by development teams.

Bitcoin's Decline Marks the Transformation of Crypto

Title: The Decline of Bitcoin Marks the Transformation of Crypto While Bitcoin's price recently fell below $70,000, down approximately 45% from its peak, the broader crypto industry is not following it into decline. Instead, crypto is maturing and evolving beyond its dependence on Bitcoin's price movements. Two of Bitcoin's core functions are being usurped. First, AI has captured its role as the primary speculative asset. AI, with its tangible revenue, explosive demand, and massive capital inflows ($700-830 billion in 2024), is siphoning off the speculative "hot money" that once drove Bitcoin. It also contributes to a sustained high-interest-rate environment, further tightening liquidity for assets like Bitcoin. Second, dollar-pegged stablecoins like USDC and USDT have replaced Bitcoin as the crypto market's foundational currency and primary on/off-ramp. Most trading pairs and on-chain transactions are now settled in stablecoins, severing the historical link where all capital inflows had to pass through Bitcoin first. This decoupling allows projects to thrive based on their own fundamentals rather than Bitcoin's price. Examples include Hyperliquid, an on-chain derivatives exchange with annual revenues of $8-13 billion, and prediction market platform Polymarket, valued at $200 billion with $3.65 billion in annual fees. These projects are evaluated on traditional metrics like revenue and user growth. New opportunities are emerging, particularly around privacy. Privacy coins like Zcash (ZEC) are seeing surging demand, while infrastructure like NEAR enables private, cross-chain asset transfers without requiring users to hold a specific token—privacy becomes a universal service layer. In this new paradigm, stablecoins are the universal cash, various project tokens represent equity, and privacy-enabled cross-chain coordination layers (like NEAR) act as the critical infrastructure connecting a fragmented, multi-chain ecosystem. Bitcoin is now just one asset among many. The era where the entire crypto market moved in lockstep with Bitcoin is over. The industry's health should now be judged by project fundamentals—real revenue, active users, and tokenomics that capture value—and the development of the underlying infrastructure enabling a mature, dollar-denominated crypto economy.

Lightspark CEO: In Ten Years, Bitcoin Will Be as Invisible as TCP/IP, Yet Power Trillions in Daily Transactions

A decade from now, Bitcoin will function like TCP/IP — invisible yet foundational, supporting trillions in daily transactions globally, according to Lightspark CEO David Marcus. In this future, a coffee shop in Lagos receives instant payment, a manufacturer in São Paulo settles an invoice with a supplier in Ho Chi Minh City, and a freelancer in Bangalore gets paid weekly from an Austin startup — all via Bitcoin's settlement layer, with none of the parties consciously interacting with it. This vision parallels the adoption of open protocols: first driven by necessity where existing systems fail, then scaling rapidly as tools mature and economic benefits become clear. The structural shift begins with wallets. Modern non-custodial wallets, like Spark, allow users to hold dollars, local currency, and Bitcoin in a single address, seamlessly switching between them. This eliminates friction and revolutionizes global custody, moving significant deposits to user-controlled keys not by ideology, but by superior utility. As a result, Bitcoin becomes the default savings layer for billions, as its fixed supply and appreciating value make it a rational choice for savers holding it alongside stablecoins in their everyday wallets. Businesses follow a similar path, from small companies in emerging markets to multinational corporations, holding Bitcoin alongside operational stablecoins. The latest trend is direct Bitcoin transactions for commerce. When both parties hold Bitcoin, transacting in it becomes the simplest option — no conversions, no intermediary currency. This starts in niche areas like high-value B2B settlements but grows as infrastructure makes sending Bitcoin as easy as stablecoins. An accelerating force is AI agents. By 2036, AI agents conducting commerce on behalf of individuals and firms will increasingly choose Bitcoin for settlement. Optimizing for speed, finality, and minimal counterparty risk across jurisdictions, they find Bitcoin's global, neutral, and programmable network ideal for netting and settling obligations. Thus, Bitcoin is becoming the native currency for machine commerce, just as it has become a native savings asset for humans. The global monetary system is being rebuilt from the protocol layer: open infrastructure, default self-custody, Bitcoin settling everything underneath, with stablecoins as the interface. Most users won't think about Bitcoin when they transact — and they won't need to.
