$1.2 billion worth of Bitcoin (BTC) options are set to expire, while Ethereum (ETH) put positions have remained at high levels for a consecutive month.

Crypto analytics platform Greeks.live reported that on July 17, 19,000 BTC options expired, with a Put-Call Ratio (PCR) of 0.9, a max pain point of $63,000, and a nominal value of around $1.2 billion. Meanwhile, 123,000 ETH options expired, with a PCR of 1.61, a max pain point of $1,800, and a nominal value of roughly $230 million. In terms of market performance, BTC has continued to fluctuate above $60,000 this week, having traded in the $60,000 to $65,000 range for over a month. Sharp swings in U.S. equities (SpaceX and storage sectors) have not yet had a noticeable impact on the crypto market. Looking at options positions, around 5% of options expired this week, leading to a slight drop in overall open interest, mainly due to low market volatility and reduced trading opportunities. BTC’s Gamma Exposure (GEX) is mainly concentrated around $64,000 and $70,000. ETH’s GEX is primarily in the $1,825 to $2,000 range, with a relatively dispersed distribution. Some traders have started positioning for a rebound via slightly out-of-the-money options. The proportion of large bullish trades has continued to rise recently, dominated by short-term bull spread buying strategies. Notably, ETH’s Put-Call Ratio has stayed above 1 for a consecutive month, hitting 1.61 this week. The high proportion of put options outstanding reflects clear market divergence on ETH’s future outlook, with intensified bull-bear rivalry.

Ethereum Foundation leverages AI to mine vulnerabilities: Successfully identifies security flaws, notes that manual review remains irreplaceable.

The Ethereum Foundation has disclosed that its Protocol Security team is using AI agents to conduct vulnerability hunting of Ethereum client software to boost network security. During testing, the AI successfully identified a vulnerability in the Gossipsub message propagation protocol that allows remote attackers to trigger node crashes, leading to validator nodes going offline. The flaw has since been patched and assigned CVE ID CVE-2026-34219. However, the foundation notes that AI’s biggest challenge is not discovering vulnerabilities, but distinguishing actual flaws from false positives. AI can generate vulnerability descriptions, impact analyses, and exploit code, but may also produce seemingly plausible yet non-existent issues—requiring security researchers to conduct thorough verification. The foundation outlined three common types of false positives: crashes occurring only in test environments, exploit paths that cannot be leveraged in real-world scenarios, and invalid proofs in formal verification. Additionally, the Ethereum Foundation believes AI is currently better at analyzing individual code issues, but has limited ability to identify complex attack chains formed by multiple legitimate operations—an attack vector that has been the primary cause of breaches for multiple crypto protocols this year. Going forward, the foundation plans to have AI assist in generating potential attack paths, which will then be verified via manual and automated testing to further improve the efficiency and accuracy of vulnerability discovery.

Vitalik proposes the "Minimalist Consensus Chain" plan: Reconstructing Ethereum's consensus layer using ZK-STARK, with the goal of supporting one million validators.

Ethereum co-founder Vitalik Buterin has released a new research paper titled "The Extremely Lean Chain," proposing a drastically streamlined design for Ethereum’s consensus layer. The plan leverages "Lean" upgrades including single-slot finality, recursive STARK proofs, and quantum-resistant signature aggregation to significantly reduce consensus chain state storage requirements, shifting most state management and zero-knowledge (ZK) proof responsibilities to validators. Vitalik argues that this proposal would eliminate the Beacon Chain’s current complex periodic state processing workflows, drastically cut system overhead, enable Ethereum to scale to millions of validators in the future, and also improve validator anonymity. Per the design, validators no longer need to store large amounts of data such as public keys, withdrawal credentials, activation and exit records on-chain long-term; instead, they only retain minimal core state like effective balances and public key indexes, while the rest of the data is submitted and verified periodically via STARK proofs. The proposal also introduces mechanisms like daily balance update proofs, ZK-STARK privacy protection, and daily re-randomization of validator identities, which enhance network scalability while further boosting privacy and censorship resistance. Vitalik noted that with an approximately one-day proof period, the scheme can complete proof generation on regular hardware, reduce on-chain burden through proof aggregation, and provide a new technical roadmap for the long-term expansion of Ethereum’s consensus layer.

EthLabs released its Week 2 update report, focusing on advancing Ethereum interoperability, PropAMMs, and financing progress.

EthLabs founder Barnabé Monnot (barnabé.eth) has published his "Week 2" update, recapping the team’s latest progress in the launch and funding phases, as well as key ecosystem discussion priorities. On interoperability, the team said it is growing more confident in "zero-knowledge (zk)-based asynchronous interoperability", which it believes will help build more secure cross-chain bridges and improve the native distribution of assets across Ethereum’s multi-layered networks. Current cross-chain paths still face latency issues, particularly for L2→L1 transfers; against this backdrop, the intents mechanism can act as a transitional solution, while L1’s ample liquidity supports matching with cross-chain solvers. Additionally, L1→L2 paths are expected to drastically cut confirmation latency via the Fast Confirmation Rule (FCR), with clients already beginning to integrate the mechanism. In ecosystem discussions, PropAMMs (proposal-based automated market makers) have emerged as a recent focus for multiple teams and researchers, centered on their potential to optimize the balance between L1 execution efficiency and block building. Meanwhile, ENS is highlighted as "critical Ethereum infrastructure", with the team continuing to engage relevant stakeholders to advance its development. For team expansion, EthLabs has received over 300 applications to date, having processed roughly 20% of them. The team aims to grow to around 10 members in the short term, and roughly 20 in the medium term, prioritizing talent with engineering capabilities and domain expertise. On the funding front, EthLabs noted its current financing round is nearing completion, having secured early backing from investors including BitMNR, Sharplink, and Ethereum Joseph. It plans to add 1–2 core investors before moving to the next phase.

Vitalik: Ethereum to enter 'Lean Ethereum' phase, core protocol may undergo full overhaul in the next 3–4 years

Ethereum co-founder Vitalik Buterin published a post stating that Ethereum researchers recently held a meeting in Berlin, continuing discussions with client teams initiated in Svalbard in April, to update the blockchain’s long-term protocol roadmap. Vitalik noted that "Lean Ethereum" is not a single upgrade, but a series of protocol evolutions to be rolled out gradually over the next 3 to 4 years—its impact is comparable to The Merge as Ethereum’s second major iteration, while the current phase may mark its third major evolution. He outlined core upcoming changes for Ethereum: replacing direct execution verification with recursive STARK proofs, integrating post-quantum cryptography, adjusting the consensus mechanism to a decoupled design of available chain and finality, and implementing multi-dimensional gas models alongside state structure restructuring. At the state level, Ethereum may form a "two-tier state structure" around 2030, consisting of ~2TB of traditional dynamic state and ~100TB of new scalable state to support scaling needs across different application scenarios. Vitalik emphasized that privacy capabilities will no longer be an add-on feature, but a core goal of protocol design. The system will also rely more on formal verification to boost security, and push the EVM toward higher-level abstractions, with the underlying layer potentially transitioning gradually to RISC-V or leanISA architectures. Key parameters including gas limits, blob sizes, and block times will be adjusted multiple times over the next few years, as Ethereum continues scaling via client optimizations and protocol upgrades. Vitalik concluded that Ethereum is entering a phase of continuous restructuring and scaling, aiming to complete underlying system upgrades without disrupting the existing application ecosystem.
