Vitalik proposes gas cap to enhance Ethereum security
2025/07/07 08:40Ethereum co-founder Vitalik Buterin and researcher Toni Wahrstätter have introduced EIP-7983, a new proposal to cap gas usage per transaction at 16.77 million units.
The cap is designed to improve Ethereum’s network security, performance consistency, and compatibility with zero-knowledge virtual machines (zkVMs).
The proposed limit equals 2²⁴ gas units, or 16.77 million, and would apply to individual transactions—not the overall block gas limit.
Under current rules, a single transaction can consume an entire block’s gas, creating a vector for denial-of-service (DoS) attacks and network instability.
EIP-7983 aims to prevent such attacks by forcing large transactions to be split into smaller, manageable segments.
This change is expected to make gas distribution across the network more predictable and reduce the chance of network congestion.
Transactions attempting to exceed the 16.77 million gas limit would be rejected during block validation.
The change is purely protocol-level and doesn’t impact the adjustable block gas limit that miners and validators control.
Buterin and Wahrstätter argue that the proposed limit balances performance and complexity.
According to the proposal, it allows for sophisticated DeFi interactions and contract deployments without introducing excessive risk.
While not backward-compatible for transactions above the cap, the authors noted that most current transactions are already well below this threshold.
Therefore, the proposal is expected to have minimal impact on user experience and developer operations.
EIP-7983 builds upon previous work like EIP-7825, which also sought to enhance execution predictability on Ethereum.
The proposal aligns with Buterin’s broader vision of simplifying Ethereum’s base protocol.
In May, he advocated for reducing Ethereum’s complexity across consensus, execution, and shared layers.
He argued that Ethereum’s increasing intricacy has resulted in slower development, higher maintenance costs, and elevated security risks.
Buterin has also recently proposed a novel “pluralistic identity” system designed to enable privacy-preserving, equitable participation in digital environments.
The proposed gas cap reflects ongoing efforts to streamline Ethereum’s infrastructure while maintaining the flexibility needed to support evolving use cases.
If adopted, EIP-7983 could enhance Ethereum’s resilience and scalability in the long term.
At the time of reporting, Ethereum price was $2,594.66

AI investment enters the "Trough of Disillusionment", the next 18 months will be a life-or-death test!
Goldman Sachs believes that the AI investment cycle is currently in the "trough of disillusionment," but this is not the first time. The core contradiction lies in the fact that the business models of new cloud computing providers are highly dependent on end-user returns from AI spending, while currently "there are basically zero companies that can attribute profits to AI." Social Capital founder Palihapitiya has clearly defined an 18-month key window, during which the market will decide which AI business models are sustainable and which are not.
Anthropic's Core Concern: Revenue Can Be Withdrawn at Any Time, but Computing Power Costs Are Locked in for up to 20 Years
Zheshang Securities believes that Anthropic's revenue is mainly based on usage-based billing, with remaining performance obligations covering only about 5.1 months of annualized revenue, while compute power costs are already locked in with $895.4 billion in irrevocable commitments, some extending as far as 2045. Revenues can be reduced at any time, but costs are non-exitable, creating a highly asymmetric maturity gap between the two—this is the company's real core constraint.
Triple Pressure from the Federal Reserve, Treasury, and Congress; Goldman Sachs: Liquidity Crisis May Occur in 2027
Goldman Sachs warns that the reserve ratio of bank assets has dropped to around 11%, only slightly above the crisis trough of 2019. In the second half of 2027, a deadlock in debt ceiling negotiations will force the Treasury to rebuild the TGA, triggering a "perfect storm" of a sharp drop in reserves and a surge in T-bill supply; combined with stalled money market fund buying, this will create a huge liquidity black hole. The Federal Reserve could be forced into the awkward position of lowering interest rates and launching large-scale bond purchases to rescue the market.
