A recent academic study warns that Ethereum’s scaling solutions, known as Ethereum Layer-2 rollups, are incorrectly pricing small transactions. The research, conducted by experts from zkSecurity, Prooflab, and Imperial College London, indicates that current fee models distort the actual cost, directly affecting users with lower-volume operations. This situation not only leads to overcharging but also opens new security vulnerabilities.

The report’s main finding details that a major issue is that current fee structures are overly simplistic. These models group various costs—such as execution, data availability, and cryptographic proofs—into a single formula or apply fixed rules. As a result, small transactions end up being overpriced, forcing users to pay more than they should. Conversely, other operations may be underpriced, creating an imbalance that can be exploited.

This pricing problem arises in a context where Ethereum Layer-2 rollups are fundamental to the network’s scalability. Their goal is to process transactions off the main chain to reduce costs and increase speed. However, the research shows that the method for recording this data on the mainnet does not adequately distinguish between transactions, applying fixed costs that harm smaller operations and benefit larger ones.

The implications of this flaw are twofold. For the market, it means that ordinary users making modest transfers or interacting with low-value decentralized applications are unknowingly subsidizing higher-volume operations. Furthermore, from a security standpoint, it creates an attack vector, as malicious actors could flood the network with spam at an artificially low cost. This type of denial-of-service (DoS) attack would degrade network performance and increase costs for everyone.

Towards a Fairer Fee Model on Layer 2

The study underscores the urgent need to redesign the fee models in Ethereum Layer-2 rollups to more accurately reflect the true cost of each transaction. Although these solutions are vital for Ethereum’s future, their sustainability depends on implementing more sophisticated and equitable mechanisms. The next step for developers will be to create dynamic fee structures that protect small users and strengthen the overall security of the ecosystem, ensuring that scalability is not achieved at the expense of fairness and network robustness.

Oracle experienced a stock surge following announcements and strategic partnerships related to artificial intelligence in 2025. The integrations with NVIDIA and AMD, along with Oracle Database 23ai and AI tools in OCI, boosted the company’s valuation and, at times, temporarily elevated Larry Ellison’s net worth above Elon Musk in real-time rankings.

Announcements and Timeline in 2025

In March and June 2025, Oracle formalized collaborations and product enhancements focused on AI initiatives. The announcements and hardware-software integrations triggered a positive investor response, reflected in the rise of ORCL shares and upward analyst revisions.

Products and Technological Integrations

Oracle incorporated AI capabilities into its database and cloud infrastructure, facilitating enterprise use of AI models and vector searches. The products and services aim to simplify AI workflow implementation and improve efficiency in enterprise environments.

NVIDIA Integration

In March 2025, a joint statement with NVIDIA highlighted the integration of NVIDIA AI Enterprise software, accelerating inference and vector search operations in Oracle Database, combining NVIDIA’s software power with the advanced capabilities of Oracle’s database.

AMD Support and OCI Hardware

In June 2025, Oracle announced AMD support, integrating AMD Instinct MI355X GPUs into Oracle Cloud Infrastructure (OCI). This integration is designed to enhance AI workload performance through a combination of cloud hardware and optimized software.

Oracle Database 23ai and OCI AI Blueprints

Oracle Database 23ai and OCI AI Blueprints are proprietary products that simplify AI workflow and search implementations, forming part of a comprehensive strategy that combines database software, cloud tools, and external hardware support.

Market Impact and Larry Ellison’s Net Worth

The relationship between Oracle’s valuation and Larry Ellison’s net worth was evident when real-time indices showed his wealth temporarily surpassing Elon Musk. Media outlets such as Fortune, Bloomberg, and Forbes reported on how Ellison’s net worth was affected by movements linked to the ORCL stock surge.

Conclusion

The Oracle stock rally and its effect on Ellison’s net worth illustrate how the AI infrastructure race redistributes financial value and technological power. The episode raises practical implications for competition and centralization: in the short term, partnerships enable enterprise deployments and reduce operational costs, but in the medium term, they increase technology dependency risks, driving demand for open and decentralized alternatives to protect data sovereignty.

TL;DR

• World Chain activated Priority Blockspace for Humans, reserving block space for verified users during congestion without gas fee auctions.
• The feature is already live for 13 million verified users and was audited by Nethermind after public tests with Flashbots and Alchemy.
• Despite its expansion in the U.S., World has been suspended in Spain and Portugal over biometric data use in its digital identity network.

World Chain, the digital identity network tied to World — the project founded by Sam Altman — has activated a new feature on its mainnet called Priority Blockspace for Humans.

This tool automatically reserves part of each block for transactions from verified human users whenever the network faces congestion, eliminating gas fee auctions during those critical periods.

The goal is to guarantee that essential services like identity verifications, app access, and incentive claims remain operational and accessible without requiring users to pay elevated fees. The feature is already available for over 13 million people who completed biometric verification through the Orb device and aims to encourage developers to build applications within its ecosystem.

Priority Blockspace for Humans was tested on a public testnet with support from Flashbots and Alchemy and underwent independent audits by Nethermind. It was also integrated into World Chain’s Block Builder and Rollup Boost — a modular solution compatible with OP Stack that enables customized transaction ordering across various networks.

World Chain Seeks to Prioritize Humans Over Automated Bots

The company argues this approach prioritizes real human users over automated bots and maximizes efficiency during periods of high demand. According to Steven Smith, Vice President of Engineering at Tools for Humanity, the feature aims to make World Chain a more accessible and functional network for individuals while still taking advantage of the scalability and automation that artificial intelligence enables.

Since April, World Chain has expanded into six U.S. cities after previously avoiding the market due to restrictions around token distribution. However, its growth continues amid regulatory scrutiny. Authorities in countries like Spain and Portugal suspended World’s operations over privacy concerns tied to its biometric data practices — a controversy that remains unresolved.

The project maintains its target of surpassing one billion verified users and building blockchain infrastructure centered on digital identity, combining on-chain verification tools with custom solutions for prioritizing human transactions.
