Ethereum's Evolving Privacy Landscape: Addressing Gas Fee Burns and Private Payments

By: Eva Baxter

Ethereum's ecosystem is increasingly grappling with the complexities surrounding Maximum Extractable Value (MEV) and privacy. Recent reports highlight that more than 50% of gas fees on some Ethereum layer-2 networks are being consumed by MEV-related activities, with bots extracting millions in profits without proportionate gas payment. This situation underscores a scaling and market fairness issue that demands immediate attention.Reports from Alchemy reveal that during a 30-day period, over $24 million in MEV profit was extracted from the Ethereum network alone. The visibility of large transactions in the mempool often leads to substantial slippage due to front-running and sandwich attacks.

The Ethereum Foundation is responding to these challenges with a multifaceted approach focusing on privacy and scalability. Their initiatives include private writes, reads, and provings to reduce the visibility of transaction data. Companies like TEN Protocol are exploring how Trusted Execution Environments (TEEs) can encrypt execution environments to maintain privacy and prevent data leaks. TEN Protocol emphasizes the importance of read-side privacy due to its impact on strategic leaks that fuel MEV exploits. Manai from TEN stresses that encrypting balances, positions, and other critical data can make decentralized finance (DeFi) more viable for institutional players.

Meanwhile, StarkWare's integration of EY's Nightfall protocol on its Starknet network is a significant advancement for institutional privacy requirements on public Ethereum rails. Nightfall enables private transactions without sacrificing auditability, making it attractive for banks and corporations. This zero-knowledge (ZK) privacy layer allows institutions to perform private payments, treasury management, and tokenized asset transfers securely, adhering to transparency and regulation while ensuring confidentiality. This development is poised to reshape how enterprises engage with blockchain technology by facilitating private DeFi activities on open networks, further stressing the need for adaptable privacy solutions that align with regulatory standards. Such initiatives might lead to significant infrastructural changes in how privacy is integrated into the Ethereum network by 2026.
