EtherWorld has joined the Encrypt the Mempool Coalition, a growing Ethereum ecosystem initiative focused on bringing protocol-level mempool encryption to Ethereum. The coalition is pushing for encrypted transaction flow to become part of Ethereum’s upcoming upgrade roadmap, with the goal of reducing toxic MEV, front-running, sandwich attacks, and real-time censorship.

The Encrypt the Mempool Coalition believes the answer is yes. Its goal is to make Ethereum’s transaction pipeline more private, fair, and credibly neutral without forcing users into opaque private orderflow systems. This aligns closely with EtherWorld’s recent coverage of Ethereum’s encrypted mempool roadmap, including Ethereum Encrypted Mempool: Progress, Challenges & the Road to Hegota and Ethereum Coalition Pushes for Encrypted Mempool in Upcoming Hardfork.

Why EtherWorld Joined the Encrypt the Mempool Coalition

EtherWorld’s decision to join the Encrypt the Mempool Coalition reflects its long-standing commitment to Ethereum education, protocol research, and decentralization. The coalition brings together ecosystem participants who want Ethereum users to transact without exposing every pending transaction to searchers, bots, builders, and potential censors before block inclusion.

In its announcement, EtherWorld said it was proud to join the coalition and support the push to integrate an encrypted mempool EIP into Ethereum’s upcoming hard fork. The message focused on a clear goal: stopping toxic MEV and real-time censorship in a decentralized and credibly neutral way.

This is not only a technical issue. It is also about Ethereum’s values. Ethereum’s base layer is meant to be neutral infrastructure. However, when pending transactions are fully visible before inclusion, sophisticated actors can use that visibility to extract value from regular users. That creates an uneven playing field where users with less infrastructure protection are more exposed to front-running, sandwich attacks, and unfavorable execution.

EtherWorld has covered similar censorship-resistance discussions in the context of FOCIL and Hegota. Readers can also explore Hegota Should Complete the Holy Trinity of Censorship Resistance for a broader look at how encrypted mempools, threshold encryption, and inclusion guarantees may work together to strengthen Ethereum.

By joining the coalition, EtherWorld is supporting a roadmap where Ethereum does not rely only on wallets, RPC providers, or private relays to protect users. Instead, the coalition is advocating for protections that can be built closer to the protocol itself.

The Problem With Ethereum’s Public Mempool Today

Ethereum’s public mempool plays an important role in the network. It allows pending transactions to be broadcast openly before they are included in blocks. This supports decentralization because anyone can observe transaction flow and participate in the network.

When users submit transactions, their transaction details become visible before execution. Searchers and bots can inspect pending transactions and respond before those transactions are confirmed. This enables several harmful practices, including front-running, sandwich attacks, and real-time transaction censorship.

A sandwich attack is one of the most common examples. A bot sees a user’s swap in the mempool, places one transaction before it and another after it, and profits from the price movement created by the user’s own trade. The user receives a worse execution price, while the searcher extracts value from the visibility of the pending transaction.

This is one reason private orderflow has grown across Ethereum. Many users and applications now rely on private transaction routes to avoid being exposed in the public mempool. While this can help individual users, it also creates a new risk: transaction flow becomes fragmented across private channels. Instead of one open coordination layer, the ecosystem moves toward a system where access, routing, and protection depend on private infrastructure.

Ethereum needs a path where transactions can remain publicly accessible for inclusion while their sensitive contents remain hidden until ordering is finalized. Encrypted mempools aim to solve exactly this problem. They do not remove the mempool. They attempt to make it safer.

EtherWorld previously discussed this broader problem in Ethereum Introduces Clear Signing for Safer Crypto Transactions, where user protection was framed as a key part of Ethereum’s long-term usability. Encrypted mempools extend that protection from wallet signing to transaction propagation itself.

We're proud to join the new Encrypt the Mempool Coalition!

Alongside industry leaders, we're pushing to integrate an EIP to encrypt the mempool in Ethereum's I* Hardfork - to stop toxic MEV & real-time censorship in a decentralized & credibly neutral way.

How Encrypted Mempools Could Reduce MEV and Censorship

An encrypted mempool changes how transaction information is revealed. Instead of broadcasting transaction contents in plain text, users submit encrypted transactions. These transactions remain hidden until they are locked in for inclusion or until their ordering is fixed. Only after that point are they decrypted for execution.

This means searchers, builders, validators, or other observers cannot easily inspect the transaction in advance and exploit it. The key idea is to remove the visibility that enables toxic MEV while preserving the benefits of a shared transaction layer.

EIP-8105, titled Universal Enshrined Encrypted Mempool, proposes a protocol-level encrypted mempool design for Ethereum. The proposal aims to allow users to encrypt transactions until inclusion, helping protect against front-running and sandwich attacks while improving censorship-resistance guarantees. Importantly, the design is encryption-technology agnostic, meaning different decryption systems could potentially be used, including threshold encryption, MPC committees, trusted execution environments, delay encryption, or future cryptographic approaches.

Threshold encryption is one of the most discussed approaches. In this model, no single party can decrypt transactions alone. Instead, decryption requires cooperation from a threshold number of participants. This can reduce the risk of premature decryption and help maintain decentralization.

These are the kinds of questions being discussed in Ethereum research calls and public forums. The Ethereum PM repository has already hosted Encrypt the Mempool calls, including discussions around execution specs, consensus specs, test requirements, client implementation, and how encrypted mempool work may build on Glamsterdam and FOCIL.

For readers who want deeper context, EtherWorld’s Ethereum Coalition Pushes for Encrypted Mempool in Upcoming Hardfork explains how LUCID and related encrypted transaction flow proposals fit into this conversation.

Why This Matters for Hegota and Ethereum’s Roadmap

The Encrypt the Mempool Coalition is emerging at an important moment. Ethereum is already looking beyond Glamsterdam toward Hegota, where censorship resistance, transaction inclusion, and validator-side improvements are becoming major themes.

Hegota discussions have already included FOCIL, which focuses on enforcing transaction inclusion through fork-choice rules. FOCIL and encrypted mempools address different parts of the same broader challenge. FOCIL helps ensure transactions cannot be indefinitely excluded, while encrypted mempools help ensure pending transaction contents cannot be exploited or censored in real time before inclusion.

A future Ethereum block lifecycle could include stronger inclusion guarantees, less visible transaction content before ordering, and reduced dependence on private orderflow. That would be a major improvement for regular users, DeFi traders, institutions, wallets, and applications that want fair access to Ethereum without relying on centralized protection layers.

This is also why EtherWorld’s participation in the coalition matters. Ethereum upgrades are not only shaped by client teams and researchers. They are also shaped by public understanding, ecosystem alignment, and community pressure. Media and education platforms play an important role in explaining why these upgrades matter and what trade-offs they involve.

The Encrypt the Mempool Coalition is helping bring that issue into focus. By joining the coalition, EtherWorld is adding its voice to a broader push for Ethereum to remain open, neutral, and user-protective as the network evolves.

As Hegota discussions continue, encrypted mempools may become one of the most important areas to watch. If successful, they could help Ethereum reduce toxic MEV, improve transaction fairness, and preserve the public mempool as a decentralized coordination layer.
