Editor's Note: This article discusses the Blob space scarcity issue faced by Ethereum Layer 2 (L2). As the L2 chain grows, multiple L2s compete for limited Blob storage, leading to skyrocketing fees and increased user costs. Even with the Pectra upgrade increasing the Blob count to 6, the problem can only be temporarily alleviated but not fundamentally resolved. Solutions include short-term Pectra upgrades, mid-term PeerDAS implementation, and long-term DA scaling. However, it is still uncertain whether these solutions can be implemented in a timely manner.

Below is the original article content (reorganized for better readability):

Ethereum L2 is about to face a bottleneck. Currently, 55% of all Blob space has been consumed by just two chains, and at the current growth rate, we are only a few months away from a complete collapse.

The following is what is happening

Blob Space Exhausted, Is Ethereum L2 Also on the Brink of Collapse?

First, let's understand what is collapsing: Blobs = L2's special storage Current limit = 3 Blobs per block Reality = dozens of L2s vying for these 3 spots. It's like a highway with only 3 lanes, and 50 evolving cities are fighting for these lanes.

Day-to-day data clearly shows a problem, Blob fee spikes:

• During transaction times

• During airdrops

• When new L2 launches operations

Each spike = higher user cost

Even the Pectra upgrade (increasing Blob count to 6) cannot save us. At the current growth rate, we will reach maximum capacity in May 2025. And that's assuming no change in growth. (Sidenote: Growth won't stay the same—it's accelerating).

The Real Challenge

Issue: L2 Competing for Limited Blob Space

Approach: Increased Demand → Base Fee Rise

Reason: Each Transaction Requires Blob Space

Any L2 optimization cannot solve this fundamental bottleneck.

Core developers know this is a key issue. Vitalik Buterin said increasing the Blob count from 3 to 6 is more important than all other Pectra upgrades combined. But doubling the capacity will only give us a few more months, not years.

Solutions Under Research

Short Term: Double Blob Space (Pectra)

Mid Term: PeerDAS Implementation

Long Term: Advanced DA Expansion

But will they arrive before we hit the bottleneck? This issue is affecting everyone:

• DEX transaction costs are rising

• Perpetual protocols face skyrocketing base fees

• Users are paying more for basic transaction fees

At PolynomialFi, our base fees have increased by 300% in recent months.

A Glimmer of Hope?

This crisis has emerged because people are truly starting to use Ethereum L2. But if we don't address it soon, users may look elsewhere.

Summary

• Blob space is nearing its limit

• Next crisis expected within 6 months

• Urgent need for scaling solutions

• Every L2 user is impacted

If you want Ethereum to scale, this is the battle to watch.

Mixin has launched USTD-margined perpetual contracts, bringing derivative trading into the chat scene.

The privacy-focused crypto wallet Mixin announced today the launch of its U-based perpetual contract (a derivative priced in USDT). Unlike traditional exchanges, Mixin has taken a new approach by "liberating" derivative trading from isolated matching engines and embedding it into the instant messaging environment.

Users can directly open positions within the app with leverage of up to 200x, while sharing positions, discussing strategies, and copy trading within private communities. Trading, social interaction, and asset management are integrated into the same interface.

Simplified Trading Experience: No KYC Required, Opening a Position in Five Steps

Based on its non-custodial architecture, Mixin has eliminated friction from the traditional onboarding process, allowing users to participate in perpetual contract trading without identity verification.

The trading process has been streamlined into five steps:

· Choose the trading asset

· Select long or short

· Input position size and leverage

· Confirm order details

· Confirm and open the position

The interface provides real-time visualization of price, position, and profit and loss (PnL), allowing users to complete trades without switching between multiple modules.

Social-Native Trading: Strategy and Execution Completed in the Same Context

Mixin has directly integrated social features into the derivative trading environment. Users can create private trading communities and interact around real-time positions:

· End-to-end encrypted private groups supporting up to 1024 members

· End-to-end encrypted voice communication

· One-click position sharing

· One-click trade copying

On the execution side, Mixin aggregates liquidity from multiple sources and accesses decentralized protocol and external market liquidity through a unified trading interface.

By combining social interaction with trade execution, Mixin enables users to collaborate, share, and execute trading strategies instantly within the same environment.

Referral Mechanism: Non-institutional users can receive up to 60% fee split

Mixin has also introduced a referral incentive system based on trading behavior:

· Users can join with an invite code

· Up to 60% of trading fees as referral rewards

· Incentive mechanism designed for long-term, sustainable earnings

This model aims to drive user-driven network expansion and organic growth.

Self-Custody Architecture and Built-in Privacy Mechanism

Mixin's derivative transactions are built on top of its existing self-custody wallet infrastructure, with core features including:

· Separation of transaction account and asset storage

· User full control over assets

· Platform does not custody user funds

· Built-in privacy mechanisms to reduce data exposure

The system aims to strike a balance between transaction efficiency, asset security, and privacy protection.

A New Path for On-Chain Derivatives

Against the background of perpetual contracts becoming a mainstream trading tool, Mixin is exploring a different development direction by lowering barriers, enhancing social and privacy attributes.

The platform does not only view transactions as execution actions but positions them as a networked activity: transactions have social attributes, strategies can be shared, and relationships between individuals also become part of the financial system.

Regulatory Background

Mixin's design is based on a user-initiated, user-controlled model. The platform neither custodies assets nor executes transactions on behalf of users.

This model aligns with a statement issued by the U.S. Securities and Exchange Commission (SEC) on April 13, 2026, titled "Staff Statement on Whether Partial User Interface Used in Preparing Cryptocurrency Securities Transactions May Require Broker-Dealer Registration."

The statement indicates that, under the premise where transactions are entirely initiated and controlled by users, non-custodial service providers that offer neutral interfaces may not need to register as broker-dealers or exchanges.

About Mixin

Mixin is a decentralized, self-custodial privacy wallet designed to provide secure and efficient digital asset management services.

Its core capabilities include:

· Aggregation: integrating multi-chain assets and routing between different transaction paths to simplify user operations

· High liquidity access: connecting to various liquidity sources, including decentralized protocols and external markets

· Decentralization: achieving full user control over assets without relying on custodial intermediaries

· Privacy protection: safeguarding assets and data through MPC, CryptoNote, and end-to-end encrypted communication

Mixin has been in operation for over 8 years, supporting over 40 blockchains and more than 10,000 assets, with a global user base exceeding 10 million and an on-chain self-custodied asset scale of over $1 billion.
