Ethereum fork BPO2 is live, adjusting scalability and supporting the network's economic model.

• Ethereum fork BPO expands blob limit
• L2s gain more space for on-chain data
• Ethereum's economic model remains balanced.

As L1 networks evolve, the pressure for decentralization steadily increases. This movement helps explain why scalability has become a central priority for developers, especially in networks competing for user and application volume without compromising security.

In the case of Ethereum, this strategy involves strengthening second-layer networks, or L2s. Protocols like Arbitrum allow developers to create decentralized applications at lower costs, avoiding the high fees of the main layer. Within this context, the Ethereum fork BPO emerges as a relevant step in the network's architecture.

According to the official announcement, the fork raised the blob limit from 15 to 21 per block. In practice, this provides more space for L2s to publish data in each block, increasing processing capacity. The direct effect is improved scalability and a structural reduction in costs for users operating at these layers.

This adjustment goes beyond a simple technical gain. L2s play a direct role in Ethereum's economic model, since part of the fees paid for settlement returns to the mainnet. With greater use of L2s, the flow of value to the mainnet tends to grow, maintaining incentives for validators and developers.

BPO2 is live on Ethereum. 🥳

What does this mean? Ethereum continues to grow. We can now reach 14 blobs per Ethereum block—that's 2,3 times more than a month ago (when the target was 6 blobs) and 4,6 times more than seven months ago. There's plenty of room available for rollups to scale.

What does this mean? Ethereum keeps growing.

-> this is 2.3x more than 1 month ago (back then we targeted 6 blobs) and 4.6x more than 7 months ago.

Although some recent updates have had a negative short-term impact on revenue, the broader picture shows resilience. Consecutive updates have reduced fees and pressured revenue, with an estimated drop of around $100 million, while L2 earnings have declined sharply. Even so, Ethereum has maintained its pace of updates.

The main reason lies in the level of network activity. On-chain data indicates that the TVL of L1 applications has surpassed the US$300 billion mark, signaling continued growth in usage and adoption. This growth helps offset temporary revenue losses and sustains the ecosystem's interest.

Within this context, the Ethereum fork BPO gains strategic importance. With the network already showing consistent usage, increasing the blob limit creates space for more data per block, enabling a higher volume of transactions on the L2s.

The result is a positive feedback loop. More processed data increases economic activity, which encourages developers and keeps Ethereum's fundamentals in the spotlight in 2025.
