Ethereum’un BPO Güncellemesiyle Veri Kapasitesi ve Ölçeklenebilirlik Yakın Takipte

This week, Ethereum took a step towards higher data capacity with the deployment of its second Blob Parameter-Only (BPO) main upgrade. The goal is to process data more efficiently using off-chain solutions before more comprehensive changes planned for 2026, and to increase scalability.

Highlights:

• The second BPO update supports higher rollup throughput without overloading the main chain by increasing the blob limits and targets.
• Developers see the higher blob target as a continuous indicator of network performance and node health.
• Scalability improvements are planned through subsequent steps such as gas limit increases and the 2026 Glamsterdam main wave.

The update went live on Wednesday at 01:01:11 UTC, with the blob limit per block increased from 15 to 21. Blobs are temporary data containers introduced to package transactions and enable lower-cost on-chain operations; thus, Layer-2 networks can produce more activity.

Why Is the Blob Target Important? In addition to a high closing rate, the update increased the blob target from 10 to 14. Developers generally consider the target more critical because it reflects the level Ethereum aims to maintain under normal conditions. Approaching the 21 blob limit for an extended period can put pressure on node bandwidth and storage; therefore, the target is a key indicator of network health.

Each blob can carry 128 kilobytes of data, meaning Ethereum can process approximately 2.6 megabytes of blob data per block. This additional capacity helps reduce direct congestion on the main chain by allowing rollups to bundle more transactions at once. Independent of scalability, blobs continue to play a role in balancing fees at the base layer. Since the first BPO update, the reduction in competition for block space has notably decreased transaction fee volatility.

Developers are continuing efforts to achieve more throughput for additional efficiency. During the mid-December All Core Developers meeting, discussions included raising the network’s gas limit from the current 60 million to 80 million with the activation of the second BPO. Such a step could enable more transactions and smart contract operations, further lowering fees during high-demand periods.

In later stages of 2026, the Glamsterdam main wave is planned, which is expected to further enhance scalability. This update includes potential to raise the gas limit to 200 million and features such as strengthening functionality between Block Access Lists and ZK-EVMs.

Buterin’s Commentary on Blockchain Trilemma Ethereum’s founder Vitalik Buterin claims that the network has now solved the blockchain trilemma problem. In a message posted on X (Twitter), he argued that recent and upcoming updates align decentralization, security, and scalability through code implementing them in production. ZK-EVMs are currently in alpha stage (operational with production quality, security stage still ongoing), and PeerDAS has gone live on the main network. It now becomes more meaningful to discuss what this combination means for Ethereum.

At the core of these claims are two technical advancements: PeerDAS and zkEVM. Additionally, validator exits, which occur in minutes, are slowing down, while a new flow of capital for long-term locked assets signals a significant behavioral change among major ether holders. Validator exit queues dropped to zero on Tuesday; this indicates a dramatic drop from the approximately 2.67 million ETH exit wait time expected in mid-September.
