What does the Blob upgrade and validator staking cap increase bring to Ethereum?
Written by: Pzai, Foresight News
The Ethereum Pectra upgrade was conducted on May 7 at 18:05, which is the first upgrade of to thenet the cancun March, including two collaborative updates: Prague execution layer hard fork and Electra consensus layer upgrade, and plans to incorporate 11 Ethereum Improvement Proposals (EIPs). Several important EIPs in this upgrade include EIP-7251 (increasing maximum validator effective balance), EIP-7691 (Blobspace throughput improvement), EIP-7623 (increasing call data fees), etc. This article will and analyze from a data perspective.
Blob Upgrade: Stepping into the "Super Execution Layer"
At the ETHAsia 2025 event, Vitalik stated that the Pectra upgrade will increase Blob capacity from 3 to 6. Currently, 3 Blobs are approximately 375kb, generating 375 kb of data every 12 seconds, which is about 20kb per second, corresponding to a TPS of around 250; if Blob capacity increases to 6, TPS is expected to rise to 500. However, Blob capacity expansion largely depends on the Fusaka upgrade expected to be implemented in the third or fourth quarter this year. In an ideal scenario, the Fusaka upgrade could increase Blob capacity to 48; if DAS (Data Availability Sampling) is fully implemented, Blob capacity could reach up to 512, potentially increasing Ethereum L2 TPS to tens of thousands.
From on-chain data performance, the Pectra upgrade, submissions have slightly fluctuated, rising to 3.6 after the3upgrade confirmation, but overall still not reaching reaching half of the design level. However, Valsoitalstated in his speech that despite that L2's rapid development, improving L1's scalis crucial to achieve anti-censorship and cross-L2 asset asset transfers. In. the future, as L2 bears massive transaction processing, L1's Blob will inevitably face pressure, and under current market conditions, L2L2continuous development is is is also potentially nourishing L p p img src static="..io/img/0923e49e a835bb904adf684b5cf455d.jpg5.jpg">
>Validator StSimple Path"EIP-7251 increases the maximum effective validator balance from 32 ETH to 2048 ETH, allowing allowing reward compound interest and validator integration. consolidation. On Beaconchain data, existing validator balances are between 32-38 ETH, with the highest balance reaching 70 ETH, far from the 2048 ETH hard cap.
In'sidityaking Loperates 286,000 validators, with an average validator allocation of of 32 ETH. validator expansion, expected to reduce 64-fold to around 4500. This means institutional validators will manage fewer nodes, reducing hardware and maintenance costs. However, some Ethereum critics warn that this measure might exacerbate centralization and reduce the network's risk resistance level.
Additionally, EIP-7002 in the Pectra upgrade allows triggering validator exits and withdrawals on the mainnet, reducing reduces dependence on active keys of validator operators, which as "hot" keys are easily attacked. In, EIPh-7002 enables credentials to initiate validator exits,,assing layer active key requirementsive.
Ethereum's Way Out?Under the2trend, Ethereum validatorators' is facing multi-dimensional shrinkage: on one hand, Blob expansion and low chain activity reduce transaction fees; on the other hand, cryptocurrency price fluctuations have decreased USD-denominated staking returns. Consequently, Daily income from $10 000 to less than $5$5 in the year. The income reduction may impact network staking growth, and this EIP-7251 implementation might accelerate validator scale reduction.
After the Pectra upgrade, Ethereum is currently priced at $1912.29, with a daily increase of 4.38%. For, users,,, is not just a for Ethereum's price, but also paves future. ethereum. In recent articles, Vitalik hopes Ethereum as simple as including Bitcoin in five years, including simplifying consensus layer, simplifying execution layer, VM transition backward compatibility, and simplification through shared protocol components.. We also hope the Ethereum continuerive Bitcoin.
