summary

This article follows our previous articles about EIP-4844, using data and insights in the emerging BLOB market for analysis.The article focuses on the BLOB release strategy used by BLOB producers such as Optimism and Base, and quantitatively analyzes the strategy efficiency indicators, such as the speed of BLOB incorporated into the block and the priority premium paid for this.

Blob market utilization rate

As of April 16 (Dencun upgraded for one month), about 40% of the blocks contained Blob.Because the average BLOB cost is still at the lowest level of 1 wei (the target of the average of 3 BLOB per block), the number indicates that the market is not saturated.

In the last week of March, because the BlobScriptions temporarily pushed the Blob market to the full load operation, the basic cost of Blob once exceeded the basic cost of the block.

At present, the upper limit of the BLOB released per hour is about 400.The saturation point of Ethereum data availability market is about 900 BLOB per hour (to meet the goals of 3 BLOB per block), which shows that the market currently only uses 40% of the capacity.

900 BLOBs per hour are preset 3 BLOB target values ​​(Reference Source:https://dune.com/hashd_official/blobfarmTo.

Flashbots’s Blob-Block Constructioner instrument panel provides BLOB data insights at the built-in device.Since 40% of blocks contain BLOB, we can securely assume that the BLOB income rate of the builder should also be around 40%.

At present, the BLOB income rate of 20% of the builders with a total output of the block is lower than expected, ranging from 1% to 16%, which shows that due to the lack of incentive measures predicting in an article before EIP 4844, the builder may mayDelayed.

Among the top 7 builders who occupy 96% of Ethereum blocks, the builders (20%), which ranked 3rd and 7th in the market share, showed that the Blob’s concentration rate in the block was much lower.This shows that due to the lack of economic incentives, they abandon BLOB transactions when building block content.

The block built by ordinary verification device (we define it as a verification device that builds its own block) has fewer MEV opportunities, so there are few precedents including and delayed economic competition.These verifications usually do not run the code optimized code.Because these verifications build their own blocks, there is no longer a time -time time game with BLOB dissemination delayed through relay.Most other top builders remain similar to the BLOB included as ordinary verification, which shows that it is good for the BLOB market.However, it remains to be observed whether this altruistic strategy is effective during the period when the MEV competition is fierce.

Optimism and basic blob strategy insights

At present, Optimism and Base use BLOB to maximize the strategy -each transaction releases up to 6 BLOB at most, in fact, the BLOB space of the block is filled with a single type 3 transaction.The advantage of submitting 6 BLOB in each transaction is that the GAS cost can be reduced to the greatest extent.The cost only needs to be paid once, rather than paying the basic costs of 6 trading blocks for 6 BLOB.

This strategy increases the Blob Gas up to 12.5%, resulting in a higher cost of Blob Gas in the next block of Blob.如果不同的rollup 一次仅发布1 个blob，并与大小为6 blob 的交易共享内存池，根据blob 的Gas 成本，对于rollup 来说，尝试前置运行基本blob 交易并避免12.5% 可能会更有利斑点Increase costs.虽然由于 blob 争用较低，目前节省的金额可以忽略不计，但如果该策略成立，blob front running 可能是未来节省成本的可行策略。This also means that other people who use this strategy may be reviewed by other BLOB blocks submitted by other summaries or inscription users.

Base is currently the largest user in the BLOB market, followed by Arbitrum and Optimism.Overall, the strategies used by Optimism and Base account for about half of the BLOB market utilization rate.We emphasize that the market has not been fully utilized at present, so competition between market participants has not intensified.

BLOB income rate analysis

The validity of the above BLOB release strategy can be measured through grooves and correlation between the premium premium premium premium premium and the inclusion rate of the EIP-1559.

The first measurement is the containing rate.This means the number of time clearance required to include the blob in the beacon chain. The higher the rate, the slower the time.The best slot includes 1, which is included in a single block.However, because BLOB traverses the memory pool slowly as a very large transaction, we believe that the two grooves are used as acceptable grooves.

The second measurement standard is to understand the correlation between the EIP-1559 premium premium premium and the faster period of time.Ideally, higher priority expenses will lead to faster slot inclusion rates.

Block income rate

尽管市场利用率不足（下文图表可见），Optimism 和 Base 的 Blob 纳入率仍然相当缓慢，经常出现高于2个区块的峰值。At first glance, BLOB incorporated in a market without loading seems to be violating intuition.

EIP-1559 Priority cost premium premium and slot incoming rate correlation

Optimism and Base’s bidding strategy follows the Geth specification, that is, double the parameters when the blob is submitted.下图显示，这种出价策略对加快槽纳入没有显着影响，即使优先费用高达40 gwei，有时也需要超过10 个区块才能被纳入，而低至2 gwei 的优先费用有时也可以在单个区The block was included.

What is unclear and reliable? What is the best priority fee required?Generally speaking, Blob’s stagnation in the memory pool is not beneficial.The slower groove income rate will increase the uncertainty of the price differences around GAS, the choice of rotation builders, and the occasional MEV opportunity.

The blob market adopts and expand

Blob 市场仍处于萌芽阶段，其采用仍在进行中 – Scroll 最近采用了 EIP-4844，zk rollup 如 Aztec 和 Taiko 计划在今年晚些时候上线主网。According to L2Beat data, Rollup using Ethereum CallData as the availability layer is more than using Blob.

In addition, BLOB describes that non -RollUp users are more likely to access the Blob space through the predecessor UI that is easy to use.After opening the BLOB description, we saw that the BLOB market quickly reached capacity, although the later activities have decreased.

After EIP-4844, the next main technical steps used to expand the BLOB use are to implement a complete shard after the potential increase of target value 3.Implementing data availability sampling technology will enable the current BLOB market to expand from 6 BLOB to 64, and ultimately expand to 256 BLOB.

Blob market outlook

For BLOB producers who seek a reasonable block income rate, it is currently limited to the highest priority cost of using the EIP-1559, but this is not an effective parameter, because the priority cost and the faster BLOB incoming rate are not significant.Correlation.In addition, because the entire BLOB needs to be submitted to the memory pool, the update speed of the priority fee is very slow.随着 Blob 采用率的不断上升，我们预计随着带宽使用量增加和纳入反馈速度变慢，将更难以依赖这种竞价机制。

As the BLOB market matures, it will require more complicated bidding strategies to ensure that the availability layer of data on demand is required.Primev has been paying close attention to the Blob market and proposed that the BLOB pre-confirmation of MEV-COMMIT as a feasible solution included in a reliable BLOB.If you are a BLOB producer or other interesting Ethereum participants who are interested in optimizing BLOB, please contact our team to participate in our experiments with our team.
