Blob-First Rollups: Re-architecting Data Availability After EIP-7691

Summary: So, on May 7, 2025, Ethereum launched the Pectra upgrade, and it came with EIP-7691 as part of the package. This upgrade basically doubled the blob capacity and totally shook up the economics of how Layer 2 data availability operates. In this post, we’re diving into what all this really means when it comes to the architecture, pricing calculations, and some down-to-earth strategies for rolling things out. If you’re building on rollups or just curious about them, you’re in the right place! (blog.ethereum.org).

TL;DR for decision‑makers

Hey there! Just wanted to share some cool news: EIP-7691 has increased Ethereum's blob targets and maximums from 3 and 6 to 6 and 9 blobs per block. Exciting times for the Ethereum community! This update features a revamped fee curve that makes things way more responsive. It really enhances data availability (DA) on Layer 1 for rollups, which is pretty exciting! For all the details, feel free to take a look here: eips.ethereum.org.

In the first week after the fork, we noticed that the actual demand for blobs wasn't quite hitting the new target we set. So, because of that, the fees for blob "objects" really took a nosedive, heading back towards zero. This was great news for L2 margins, even though end-user fees didn’t drop any further. If you want to dive deeper, check out this article: (galaxy.com). It’s packed with good info!

These days, with "blob-first" architectures, we're really starting to reap the rewards. We're talking about things like batching to make the most of our blobs, smoothly switching between blobs and calldata on the fly, and having multi-DA fallbacks ready to go. It's pretty exciting stuff! Basically, this means we’re looking at lower costs that are easier to predict, along with a boost in resilience compared to what we had before EIP-7691. If you want to dive deeper into this topic, check it out here: docs.arbitrum.io. You’ll find all the details you need!

1) What EIP‑7691 changed--and why it matters

So, back on May 7, 2025, they introduced EIP-7691 alongside Pectra, and let me tell you, it seriously ramped up Ethereum’s blob throughput! They bumped up the target and maximum blobs per block to 6 and 9, respectively. They also made some adjustments to how the blob base fee reacts. So, what does this mean for you as a user? Well, you get access to more “blobspace.” This basically means there’s less scarcity, which is pretty great! And when demand drops, you’ll notice that fees decline faster. Check out these important parameters and their effects: (blog.ethereum.org).

Target blobs per block: Now we're looking at 6 blobs per block, which is an increase from the previous 3.
Maximum blobs allowed in each block: Now 9, up from the previous 6. So, I've been checking out the latest updates on the fee structure, and honestly, it’s pretty intriguing. The way the base fee adjusts isn’t your typical setup, which adds an interesting twist! When the blocks get really crowded, you’ll see the blob base fee spike by around 8. You get 2% for every block that's filled in. On the other hand, if there are any empty spots, the number tends to drop by about 14. 5%. This little adjustment is all about keeping prices affordable, unless we're dealing with consistent congestion. (eips.ethereum.org).

Blobs are this awesome feature that rolled out with EIP-4844, which launched on March 13, 2024. So, this latest update introduced a special DA lane just for rollups. It can handle around 128 KiB per blob, and it offers an availability window of about 18 days at the consensus layer. Pretty cool, right? If you want to dive deeper into the details, just click here. Happy exploring!

After Pectra came into the picture, the daily blob capacity took a big leap from around 5. You're looking at a jump from about 5 GB a day to roughly 8 GB. 15 GB/day. During the first five to seven days, rollups managed to snag around 25. You’re looking at about 6,000 blobs a day, which breaks down to around three blobs each minute. You're currently using about 3 GB a day, which is just a little short of the new target rate. As a result, blob objects became almost free, and we noticed a big drop in net L2 DA spending. (galaxy.com).

For execs, the takeaway is straightforward: Ethereum's main decentralized application has really expanded and, on the whole, it’s become more budget-friendly again. This really helps to boost your L2 margins and gives you a lot more flexibility, all without having to change your settlement chain.

2) The blob market after 7691: what the numbers say

Capacity: So, here’s the deal: we’re aiming for 6 to 9 target/max blobs, and each blob is 128 KiB. That gives us plenty of breathing room to keep our data available consistently. If you want to dive deeper into it, feel free to check it out here!
Usage and price: Once Pectra launched, we noticed a nice jump in demand--about 20-22%! But even with that boost, we're still not quite hitting our target. So, it turns out blob object fees have really dropped down to almost nothing, which is awesome news. Plus, the amount of ETH being burned from Layer 2 data availability has seen a massive drop of about 70% week over week, according to some early stats. Pretty interesting, right? If you're looking for more info, you can check this out here. It's a pretty handy resource!
Node pressure: So, it looks like there’s been a rise in blob purchases lately. Because of that, consensus nodes are currently dealing with a maximum load of about 44. During an 18-day stretch, we ended up with 6 GB of blob data. As long as everything’s still under control, it’s a good idea to stay alert and keep an eye on it. If you're looking for more info, check it out here. There's some interesting stuff waiting for you!

At the user level, a bunch of Layer 2 solutions have already introduced EIP-4844 savings. If you’ve noticed those ridiculously low fees on platforms like Optimism and Base, that’s exactly what I’m talking about! The main idea behind 7691 is to give sequencers and L2 operators a little extra breathing room while also helping them keep their costs in check. (coindesk.com).

3) Blob‑first architecture: how modern L2s should post data now

Blob-first is all about making Ethereum's blobspace your top pick for data availability (DA). What it means is that you're setting up your batching and derivation process with the main goal of maximizing those blobs. You'd typically only make the switch to using calldata or external DA if it actually saves you money or if there's a solid operational reason to do so.

3.1 Embrace blob‑native batching and packing

Fill rate: Aim for your batcher to hit at least 95% fullness for each blob. It's a good goal to keep everything running smoothly! Once you’ve done the encoding, you’ll end up with an effective payload of about 127,228 bytes instead of the raw 131,072 bytes. So, it’s a good idea to tweak your frame sizes and headers to give yourself a little buffer. Better safe than sorry, right? Hey, take a look at this: (gist.github.com). You won’t want to miss it!
Compression tuning: It’s all about striking the right balance between your zstd compression level and how much CPU power you can spare. You want to maximize those blobs without causing a lag in performance. The Arbitrum Nitro docs really make it easy to understand: sure, cranking up the compression can definitely cut down those L1 posting costs, but just keep in mind that it can also nibble away at your throughput headroom. More details here: (docs.arbitrum.io).
Time vs. Size Triggers: Consider setting up dual thresholds--like, you could have your system flush when your effective blob payload reaches 98%, or after a specific number of seconds have passed. This way, you can avoid those pesky under-filled blobs when traffic is light. It's a neat trick to keep things running smoothly!

3.2 Price‑aware blob vs. calldata switching

Why it’s important: So even if we’re talking about something like 7691, those little spikes can seriously drive up the blob base fees. Alright, so your batcher has to weigh these two calculations. Alright, so when we talk about blob costs, here’s the deal: it’s calculated like this: you take the baseFeePerBlobGas, multiply it by GAS_PER_BLOB, and then add in the gas for an EL type-3 transaction. Simple as that! So, when you're looking at calldata, it's basically going to cost you bytes times (4/16 gas per byte). Just keep in mind, if you're settling into a network where 7623 or 7976 are active, the gas cost might be a bit higher. ` (eips.ethereum.org).
Implementation patterns: Arbitrum keeps things pretty simple for you. They offer some easy-to-use options, like switches for post-4844-blobs and a flag to ignore blob prices. These give you the flexibility to push for blobs or switch to more budget-friendly options when necessary. This model is definitely worth considering when you're putting together your own custom stacks. (docs.arbitrum.io). So, with the latest Ecotone upgrade for the OP Stack, they've introduced a new pricing feature for L1 data fees, plus they've also revamped the L2 GasPriceOracle. Pretty cool changes! It’s a great idea to factor in the actual L1 DA costs when you're figuring out your sequencer’s finances and the fee estimates your users get. (gov.optimism.io).

3.3 Use the right signals in your oracle

If you're diving into L1 (Ethereum) and want to look into blob fees, contracts, and off-chain services, you can definitely take advantage of: So, there's this BLOBBASEFEE opcode that came about thanks to EIP-7516. It's pretty handy because it tells you the current base fee for blob gas in a block, which can be super useful for keeping your accounting in check. If you want to dig deeper, check this out: eips.ethereum.org.

So, when you're checking out the eth_feeHistory fields, make sure to pay attention to baseFeePerBlobGas and blobGasUsedRatio. They can really help with making some smart estimates for the future! This can be super useful, especially when you think about sliding windows over the most recent N blocks. Take a look at this link: (docs.metamask.io). It's got all the info you need!
So, when you're dealing with L2s like Linea, you'll notice that BLOBBASEFEE tends to be set at a pretty low minimum. It's probably not the best idea to rely on L2 opcodes for L1 pricing. When you're figuring out those DA costs, just go straight to L1 for your info. If you want to dive deeper into the details, just check this out: (docs.linea.build). You'll find everything you need over there!

3.4 Operate a resilient Beacon‑aware data layer

So, blobs are connected to the consensus layer and are referenced by the Execution Layer (EL). That makes it really crucial for your nodes to maintain a strong connection to the Beacon network to snag those blob sidecars. The OP Stack really shows how important it is to either run a consensus client yourself or connect with one, like Lighthouse, Prysm, or Teku. Don’t forget to add this to your production runbooks! (docs.optimism.io).

Hey, just a quick reminder about retention planning! So, those blobs? They start getting pruned after around 4096 epochs, which is about 18 days. Just something to keep in mind! It's definitely a smart move to hang onto independent archives of batch payloads even after that date. You never know when you might need them for reorgs or any legal matters that might come up down the line. Better safe than sorry, right? Don't forget to set up some alerts to give you a heads-up if the sampling or retrieval starts to go off track. It's always good to stay in the loop! (ethereum.org).

4) Pricing the new world: exact math and planning ranges

Use Clear Formulas in Your Treasury and Sequencer Logic

When you're dealing with treasury and sequencer logic, it's really important to keep your formulas clear and easy to follow. This really helps everyone get a good grasp of the nitty-gritty details behind how everything ticks.

Key Reasons to Use Explicit Formulas:

Clarity: Having detailed formulas really helps clarify the reasoning behind your choices. It's like having a roadmap that makes it super easy to trace your steps and understand where you’re coming from.
Consistency: Sticking to a standard method for showing your calculations helps make sure everyone understands things the same way. It keeps us all on the same wavelength!
Debugging: Keeping things clear and straightforward really helps you catch any mistakes or problems in your thinking.

Example of Explicit Formulas

Let me give you a quick example to show you what I'm talking about. Imagine you’re working out the total treasury balance by considering a few different factors. Instead of just saying, "the treasury balance is calculated based on various inputs," you could break it down a bit more like this:

# Calculate total treasury balance
total_balance = initial_balance + revenue - expenses

Tips for Implementing Explicit Formulas

1. Go for Descriptive Names: It’s super helpful to give your variables names that actually tell you what they stand for. That way, it’ll be a lot easier to understand what’s going on in your code! 2. Comment Your Code: Don't forget to throw in some comments to clarify any tricky logic or calculations. This will make it way easier for anyone (including your future self) to understand what's going on! 3. Keep It Simple: Try to break down those complicated formulas into smaller, bite-sized chunks whenever you can. It makes everything way easier to handle!

If you stick to these guidelines, you'll find that your treasury and sequencer logic becomes a lot clearer. Plus, you'll be helping foster a more collaborative and efficient vibe in the development team.

Constants:
- GAS_PER_BLOB = 2^17; So, if you break it down, each blob is made up of 4096 bytes multiplied by 32, which gives you a total of 131,072 bytes. Pretty neat, right? The effective payload is roughly 127,228 bytes. (eips.ethereum.org).
Cost for Blob Objects (ETH per blob): To figure this out, you just take the baseFeePerBlobGas (in wei), multiply it by 131,072, and then divide that by 1e18. Easy peasy! Alright, let’s dive in and take a look at a few examples! So, if you’re starting from just 1 wei, which is basically the lowest you can go with the protocol, you're looking at around a cost of 1. Pretty straightforward, right? It’s just 31e‑13 ETH per blob, which is pretty much nothing! (eips.ethereum.org). So, when it hits around 1 gwei, that’s about 0. 000131072 ETH per blob. When it hits 50 gwei, it pretty much shoots up to about zero. 0065536 ETH per blob. Make sure to keep an eye on the ETH/USD rate so you can budget effectively. And hey, remember to factor in the EL execution gas for those type-3 transactions too!
Calldata Fallback Cost: So, here’s the deal: currently, the cost breaks down like this: (zeroBytes × 4 + nonZeroBytes × 16) gas. Just a quick heads up, though - those costs are likely going to climb a bit. We’re looking at around 10 to 40 gas per byte under EIP‑7623, and it could even reach 15 to 60 with EIP‑7976. This is all part of the shift towards using blobs for better data availability in the ecosystem. Just something to keep in mind! Just a heads up to keep these numbers in mind as you figure out your switch thresholds. (eips.ethereum.org).

So, when it comes to tweaking the emerging markets, we’ve got some cool stuff on the table. The proposals for the minimum blob base-fee (that’s EIP-7762) and a few related designs (EIP-7918) are focused on speeding up price discovery and keeping blob fees under control, especially during those wild demand spikes. Pretty neat, right? They might not really shake up the average costs too much, but they definitely impact the tail behavior. That's why it's crucial to include these scenarios in stress tests. Take a look at this: (eips.ethereum.org). It's worth checking out!

5) Interop with alternative DA: why “blob‑first,” not “blob‑only”

Ethereum's blobspace is really coming along nicely--PeerDAS is on the way to ramping up data availability scaling. That said, we can’t forget about the specialized data availability layers like EigenDA, Celestia, and Avail. They’re still super important if we want to hit those high throughput numbers and keep costs predictable. A clever move for 2026 might be to start with a "blob-first" approach and have a multi-DA backup plan. "Take a look for more info on this over at eips.ethereum.org. You’ll find all the details you need there!"

When to choose external DA: Hey there! So, if you're in the market for some reliable multi-MB/s posting--especially if you’re dealing with those high-TPS chains--you might find that even Ethereum after PeerDAS could have a tough time keeping up with the heavy workload. Just a little heads-up! That’s why you’ll find teams like MegaETH diving headfirst into EigenDA. Take a look at this link: (megaeth.com). It’s definitely worth checking out!
Perhaps you're looking for pricing that doesn't get caught up in those L1 fee cycles, or maybe you're interested in faster finality options. Make sure to check out L2BEAT’s DA throughput dashboard to see who's sharing their stuff and where it's happening these days! It's a great way to stay in the loop! Find it here: (l2beat.com).
Architecture pattern:
Kick things off with Ethereum blobs as your first choice. If you notice that the baseFeePerBlobGas times the number of blobs you need is getting close to your SLO budget, or if your Beacon endpoints are acting wonky, it's a good idea to mix things up. Try routing to a backup DA that has a proof or attestation saved on Layer 1. It could save you some headaches! Hey, just a quick reminder to keep your merklized payloads consistent across all the DA backends, okay? It’ll help everything run smoothly! Want to dive deeper? Check it out here: docs.arbitrum.io. It's got all the details you need!

6) What the leading stacks are doing (and what to copy)

Arbitrum: They’ve really kicked things off with blob posting! Now you can adjust the settings to either prioritize blobs or just stick with the default calldata option. Pretty cool, right? Here are a couple of handy operational flags you might want to keep in your back pocket: ignore-blob-price and the timing/caps for blob-tx replacements. They could really come in handy! Oh, and guess what? There’s a handy template just waiting for you to use with those custom batchers! Take a look at the details in the docs. You’ll find all the info you need there!
OP Stack (Ecotone): They've rolled out a fresh L1 data fee feature and made some updates to the GasPriceOracle. Pretty interesting stuff! If you're using a Beacon client, you can easily adjust your fee oracle to gather blob metrics by using eth_feeHistory. Get the details here.
Base/OP/Arbitrum: So, ever since the Dencun upgrade rolled out, those big Layer 2 solutions have really cut back on fees--they're now just a few cents! After the post-7691 update, operators found a way to squeeze out some extra margin, even though the fees for end users stayed pretty much the same. This opens up some exciting opportunities--now there's a chance to reinvest those savings into boosting reliability or even accelerating growth! If you want to dive deeper into this, check out the article over on CoinDesk. There's some great info there!

7) Operational playbook and SLIs/SLOs

When you're getting ready to launch your blob-first strategy, don’t forget to keep an eye on these key metrics and guidelines:

SLI: Our goal is to have those blobs packed at least 95%. So, we’re making sure that the under-filled blobs stay below 5% of our daily volume.
SLI: We're aiming for a blob posting failure rate that's less than zero. We're looking at a 1% here, but we also need to stay on top of our average time to replace (RBF) for those type-3 submissions. It's important to keep that in check!
SLI: For our beacons, we’re aiming to keep the p95 sidecar retrieval latency under 2 seconds, and we want to make sure the error rate stays at zero. 5%.
SLO: We’re keeping an eye on how much each batch costs across three different traffic levels--low, medium, and high. To do this, we’re using thresholds derived from the baseFeePerBlobGas percentiles from eth_feeHistory. Check it out here.

Operational controls:

Operational controls are super important for keeping an organization running smoothly and efficiently. They help keep things running smoothly on a daily basis while making sure everything lines up with the organization's bigger picture. Let’s dive into some important operational controls. Here's a quick rundown:

1. Standard Operating Procedures (SOPs)

These really form the backbone of how we keep things running smoothly. SOPs are basically step-by-step guides that show you exactly how to tackle certain tasks. They really help keep things consistent and ensure everything stays top-notch. If you're interested in learning how to create effective SOPs, check this out here. It's got some great tips!

2. Performance Metrics

It's super important to keep an eye on your performance metrics if you want to see how well everything's running. Metrics can cover a variety of things, like how productive a team is, the number of errors made, and even how happy customers are with a service. Keeping an eye on these numbers can really help you spot the areas that could use a little TLC.

3. Internal Audits

Doing regular internal audits is a great way to spot any inconsistencies and make sure everything's in line with the policies and regulations. They help keep things running smoothly! They’re a fantastic way to see how your processes are really working from a fresh perspective.

4. Risk Management

Spotting potential risks and having a game plan to tackle them is a key part of keeping operations running smoothly. Don’t forget to keep an eye on both internal and external threats to your operations. It’s important to check in regularly to stay on top of any potential issues.

5. Training Programs

Investing in training for your team is super important if you want to keep everything running smoothly. It really helps ensure that operational controls are on point. Help your team build the know-how and skills they need to really thrive in their jobs.

6. Feedback Mechanisms

Setting up a system to gather feedback from both employees and customers can really give you some great insights. When you take the time to really hear from the folks who are out there doing the work--whether through surveys or suggestion boxes--it can spark some awesome changes. Their insights can really make a difference!

Just a reminder: having solid operational controls really comes down to being proactive and making smart choices!

It has a dual-trigger flush system, so you can choose the size and timing that works for you, plus you can adjust the compression levels to suit your needs. (docs.arbitrum.io).
Automatically directing blobs and calldata by comparing costs and latency in real-time. (docs.arbitrum.io). So, here’s the deal with the cold-path re-publisher: if for some reason pulling data from Beacon doesn’t pan out, it’ll send the batch payload over to a backup store. Picture this as a mix of object storage and content addressing. This way, independent auditors can dive in and check things out until those proof windows close. Pretty cool, right? (ethereum.org). So, canary posting isn't something we do all the time. We keep it low-key to monitor the Beacon RPCs and check that everything’s on track with commitment verification, even during those slower periods.

8) Compliance and risk considerations for enterprises

Retention guarantees: So, Ethereum ensures blob availability for roughly 18 days. If your dispute window stretches beyond that, it’s a good idea to have your own records and audits on hand. You never know when you might need them! For more info, just check it out here. You'll find all the details you need!
Regulatory evidence: Since blobs are pruned, make sure your compliance proof shows both your L1 commitments and how you’re storing that off-chain payload. Just a quick reminder to make sure you double-check that the hash chains are linked up with the type-3 transactions that were posted. It’s important for everything to line up! If you're looking for more details, you can check it out here.
Change Management: So, make sure you're staying updated on calldata repricing! EIP-7623 is already rolling out on a few networks, and there’s a proposed EIP-7976 in the works too. Oh, and don’t forget to check out the minimum blob fee proposals (that's EIP-7762). It's definitely worth keeping tabs on these changes! These changes can seriously affect your fallback economics and how you manage stressful situations. If you want to dive deeper into it, just click here for more info!

9) What’s next on the roadmap (and how to prepare)

PeerDAS (EIP‑7594): So, here’s the scoop - data availability sampling via the P2P layer is currently in its Last Call phase. The goal here is to significantly boost data availability while keeping the strain on nodes to a minimum. Exciting stuff! As time goes by, keep an eye out for those bigger blob targets. It’s super important to make sure your batcher can adapt to these changes as they come along. (eips.ethereum.org).
Uncoupling Parameters (EIP‑7742): So, with this update, the execution layer is now able to snag the blob target directly from the consensus layer. This is a big deal because it sets us up for faster tweaks down the road! Hey engineers, it's best to avoid hardcoding any assumptions about fee oracles. (eips.ethereum.org).

So, it looks like Ethereum is gearing up to move data availability from calldata to blobs. That means we should expect to see an uptick in calldata floors, jumping from 7623 to 7976. Just a heads up--make sure your fallback strategy is rock solid! (eips.ethereum.org).

10) A concrete 30‑60‑90 day plan

Days 1-30:
Alright, let’s kick things off by getting those dashboards for blob fullness, baseFeePerBlobGas, and blobGasUsedRatio up and ready to roll! By the way, make sure to set up eth_feeHistory in your fee oracle! It’s super important not to skip that one. If you’re looking for all the details you need, just check this link here. It should have everything laid out for you! Alright, next up, let’s go ahead and turn on blob posting in our staging environment by using the forced-blob mode. Let’s take a look at the near-full packing situation and make sure that the end-to-end blob sidecar retrieval is running without any hiccups. If you’re looking for more info on that, check it out here. You'll find all the details you need!
Days 31-60:
Alright, we’re at the point where we can start implementing price-aware routing, which is all about choosing between blob and calldata. Just a heads up though, we’ll only move things up to secondary DA if we find a policy breach. Just a heads up--don't forget to double-check your accounting by using BLOBBASEFEE in those L1-aware components. It's super important to keep everything in check! If you want to dive deeper into it, feel free to check this out here. It's packed with info!
And hey, let’s tweak those compression and flush thresholds a bit so we can make sure those under-filled blobs stay below 5%.
Days 61-90:
To wrap things up, we're excited to roll out a multi-DA pilot that will feature options such as EigenDA and Celestia. We'll also be incorporating L1 commitments and deterministic batch hashes for added security and efficiency. Hey, just a quick reminder to run those failure-injection drills. It's a good way to check for any potential Beacon outages, so we can stay on top of things! If you're looking for some extra insights, just check this out here. You'll find some useful information!

11) FAQ: common executive questions

So, do you think user fees will go down again after 7691? Yeah, it could happen, but there are no guarantees. The latest info shows that blob object fees have really dropped--almost to zero, actually--since the demand hasn't quite matched what people were hoping for. Still, quite a few Layer 2 solutions have figured out how to keep their user fees in check while still turning a profit. You can put that extra cash to good use by investing in growth, offering rebates, or just making things more reliable. If you're interested, you can check out more details about it here. It’s definitely worth a look!

Hey there! Just wondering, is calldata still a thing? For sure! It’s still a solid backup and comes in handy for those non-DA applications. It looks like the atmosphere in Ethereum governance is changing, and people are starting to lean more towards blobs (7623/7976). Think of blob-first as the new standard now, with calldata serving as our safety net. It feels like we've shifted gears, right? (eips.ethereum.org).

So, how do we keep track of blob fees? You can take a look at the BLOBBASEFEE on Layer 1 for some in-block accounting. Plus, using the baseFeePerBlobGas and blobGasUsedRatio from eth_feeHistory can really help you get a handle on forecasting. (eips.ethereum.org).

No matter if you're just starting out or you're already a big player in the game, jumping on board with a blob-first rollup is a smart move. It’s designed to fill those blobs efficiently, adjust route pricing on the fly, and provide a multi-DA escape hatch. This strategy can really help you save some cash, improve your profit margins, and make your operations smoother as we see Ethereum’s DA roadmap come to life--think along the lines of PeerDAS and what’s next!
