Can you explain how rollups or sidechains differ from purpose-built real-time settlement platforms in terms of throughput and cost?

Summary: Hey there! In this guide, we're going to take a closer look at how Ethereum rollups and sidechains stack up against dedicated real-time settlement layer 1s. Let's get into it! Let’s dive into two major factors that really influence user experience and the overall economics: throughput and cost. We're diving into the most up-to-date post-Dencun data, and we’ve got some great configuration tips to share. Whether you’re just starting out or you’re part of a big enterprise team, we’ve got some handy playbooks to help you make the best selections.

TL;DR for decision‑makers

If you need fast user confirmations and affordable micro-payments on a large scale, you can’t go wrong with a specialized real-time Layer 1 like Solana, NEAR, Avalanche, XRPL, Hedera, or Stellar. These options really shine when it comes to speed and keeping costs low. You can look forward to those transactions wrapping up in just a few seconds, and the costs? They’re only a tiny fraction of a cent each! If you want to dive deeper into it, just head over to solana.com and check it out!

On the other hand, if you’re looking for that solid Ethereum security and an easy way to dive into the EVM ecosystem, modern rollups have gotten really affordable since EIP-4844 came into play. Plus, they can scale horizontally, which is a nice bonus! Just a heads up, their long-term throughput has a few hiccups because of data-availability (DA) constraints. Plus, they've got to deal with some Layer 1 settlement latency too. Sidechains can be a faster and more affordable way to work compared to Layer 1 Ethereum. However, they do have their own set of risks since they rely on their own consensus mechanisms and trust factors. Keep that in mind! If you want to dive deeper into it, check out this link: eips.ethereum.org. There's a lot of great info waiting for you there!

Alright, let’s break down how these differences can affect your throughput headroom and transaction costs. Plus, I’ll share some tips on what you can do right now to make the most of either stack.

What “throughput” and “cost” really mean in 2025

Throughput: Think of this as the number of user actions your system can juggle every second without making things feel sluggish or frustrating for anyone. When it comes to rollups, the main thing you need to keep in mind is the Data Availability (DA) capacity of Layer 1. Basically, it’s all about how many blobs you can fit into each block, along with how you've set up your batcher. When you're talking about monolithic L1s, the big focus is on how much bandwidth the validators have and how fast they're cranking out blocks. (eips.ethereum.org).
Cost: Let’s talk about the extra costs that pop up with each transaction, like those pesky fees! You also have to think about what you’re shelling out for your own setup and any DA fees that come into play. After the 4844 update, when it comes to rollups, the biggest expense boils down to how much "blob data" you have for each transaction multiplied by the blob gas price. When it comes to real-time Layer 1s, you'll usually see base and priority fees. These fees are often expressed in the Layer 1 token itself or in USD if you're using Hedera. (eips.ethereum.org).

Rollups: how much throughput and how cheap, really?

The DA ceiling after EIP‑4844 (Dencun)

Hey there! So, EIP-4844 has introduced these really interesting “blob” transactions. How cool is that? So, each blob is roughly 128 KiB, and Ethereum can process up to 3 blobs every 12 seconds, with a total cap of 6 blobs. So, right now, we're seeing about 32 to 64 KiB/s of budget-friendly L2 data capacity for each slot. That’s the treasure trove of resources that rollups are competing for. (eips.ethereum.org). Hey, just wanted to share some exciting news about the data availability (DA) lane - things are really picking up! According to L2BEAT, we've seen blob capacity utilization soar over 80% lately. Interestingly, one L2, known as Base, seems to be leading the pack more often than not. Pretty cool stuff, right? Basically, the number of sustainable transactions per second (TPS) for your L2 really depends on how effectively you can pack those transactions into those blob bytes. (l2beat.com).

Basically, what this means is pretty simple: The way you handle batching and compression really affects how many transactions per second (TPS) you can get. Let’s take Arbitrum Nitro as a great example. It uses Brotli compression for its batches and figures out the cost of each transaction by looking at how much L1 data it’s estimated to use. The better you are at compressing, the more transactions per second (TPS) you can hit without going over your blob budget. (research.arbitrum.io).

What 4844 did to fees

Moving data from calldata to blobs has really helped some rollups cut their fees down by an impressive 50 to 98%. Pretty amazing, right? These days, you can typically expect to fork over just a tiny fraction of a cent to a few cents for basic transfers. As for swap fees, they usually hang out in the low-cent area, but it all depends on how busy the network is at that moment. (thedefiant.io).

Practical Rule of Thumb (Post-Dencun)

If you're making a simple ERC-20 transfer on a major optimistic rollup, expect to shell out less than a buck. 01 during quiet times. When things get hectic, you might find yourself needing to spend a few cents here and there. And if you're looking to make some swaps, be ready to chip in a few cents for those too. Make sure to keep an eye on the price of your chain's blob and how often the batcher is doing its thing. This way, you can stay on track with your budget! (thedefiant.io).

Latency: “soft confirmation” vs settlement finality

Users get super fast “sequencer confirmations,” and you have the power to decide how frequently L1 anchoring takes place. So, when it comes to Nitro-based stacks, the standard max delay for posting a batch is usually set at 1 hour. However, most teams working in production tend to opt for a much shorter window--like around 5 to 15 minutes. This helps them find the sweet spot between keeping costs down and ensuring a smooth user experience. Just a quick reminder: there’s an assertion cadence to keep in mind, plus a fraud-proof window that typically lasts around 7 days when it comes to optimistic rollups. (docs.arbitrum.io).

Here are some tuning tips you can try out this week:

Try setting the batcher max delay to somewhere between 5 to 15 minutes. That should work pretty well! This really helps make sure the user experience stays seamless, all while keeping the compression effective. Hey, when things get busy, it's a good idea to increase those batch size limits. That way, you'll make the most out of your blobs!

Keep an eye on “bytes per L2 transaction” and connect it to blob gas. This way, you can predict fee ranges about an hour ahead of time.

How to break past 4844 ceilings

Alt-DA: So, when you throw something up on Celestia or EigenDA, you're kind of splitting your throughput away from Ethereum's blob lane. It's like carving out your own space! So, at the moment, Celestia's mainnet is capable of managing some hefty data squares--think about an 8 MiB max square. Plus, it scales really nicely with DAS, which is pretty cool! On the bright side, EigenDA has been smashing some pretty impressive MB/s targets on the mainnet! Hey, before you dive in, it’s a good idea to double-check those SLAs, costs, and security details. Better to be safe than sorry! (docs.celestia.org).
Shared/Decentralized Sequencers: Thanks to Espresso’s HotShot confirmation network, rollups can enjoy super-fast, BFT-backed pre-confirmations that work across different chains. It's a game-changer! This really makes things easier for users and smooths out cross-rollup bridging, even if L1 settlement is a bit slow. On top of that, Astria offers this awesome shared sequencing layer that only takes about a second to operate. It teams up seamlessly with Celestia DA, making those modular rollups run smoothly. (docs.espressosys.com).

Sidechains: fast and cheap, but with different trust

Sidechains, such as Polygon PoS, have their own way of reaching consensus. So, what this really means is that they don’t have to deal with the restrictions that come with Ethereum’s blob limits, which is awesome because it keeps the fees super low! Just a heads up, though--how secure and final everything is really hinges on the validator set and the tools backing the sidechain.

Block time and fees: When it comes to Polygon PoS, it's known for being super speedy, typically hitting around 2 seconds. Super low fees and lightning-fast 1-second transactions! When you’re checking gas prices, you might notice they're often expressed in just tiny fractions of a cent for normal transactions. Just a heads up, though: the exact dollar amount you see will really depend on how much the token is currently priced at. Feel free to take a look at this: Polygon Gas Tracker. It's pretty handy!
Operational risk: Just a heads up--if the consensus on a sidechain starts to slow down or there's a hold-up in finality, it can really throw a wrench in the user experience. This can be pretty frustrating for users, even if blocks are still getting churned out. So, back in September 2025, Proof of Stake (PoS) was experiencing some hiccups with finality, taking around 10 to 15 minutes. It was kind of frustrating because, at the same time, blocks were still being generated and rolling in. You’ll definitely want to keep this in mind when you're planning out your operations. If you're looking for more info, check this out: The Block. It's got all the details you need!

When to Pick a Sidechain:

Hey there! So, if you're diving into consumer apps and really need to keep your costs down while also ensuring that gas sponsorship is a big part of the user experience, sidechains could be a great option for you.
Just embrace the chain’s own way of doing things and roll with its trust model. You're cool with using bridges and feel good about the fact that they don't automatically offer the same security guarantees as Ethereum L1.

Purpose‑built real‑time settlement L1s: speed and price at base layer

These platforms are designed for fast results and high efficiency, and the best part is, they don’t require an L2 hop to get there. They really shine in situations where low latency is key--think trading, messaging, gaming, and even micropayments.

Hey, just a heads up--every platform has its own little quirks and tricks that make it unique. So, make sure to take some time to figure out what really clicks for each one! You'll thank yourself later!

Solana: So, the base fee is set at 5,000 lamports, which is basically just 0. For every transaction, it’s set at 0.000005 SOL. Even when things get really busy, the standard priority fees usually stay under ten cents. When it comes to commitment levels, transactions are processed super quickly--usually in under a second. You can expect them to be confirmed in about 1 to 2 seconds, and finalized in roughly 10 to 20 seconds. Just keep in mind, though, that these times can change a bit depending on how the network is feeling at the moment. Also, they've just started rolling out Firedancer, the new C++ validator client. It's designed to ramp up throughput and add some variety to the client options we have. (solana.com).
NEAR: By May 2025, the mainnet is cruising with 600 ms blocks and hitting around 1. In Nightshade 2, you can expect finality in just 2 seconds, thanks to something called “optimistic blocks." It’s pretty impressive how quickly it gets things wrapped up!

0. Wow, that's seriously impressive! Finality on a public chain like that is no small feat. Just check out this link for more details: pages.near.org.

Avalanche: Get ready for super quick finality--it's around 0 seconds! So, from what I gathered in the builder docs, it looks like Avalanche L1s can handle transactions in just 8 seconds. Pretty cool, right? They recently raised the gas targets on the C-Chain, and that’s really helped boost the throughput capacity. (build.avax.network).
XRPL: If you’re looking to make a standard transaction, you’ll only need to pay a minimum fee of 10 drops, which is basically 0. So, XRP transactions are pretty quick, with ledgers typically closing every 3 to 5 seconds. How cool is that? This setup is really great for handling payment transactions! (xrpl.org).
Stellar: So, on Stellar, ledgers wrap up about every 5 seconds. Pretty quick, right? When it comes to Soroban smart-contract fees, they’re designed to be resource-metered. This means there are clear schedules for CPU, memory, and disk usage. It’s a handy way to keep track of your gas budgets without any guesswork! (developers.stellar.org).
Hedera: The fees are in USD and you pay them using HBAR, so it’s really easy to keep track of your budget. Hey, just wanted to give you a quick heads up! Hedera is planning to raise the fee for the ConsensusSubmitMessage from its current rate of $0. 0001 to $0. Just a heads up--starting in January 2026, that feature will be changing, so be sure to keep that in mind if you count on it! (hedera.com).

What to Keep in Mind:

So, if we’re talking about those little transactions you see all the time, like ads, tips, and in-game events, the cost on these L1s is typically super low--often less than a cent! Sometimes, it can even dip below that! And the best part? You’ll see those transactions wrapped up in just a few seconds or even quicker. Pretty neat, right? Forget about stressing over batchers or blob prices. What's really important is keeping your validator and client running smoothly and figuring out your priority-fee policies. That's where your attention should be! (solana.com).

Concrete comparisons you can plug into planning

Here are some quick and easy models you can customize to suit your needs. Just think of them as a starting point! Don't forget to do your own load tests to ensure everything's running smoothly! It's always better to double-check.

Payments app: We're processing a whopping 1 million simple transfers daily, all while making sure your experience is as smooth as possible!

Solana: The base fee is actually zero! Can you believe that? You'll earn 000005 SOL for every transaction you make. With SOL sitting at about $100, that breaks down to roughly $0. 0005 per transaction. If you’re planning on doing around 1 million transfers, you’re probably looking at about $500 in fees, give or take. That’s not even including any optional priority fees, which are usually pretty small if you choose to go that route! Usually, you can count on getting a final answer in under 20 seconds, and those confirmations? They usually come through in less than a second! (solana.com). So, when we talk about the OP-Stack rollup, let's say each transaction is roughly 10 bytes once it's been squished down into blobs. Just keep in mind that this can change depending on the chain we're looking at! Blob lane prices are actually quite affordable, so most user fees usually end up being below zero. After Dencun, it's going to be $01 for each transaction. If you're looking to break it down, it's about $0 on average. For 1 million transfers, you should probably set aside around $3,000. But hey, if you get creative with compression and batching, you might be able to cut that down quite a bit! Just a heads up: the settlement and withdrawal processes will still follow the timing of Layer 1. (thedefiant.io).

2) Real-time exchange: sub-second state changes and cross-market risk

Hey, so platforms like NEAR and Avalanche are pretty impressive. They can wrap up transactions in only 1 to 2 seconds! Plus, they’re designed to handle a ton of transactions straight from the base layer. Pretty cool, right? This means you can say goodbye to those frustrating L2/L1 anchoring delays! This is super handy when you need your product to communicate that it gets things done in just 2 seconds! If you’re curious and want to dive deeper into it, check it out here. You’ll find all the juicy details!

So, when you're using a rollup, you might notice that the sequencer gives you quick replies, which is pretty sweet. But just a heads up: your cross-domain safety--things like bridges and liquidations--still needs to stick to the L1 batch and settlement cycles. It’s important to keep that in mind! You might want to check out a shared sequencer like Espresso. It could help speed up those cross-rollup confirmations while you're dealing with that settlement lag. It’s definitely something to consider! If you’re looking for more details, you can check it out here.

3) Compliance-Sensitive Integrations

Hey, have you heard about Hedera? They've got this awesome feature with their USD-fixed fees that really simplifies budgeting and procurement. You know, like knowing exactly what you're spending per API call. Plus, the fact that you can expect finality within seconds makes going through reconciliations a breeze! It’s such a game-changer. Take a look at this: (hedera.com). You might find it pretty interesting!

Why rollups still win for many enterprise builds

Ethereum Security and Composability: By using Ethereum, you're really benefiting from its strong validator system and economic security. Plus, you're just “a bridge away” from accessing tons of on-chain liquidity and some of the best tools available!
Horizontal scale: You can start multiple rollups tailored to their specific areas, and they’ll all work together seamlessly while remaining EVM-compatible. We're tackling those pesky data availability issues with PeerDAS (EIP-7594) and looking ahead to some upcoming blob-capacity upgrades. Take a look at this link: eips.ethereum.org. You might find it pretty interesting!
Pre-confirmations are becoming a reality: Thanks to shared and decentralized sequencers, the time it takes for users to see their transactions is shrinking to just a matter of seconds. This makes handling cross-rollup intents a lot safer and smoother! Espresso’s HotShot is super quick at confirming transactions, taking just a few seconds. Plus, it’s designed to easily scale up with a ton of nodes. Learn more: (docs.espressosys.com).

Here's a little something to remember: when it comes to rollup throughput nowadays, it's all about the bytes. It's not just about the "TPS" you see on a spec sheet anymore. "Alright, so when it comes to your engineering work, you really want to focus on getting those compression techniques down, figuring out the best ways to batch things, and picking the right data architecture. That's where you'll make the biggest impact!"

Emerging best practices to push throughput and drop fees

For Rollups:

Adjust batchers with purpose: Try setting a maximum delay of around 5 to 15 minutes. Also, tweak the batch size thresholds to match your daily traffic patterns. This way, you can maintain a high level of compression without delaying your posts. Hey, if you’re looking for more info, you can find all the details right here. Hope that helps!
Aggressive compression: Feel free to play around with the Brotli settings on your real calldata. Don’t hold back--this is where you can really see what works best! Make sure to keep an eye on the "compressed bytes per transaction" and do everything you can to lower that number continuously. Hey! I found some interesting research that might help you out. Check it out here.
Give Alt-DA a shot: If you're working with a bunch of big fixed-rate data, like logs or receipts, it might be worth trying out Celestia. Just take it for a test run and see how it goes! If you're looking to boost your overall MB/s, EigenDA might just be the perfect solution for you. Hey, just double-check the pricing and see how the failure modes compare to Ethereum's data availability. Learn more here..
Ship shared sequencing: If you’re looking for faster confirmations, go ahead and reach out to Espresso or Astria. They can get you set up in just seconds, making your cross-chain experience way smoother! Hey, if you're curious about the architecture, you can check out this link for more details: Find out more about the architecture!. It's a great resource!
Planning for a smooth settlement process: If being able to withdraw funds is a big deal for you, it’s a good idea to take into account the 7-day dispute window for those optimistic scenarios. And if you're going the ZK route, don't forget about the time it takes to verify proof! Just a quick note: make sure your bridging UX makes it easy to see the difference between “sequencer-confirmed” and “L1-final.” It’s super important for clarity! Sure! If you want all the info, just click here. You'll find everything you need!

For Sidechains:

Operational SLOs: Put together some handy runbooks for managing issues like finality delays and pesky RPC stability problems. You should also consider how the app's user experience (like managing balances and placing orders) can handle those pesky finality stalls that might drag on for a few minutes. It's all about making sure everything runs smoothly, even when things get a bit backed up! (theblock.co). Make sure you're keeping tabs on the health of your validators and the versions of the clients, just like you would for any important infrastructure.

For Real-Time L1s:

Price Stability: If you're looking at your profit and loss statements in dollars, it could be a smart move to explore Hedera’s USD-fixed fees. They can help you dodge those annoying fee swings that can throw everything off balance. If that’s not the case, don’t forget to keep an eye on how sensitive your unit economics are to shifts in token prices--take SOL as an example. (hedera.com).
Throughput Guardrails: Hey, just a heads up--don’t get too caught up in those “TPS” figures. It’s really essential to get into the nitty-gritty details, like block and slot timing, how priority fees work, and what finality actually means for your specific chain and client version. Understanding these things can make a huge difference! (helius.dev).

Deep dive: numbers behind the choices

Ethereum DA math today: So, with a slot that lasts 12 seconds, you’re looking to hit around 3 blobs (you can go up to 6 if you really want). Each blob has a capacity of about 128 KiB. So, you've got a budget of about 32 to 64 KiB/s. So, if you're dealing with compressed L2 transactions that typically use around 60 to 120 bytes of blob data, you can expect to see a range of hundreds to maybe even a thousand transactions per second (TPS) happening across all rollups in the system. It's pretty interesting how that all adds up! On top of that, there are cool improvements like PeerDAS that really help boost blob throughput. They do this by allowing sampling instead of forcing full downloads, which means the nodes don’t get overwhelmed. Pretty neat, right? (eips.ethereum.org).
Avalanche's Take on TTF: If you dive into their documentation, you'll notice they really emphasize time-to-finality (TTF) as a way better measure than just looking at those raw transactions per second (TPS) numbers. It's an interesting perspective that highlights the importance of how quickly a transaction is fully completed, rather than just how many can be rushed through. The platform is designed to wrap things up in less than a second, all while handling thousands of transactions per second. Plus, with cool upgrades like Octane, they can really boost the C-Chain gas targets. This is really important because having that finality is what brings businesses that nice feeling of certainty when it comes to the user experience. (build.avax.network).
Solana fee quick overview: The starting fee is a cool 0. So, when it comes to 000005 SOL, there's also this optional priority fee you can add, which really helps keep costs for regular actions super predictable--like, we're talking just a few cents! You still get to decide how committed you want to be with the different levels (processed, confirmed, and finalized). This way, you can set up those ideal user experience moments just the way you want them! (solana.com).
XRPL and Stellar fees/transaction finality: When it comes to XRPL, you’re looking at a minimum fee of just 10 drops, which is super low! Plus, ledger closures happen in roughly 3-5 seconds. That makes it an awesome choice for payment systems! On the plus side, Stellar is pretty quick too--it wraps up ledgers in about 5 seconds! Plus, they've rolled out fee schedules for Soroban, which is super handy because it lets you simulate costs accurately when you're working with smart contract calls. (xrpl.org).
Hedera’s budgeting perk: Since the fees are set in USD, keeping track of spending and the costs for each API is super easy. Hey! Just a heads up to keep an eye on the price change for ConsensusSubmitMessage that’s set to happen in 2026. (hedera.com).

When to choose what: a quick playbook

If you’re considering a rollup--maybe even creating your own app-chain rollup--take a moment to think about these factors first:

So, you want that sweet EVM compatibility along with the solid security that Ethereum offers. Plus, you’re planning to roll out a whole bunch of stuff--think payments, loyalty programs, gaming, and more--all while using the same toolkit. That sounds like a smart move!

You're totally fine with a few bumps in the road when it comes to settlements--like waiting a few minutes for anchoring or even days for that optimistic finality. Plus, you're all in on crafting a cool pre-confirmation experience for your users. So, you're looking to leverage Alt-DA and shared sequencers to create a user experience that's pretty close to real-time, without straying from Ethereum's core principles. Sounds like a solid plan! If you want to dive deeper into the details, just click here. You'll find everything you need!

Choose a sidechain if:

Your main focus is to keep fees as low as possible and make sure block times are quick. Sure, that might mean you have to navigate some different risks when it comes to consensus and trust, but that’s a trade-off you’re willing to accept. It’s a good idea to have some backup plans in place in case there are any delays in getting things finalized or if you run into any issues with RPC. Better safe than sorry, right? (theblock.co).

If you're looking for something that's built for real-time L1, definitely go for it!

You'll get super quick confirmations--like, we're talking less than a second to just a few seconds--along with really tiny fees, sometimes just a few cents or even less. This really matters when it comes to things like high-frequency trading, sending payments in real time, or messaging. If you're not set on using Ethereum for your MVP, there are some great alternatives out there! Take a look at Solana, NEAR, Avalanche, XRPL, Stellar, and Hedera. Each of these platforms has its own unique way of handling regulations and operations, so there's plenty to explore! Be sure to give them a spin with an actual load! (solana.com).

Implementation checklist (what we advise clients at 7Block Labs)

What’s “real-time”?: First, figure out how committed you want to be--are you going for soft or final? Then, determine the latency you’re shooting for, measured in seconds. Just keep this in mind when you're working on your user experience and service level agreements, okay? It really helps to align everything! If you want to dive deeper into it, you can check it out here.
Cost guardrails: When you're working with rollups, don’t forget to monitor the “compressed bytes per transaction,” the blob base fee, and the batcher delay. It’s all about keeping those costs in check! When you're looking at Layer 1s, keep an eye on the token price and how it plays off the base and priority fee curves. Or if you’re diving into Hedera, you can just stick with those fixed USD schedules. If you're looking for more information, you can check it out here.
DA strategy: Kick things off with Ethereum blobs. If you hit any limits on DA or you’re looking for stable pricing when you're ramping up bandwidth, it might be worth considering a shift to Celestia/EigenDA down the line. If you want to dive deeper into it, check it out here!
Pre-confirmations: If you want to enhance your bridging experience, think about adding Espresso or Astria. They can really help with getting that cross-rollup confidence in just seconds! If you want to dive deeper into this topic, you can check out more details here. It's got a bunch of useful info!
Incident playbooks: When you're diving into sidechains, don’t forget to include stuff about finality lag and those pesky RPC brownouts in your runbooks. It's super important to be prepared! Hey, when you're working on rollups, make sure to remember to include those L1 reorg resistance settings and the forced-inclusion paths! They’re super important. Check out all the details here. You'll find everything you need to know!

Bottom line

Rollups have really become quite affordable lately, and they can scale horizontally, which is a big plus. Plus, there’s been some cool development on the tooling front that makes them feel nearly real-time. That’s super useful when you’re trying to stay in sync with Ethereum! That being said, their long-term performance really depends on how many bytes are being processed on Ethereum at this moment. Basically, they're keeping pace with the Layer 1 settlement speed. (eips.ethereum.org). On the bright side, sidechains and specialized real-time Layer 1s really shine when it comes to speed and cost-effectiveness right from the start. This is awesome for anyone dealing with high-volume transactions that need to happen fast. Just keep in mind that you’ll want to be comfortable with how their security and operations work. (solana.com).

Just give us a shout with your desired SLA. For instance, you might say something like, “I want users to see money show up in under 2 seconds,” and “we can’t go over $0 on this.” So, if we're looking at $0.002 for each transaction and you’re doing around 10 million transactions every day, we can definitely use that info to build a solid architecture for you. Let's go ahead and run some load tests to compare everything. That way, we can make sure we meet both the throughput and cost targets before you decide to commit.
