For most permissionless modular rollups, Celestia is the safest starting point because data-availability sampling (DAS), erasure coding and namespaced Merkle trees let light clients verify that data is available without downloading an entire block. EigenDA is a better fit when your team accepts an EigenLayer AVS model built around opt-in operators, restaking and quorum attestations in exchange for very high service throughput. Avail is worth evaluating when its expandable-blockspace roadmap and ecosystem integrations match your design, but its current production capacity, fees and bridge maturity need deployment-specific verification.
The right choice is not determined by a headline megabytes-per-second figure. Compare the verification model, retrieval guarantees, workload capacity, finality and bridge path, fees, integrations and the operational responsibilities your team can actually run.
What a data-availability layer does
A rollup publishes transaction data somewhere so anyone who needs to reconstruct state can obtain it. A data-availability (DA) layer answers the narrower but essential question: has the block’s data been published and can it be downloaded? If data is withheld, users may be unable to verify the rollup’s state transition, recover from an operator failure or challenge an invalid claim.
DA is separate from execution and settlement. A rollup can execute transactions with its own virtual machine, publish the resulting data to a DA network, and settle proofs or disputes on another chain. That separation lets a team choose a DA service for its publication and retrieval properties rather than accepting the limits of the settlement chain.
#1 Best Overall
Before comparing networks, specify four workload facts:
- Average and peak bytes published per block or batch.
- Burst rate during launches, mints, games or other high-demand periods.
- How long data must remain retrievable and who is responsible for retention.
- The maximum acceptable time from publication to usable finality.
Without those numbers, a capacity comparison is only a marketing exercise.

Celestia: public-chain verification with DAS
How availability is verified
Celestia separates consensus and data availability from execution and settlement. It uses erasure coding to add recoverable information to block data. Light clients then perform data-availability sampling: they request small, randomly selected portions of a block rather than downloading the entire block. Repeated successful samples provide a probabilistic assurance that the complete block can be reconstructed.
Recommended Free Tools
Namespaced Merkle trees (NMTs) organize data by application namespace. A rollup can request proofs and retrieve the portions belonging to its namespace instead of scanning unrelated applications’ data. That is useful when several rollups share the same DA chain and each needs a bounded retrieval path.
What the trust model assumes
DAS is not a promise that every failure disappears. Celestia’s documented assumptions include at least one honest bridge node and protection against eclipse attacks. Your light clients must be able to reach an honest view of the network; a node isolated by an attacker can be misled even when the underlying chain is functioning correctly. Document how bridge nodes are operated, how peers are discovered and how clients react when sampling fails.
Where Celestia fits best
Celestia is the natural default for a modular rollup that wants a permissionless DA blockchain and client-side availability checks. The rollup can choose its own execution and settlement layers while publishing transaction data to Celestia. Namespace retrieval also gives application operators a clear way to separate their data from other users’ blobs.
Fees and prioritization
Celestia uses PayForBlobs transactions. The charge combines a flat transaction component with a variable component based on blob size. Transactions offering higher gas prices are prioritized. A budget therefore depends on both the number and size of blobs and the prevailing gas market; a historical comparison is not a valid current quote.

Celestia documents separate light, bridge and consensus roles. The following starting points were published on October 16, 2026; they are sizing guidance, not a guarantee of performance under your workload.
| Role | Published starting hardware | Typical responsibility |
|---|---|---|
| Light node | 500 MB RAM and 20 GB SSD | Sample block data and verify availability without storing the full chain |
| Bridge node | 64 GB RAM, 32 cores and 2 TB NVMe | Provide a bridge between consensus information and light-client users |
| Archival consensus node | 64 GB RAM, 32 cores and 16 TB NVMe | Maintain the full consensus history and serve archival requirements |
Storage growth, retention policy, geographic redundancy and traffic from your own rollup can push requirements above these starting values. Test the complete publication and recovery path rather than sizing only the submission client.
EigenDA: an EigenLayer AVS/DAC service
How its security differs
EigenDA is described as an Actively Validated Service (AVS) in the EigenLayer model, not as the same kind of publicly verified DA blockchain as Celestia or Avail. Operators opt in, run the service software and accept on-chain slashing conditions in exchange for payments. Restaked collateral supplies economic security, while contracts define payment and penalty behavior.
In this design, a certificate or quorum attestation says that the participating operators accepted responsibility for the data. It does not automatically provide the same verification properties as DAS. Your integration must state which operators form the quorum, how much collateral backs an attestation, what constitutes attributable withholding, and how a user detects and challenges a failure.
The Tool Desk

The AVS approach can provide a service optimized for very high throughput and can be attractive to teams already using EigenLayer components. An Avail-authored comparison cites 100 MB/s for EigenDA V2. That is a dated, project-published figure rather than an independent, apples-to-apples benchmark, so load-test your exact blob sizes, concurrency and retrieval pattern.
Operational responsibilities
A rollup using EigenDA must account for more than a client library. Review operator enrollment and churn, quorum thresholds, restaked asset composition, slashing implementation, payment contracts, key management and the process for reconstructing data when one or more operators are unavailable. Clarify whether your users can retrieve data directly, through an aggregator, or only through a designated service path.
Ask for an explicit failure runbook: what happens when an operator withholds data, when a quorum is not reached, when an attestation arrives late, and when the service or its bridge is unreachable. If the answer depends on a separate DAC or committee, include that component in the trust analysis.
Avail: expandable blockspace with deployment questions
Capacity positioning
Avail presents itself as a blockchain-based DA layer with expandable blockspace. Its cited comparison reports 4 MB per block for Avail, 8 MB per block for Celestia and 100 MB/s for EigenDA V2, while describing a roadmap toward 10 GB blocks. These figures were published by Avail, are tied to the cited update and should be treated as orientation rather than neutral benchmarking.
A roadmap target is not the same as current production capacity. Verify the live block limit, sustained throughput, fee schedule, retention behavior and performance during bursts before making a capacity commitment.
Verification and bridge review
Avail’s blockchain-based design needs a deployment-specific review of its current light-client and bridge model. Confirm how a rollup verifies availability, obtains proofs, handles namespace or application filtering, and recovers when a bridge or relayer is offline. Also verify bridge maturity for the exact execution and settlement networks you plan to use; an integration shown in documentation may not cover your target geography or production version.
When Avail is compelling
Avail deserves priority in a shortlist when its ecosystem integrations, planned blockspace expansion or settlement connectivity remove a concrete constraint for your project. Select it because those capabilities are available and tested for your launch, not solely because a future 10 GB target sounds larger than today’s block sizes.
Side-by-side comparison
| Decision axis | Celestia | EigenDA | Avail |
|---|---|---|---|
| Verification | DAS with erasure coding and NMT proofs for application namespaces | AVS/DAC operator attestations backed by opt-in restaking, quorum rules and slashing contracts | Blockchain-based DA; validate the current light-client and bridge implementation |
| Published capacity evidence | 8 MB per block in Avail’s cited comparison; limits can change | 100 MB/s for EigenDA V2 in the same dated comparison | 4 MB per block in that comparison; 10 GB is a stated roadmap direction |
| Fee model | PayForBlobs: flat transaction fee plus blob-size fee; higher gas prices receive priority | Current service and commercial terms must be obtained for the deployment | Current fee schedule must be obtained; no stable cross-network figure is established here |
| Operator burden | Choose among light, bridge and consensus roles; published hardware guidance exists | Run or depend on AVS operators, software, restaking and slashing processes | Verify current node, bridge, retention and relayer requirements |
| Most defensible starting use | Permissionless modular rollup requiring DAS and namespace retrieval | EigenLayer-aligned project that values service throughput and accepts AVS assumptions | Project whose tested integrations and expansion roadmap solve a specific capacity or connectivity need |
How to compare throughput without being misled
“MB per block” and “MB/s” describe different things. Block capacity depends on block interval, while a service-rate claim describes a rate that may assume a particular batch size, operator set and network condition. Convert every claim into the units your rollup uses: bytes per batch, batches per minute, peak burst duration and bytes that must be retrieved by a new node.
Run the same test plan against each candidate:
- Submit representative small, medium and maximum-size blobs.
- Replay your expected peak burst, including concurrent rollups if you share infrastructure.
- Measure acknowledgment time, inclusion, finality and time until an independent client can retrieve the data.
- Force operator, bridge, relayer and RPC failures, then measure reconstruction and recovery.
- Record CPU, memory, disk I/O, bandwidth and storage growth for the retention period you require.
No independent, apples-to-apples benchmark establishes a universal winner. Treat the cited figures as starting hypotheses and publish your own acceptance thresholds.
Fees, finality and bridge path
Build a live cost model
For Celestia, estimate the flat PayForBlobs transaction component, the blob-size component and gas-price volatility. For EigenDA and Avail, obtain current service or network terms and include operator, relayer, bridge and RPC costs. Add the cost of storing a second copy of data if your recovery policy requires it.
Calculate cost per published byte under normal and peak conditions. A low nominal fee can become expensive if your rollup must over-provision bandwidth, retain data indefinitely or pay for a separate retrieval service.
Trace the complete finality path
Draw the sequence from batch creation to DA acceptance, DA finality, bridge observation, execution-layer confirmation and settlement. Identify which step users rely on when withdrawing, proving a state transition or rebuilding a node. A DA network with fast publication but a slow or immature bridge may deliver a worse user experience than a slower network with a well-tested path.

- Define the workload. Write down average and peak data volume, burst length, block or batch cadence, retention period and retrieval SLA.
- Price current usage. Use live network quotes and current service terms. Do not put the dated 4 MB, 8 MB or 100 MB/s comparison figures into a budget.
- Test submission and retrieval. Use the exact blob format, namespace behavior, bridge and RPC path planned for production, from the regions where your operators and users will run.
- Document the security assumption. For Celestia, include DAS, at least one honest bridge node and eclipse resistance. For EigenDA, specify operator quorum, restaked collateral, slashing and withholding challenges. For Avail, document the current light-client, bridge and relayer model.
- Measure end-to-end finality. Record publication-to-finality latency and data reconstruction time under normal load and during injected failures.
- Recheck before launch. Confirm software versions, block limits, fees, bridge integrations, operator terms and retention behavior immediately before production deployment.
Failure modes and recovery questions
Data is accepted but cannot be retrieved
Check whether the problem is a namespace or proof mismatch, an unavailable bridge, an RPC outage or a retention-policy gap. Keep an independently tested retrieval path and alert when sampled data cannot be reconstructed within the SLA.
Best Value
Sampling or attestations do not reach the required threshold
For Celestia, inspect peer connectivity, eclipse defenses and bridge-node health. For EigenDA, inspect operator quorum, signer availability and attestation timing. Do not treat a timeout as proof that data was unavailable; preserve logs and follow the network’s documented challenge or retry procedure.
Capacity is exhausted during a burst
Define back-pressure behavior before launch. Decide whether the sequencer queues batches, raises fees, reduces batch size or pauses publication. Test how delayed DA affects user-facing confirmations and settlement deadlines.
A bridge or integration changes
Pin compatible software versions, monitor deprecations and maintain a rollback or migration plan. Revalidate the exact execution and settlement networks after any bridge upgrade; an otherwise healthy DA layer cannot compensate for an incompatible adapter.

Which network should you choose?
Choose Celestia when verification independence is the priority
Select Celestia when your rollup wants a public DA blockchain, light clients that can sample availability, and namespace-level retrieval while execution and settlement remain modular. It is the strongest default when you can operate or contract for the documented node roles and satisfy the honest-bridge and anti-eclipse assumptions.
Choose EigenDA when EigenLayer alignment outweighs public-chain simplicity
Select EigenDA when your team is prepared to reason about AVS operators, restaking, quorum certificates and slashing, and when tested service throughput is more important than using the same light-client verification model as a DA blockchain. Put the operator and withholding-failure runbooks in the architecture document, not in an informal assumption.
Choose Avail when its tested roadmap and integrations solve a specific constraint
Select Avail when current mainnet behavior, bridge support and ecosystem integrations meet your launch requirements and its expansion plan matters to your growth trajectory. Treat the 10 GB direction as a roadmap consideration until the capacity is available, measured and supported in your target environment.
Production-readiness checklist
- Workload envelope approved by the rollup, infrastructure and security teams.
- Current fee and capacity data captured for the intended launch window.
- Independent publication and retrieval tests completed from more than one region.
- Finality and bridge dependencies mapped to user actions and settlement deadlines.
- Security assumptions, quorum rules and challenge procedures written down.
- Node, operator, relayer, monitoring, key-management and storage ownership assigned.
- Failure drills completed for unavailable data, delayed attestations, bridge outages and capacity bursts.
- Software versions and integration compatibility rechecked immediately before launch.
The decision is ultimately an architecture choice, not a leaderboard choice. Start with the verification guarantees your users need, prove the full retrieval and finality path under your workload, and only then optimize for capacity or cost.
