Methodology and scoring
We scored each data availability layer across 8 weighted criteria reflecting what matters in 2026: blob throughput in MB/sec (15%), rollup adoption count (15%), security model strength (15%), ecosystem integration depth (10%), token economics for native tokens (10%), data sampling architecture quality (10%), settlement assurances (10%) and 2026 product roadmap (15%).
Data sources: blockspace dashboards (Modular Cloud, blockworks DA tracking), protocol-published throughput metrics, rollup deployment count, our own evaluation of data sampling guarantees plus security assumptions. We exclude DA networks with under $50M TVL because below that threshold ecosystem credibility plus security guarantees are too thin for meaningful evaluation.
Critical context: DA category emerged through 2023-2026 as modular blockchain thesis materialized into production rollup deployments. Ethereum's blob fees (EIP-4844) created native Ethereum DA but at higher cost than alt-DA networks. Celestia pioneered pure DA at meaningful scale. EigenDA leveraged EigenLayer restaking for differentiated security. Avail competed on Ethereum-aligned validity proofs. Near DA, 0G Labs and Walrus serve specific ecosystem niches. Selection requires alignment with rollup architecture plus security preferences.
Scoring is 0-10 per criterion with weighted average producing the final score. Score range in this ranking: 6.4 to 8.8. We don't include DA networks below 6.0 because alternatives outperform on most criteria.

Celestia
Pure data availability pioneer with 100MB+ daily blob throughput plus $TIA token economics
Score
8.8/10
Celestia is the category-defining pure DA layer with mainnet launch October 2023 plus $1B+ TVL by early 2026. The architecture uses data availability sampling (DAS) enabling light clients to verify data availability without downloading full blocks creating fundamentally different scalability properties than Ethereum's monolithic L1. TIA token serves as gas plus staking with significant validator decentralization. Rollup adoption crossed 50+ chains including Manta, Eclipse, Movement plus countless smaller deployments. Recent Lemongrass upgrade increased throughput materially. The honest weakness: Cosmos-based architecture creates Ethereum-alignment friction with bridges plus settlement separated from Ethereum L1. Token enable schedule pressure in 2024-2025 created sustained TIA price decline despite throughput growth. For pure modular DA at scale, Celestia is the structural default. The first-mover advantage plus 50+ rollup deployments demonstrated genuine adoption.
Key strengths
First production DA layer with 50+ rollup deployments
Data availability sampling enables light-client verification at scale
100MB+ daily blob throughput demonstrated
TIA token with significant validator decentralization
Honest weakness
Cosmos-based architecture creates Ethereum-alignment friction plus token enable pressure created sustained TIA price decline
Who it's for
Modular rollup builders wanting battle-tested DA, TIA holders, Cosmos ecosystem participants, sovereign rollup operators
EigenLayer-secured DA with restaked ETH security plus Ethereum-native settlement alignment
Score
8.4/10
EigenDA launched April 2024 as one of EigenLayer's flagship Actively Validated Services (AVS) leveraging restaked ETH for DA security. The architecture differentiates from Celestia through Ethereum-aligned security model meaning DA security inherits from Ethereum staking via restaking. Backed by major rollup deployments including Mantle, Layer N plus growing list of L2s wanting Ethereum-aligned DA cheaper than Ethereum blob space. The honest weakness: shorter operational track record than Celestia plus EigenLayer slashing mechanics still maturing creating untested security guarantees in adverse scenarios. Throughput claims have been validated in testing but production-scale demonstrated at smaller scale than Celestia. For Ethereum-aligned rollups wanting restaking-secured DA, EigenDA is the structural default. For sovereign rollup architecture plus battle-tested production scale, Celestia leads.
Key strengths
EigenLayer restaking provides Ethereum-aligned security model
Major rollup deployments including Mantle plus Layer N
Ethereum-native settlement alignment vs Cosmos-based alternatives
Growing throughput with technical roadmap toward 100MB+/sec
Honest weakness
Shorter operational track record than Celestia plus EigenLayer slashing mechanics still maturing creates untested guarantees
Polygon spinout with validity-proof DA architecture plus Ethereum-aligned settlement options
Score
7.8/10
Avail launched mainnet July 2024 after spinning out from Polygon as independent DA project with $AVAIL token. The architecture uses validity proofs (KZG commitments) plus data availability sampling creating mathematically guaranteed availability without trust assumptions. Avail Nexus aggregation layer enables cross-rollup messaging via shared DA. Rollup deployments include Sophon plus growing list of Avail-aligned L2s. The honest weakness: smaller adoption than Celestia plus shorter post-launch track record. AVAIL token economics under pressure post-launch creating governance uncertainty. For builders wanting validity-proof DA with Polygon ecosystem heritage, Avail leads. For pure scale plus first-mover ecosystem depth, Celestia dominates.
Key strengths
Validity-proof DA architecture with KZG commitments
Avail Nexus enables cross-rollup messaging via shared DA
Polygon ecosystem heritage plus engineering credentials
Ethereum-aligned settlement options
Honest weakness
Smaller adoption than Celestia plus AVAIL token economics under pressure post-launch creates governance uncertainty
Near Protocol's native data availability layer with chain abstraction plus Nightshade sharding
Score
7.2/10
Near DA leverages Near Protocol's native data availability layer (Nightshade sharding architecture) creating low-cost DA option for rollups wanting Near-aligned settlement plus data availability. Major deployments include Polygon CDK chains using Near DA for cost optimization. The honest weakness: Near ecosystem dependency means Near DA success tied to Near Protocol adoption plus governance decisions. Smaller standalone rollup adoption than Celestia or EigenDA outside Near-aligned chains. Cross-VM bridging creates architectural friction for Ethereum-aligned rollups. For builders wanting Near-aligned DA with chain abstraction integration, Near DA is differentiated. For Ethereum-aligned or pure modular DA, alternatives are structurally cleaner.
Key strengths
Native Near Protocol DA leveraging Nightshade sharding
Modular DA with AI-focused throughput targeting plus integrated storage capabilities
Score
7.0/10
0G Labs launched as AI-focused modular DA with throughput targeting AI workload requirements (large model checkpoints, training data, inference logs). Architecture combines DA with integrated storage layer creating hybrid positioning between pure DA and storage networks. The honest weakness: AI-focused positioning is structurally narrower than general-purpose DA reducing total addressable market. Newer launch means shorter operational track record vs Celestia plus EigenDA. Rollup deployments still nascent vs category leaders. For AI-specific application use cases requiring high-throughput data availability plus storage, 0G is differentiated. For general modular rollup DA, alternatives win on adoption plus track record.
Key strengths
AI-focused throughput targeting AI workload requirements
Integrated storage layer alongside DA creates hybrid positioning
Strong VC backing including Hack VC, Animoca plus others
Differentiated positioning vs general-purpose DA networks
Honest weakness
AI-focused positioning narrows TAM plus shorter track record than category leaders limits institutional credibility

#6
Walrus
Sui-native blob storage with data availability properties plus Walrus token economics
Score
6.6/10
Walrus launched as Sui-native blob storage protocol with data availability properties via erasure coding plus Sui's consensus security. Different architectural positioning than pure DA networks because Walrus optimizes for storage durability over pure DA throughput. WAL token launched 2024-2025 enabling storage payments plus governance. The honest weakness: storage-first positioning creates architectural mismatch for pure rollup DA use cases requiring rapid blob retrieval plus DA sampling. Sui ecosystem dependency limits multi-chain DA flexibility. Smaller rollup adoption than category leaders. For Sui-aligned storage plus DA, Walrus leads. For pure rollup DA with battle-tested architecture, alternatives across non-Sui ecosystems win.
Key strengths
Sui-native blob storage with erasure coding plus Sui consensus security
WAL token enables storage payment plus governance economics
Storage-first positioning differentiates from pure DA networks
Sui ecosystem alignment for Sui-deployed applications
Honest weakness
Storage-first positioning creates architectural mismatch for rollup DA use cases plus Sui ecosystem dependency limits multichain flexibility
Who it's for
Sui ecosystem builders, blob storage users, Sui-aligned rollups, storage-durability-focused applications
EthStorage extends Ethereum's EIP-4844 blob storage to longer-term retention via Ethereum-native L2 storage protocol. The architecture uses Ethereum security with extended blob retention beyond Ethereum's native 18-day blob expiration. Different positioning than pure DA networks because EthStorage optimizes for blob retention not throughput. The honest weakness: nascent ecosystem with smaller TVL plus rollup deployments lagging significantly behind category leaders. Storage-extension positioning is structurally narrow vs general DA networks. ETH-native security inherits Ethereum's strengths but also limitations. For Ethereum-native long-term blob storage use cases, EthStorage leads niche. For general rollup DA throughput, alternatives win on every dimension.
The data availability category in 2026 stratified clearly with Celestia dominant at production scale plus differentiated challengers competing on security model alignment, validity proofs, ecosystem fit plus specialized use cases. Celestia maintained category leadership with 50+ rollup deployments plus 100MB+ daily blob throughput. EigenDA captured Ethereum-aligned restaking-secured DA. Avail competed on validity-proof architecture. Near DA, 0G Labs, Walrus and EthStorage served specific ecosystem niches.
For rollup builders wanting DA exposure, the choice depends on settlement layer alignment plus security model preferences. Sovereign rollups default to Celestia for battle-tested production scale plus first-mover ecosystem. Ethereum-aligned rollups default to EigenDA for restaking-secured architecture. Validity-proof advocates default to Avail for mathematical availability guarantees. Polygon CDK plus Near-aligned chains default to Near DA. AI-specific applications default to 0G Labs. Sui ecosystem applications default to Walrus.
For investors wanting DA-layer exposure, TIA is the cleanest token-level proxy via Celestia's production scale plus first-mover advantage. EIGEN serves EigenDA exposure but spans full EigenLayer ecosystem. AVAIL underperformed materially post-launch despite technical merits. Token enable schedules created sustained pressure across the category. Most professional DA exposure comes from rollup-level participation rather than direct DA token holding.
The honest negatives worth flagging: Celestia Cosmos-based architecture creates Ethereum-alignment friction plus token enable pressure created sustained TIA price decline. EigenDA shorter operational track record plus EigenLayer slashing mechanics still maturing creates untested security guarantees. Avail smaller adoption than Celestia plus AVAIL token economics under pressure post-launch. Near DA ecosystem dependency creates concentration risk. 0G Labs AI-focused positioning narrows TAM. Walrus storage-first positioning creates rollup DA architectural mismatch. EthStorage nascent ecosystem with limited rollup deployment.
The TG3 client recommendation: sovereign rollup builders default to Celestia for production scale plus 50+ rollup ecosystem. Ethereum-aligned rollups default to EigenDA for restaking-secured DA. Validity-proof advocates default to Avail. Polygon CDK chains default to Near DA. AI applications default to 0G Labs. For diversified DA exposure, holding TIA captures category leadership while EIGEN provides EigenLayer ecosystem position. AVAIL exposure depends on token economics stabilization.
The big-picture point: data availability emerged as critical modular blockchain category in 2026 with Celestia demonstrating production scalability plus EigenDA establishing Ethereum-aligned alternative. The category broke past theoretical modular thesis into functional production deployments serving real rollup throughput requirements. Selection now requires alignment with rollup architecture plus security preferences rather than pure technical preference. Celestia plus EigenDA dominate top tier. Avail competes on validity-proof differentiation. Specialized networks serve narrower niches that justify their lower rankings. Pick based on rollup architecture alignment with your settlement layer plus security model preferences.
FAQ
What's the best data availability layer in 2026?
Celestia leads category with 50+ rollup deployments plus 100MB+ daily blob throughput. EigenDA leads Ethereum-aligned restaking-secured DA. Avail leads validity-proof DA with Polygon ecosystem heritage. Near DA leads Polygon CDK plus Near-aligned rollups. 0G Labs leads AI-focused DA. The right answer depends on use case: scale plus battle-tested adoption (Celestia), Ethereum-aligned security (EigenDA), validity proofs (Avail), Near-aligned chains (Near DA), AI workloads (0G Labs).
Should I use Celestia or EigenDA for my rollup?
Depends on security model alignment plus ecosystem fit. Celestia wins for sovereign-rollup architecture plus battle-tested production scale with 50+ rollups deployed. EigenDA wins for Ethereum-aligned security via restaked ETH plus tight EigenLayer integration. For sovereign rollups wanting independent DA: Celestia. For Ethereum-aligned rollups wanting restaking-secured DA: EigenDA. Both are credible production DA layers with strong technical foundations. Selection depends on your settlement layer preferences plus security model alignment.
What's the difference between data availability and storage?
DA guarantees data is published plus retrievable for short retention periods (typically blob lifecycle of 18 days for Ethereum, similar for Celestia). Storage networks like Filecoin or Walrus optimize for long-term durability with retention years or permanent. Pure DA networks (Celestia, EigenDA, Avail) optimize for throughput plus light-client verifiability over retention duration. Storage-with-DA-properties networks (Walrus, EthStorage, 0G Labs) span both categories with different trade-offs. Use cases drive selection: rollup operations need DA, application data archival needs storage.
Why do rollups use alt-DA instead of Ethereum blobs (EIP-4844)?
Cost. Ethereum blob fees via EIP-4844 are higher than alt-DA networks like Celestia or EigenDA at typical throughput levels. Major rollups including Manta, Mantle, plus others migrated from Ethereum DA to alt-DA for cost optimization seeing 5-10x cost reductions. Trade-off: Ethereum DA inherits full Ethereum security while alt-DA networks have separate trust assumptions. For high-throughput rollups: alt-DA economics dominate. For maximum security alignment with Ethereum: blob DA wins despite higher cost. The category fragmented along this cost-security trade-off axis.
How does data availability sampling (DAS) work?
DAS lets light clients verify data availability without downloading full blocks. Celestia plus Avail erasure-code blob data then have light clients sample random pieces to probabilistically verify the full data is available. If sampling succeeds with sufficient nodes, the network has high statistical confidence the data is available. The architecture enables DA networks to scale without forcing every node to store everything. EigenDA uses different mechanism with EigenLayer-secured availability checks. Pure DA networks like Celestia depend on DAS for fundamental scalability properties.
Why is Celestia ranked above EigenDA when EigenDA has Ethereum security?
Production track record plus rollup adoption. Celestia has 50+ rollup deployments since October 2023 mainnet plus battle-tested at production scale. EigenDA launched April 2024 with shorter operational history. EigenLayer slashing mechanics still maturing creates untested security guarantees in adverse scenarios. EigenDA may overtake Celestia long-term if Ethereum-aligned security advantage overcomes Celestia's ecosystem lead but currently Celestia's production scale plus 50+ rollups represents real composability impossible to replicate quickly.
How does Crawlux rank data availability layers?
We score 8 weighted criteria: blob throughput (15%), rollup adoption (15%), security model (15%), ecosystem integration (10%), token economics (10%), DA sampling architecture (10%), settlement assurances (10%) and 2026 product roadmap (15%). Data sources: blockspace dashboards (Modular Cloud, blockworks), protocol-published throughput metrics, rollup deployment counts, our own evaluation of DA sampling guarantees plus security assumptions. We exclude DA networks under $50M TVL because below that threshold ecosystem credibility is too thin.
What about DA layers not on this list?
Several smaller DA networks exist (Domicon, Espresso DA component, Arbitrum AnyTrust, plus others). We chose 7 representing different architectures (pure DA, restaking-secured AVS, validity-proof DA, native chain DA, AI-focused, storage-with-DA, Ethereum-extension) with sufficient adoption for meaningful evaluation. Specialty DA solutions like Arbitrum AnyTrust serve specific rollup ecosystems but lack standalone rollup adoption. Espresso operates as shared sequencer with DA component rather than standalone DA. Smaller pure-DA alternatives haven't achieved meaningful rollup deployment counts to warrant inclusion.
