In the modular blockchain revolution, data availability (DA) is the linchpin that enables secure, scalable rollups to thrive. As we move into 2025, the landscape is dominated by two powerhouses: Celestia and EigenLayer. Each brings unique innovations to the table, unlocking new possibilities for developers and investors who want to ride the next wave of decentralized infrastructure. Let’s break down how these DA leaders are shaping the future of modular rollups and what it means for the ecosystem.
Why Data Availability Matters for Modular Rollups
Rollups have become the go-to solution for scaling blockchains without sacrificing decentralization or security. By offloading execution from Layer 1 chains, rollups can process more transactions at lower costs. However, this model creates a new bottleneck: ensuring that transaction data is always available and verifiable. If data becomes unavailable or corrupted, users can’t reconstruct the state of the chain – opening up attack vectors and undermining trust.
This is where dedicated DA layers like Celestia and EigenLayer step in. They guarantee that anyone can access transaction data at any time, allowing light clients to independently verify rollup integrity without having to trust centralized actors or committees.
Celestia: Blobspace for Modular Rollups
Celestia, launched in late 2023, pioneered a modular approach by focusing solely on consensus and data availability – skipping execution entirely. This laser focus has paid off: as of November 2025, Celestia’s blobspace is actively used by over 30 rollups and modular applications.
Celestia’s core innovations include:
- Data Availability Sampling (DAS): Allows nodes to verify large blocks by checking only random samples rather than downloading everything. This dramatically reduces hardware requirements and enables true decentralization.
- Namespaced Merkle Trees (NMTs): Let each rollup isolate its own data within shared blocks, making retrieval fast and efficient without processing unrelated information.
- Permanent Blob Storage: Unlike Ethereum’s EIP-4844 blobs which expire after weeks, Celestia stores blobs permanently – giving developers long-term guarantees for their applications.
This architecture means that rollups simply post their compressed transaction blobs to Celestia and pay fees in TIA (currently trading at $0.7869). The economics are predictable, transparent, and optimized for high throughput at low cost – a major draw compared to legacy DA solutions or Ethereum L1 posting.
EigenLayer: Secure Restaking for Ethereum-Native DA
The other rising star in DA is EigenLayer, which takes a radically different approach by leveraging Ethereum’s security through restaking. Here’s how it works:
- Restaking ETH: Validators on Ethereum can opt-in to restake their ETH on EigenLayer services like EigenDA. This means they’re securing both Ethereum itself and additional protocols with the same capital base.
- Cascading Security: As of March 2025, EigenDA boasts 4.3 million ETH in restaked assets – representing billions in economic security backing its DA guarantees.
- No Direct Posting: Rollups don’t have to post all their data directly on Ethereum mainnet anymore; instead they leverage EigenDA’s high-throughput capabilities while inheriting Ethereum-grade security.
This shared security model accelerates innovation but comes with new considerations around slashing risks and potential cascading failures if vulnerabilities emerge across interconnected protocols. Still, for teams already deep in the Ethereum ecosystem or requiring maximum composability with existing dApps, EigenLayer provides an intuitive bridge into modular scalability.

The Modular DA Layer Showdown: Security vs Flexibility vs Cost
The choice between Celestia data availability (with its predictable blob economics) and EigenLayer secure restaking isn’t binary – it reflects project priorities around cost structure, risk tolerance, developer tooling preferences, and desired flexibility:
- Security Model: Celestia relies on its own proof-of-stake validators; EigenLayer inherits from Ethereum via restaking but introduces new slashing dynamics.
- Ecosystem Integration: Celestia offers language-agnostic support for custom VMs; EigenLayer dovetails seamlessly with Solidity-based projects.
- Permanence vs Ephemerality: Blobspace on Celestia is permanent; on some other networks blobs are temporary (e. g. , Dencun/Pectra forks).
This dynamic market continues to evolve rapidly as more teams build atop both platforms – pushing forward innovation in blobspace usage for modular rollups throughout 2025.
For investors and developers, the real question is: how do you position yourself as DA layers like Celestia and EigenLayer become foundational to the next generation of scalable, secure blockchains? The answer lies in understanding not just the technical differences, but also the economic and ecosystem impacts each solution brings.
Celestia’s predictable blob economics are already attracting a diverse set of rollups seeking low fees and long-term data guarantees. With TIA’s real-time price at $0.7869, cost modeling for rollup teams is transparent, blobs are priced per byte, with no surprise spikes or ephemeral storage risks. This predictability lets projects focus on scaling user adoption without worrying about sudden fee volatility or data expiry events that could disrupt their app’s reliability.
Meanwhile, EigenLayer is gaining momentum among Ethereum-native builders who want to maximize composability while benefiting from Ethereum’s robust validator set. Its restaking model means security scales with Ethereum itself, but it also means that any systemic risk or validator misbehavior can have outsized consequences across all protocols sharing this security pool. For DA maximalists, the tradeoff is clear: EigenLayer offers tighter integration with Ethereum’s DeFi stack but at the cost of inheriting its slashing and liveness risks.
Emerging Trends: Blobspace Usage and Rollup Deployment
As of late 2025, several trends are crystalizing:
- Blobspace demand is surging: More than 30 modular rollups now post data to Celestia’s blobspace, driving up network activity and developer mindshare. The permanence of blobs on Celestia is a major draw for applications needing auditable histories, think gaming, DePIN, and cross-chain bridges.
- Dencun/Pectra forks highlight ephemerality risks: Competing DA solutions built around temporary blob storage (such as those using Dencun or Pectra parameters) face criticism when data must persist for regulatory or compliance reasons. This has pushed many teams toward Celestia for mission-critical apps.
- Ecosystem composability: EigenLayer unlocks new possibilities for ETH-aligned projects by letting them tap into shared security pools without direct L1 posting costs. This accelerates experimentation but requires robust monitoring of validator health and slashing logic.
The bottom line? The modular DA landscape isn’t a zero-sum game, many projects will leverage both Celestia and EigenLayer depending on their needs. Expect hybrid deployments where core transaction data lands on Celestia for permanence while auxiliary state updates leverage EigenDA for speed and cost efficiency.
What to Watch as We Head Into 2026
If you’re building or investing in rollups, keep your eyes on:
- Blob pricing models: Will TIA remain stable around $0.7869, or will demand from new rollups push prices higher?
- Total ETH restaked on EigenLayer: Is the validator set diversifying fast enough to mitigate correlated slashing risk?
- Ecosystem bridges: Are new tools emerging that allow seamless switching between DA layers based on cost or security needs?
The race to scale decentralized applications securely, and profitably, is just heating up. Whether you’re optimizing for cost with permanent blobspace on Celestia or maximizing composability via EigenLayer’s secure restaking, one thing is clear: modular DA layers are rewriting the rules of blockchain infrastructure in real time.
