| Developer Flexibility | Lets projects evaluate NEAR DA alongside their execution, settlement, and storage infrastructure. |
2. Celestia (TIA)
Celestia is a modular blockchain network focusing on data availability and consensus. Other blockchains can then handle execution independently. Its core technologies are DAS (Data Availability Sampling) and NMTs (Namespaced Merkle Trees).
DAS enables light nodes to sample small parts of data to check whether a block is available without the need to download the whole block. NMTs enable applications to effectively retrieve the relevant data. These features allow developers to build application-specific blockchains and rollups without having to spin up a full data availability and consensus system from scratch.
The TIA token is used for a variety of functions within the Celestia ecosystem including staking and participation in the network. Celestia is especially useful for modular blockchain projects that need scalability, elastic execution environments and provable data availability.
Celestia (TIA) Feature

| Namespaced Merkle Trees | Helps applications retrieve and verify data relevant to their specific namespaces. |
| Scalable Blockspace | Supports modular rollups and application-specific blockchains requiring expandable data capacity. |
3. EigenDA (EigenLayer)
EigenDA is a high-throughput data availability service that leverages EigenLayer’s Ethereum restaking infrastructure. This means that rollups and other blockchain applications can publish transaction data without relying solely on Ethereum’s main execution layer for storage of that data.
EigenDA leverages a distributed operator network and cryptographic verification to achieve data availability at scale. Its architecture is designed to improve throughput while helping applications to handle data publication costs.
EigenDA is relevant for optimistic rollups, zero-knowledge rollups and other blockchain systems needing efficient data distribution. But its security model is different from Ethereum’s native blob mechanism, and depends on the service’s operator, verification and data retrieval arrangements. Developers should consider throughput, costs, integration needs, and security assumptions before choosing EigenDA.
EigenDA (EigenLayer) Feature
| Feature | Explanation |
|---|---|
| High Throughput | Designed to support substantial data publication demands from rollups and blockchain applications. |
| Ethereum Restaking | Uses EigenLayer’s restaking infrastructure to support its operator-based security model. |
| Cryptographic Verification | Uses cryptographic commitments and operator attestations to support data integrity and availability verification. |
| Rollup Compatibility | Provides a data availability service that rollups can integrate into their scaling architecture. |
4. Avail (AVAIL)
Avail is a modular blockchain infrastructure project that aims to provide secure, scalable data availability for rollups, application-specific chains, and other Web3 applications. Its technology is based on Data Availability Sampling and KZG polynomial commitments which allow participants to verify that published data is available without downloading everything.
The design is to reduce requirements on verification while supporting applications needing independent execution environments. Avail is designed to enable developers to build modular blockchain systems without requiring a fully separate data availability mechanism. The AVAIL token is the utility token for the network’s ecosystem, including participation in staking related activities.
Developers considering Avail and other options should weigh the costs of publishing data, the integrations offered, assumptions made about security, needs for retrieval, and compatibility with the execution and settlement layers they have chosen.
Avail (AVAIL) Feature
| Feature | Explanation |
|---|---|
| Data Availability Sampling | Enables light clients to check data availability without downloading complete blocks. |
| KZG Commitments | Uses cryptographic commitments to help verify published data efficiently. |
| Modular Blockchain Support | Supports rollups and application-specific blockchains with independent execution environments. |
| Scalable Data Infrastructure | Provides dedicated data availability infrastructure designed for growing blockchain data requirements. |
5. Ethereum (EIP-4844 / Blobs)
The Dencun upgrade introduced EIP-4844 to Ethereum that added blob-carrying transactions to make data publication cheaper for Layer 2 rollups. Blobs deliver ephemeral data availability at the Ethereum consensus layer and are priced separately from normal execution gas.
This enables rollups to publish transaction data at a lower cost than traditional calldata in many cases. The blobs in Ethereum are particularly useful for optimistic and zero-knowledge rollups, which require the transaction data to be available for validation or state restoration purposes.
Blobs are not permanent storage, however: Ethereum’s protocol ensures they will be available for a limited amount of time, initially around 18 days. Where an application requires historical access, suitable archival or external storage is to be arranged. For projects needing Ethereum-based security and an established ecosystem, Ethereum blobs are a strong option.
Ethereum (EIP-4844 / Blobs) Feature
| Feature | Explanation |
|---|---|
| Blob Transactions | Introduces dedicated blob-carrying transactions for rollup data publication. |
| Lower Data Costs | Helps reduce rollup data expenses compared with traditional calldata in many cases. |
| Ethereum Security | Uses Ethereum’s consensus infrastructure to support blob data availability. |
| Temporary Data Storage | Retains blob data temporarily, requiring separate archival solutions for long-term access. |
6. 0G (ZeroGravity)
0G is building decentralized infrastructure for data availability, storage and artificial intelligence applications. Its architecture isolates critical functions so that applications can process large volumes of data without relying on a single layer of blockchain to provide all storage and processing capabilities.
The project is aimed at demanding use cases such as AI agents, decentralized computing and data-heavy Web3 applications. Its data availability infrastructure is designed to enable applications to publish, distribute and verify data in an efficient way while supporting scalable network operations.
For developers, 0G could be worth evaluating if a project combines blockchain functionality with AI workloads or large data requirements. However, data availability, permanent storage and computation services are separate functions and the user should evaluate the particular service, verification mechanisms, costs and the security guaranties offered.
0G (ZeroGravity) Feature

7. B-Squared Network (B²)
B² Network is a Bitcoin-centric Layer 2 project that seeks to bring scalable intelligent contracts and decentralized applications with a link to the Bitcoin ecosystem. Its general architecture is a combination of Layer 2 execution and mechanisms for data availability and verification.
This can help applications to process transactions off of Bitcoin’s base layer, but still maintain relevant security and settlement connections. B² is especially attractive to developers looking to build decentralized finance, intelligent contracts, and other use cases on Bitcoin that require more flexibility than the base network.
Its full security model, however, depends on the particular Layer 2 design, proof mechanisms, and data retrieval arrangements. Developers should consider how transaction data is published, how proofs are verified and what assumptions users have to trust when using the B² network.
B-Squared Network (B²) Feature
| Feature | Explanation |
|---|---|
| Bitcoin Layer 2 | Focuses on expanding Bitcoin’s capabilities through Layer 2 infrastructure. |
| Smart Contract Support | Targets applications requiring programmable functionality beyond Bitcoin’s base layer. |

8. Unibase
Unibase is focused on the infrastructure for AI agents, specifically the persistent memory and data management that can help agents remember information across interactions. This is relevant for developers building autonomous agents and applications that need structured access to historical context.
Where Unibase is positioned is mainly around AI-agent infrastructure, and not as a direct like-for-like blockchain DA layer, like dedicated data availability networks like Celestia. Thus, its relevance to data availability depends on the particular products and infrastructure being evaluated.
Developers looking at Unibase should consider how agent memories are stored, retrieved, verified and shared, alongside privacy, reliability and integration requirements. It may complement AI agent-based blockchain applications, but its capabilities should be evaluated separately from networks specifically constructed for rollup transaction data availability.
Unibase Feature
| Feature | Explanation |
|---|---|
| AI-Native Data Infrastructure | Focuses on high-throughput data storage and verification for AI workloads. |
| Programmable Data Access | Provides tools for uploading, verifying, and retrieving data programmatically. |

9.Sunrise Layer
Sunrise Layer is designed to enable data availability for rollups and application-specific blockchains in a high throughput. Its recorded architecture uses off-chain blob propagation and erasure coding, and on-chain metadata points to data shards stored through external systems like IPFS or Arweave.
This approach aims to directly reduce the amount of data validators need to process on-chain, and thus to improve scalability and cost efficiency. Sunrise also describes a positive verification process where challenges can lead to further validation.
This design decision makes it applicable to applications with heavy data publication requirements. But off-chain storage raises key questions around retrievability, verification and infrastructure dependencies.
According to the documentation for Sunrise, the original Cosmos Sunrise network is set to shut down on October 5, 2026 and migrate to Sunrise Edge. That date has passed , so readers should check the current status and architecture before using older Sunrise documentation .
Sunrise Layer Feature
| Feature | Explanation |
|---|---|
| Off-Chain Blob Storage | Keeps large data blobs off-chain while publishing metadata references on-chain. |
| Erasure Coding | Splits data into encoded shares to support reconstruction and reduce on-chain storage requirements. |

Its services have been designed to make blockchain data more easily queryable for applications such as analytics dashboards, portfolio trackers, decentralized finance tools, and Web3 research platforms.
Covalent is relevant for the broader data infrastructure ecosystem, but should not be confused with a dedicated data availability layer like Celestia or EigenDA. The purposes of data indexing and retrieving historical data are different from the purposes of providing transaction data for independent verification.
Developers should evaluate supported chains, API coverage, historical data access, query limits, pricing, and data completeness when evaluating Covalent. It can complement a data availability solution, by making blockchain information easier to consume, but does not automatically replace the underlying network’s data availability mechanism.
