Decoupling data availability from blockchain execution

EigenDA is a decentralized data availability service built on Ethereum using EigenLayer's restaking infrastructure. It enables rollups and blockchain applications to distribute and retrieve data without placing the full data workload on the settlement layer.

It separates data availability from execution, allowing rollup architectures to use a dedicated layer for blob dispersal, operator storage, verification, and retrieval. Its V2 architecture introduced a redesigned certificate and verification flow along with infrastructure for higher-scale DA workloads.

For modular blockchain architectures, EigenDA can serve as the DA layer while execution and settlement remain within the rollup's own stack.

How EigenDA handles data availability

EigenDA processes blockchain data through a distributed lifecycle that moves a blob from submission and encoding to certification and retrieval.

Blob submission

Rollup or application data is submitted as blobs through EigenDA's dispersal infrastructure.

Erasure coding

The submitted data is encoded into multiple chunks, creating redundancy that supports data recovery when individual chunks or operators are unavailable.

Operator distribution

Encoded chunks are distributed across participating operators, which maintain the assigned data and participate in the availability certification process.

Availability certification

Operators provide cryptographic attestations over the data they hold. These attestations contribute to the generation of a data availability certificate.

Certificate verification

Availability certificates can be verified through EigenDA's verification infrastructure, allowing integrated blockchain systems to validate the availability commitment.

Data retrieval

When the data is required, retrieval infrastructure obtains the relevant chunks and reconstructs the original blob.

Bring dedicated data availability into your blockchain architecture

EigenDA enables rollups and modular blockchain systems to separate data availability from execution and settlement, supporting scalable data publication, verification, and retrieval.

Modular blockchain architectures

Position EigenDA within a modular stack where execution, data availability, and settlement operate as distinct infrastructure layers.

Appchains & application-specific networks

Integrate EigenDA into application-specific chains that require dedicated infrastructure for publishing, verifying, and accessing blockchain data.

High-throughput blockchain systems

Apply EigenDA to blockchain architectures handling substantial data volumes, where dedicated availability infrastructure can support scalable data publication and retrieval.

EigenDA integration architecture

Integrating EigenDA requires coordination between the DA layer and the surrounding rollup or blockchain components.

Rollup data flow

Define how transaction data moves from the sequencer or batcher into EigenDA and how the resulting availability information is propagated to the settlement layer.

Certificate verification

Map EigenDA certificate verification to the blockchain's validation and settlement architecture.

Retrieval design

Define how validators, nodes, and applications access previously published data and how retrieved chunks are reconstructed.

Operator infrastructure

Account for networking, storage, Ethereum RPC connectivity, key management, resource allocation, node configuration, and infrastructure health.

Performance requirements

Evaluate dispersal latency, retrieval performance, throughput, network capacity, and resource requirements against the target workload.

Upgrade compatibility

Build permissions, transaction limits, approvals, monitoring, reconciliation, and audit trails directly into the treasury architecture and daily operational workflows.

EigenDA V2

EigenDA V2 extends the architecture across data dispersal, certification, verification, retrieval, and related infrastructure.

Built for business needs

Develop solutions with a focus on security, scalability, performance, and reliability.

Scalable data availability

The architecture is designed to support higher-volume data availability workloads through distributed dispersal and operator infrastructure.

Retrieval infrastructure

V2 includes mechanisms for accessing distributed data and reconstructing blobs when required by integrated applications and blockchain participants.

Integration model

The implementation approach depends on the rollup framework, data publication workflow, settlement architecture, verification requirements, and retrieval design.
