EigenLayer

EigenLayer enhances Ethereum's modularity by enabling developers to build applications that leverage Ethereum's security while introducing customizable layers for specific needs. Here we focus on EigenDA, the data availability solution that enables MegaETH's breakthrough performance.

Understanding Data Availability

Data availability (DA) ensures all transaction data is publicly accessible so anyone can verify state changes. It's essentially the blockchain "showing its work" - without it, operators could manipulate records like a centralized database.

Who needs DA solutions?

• Blockchains that outsource consensus to Ethereum (like MegaETH)

• High-performance rollups exceeding Ethereum's native capacity

• Applications requiring more than ~400 TPS globally

Ethereum's DA Limitations

Since the Dencun upgrade, Ethereum uses "blobs" for rollup data:

• Current capacity: 64 KB/s (6 blobs × 128KB ÷ 12 seconds)

• Supports: ~100 Megagas/s & ~400 TPS shared across ALL rollups

• Base alone uses: 25-30% of blob space at just 120 TPS

• Blob pricing: Increases exponentially above target to prevent congestion

• Future roadmap: Even with PeerDAS (2026), only 48 blobs expected

The problem: MegaETH targets 10 Gigagas/s and 100K TPS, requiring ~20MB/s of DA throughput - 300x more than Ethereum provides.

EigenDA: Breaking Through Limits

EigenDA solves this bottleneck with a fundamentally different architecture:

Current Performance:

• 15 MB/s throughput (live on mainnet)

• 50 MB/s on V2 testnet

• 800x Ethereum's capacity

• Supports 250,000+ ERC-20 transfers/second

Key Innovations:

• Horizontal scaling: Capacity increases as operators join

• Erasure-coded sharding: Data split across operators with KZG commitments

• Cryptographic proofs: Operators prove data authenticity

• Redundancy: Reconstructs data even if some shards missing

How MegaETH Uses EigenDA

The integration creates a dual-layer approach:

1. Sequencer submits transaction batches to EigenDA

2. Data is erasure-coded and distributed across operators

3. Operators validate and return BLS signatures

4. Signatures aggregate into a DA Certificate

5. Certificate verified on Ethereum via EigenDA Verifier contract

6. MegaETH posts State Root to Ethereum for security anchoring

Result: Ethereum's security + EigenDA's throughput = Real-time blockchain performance

Why This Matters

• No compromises: Full Ethereum security with 100K+ TPS capability

• Future-ready: EigenDA roadmap aligns with MegaETH's scaling trajectory

• Enables new applications: Performance previously impossible on-chain

• Slashing mechanism: Financial penalties ensure operator reliability
