Ethereum's PeerDAS Upgrade Delivers 8x Throughput Boost in 3 Weeks
**Ethereum's PeerDAS upgrade launches in approximately 3 weeks**, delivering the network's biggest scalability improvement since Layer-2 rollups.
**How PeerDAS Works:**
- Splits transaction data into **128 pieces** instead of sending full data to every node
- Each validator only stores and verifies **8 out of 128 pieces** (1/16th of original data)
- Uses **erasure coding** - data can be fully reconstructed from just 50% of pieces
- Reduces storage requirements from 768kb to **96kb per validator**
**Key Benefits:**
- **8x network throughput increase** without hardware upgrades
- Maintains **decentralization** by keeping home stakers viable
- Applies specifically to **Layer-2 blob data**, amplifying L2 transaction capacity
- Preserves full data availability and security guarantees
**Technical Innovation:**
Nodes are organized into 128 gossip networks, each responsible for one data piece. Every validator participates in at least 8 groups, ensuring redundancy while dramatically reducing individual resource requirements.
This upgrade addresses Ethereum's core challenge: scaling transaction volume while keeping validation accessible to independent operators, not just large institutions with expensive hardware.
