The PeerDAS protocol, officially known as EIP-7594, was introduced as a key feature of the Fusaka hard fork on December 3, 2025. It allows Ethereum validators to verify data availability by sampling only one-eighth of the dataset rather than downloading full blocks. This approach enables nodes to operate on standard consumer hardware while maintaining network consensus.
Following the launch, the network capacity for blobs per block increased from an initial target of 6–9 to 10 by December 9, 2025, and reached 14 by January 7, 2026. This scaling was preceded by extensive testing on a dedicated devnet involving hundreds of nodes. The protocol builds upon the foundation of the EIP-4844 upgrade implemented in early 2024.
The implementation has contributed to a significant reduction in Layer 2 transaction costs. Before the activation of PeerDAS, fees ranged from $0.20 to $0.50 per transaction. By the first quarter of 2026, these costs dropped to between $0.005 and $0.02, representing a decrease of more than 95%.
PeerDAS represents an early phase of the broader danksharding architecture proposed by Dankrad Feist. While current capacity is measured in dozens of blobs, full implementation of danksharding aims to support thousands of blobs per block. Vitalik Buterin has identified the protocol as a significant development for blockchain scalability.
