Trading Notes | Data Availability
① Ethereum’s December 2025 Fusaka upgrade introduced PeerDAS, so nodes no longer need to download the full blob data; they can confirm data availability by sampling just a portion of it.
② DAS is typically used with erasure coding: data is encoded with redundancy, and the full dataset can be reconstructed as long as a sufficient proportion of the fragments is available.
③ When comparing Layer 2 solutions, pay attention to where transaction data is stored: on Ethereum, on an independent data availability network, or with an off-chain committee. Each has different security assumptions.
