Key Takeaways: Data Availability
DAS is usually used together with erasure coding: data is encoded with redundancy, and the entire dataset can be reconstructed as long as a sufficient proportion of the pieces is available.
Ethereum's Fusaka upgrade, launched in December 2025, introduced PeerDAS. Nodes don't need to download the full blob data; they can check a sample to confirm data availability.
When comparing Layer 2 solutions, pay attention to where transaction data is published: Ethereum, an independent data availability network, or an off-chain committee. Each has different security assumptions.
$TIA is the native token of Celestia, a public blockchain dedicated to data availability. Current price: 0.4412.
