Introduction: Why Data Availability Layers Matter in November 2025

Data availability layers let rollups publish transaction data so anyone can reconstruct state and verify proofs. In 2025, modular stacks (OP Stack, Polygon CDK, ZK Stack) routinely separate execution from DA to optimize costs and performance. Your DA choice affects security (trust assumptions), fees (blob gas vs. DA network fees), and UX (latency, bandwidth caps).
Search intent here is commercial-investigational: teams comparing providers by cost, security model, and integration options. We’ll keep things concrete, link only official sources, and show exactly who each option fits.

How We Picked (Methodology & Scoring)

  • Liquidity/Scale — 30%: adoption, throughput, sustained bandwidth.
  • Security — 25%: trust assumptions (L1 blobs vs. DAC), transparency, docs.
  • Coverage — 15%: SDKs, stacks supported (OP Stack, Polygon CDK, ZK Stack), bridges.
  • Costs — 15%: posted pricing/fee mechanics.
