Benchmarking Blockchain Data Availability: Polkadot ELVES vs Modular DA Layers

[prasad-kumkar]

Project Abstract

We propose a comprehensive research study comparing the data availability (DA) mechanisms of Polkadot’s integrated availability protocol (used in ELVES) with those of leading blockchain DA schemes like Celestia, Avail, Espresso's Tiramisu, and NEAR. Our goal is to evaluate and benchmark these systems on key performance, security, and efficiency metrics, such as bandwidth usage, latency, light-client trust assumptions, and validator resource overhead. We will use real network telemetry from Polkadot/Kusama, Celestia mainnet, Avail testnet, and other platforms, along with protocol analysis and reproducible experiments, to generate a detailed and objective comparison.

The research will deliver a deeply technical report, open-source benchmarking tools, and curated datasets, all licensed openly under Apache-2.0 and CC BY 4.0. The findings will inform protocol developers, parachain teams, and researchers about the strengths and trade-offs of each approach, and highlight Polkadot's positioning in a growing ecosystem of modular and scalable blockchain architectures. We also propose optional dissemination via an interactive dashboard, tutorial videos, and blog posts to maximize the accessibility and long-term value of the research.

This proposal is in response to the Research Task shared by W3F.
