EigenDA Supports Data Availability Solutions for Arbitrum Orbit

According to EigenDA‘s announcement, the platform will collaborate with Arbitrum to support and provide Data Availability for Arbitrum Orbit.

Big news… 🥁 EigenDA now works with @arbitrum Orbit! 🛰️ Thanks to @alt_layer's fork of Arbitrum Nitro, rollup teams can now use EigenDA to scale Orbit chains far beyond the Ethereum block size limit without sacrificing decentralization. 👨‍🍳🤌 pic.twitter.com/NNX3JLWG9r

After integrating the Data Availability mechanism from EigenDA, transaction data on Layer-2 will be sent to the EigenDA-managed contract on Layer-1 (instead of the current simple calldata mechanism). This data will be restructured into blobs to save storage space while sending these “certificates” to Layer-2 to continue verification on Layer-1.

This approach will help Layer-2 (specifically Rollup) save verification costs, pushing transaction processing capabilities up by over 50 times.

At the time of writing, the integration of EigenDA with the Arbitrum Orbit toolkit is still undergoing testing on the Sepolia testnet.

As part of the ongoing partnership between @eigen_da and @alt_layer, the EigenDA fork of the Arbitrum Orbit suite will be actively maintained to keep up with changes upstream. 📋

EigenDA also mentioned that the current version has not integrated Fraud Proof and may require multiple updates in the future to add this verification mechanism to the solution.

Additionally, infrastructure from AltLayer is also involved in supporting the integration process to make it more seamless.

In December 2023, EigenLayer also announced a collaboration with AltLayer (a Rollup-as-a-Service provider) to develop the Restaked Rollup mechanism, addressing some current limitations such as Sequencer centralization, MEV, or finality speed.

Earlier, EigenLayer also announced the integration of the EigenDA solution into the OP Stack toolkit (another counterpart to Arbitrum Orbit).
