Data Availability Servers (DAS)

PreviousDual Data Posting MechanismsNextSequencer-Committee Interaction

Last updated 5 months ago

Committee members operate Data Availability Servers (DAS), which expose two essential APIs:

  1. Sequencer API: Meant exclusively for use by the Arbitrum chain's Sequencer, this JSON-RPC interface enables the Sequencer to submit data blocks to the DAS for storage.

  2. REST API: Designed for broader accessibility, the RESTful HTTP(S)-based protocol allows data blocks to be retrieved by hash. It is fully cacheable, and deployments may incorporate caching proxies or CDNs to enhance scalability and protect against potential DoS attacks.

Xai, along with Ex Populus and another trusted third party, are proud members of the Data Availability Committee (DAC). This setup allows AnyTrust chains to depend on a specialized DAC, rather than their parent chains, for data availability. The DAC members operate Data Availability Servers (DAS) which are crucial for storing and providing data on-demand.

Below are the public keys for each of the trusted members. These keys can be used to authenticate and verify data signed by the respective entities within the Xai DAS ecosystem:
