Data Availability Servers (DAS)

Operated by Committee members, Data Availability Servers (DAS) offer two critical APIs:

  • Sequencer API: This API, utilizing the JSON-RPC protocol, is reserved for the Arbitrum chain's Sequencer, facilitating the upload of data blocks to the DAS for preservation.

  • REST API: Aimed at wider use, this RESTful HTTP(S) protocol permits the fetching of data blocks via their hash. It supports full caching, allowing for the integration of caching proxies or Content Delivery Networks (CDNs) to boost scalability and mitigate the risk of DoS attacks.
