Data Availability Infras

The Data Availability Layer (DAL) is the input layer for W3bstream. It can be either a centralized service or a decentralized network that stores blocks of data for a specified period as determined by a DePIN project. Once this period expires, the data may be immediately deleted or transferred to a dedicated Long-Term Storage Layer. Depending on the project's configuration, the DAL also periodically commits data sets (e.g., a hash) to the IoTeX Blockchain to ensure data integrity.

Supported DA Infra

While IoTeX does not provide any Data Availability DIM, W3bstream will support popular Data Availability (DA) infrastructures. We anticipate that third-party projects will develop DIMs to serve as DA layers, integrating seamlessly with W3bstream.

Reference Implementation

A W3bstream-compatible DA Layer should implement a simple interface.

W3bstream provides a reference implementation for a Postgres DB.
