Availability Subsystems: availability recovery subsystem #3604

Open kishansagathiya opened 10 months ago

kishansagathiya commented 10 months ago

Issue summary

This subsystem is the inverse of the Availability Distribution subsystem: validators will serve the availability chunks kept in the availability store to nodes who connect to them. And the subsystem will also implement the other side: the logic for nodes to connect to validators, request availability pieces, and reconstruct the AvailableData.

Requires skeleton and thus sub-issues. Estimating it at 8, until additional details and sub-issues arrives.
