Closes #1591. The purpose of this PR is filter out backing statements from the network signed by disabled validators. This is just an optimization, since we will do filtering in the runtime in #1863 to avoid nodes to filter garbage out at block production time. - [x] Ensure it's ok to fiddle with the mask of manifests - [x] Write more unit tests - [x] Test locally - [x] simple zombienet test - [x] PRDoc --------- Co-authored-by: Tsvetomir Dimitrov <tsvetomir@parity.io>
Preamble
This document aims to describe the purpose, functionality, and implementation of the host for Polkadot's parachains functionality - that is, the software which provides security and advancement for constituent parachains. It is not for the implementer of a specific parachain but rather for the implementer of the Parachain Host. In practice, this is for the implementers of Polkadot in general.
There are a number of other documents describing the research in more detail. All referenced documents will be linked here and should be read alongside this document for the best understanding of the full picture. However, this is the only document which aims to describe key aspects of Polkadot's particular instantiation of much of that research down to low-level technical details and software architecture.
