* Only send one collation per relay parent at a time to validators This changes the way we are sending collations to validators. Before we answered every collation request immediatley. Now we only answer one pov request at a time per relay parent. This should bring down the bandwidth requirements and should help parachains to include bigger blocks more easily. * Guide updates * Review feedback.
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.
