* First step in implementing https://github.com/paritytech/polkadot/issues/4386 This PR: - Reduces MAX_UNSHARED_UPLOAD_TIME to 150ms - Increases timeout on collation fetching to 1200ms - Reduces limit on needed backing votes in the runtime This PR does not yet reduce the number of needed backing votes on the node as this can only be meaningfully enacted once the changed limit in the runtime is live. * Fix tests. * Guide updates. * Review remarks. * Bump minimum required backing votes to 2 in runtime. * Make sure node side code won't make runtime vomit. * cargo +nightly fmt
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.
