* Introduce a "dynamic" block size limit for proposing This adds support for using a dynamic block size limit per call to `propose`. This is required for Cumulus/Parachains to always use stay in the limits of the maximum allowed PoV size. As described in the docs, the block limit is only checked in the process of pushing transactions. As we normally do some other operations in `on_finalize`, it can happen that the block size still grows when there is some proof being collected (as we do for parachains). This means, that the given block limit needs to be rather conservative on the actual value and should not be the upper limit. * Update client/basic-authorship/src/basic_authorship.rs Co-authored-by: Andronik Ordian <write@reusable.software> * More future proof encoded size updating * Use `ProofRecorderInner` * Update client/basic-authorship/src/basic_authorship.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/basic-authorship/src/basic_authorship.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/basic-authorship/src/basic_authorship.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/consensus/slots/src/lib.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/consensus/slots/src/slots.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/basic-authorship/src/basic_authorship.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/basic-authorship/src/basic_authorship.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/basic-authorship/src/basic_authorship.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> Co-authored-by: Andronik Ordian <write@reusable.software> Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com>
Aura (Authority-round) consensus in substrate.
Aura works by having a list of authorities A who are expected to roughly agree on the current time. Time is divided up into discrete slots of t seconds each. For each slot s, the author of that slot is A[s % |A|].
The author is allowed to issue one block but not more during that slot, and it will be built upon the longest valid chain that has been seen.
Blocks from future steps will be either deferred or rejected depending on how far in the future they are.
NOTE: Aura itself is designed to be generic over the crypto used.
