Expand description
A feature index used to identify a bit into the node_features array stored in the HostConfiguration.
Variants§
EnableAssignmentsV2 = 0
Tells if tranch0 assignments could be sent in a single certificate.
Reserved for: <https://github.com/paritytech/polkadot-sdk/issues/628>
ElasticScalingMVP = 1
This feature enables the extension of BackedCandidate::validator_indices
by 8 bits.
The value stored there represents the assumed core index where the candidates
are backed. This is needed for the elastic scaling MVP.
AvailabilityChunkMapping = 2
Tells if the chunk mapping feature is enabled.
Enables the implementation of
RFC-47.
Must not be enabled unless all validators and collators have stopped using req_chunk
protocol version 1. If it is enabled, validators can start systematic chunk recovery.
CandidateReceiptV2 = 3
Enables node side support of CoreIndex
committed candidate receipts.
See RFC-103 for details.
Only enable if at least 2/3 of nodes support the feature.
FirstUnassigned = 4
First unassigned feature bit. Every time a new feature flag is assigned it should take this value. and this should be incremented.
