A per-kind default bucket. Each bucket covers a disjoint subset of
DenyElementKind; a proposed element of one of element_kinds activates when
eligible voting stake reaches threshold.
Configuration for activating recommended TransactionDenyConfig rules shared by
peers via consensus. The operator pre-defines named rulesets, each gated on a
stake threshold among an eligible set of validators; per-kind “default” buckets
govern individual rule elements peers propose outside of any pre-listed ruleset.
A pre-listed ruleset becomes effective when validators holding at least
threshold.stake_threshold_percent of the eligible stake have each proposed a
superset of rules.
