Non-Interactive Staking (#12610)
* Improve naming. * More improvements to naming * Fungible counterpart * Shared pot instead of reserve * Transferable receipts * Better naming * Use u128 for counterpart * Partial thawing * Docs * Remove AdminOrigin * Integrate into Kitchen Sink * Thaw throttling * Remove todo * Docs * Fix benchmarks * Building * Tests work * New benchmarks * Benchmarking tests * Test new defensive_saturating_* functions Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * fmt Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Formatting * Update frame/nis/src/lib.rs Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Apply suggestions from code review Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Events added * Fix kitchensink * Update frame/nis/src/lib.rs Co-authored-by: Xiliang Chen <xlchen1291@gmail.com> * Review niggles * Remove genesis build requirements * Grumbles * Fixes * Fixes * Fixes * Update frame/nis/src/lib.rs Co-authored-by: Kian Paimani <5588131+kianenigma@users.noreply.github.com> * Update primitives/runtime/src/traits.rs Co-authored-by: Kian Paimani <5588131+kianenigma@users.noreply.github.com> * Formatting * Fixes * Fix node genesis config Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Fix node chain specs Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Use free asset ID as counterpart Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> * Account for rounding errors in fund_deficit bench Relaxes the check for the NIS account balance in the fund_deficit bench from equality from to checking for 99.999% equality. The exact deviation for the kitchensink runtime config is 1.24e-10 percent but could vary if the config is changed.
