Update of protocol parameters +authors: [Alexey Kuleshevich] +tags: [Accepted] +--- + +## Status + +Accepted + +## Context + +We need an unified approach for predicting and updating protocol parameters. + +Outline of the new approach. + +### Shelley through Babbage: + +1. Genesis key holders submit votes with proposals for new `PParams`. Depending on the + timeing within the epoch those votes will either go into the current or the future + proposals bucket. +2. During the first `4k/f` slots in the the PPUP rule PParamUpdate proposals added to + current proposals. Besides keeping the proposals we also now keep potential protocol + parameters in the future pparms, but only quorum of genesis votes is reached. Potential + values for new `PParams` can change if genesis key holders change their votes during + this period, therefore they cannot yet be considered stable. +3. The very first `TICK` that happens during the last two stability windows before the end + of the epoch we solidify the proposed `PParams`, thus ensuring they will be applied at + the next epoch boundary. (See `solidifyNextEpochPParams`) +4. At the epoch boundary during the `NEWPP` rule, instead of counting the votes on the + proposals, we just looked up in the next `PParams` that were decided earlier and apply + them. All of the future votes that where potentially submitted before during the last + two stability windows of past epoch are converted to current votes, which will be + treated in the same way as if they were submitted in the 2nd step. This also resets the + future PParams for the next epoch. + +### Conway era forward + +1. Either `ParameterChange` or `HardForkInitiation` proposal is submitted and votes are + collected. +2. At the epoch boundary all of the votes and proposals are snapshotted. +3. Pulser starts the work on every `TICK` figuring out the stake distribution for `DReps`, + calculating the votes and ratifying the proposals. Whenever `ParameterChange` or + `HardForkInitiation` gets ratified in the `RATIFY` rule, the new values are immediately + applied to the future enact state by the `ENACT` rule. Therefore we have future + `PParams` at the latest two stability windows before the end of the epoch. +4. During the first `4k/f` slots on every tick we also lazily update future `PParams`. +5. Just as in Shelley era the very first `TICK` that happens during the last two stability + windows (`6k/f`) before the end of the epoch we solidify the proposed `PParams`. (See + `solidifyNextEpochPParams`). Unlike previous eras, in Conway this step is safe to do at + any point during the initial part of the epoch, because they are considered stable as + soon as we enter new epoch, however they are expensive to compute during that period, + that is why we solidify them only when we are pretty confident that the DRep pulser is + done and `RATIFY` with `ENACT` rules got a chance to be executed. +6. At the epoch boundary we apply the new PParams that where solidified in the previous + step and reset the future pparams, thus making it ready for the next epoch. The + important part here is that we do not use the values from the Enact state directly, but + we take the futurePParams as the source of truth. This allows us to correctly update + the `PParams` not only using the voting process of Conway era, but allows us to apply + the `PParams` update from Babbage era. + +### Forecast + +It is very important that the TICKF rule does the same steps as the TICK and EPOCH (for +Conway) or NEWPP (for pre Conway) rules. In particular same solidification and rotation of +pparams process as in the stepsabove should happen for forcasting to work correctly. + +## Decision + +New approach to update has been implemented. + +## Consequences + +* We have a unified approach to update PParams throughout all eras starting with Shelley, + thus making HFC combinator much more robust and correct. +* We remove duplicate logic from consensus that used to count up the genesis key holder votes. +* We solve a problem where HFC is triggered in previous era, while TICK happens in the new + era after translation. Which previously caused protocol version not being updated + correctly in Conway, since protocol parameter update mechanism was vastly different from + the one in Babbage. +* We finish implementation of HardForkInitiation into a new era. diff --git a/eras/allegra/impl/src/Cardano/Ledger/Allegra/PParams.hs b/eras/allegra/impl/src/Cardano/Ledger/Allegra/PParams.hs index b0b5f2da656..01b7d20b941 100644 --- a/eras/allegra/impl/src/Cardano/Ledger/Allegra/PParams.hs +++ b/eras/allegra/impl/src/Cardano/Ledger/Allegra/PParams.hs @@ -43,12 +43,7 @@ instance Crypto c => EraPParams (AllegraEra c) where instance Crypto c => EraGov (AllegraEra c) where type GovState (AllegraEra c) = ShelleyGovState (AllegraEra c) -
