feat: 2s blocktime by cl0w5 · Pull Request #1435 · galacticcouncil/hydration-node

cl0w5 · 2026-04-30T15:05:58Z

Summary

Updates Hydration from 6-second to 2-second block production while preserving existing wall-clock behavior where required.

This includes runtime and node configuration changes, recalibrated per-block parameters, and migrations for active block-number-based state.

Checklist

Migrations

The migrations below are designed to fit in a single block. Migrations that iterate over storage contain hard caps sized above the current mainnet entry counts.

hydradx_runtime::migrations::parameters::SetTwoSecBlocksSince
- Stores the transition block once in pallet-parameters.
- Staking and GigaHDX access it through a shared Get<BlockNumber> provider.
pallet_dca::migrations::MultiplySchedulesPeriodBy3
hydradx_runtime::migrations::circuit_breaker::MigrateCircuitBreakerTo2sBlocks
- Migrates per-asset limits and active lockdown state.
hydradx_runtime::migrations::dynamic_fees::MigrateDynamicFeeDecayTo2sBlocks
hydradx_runtime::migrations::stableswap::MigrateStableswapMaxPegUpdateTo2sBlocks
hydradx_runtime::migrations::scheduler::MigrateSchedulerTo2sBlocks
- Drains the existing agenda before inserting migrated entries to avoid key collisions.
hydradx_runtime::migrations::referenda::MigrateReferendaTo2sBlocks
hydradx_runtime::migrations::conviction_voting::MigrateConvictionVotingTo2sBlocks
