or you could do fixed per second so you don't incentivize block acceleration |
Replace percentage-based inflation with fixed 4 SCRT per block emissions. This ensures predictable, sustainable token issuance that doesn't grow indefinitely with supply. Changes: - Add custom x/mint module with fixed block rewards - Set fixed reward to 4 SCRT (4,000,000 uscrt) per block - Create v1.24 upgrade handler for migration - Update app to use custom mint module instead of Cosmos SDK mint Impact: - Immediate ~30% reduction in inflation (from ~9% to ~6.2%) - Annual emissions constant at ~21M SCRT regardless of supply - Inflation naturally decreases over time as supply grows - Year 5: ~4.8% inflation, ~11% APR - Year 10: ~3.9% inflation, ~9% APR 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Use store service directly instead of mixing with sdk.Context.KVStore(). This follows the Cosmos SDK v0.50 pattern for store access. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

@zenopie I think you actually hard coded blocktime assumptions, but best practice differs. What you'd likely want to do is replace the hard coded calculation of blocks per year to BlocksPerYear. This is a target, not protocol enforcable due to real world network conditions and the ability of node runners to change node config timings. It has drifted in the past, and when it does, maintenance via gov is done by doing a param change proposal to match. |
Instead of hardcoding BlocksPerYear from block time assumptions, read the existing governance-managed value from chain state. This allows governance to adjust BlocksPerYear via param change proposals when block times drift, without requiring code changes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Description:
Summary
Replaces percentage-based inflation with fixed 4 SCRT per block emissions for sustainable, predictable
tokenomics.
Problem
Current percentage-based inflation causes emissions to grow indefinitely with supply:
Solution
Fixed block rewards: 4 SCRT per block = constant 21M SCRT/year
Impact
Changes

TODO Before Merge
Testing Checklist
Note: This is a DRAFT PR. Core logic is implemented but needs tests, query endpoints, and testnet
validation before merge.
