From 0d967fd3dbfff9b451cccde2400354d5193f27ad Mon Sep 17 00:00:00 2001 From: Arijit Das Date: Mon, 8 Nov 2021 16:26:10 +0530 Subject: [PATCH] feat(mint): Implement custom inflation function. (#10441) ## Description We want to use this feature in [Akash Network](https://akash.network/). The [Akash whitepaper](https://whitepaper.io/document/632/akash-network-whitepaper) defines a time-based function for the inflation: `I(t)`. The way `cosmos-sdk` currently calculates inflation is different as compared to what the Akash whitepaper prescribes. So, we need the `cosmos-sdk` to accept a custom function to calculate inflation. When the custom function isn't provided, it should use the default inflation calculation logic as it currently does. --- ### Author Checklist *All items are required.
