ParamChange: Increase Max Block Gas Limit

Title

Increase Maximum Block Gas Parameter for cosmoshub from 40M to 100M

Context

With ICS being active and there being more tokens to claim as rewards on every staking/ unstaking/ withdraw transaction, the gas required to process these transactions has increased significantly to approximately 20K per additional token claim. While this does not affect cosmoshub users, it limits liquid staking providers and their ability to delegate and claim rewards from large validator sets, as their transactions are going out of gas.

Solution

To help protocols allow stake distribution to their entire validator set and to potentially increase validator set we should increase the max block limit. At the same time this gives liquid staking providers time to implement other means to reduce number of transactions or transaction size.

Currently Osmosis (120M), Persistence (100M), Quicksilver (150M), Stride (Infinite) have higher gas limits and have not slowed down block production.

This proposal was not put up for discussion on the forum as it is time-sensitive for the pSTAKE protocol as unstaking transactions are going out of gas. One can read more here
