The multi-staking-module is a module that allows the cosmos-sdk staking system to support many types of token

Given the fact that several core sdk modules such as distribution or slashing is dependent on the sdk staking module, we design the multi staking module as a wrapper around the sdk staking module so that there's no need to replace the sdk staking module

The multi staking module has the following features:

• Staking with many diffrent type of tokens
• Bond denom selection via Gov proposal
• A validator's delegations can only be in one denom
