## Description

Closes: #8961 

SDK allows InitGenesis to return with an empty validator set. In practice, the error for an empty validator set gets thrown in tendermint. To fix this,

* Add non-empty validator set check to the `mm.InitGenesis` function. This will break `simapp.Setup` because it relies on an empty validator set [#comment](https://github.com/cosmos/cosmos-sdk/pull/8909#issuecomment-804850834).
* Update `simapp.Setup` to use a single validator.
* Fix failing tests (Most of them are keeper tests).

<!-- Add a description of the changes that this PR introduces and the files that
are the most critical to review. -->

Cosmos SDK

banner

The Cosmos SDK is a framework for building blockchain applications. Tendermint Core (BFT Consensus) and the Cosmos SDK are written in the Golang programming language. Cosmos SDK is used to build Gaia, the first implementation of the Cosmos Hub.

WARNING: The Cosmos SDK has mostly stabilized, but we are still making some breaking changes.

Note: Requires Go 1.17+

Quick Start

To learn how the Cosmos SDK works from a high-level perspective, see the Cosmos SDK High-Level Intro.

If you want to get started quickly and learn how to build on top of Cosmos SDK, visit Cosmos SDK Tutorials. You can also fork the tutorial's repository to get started building your own Cosmos SDK application.

For more information, see the Cosmos SDK Documentation.

Cosmos Hub Mainnet

The Cosmos Hub application, gaia, has moved to its own cosmos/gaia repository. Go there to join the Cosmos Hub mainnet and more.

Inter-Blockchain Communication (IBC)

The IBC module for the Cosmos SDK has moved to its own cosmos/ibc-go repository. Go there to build and integrate with the IBC module.

Starport

Starport is the all-in-one platform to build, launch, and maintain any crypto application on a sovereign and secured blockchain. If you are building a new app or a new module, use Starport to get started and speed up development.
