## Abstract

|
|
This paper specifies the Staking module of the Cosmos-SDK, which was first
|
|
|
|
|
described in the [Cosmos Whitepaper](https://cosmos.network/about/whitepaper)
|
|
|
|
|
in June 2016.

|
|
|
The module enables Cosmos-SDK based blockchain to support an advanced
|
|
|
|
|
Proof-of-Stake system. In this system, holders of the native staking token of
|

|
|
|
the chain can become validators and can delegate tokens to validators,
|
|
|
|
|
ultimately determining the effective validator set for the system.

This module will be used in the Cosmos Hub, the first Hub in the Cosmos

|
|
|
|
network.
