# Polkadot Delegation Guide

[Polkadot](https://polkadot.network/) is a network of interoperable but independent blockchains that share security.

You can learn more about the protocol in our [Guide to Polkadot](https://www.coinbase.com/cloud/discover/protocol-guides/guide-to-polkadot).

| Protocol Parameter                  | Value          |
| :---------------------------------- | :------------- |
| Minimum tokens to stake             | \~2 DOT        |
| Waiting period to change nomination | Up to 24 hours |
| Unbonding period                    | 28 days        |
| Service fee                         | 8% of rewards  |

There are two different types of accounts for managing your delegation funds in Polkadot:

* A **controller** makes staking decisions, such as nominating and bonding funds, but does not have direct control over the funds themselves.
* A **stash** directly controls the funds, and designates a controller to be used to make staking decisions.

The stash/controller system maintains secure control over one's funds while still enabling users to make and change staking decisions easily. You must import your stash to the Polkadot UI in order to stake your funds, including nominating them to the Coinbase public validator.

You can stake to Coinbase's community validators by joining our Nomination Pool.

  The Coinbase Pool nominates these validator addresses. If staking directly, enter each of the Coinbase validator addresses from the list above.

  The Coinbase pool selects all validators from this list, and joining indicates your willingness to support any of them. The protocol automatically allocates pool stake to a subset of the validators from the nominated list that have been selected to operate and earn rewards each era. As such, selecting all validators increases your opportunities to earn rewards. See the [Polkadot FAQ](/staking/staking-delegation-guides/polkadot/polkadot-faq) to learn more.
