# Nano

Official Website: [nano.org](https://nano.org/)

Nano (XNO), formerly known as RaiBlocks, is a cryptocurrency designed for fast, feeless transactions. Launched in 2015, Nano uses a unique block-lattice architecture where each account has its own blockchain, allowing for instant transaction confirmations. This setup eliminates the need for mining, reducing energy consumption and transaction fees, making it ideal for microtransactions and direct peer-to-peer payments. The consensus mechanism, Open Representative Voting (ORV), ensures security and prevents double-spending without the need for traditional mining or staking processes.

## Addresses

In Cake Wallet's Nano wallet, there is only one address per wallet, which is standard for the Nano ecosystem. Keep in mind that this will have lesser privacy compared to some other assets, where new addresses are automatically generated.

Your Nano address will start with `nano_` followed by a series of alphanumeric characters.

## Seed Format

Cake Wallet uses a 12-word BIP39 seed for new Nano wallets by default. When creating or restoring a wallet, you can use this seed phrase.

Under `Advanced Settings` on the wallet creation screen, the `Seedtype` option lets you pick between:

* **BIP39** — the default. With BIP39 selected you can also set a `Seed phrase length` of **12** (default) or **24** words.
* **Nano** — the standard Nano seed format, for compatibility with other Nano wallets.

{% hint style="info" %}
Your BIP39 seed can be shared with your other Cake Wallet currencies as part of a [wallet group](https://docs.cakewallet.com/features/managing-your-wallet/wallet-groups). A wallet created with the **Nano** seed type cannot join a wallet group.
{% endhint %}

## Fees

Nano transactions are feeless — there is no network fee to send XNO, so you don't need to hold anything extra to cover fees.

Because of this, Nano is the only wallet type in Cake Wallet where the send screen shows no `Fees` row at all.
