# Mint names

The syntax below applies to all SNS namespaces, for example `.sats` `.ord` `.gm` and so on, plus all future namespaces. 

New names can be minted (inscribed for the first time) as ordinals with only a Bitcoin transaction. This process is open to anyone that can inscribe. 

## Registering names

### Simple registration

To register a new name within the Sats Name System simply inscribe an ordinal containing your desired name. Here is an [example](https://ordinals.com/inscription/04a53ecaf63216850635efe16e6efbc8813dce60fac2af642a66c9d46d2a1972i0). 

```
satoshi.sats
```

### Advanced registration

Advanced registration allows users to add additional data to a name using JSON5 syntax. The format is optional for registration. 

```json
{ 
  "p": "sns",
  "op": "reg",
  "name": "satoshi.sats",
  "avatar": "7f9c06b712c5b60c0b66868c69568b2d198533553c347cd732fc3c87e62efe86i0",
  "rev": "bc1psvggtp7mzr3lu8x5vrycqjqqkk5e7urtu2axjvwejea0ctjfdl3qqrctsf",
  "relay": "85b10531435304cbe47d268106b58b57a4416c76573d4b50fa544432597ad670i0"
}
```

{% hint style="warning" %}
Updating names: Avatar, Relay, and Reverse Resolution (rev) will have update operations in the future. There are some complexities related to making updates safe and reliable that will require new inscription tools. Once those are widely available and tested, we will release the syntax!
