{:.no_toc}
You can use the blockstack.js library to create and register an Blockstack username on the Stacks blockchain. This section describes the `Profile` object and contains the following topics:

## About profiles
Profile data is stored using Gaia on the user's selected storage provider. An example of a `profile.json` file URL using Blockstack provided storage:
```
https://gaia.blockstack.org/hub/1EeZtGNdFrVB2AgLFsZbyBCF7UTZcEWhHk/profile.json
```
Follow these steps to create and register a profile for a Blockstack username (`identifier`):
1. Create a JSON profile object
2. Split up the profile into tokens, sign the tokens, and put them in a token file
3. Create a zone file that points to the web location of the profile token file
```js
"account": [
{
"@type": "Account",
"service": "twitter",
"identifier": "naval",
"proofType": "http",
"proofUrl": "https://twitter.com/naval/status/12345678901234567890"
}
]
```
## Create a profile
```es6
const profileOfNaval = {
"@context": "http://schema.org/",
"@type": "Person",
"name": "Naval Ravikant",
"description": "Co-founder of AngelList"
}
```
## Sign a profile as a single token
```es6
import { makeECPrivateKey, wrapProfileToken, Person } from 'blockstack'
const privateKey = makeECPrivateKey()
const person = new Person(profileOfNaval)
const token = person.toToken(privateKey)
const tokenFile = [wrapProfileToken(token)]
```
## Verify an individual token
```js
import { verifyProfileToken } from 'blockstack'
try {
const decodedToken = verifyProfileToken(tokenFile[0].token, publicKey)
} catch(e) {
console.log(e)
}
```
## Recover a profile from a token file
```js
const recoveredProfile = Person.fromToken(tokenFile, publicKey)
```
## Validate profile schema
```js
const validationResults = Person.validateSchema(recoveredProfile)
```
