# Reserved name

Existing TLDs and over 100,000 Alexa websites are reserved on the Handshake blockchain. Upon removing collisions, generic, and exclusions (e.g. 1 or 2 character names), approximately 80,000 names remain. Using the root key and DNSSEC, domain owners can cryptographically prove ownership to the Handshake blockchain to claim names. 100,000 was chosen as a number which the ownership is clear and has already gone through policy and process.

## Existing TLDs
All existing [ICANN TLDs](https://github.com/handshake-org/hs-names/blob/master/names/tld.json) ([ccTLDs](https://github.com/handshake-org/hs-names/blob/master/names/cctld.json), [gTLDS](https://github.com/handshake-org/hs-names/blob/master/names/gtld.json), [rTLD](https://github.com/handshake-org/hs-names/blob/master/names/rtld.json)) are reserved and can't be opened at auction.

## Alexa
The Handshake blockchain pre-reserves the [top ~100,000 domain names](https://github.com/handshake-org/hs-names/blob/master/names/alexa.json) from the Alexa top 1 million domain names. Since the Handshake blockchain only thinks in terms of top-level domains, existing domains on the Alexa top 1 million are "converted" to TLDs.

For example:

`google.com` -> `google`
`bbc.co.uk` -> `bbc`

### Rules
In order to have your domain pre-reserved, there are a few rules implemented in generate.js that it must conform to:

- The domain's deepest subdomain must not be in the blacklist.
- The domain's deepest subdomain must not be a pseudo-TLD for an existing naming project.
- The domain's deepest subdomain must not be a trademarked name.
- The domain must not collide with an existing top-level domain in ICANN's root zone, as all existing TLDs are also pre-reserved. For example, `google.com` would lose to `google`.
- The domain must not collide with a higher-ranked domain. For example, `google.co.uk` would lose to `google.com`. Only the owner of the higher-ranked domain is able to redeem it.
- The domain must not be deeply nested. `bbc.co.uk` will work, but `jeffs-blog.wordpress.com` will not.
- The domain must abide by Handshake policy standards (no leading or trailing hyphens or underscores).
- The domain must not be a single letter.
- If the domain is ranked lower than 50,000, the domain must not be two letters.
- If the domain is ranked lower than 50,000, the domain must not be an [English word](https://raw.githubusercontent.com/handshake-org/hs-names/master/names/words.json).

## Blacklist
The following list is permanently reserved:

- `example`
- `invalid`
- `local`
- `localhost`
- `test`
