# Achievements
Our Alliance Mining Program system provides an achievement mechanism based on the number of successful referrals a user generates. Upon reaching specific referral milestones, users will receive badge NFTs as certificates.
**Important note**
{% hint style="info" %}
To achieve a certain referral ranking, the valid referral number is based on the number of individuals referred who have upgraded their accounts to VIP 1 or higher (check it out at [Account Upgrade](/alliance-mining-program/user-profile-alliance-center/upgrade-account.md)).
{% endhint %}
> *E.g.*
>
> *If 100 users have been referred, but only 30 of them have upgraded their accounts to VIP 1 or higher, then the valid referral count for upgrading status would be **30**.*
{% hint style="info" %}
* BoE NFT will reward you with a [bonus](/eternals-core/eternals-space/missions.md#mission-bonus) as Space Stones in special missions.
* After importing BoE to an account, it will take **24 hours** to start applying the bonus.
{% endhint %}
> E.g.
>
> *User A applied BoE NFT to his account at 9 AM -> A's account will start counting the BoE's bonus at 9 AM on the following day.*
**There are five distinct levels of achievement as below:**
* **Collection Name:** Beacon of Eternarians
* **Symbol:** BOE
* **Contract:** TBU
| Level | Name | Referrals | Ref Tier | In-game Reward (bonus Space Stones) |
