A rough specification of the script:

Below you can find specification of three different areas:

1.      Guest area / frontpage

Content of the other subpages should be configured and loaded from database

1.1.    Homepage: 

1.1.1.  show sponsor / default referrer

1.1.2.  total donations amount

1.1.3.  top earners (period of time configurable)

1.1.4.  top recruiters (period of time configurable)

1.1.5.  top countries (period of time configurable)

1.2.    Login page:

Form:

1.2.1.  Username

1.2.2.  Password

1.2.3.  remember me

1.2.4.  captcha (configurable from admin panel)

1.3.    Register page:

Option to block registration until some date. Form:

1.3.1.  show sponsor / default referrer

1.3.2.  Username

1.3.3.  Email

1.3.4.  Password

1.3.5.  Country

1.3.6.  security question and answer

1.3.7.  link to tos

1.3.8.  other fields configurable from Admin panel

1.3.9.  captcha (configurable from admin panel)

1.4.    Password recovery page:

1.4.1.  Email

1.4.2.  captcha (configurable from admin panel)

2.      Member area

2.1.    Dashboard

There should be statistic showing in header total members and total donations (same as on homepage), then user profile - join date, last login date, avatar, amount/value of donations sent/received. Additionally summary of user's ref network is required.

2.2.    Finances

There should be ability to manage BTC wallet (add/edit).

The most important option is to Upgrade the account. By default each account is created for 48h (configurable), then is removed from system, unless user will donate his upline on time. User needs to know his upline BTC address, makes a donation, then provides transaction id for verification. Script verifies if amount and recipient account are correct.

Matrix size should be configurable from admin panel. If your upline has enough users referred, then newly registered user is placed at first possible spot in the tree of original referrer. There should be 2 algorithms for assigning to choose: left to right or weakest leg.

Users can only donate upgraded uplines.

Level 1: 0.027 BTC

Level 2: 0.045 BTC

Level 3: 0.090 BTC

Level 4: 0.180 BTC

Level 5: 0.900 BTC

Level 6: 1.800 BTC

User on Level 1 sends donation to level 1 upline and receives donations from downlines on level 1.

User on Level 2 sends donation to level 2 upline and receives donations from downlines on level 2.

and so on...

In matrix width 2, you need to activate your account by donating an upline with 0.027 BTC.

On the first level you can receive 2 donations of 0.027 BTC from non-active downlines and you send 0.045 BTC to upline to gain level 2.

Second level upgrade allows to receive 4 donations of 0.045 BTC from level 1 downlines and requires to donate 0.09 BTC to level 3 upline. 

On third level you can receive 0.09 BTC from 8 downlines on level 2, but need to donate 0.18 BTC to get to level 4.

On level 4 you can receive 0.18 BTC from 16 downlines on level 3, you need to donate 0.9 BTC to upline on level 5.

On level 5 you can receive 0.9 BTC from 32 downlines on level 4, you need to donate 1.8 BTC to upline on level 6.

On level 6 you can receive 1.8 BTC from 64 downlines.

To keep your upgrades active and be able to receive donations in the following month, you need to pay subscription for each upgrade once per 30 days.

System needs to manage all users properly. Inactive accounts to delete cause a need to rebuild the tree in a fair way. It also should prevent the situation, where one user has more downlines than width of the matrix is.

For each donation user receives ad points (amount configurable). You can also see list of pending, completed and missed donations.
