# Mining and rewards

> **In short** 8 hour sessions at a speed you know in advance. Base speed starts at 2 KIN per hour and halves every 150 million mined; streaks, friends, a trust circle and a welcome boost multiply it.

Mining in Kin ID is simple on purpose: you always know your speed before a session starts, and you get exactly that when it ends. Mining uses no battery or computing power; the phone only starts and claims sessions.

## A session

Tap start and a session runs for **8 hours**. The speed is fixed when it starts and shown in KIN per hour. When the session ends, the $KIN is paid to your balance.

## Your speed

Speed is the base speed multiplied by four boosts:

**Speed = base speed × mining days × team × welcome × trust circle**

### Base speed and halvings

The base speed is the same for everyone. It starts at **2 KIN per hour** and **halves each time 150 million KIN has been mined**, like Bitcoin's halvings. Early members earn faster, and the mining share can never be overrun.

| Mined so far | Base speed |
| --- | --- |
| 0 to 150 million | 2 KIN per hour |
| 150 to 300 million | 1 KIN per hour |
| 300 to 450 million | 0.5 KIN per hour |
| 450 to 600 million | 0.25 KIN per hour |
| Every further 150 million | Halves again |

### Mining days

Mining on days in a row unlocks a higher multiplier, kept for as long as the streak lasts:

| Days in a row | Multiplier |
| --- | --- |
| 1 | ×1.2 |
| 3 | ×1.5 |
| 7 | ×2 |
| 14 | ×3 |
| 30 | ×5 |

### Team

Each friend you invited who is mining when you start a session lifts your speed. See [Invites and teams](./invites) for the full table, from ×2 with one friend to ×150 with a thousand.

### Welcome

New members mine **×2 for their first 3 days**.

### Trust circle

You can vouch for up to 5 friends you know are real people. Each of them who mined in the last 24 hours adds 10% to your speed, when you start a session:

| Members of your circle who mined in the last 24 hours | Multiplier |
| --- | --- |
| 0 | ×1 |
| 1 | ×1.1 |
| 2 | ×1.2 |
| 3 | ×1.3 |
| 4 | ×1.4 |
| 5 | ×1.5 |

You can only vouch for friends, and you can change your circle at any time. Your profile shows how many people vouch for you. See [Invites and teams](./invites).

## An example

At today's base speed of 2 KIN per hour, a member on a 7 day streak (×2) with 3 friends mining (×3) mines at **12 KIN per hour**, or **96 KIN per 8 hour session**.

## Daily rewards

Besides mining, Kin ID pays rewards from the same share:

- **Joining:** a 100 $KIN welcome bonus when an account is created.
- **Daily check in:** 10 to 60 $KIN a day, growing over the week, with streak bonuses from 25 $KIN at 2 days up to 50,000 $KIN at 365 days.
- **Tasks:** daily ones, such as watching a short video or visiting kinidentity.com, pay 10 $KIN each; one time ones, such as following Kin on X, Telegram, Instagram, TikTok or YouTube, pay 75 to 100 $KIN. Sharing your invite link can be a task too.
- **Learn and earn:** short quizzes about Kin, each with a whitepaper chapter to read first, pay 100 to 150 $KIN when every answer is right.
- **Weekly team goals:** you and the friends you invited mine together from Monday to Sunday, and reaching 500, 2,000 and 5,000 KIN pays 150, 600 and 1,500 $KIN. See [Invites and teams](./invites).
- **Challenges and rain:** $KIN shared in rooms, sometimes sponsored by partners.

## Changing the numbers

The Kin team can adjust session length, multipliers and rewards as the network grows, for example to keep the mining share lasting. Changes only apply to sessions that start after them, and will be announced in the app and on kinidentity.com. The total supply and the shares cannot be changed.
