# Staking Score

Staking and unstaking in the GBM Protocol are instant, with **no bonding or unbonding delays**. 

Your share of any governance-approved reward distribution **is based on your total staking score**, which combines two factors:

### ⏳ 1. Accumulated Score

The **Accumulated Score** rewards loyalty. It increases every second your tokens remain staked and represents your long-term staking contribution.

**Formula:**\
Accumulated Score = Time staked × Tokens staked × Stake Coefficient

**Example:**\
You stake **100 GBM tokens** for **90 days** (7,776,000 seconds) with a **Stake Coefficient of 2**.\
Accumulated Score = 7,776,000 × 100 × 2 = **1,555,200,000 points**

Unstaking stops your score from growing, but your earned points remain intact.\
\
The Stake Coefficient starts at **2** and can be updated by governance.

### ⚡ 2. Instant Score

The **Instant Score** is a **bonus awarded for presence**. It rewards anyone **still staked at the final snapshot**, even if they joined late in the period.

**Formula:**\
Instant Score = Time elapsed × Tokens staked

**Example:**\
You stake **100 GBM tokens** for the **last 10 days** of a **90-day reward period**.\
Time elapsed = 7,776,000 seconds\
Instant Score = 7,776,000 × 100 = **777,600,000**

This ensures that even short-term stakers earn a share for being active when the final snapshot is taken.

### 🧮 Total Score

Your **Total Score** determines your proportional share of the reward pool. 

It combines both **long-term loyalty (Accumulated Score)** and **presence (Instant Score)**.

**Formula:**\
Total Score = (Accumulated Score + Instant Score) ÷ (Time elapsed × (1 + Stake Coefficient))

### 🧠 Example: Comparing Stakers

Imagine a 90-day reward period with a Stake Coefficient of 2.

Alice stakes 100 tokens from day 1 and remains staked for the full 90 days.\
Bob stakes 100 tokens for the final 10 days of the period.

**Alice’s Accumulated Score:**\
7,776,000 × 100 × 2 = **1,555,200,000**

**Bob’s Accumulated Score:**\
864,000 × 100 × 2 = **172,800,000**

**Alice’s Instant Score:**\
7,776,000 × 100 = **777,600,000**

**Bob’s Instant Score:**\
7,776,000 × 100 = **777,600,000**

**Total Score (using full 90-day period = 7,776,000 seconds):**\
Alice → (1,555,200,000 + 777,600,000) ÷ (7,776,000 × 3) = **2,332,800,000** \
Bob → (172,800,000 + 777,600,000) ÷ (7,776,000 × 3) = **950,400,000** 

Alice earns roughly **2.45 times more total points** than Bob because she staked for longer, but Bob still receives a small bonus for being active at the end.

### What This System Ensures

* **Long-term stakers** build higher scores
* **Late joiners** still receive fair credit
* **Unstaking early** stops score growth, but does **not erase** what you’ve earned
