# Contribution Value Algorithm Contract

### <mark style="color:yellow;">Contribution Value Weight Rewards:</mark>

The daily contribution value reward pool is 73% of the total NVB rebase output across the network.

$$
Daily Contribution Value Weight Reward = N \* M / Total Network
$$

$$
Contribution Value M\_total \* Daily Total Network Rebase Output \* 73%
$$

{% hint style="info" %}
Contribution Value = (Sin(Qmax) + ∑Qi)\*3 \
(Qmax: Maximum community computing power; Qi: Community computing power i ; i (i ranges from 1 to n)

(Calculated by multiplying each level by 0.9^(n-1), where n is the number of links from the current node to the original node)

Weight Coefficient N = 0.00003K + 0.7(where K is the staked NVB value of this address, and when K ≥ 10,000, N = 1)
{% endhint %}

### <mark style="color:yellow;">Daily New Contribution Value Rewards:</mark>

Distribute 7% of the total NVB rebase output across the network daily based on the proportion of each account's new contribution value to the total new contribution value across the network.

### <mark style="color:yellow;">Contribution Value Ranking Rewards</mark>

The top 99 accounts in contribution value rankings share 10% of the total NVB rebase output across the network daily, based on weight.

*<mark style="color:orange;">**Contribution Value Reward Release Rules:**</mark>*

* The release rules for contribution value rewards are the same as those for staking rewards.

*<mark style="color:orange;">**Contribution Value Circulation Mechanism:**</mark>*

* When an account's contribution value rewards reach 4 times the rebase amount（Personal initial staking), an equivalent amount of NVB tokens must be destroyed to continue enjoying contribution value dividend rewards.
