Contribution Value Algorithm Contract

Contribution Value Weight Rewards:

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

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

$$Contribution Value M_total * Daily Total Network Rebase Output * 73$$

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)

Daily New Contribution Value Rewards:

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.

Contribution Value Ranking Rewards

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

Contribution Value Reward Release Rules:

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

Contribution Value Circulation Mechanism:

• 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.
