# Rewards Layer

The rewards layer implements an economic model to incentivize validator participation and maintain node network security.

Reward distribution mechanism:

The reward distribution incorporates a time-decay factor and a task difficulty multiplier:

$$
R(v,t)=
∑
u∈V
t
​

​
W(u,t)
W(v,t)
​
×R
t
​
×D(t)×e
−λ(t
c
​
−t
s
​
)
$$

*where:*

* R(v,t) is the reward for validator v for task t
* W(v,t) is the weight of validator v for task t
* Vt is the set of validators that participated in task t
* Rt is the base reward for task t
* D(t) is the difficulty multiplier for task t
* λ is the time decay constant
* tc​ is the current time
* ts is the task submission time

Validator weight calculation:

The validator weight is a function of performance, availability, and stake:

$$
W(v,t)=P(v)
α
×A(v)
β
×S(v)
γ
×(1+I(v,t))
$$

*where:*

* P(v) is the performance score of validator v
* A(v) is the availability of validator v
* S(v) is the stake of validator v
* I(v,t) is an innovation factor for new solutions proposed by v for task t
* α, β and γ are adjustable parameters to fine-tune the importance of each factor
