# Rewards
Guide for Claiming Proof-of-Machine Rewards.
### Rewards System
GRIDBOX offers two types of rewards:
1. **Direct Payments**\
When your machine is rented, you receive payment directly from the renter.
2. **Proof of Machine Rewards**\
Inspired by Proof of Work, this system rewards machines simply for being listed. Every Monday, eligible machines receive bonus rewards from the BLOCX project.
* **Eligibility Criteria**:
* Machine must be listed for at least 7 days
* Once eligible, the **Rewards** section unlocks and weekly bonuses begin
### Rewards Logic & Formula
#### **Rewards payout logic**
* 80% of the reward pool goes to GPUs.
* 20% goes to CPUs.
* Within each pool, rewards are distributed proportionally based on each machine’s effective score.
Process we follow to make sure rewards are fair and balanced:
1. **We start by calculating the HPI (Hashpower Index) for every machine.**
* Each GPU and CPU gets a performance score based on its hardware specs.
* This gives us a baseline measure of how powerful each device really is.
2. **We then factor in uptime over a 7-day period.**
* A machine that’s online and contributing consistently all week scores higher.
* If a machine is only active part-time, its effective score is reduced.
3. **We compare each machine’s score against the rest of the network.**
* This shows us what percentage of the total computing power each contributor is providing.
### **General Hashrate with Hardware Specs**
**For GPUs**
* CUDA cores / Stream processors
* Core clock speed (GHz)
* Memory bandwidth (GB/s)
* VRAM size (GB)
* TDP (power draw)
**Hashpower Index (HPI) Formula (GPU):**
**For CPUs**
* Number of cores and threads
* Base and boost clock speed (GHz)
* Cache size (L3 especially)
* Instruction set support (e.g., AVX2, AVX-512)
**Hashpower Index (HPI) Formula (CPU):**
When visiting GRIDBOX and adding a machine, you must first wait 7 days to unlock rewards section. This ensures that rewards are given only to those who truly contribute to the GRIDBOX and BLOCX. ecosystem.\

After 7 days, the rewards screen becomes available. You’ll be able to claim machine rewards every Monday from that point forward.
