Staking Guide

Overview

Staking in ComputeChain allows you to: - Become a validator - produce blocks, earn rewards - Delegate to validators - earn passive income - Participate in consensus - secure the network

Staking (Become Validator)

Requirements

  • Minimum stake:
  • Devnet: 1,000 CPC
  • Mainnet: 100,000 CPC
  • Node: Must run a validator node
  • Uptime: 75% minimum to stay active

Stake Tokens

./cpc-cli tx stake <AMOUNT> --from <KEY_NAME>

Example:

# Stake 500 CPC
./cpc-cli tx stake 500 --from mykey

What happens: 1. Tokens locked from your balance 2. Validator created with cpcvalcons1... address 3. Activated in next epoch (after 100 blocks)

Unstake Tokens

./cpc-cli tx unstake <AMOUNT> --from <KEY_NAME>

Important: - Can unstake partially or fully - Unbonding period: - Devnet: 100 blocks (~16 minutes) - Mainnet: 21 days - Penalty if jailed: 10% slashed when unstaking while jailed - Full unstake → validator deactivated - Tokens automatically returned after unbonding period

Delegation

Delegate to Validator

Earn passive rewards by delegating to validators.

Limits: - Minimum delegation: 100 CPC - Max validators per delegator: 10 - Max validator power: 20% of total voting power

./cpc-cli tx delegate <VALIDATOR_ADDRESS> <AMOUNT> --from <KEY_NAME>

Example:

# Delegate 100 CPC to validator
./cpc-cli tx delegate cpcvalcons1abc... 100 --from mykey

Check Delegations

./cpc-cli query delegations <YOUR_ADDRESS>

Output:

Delegator: cpc1abc...
Total Delegated: 100.0 CPC

Validator                Amount    Commission  Name
------------------------------------------------------
cpcvalcons1xyz...        60.0      10.0%       Validator A
cpcvalcons1def...        40.0      5.0%        Validator B

Undelegate

./cpc-cli tx undelegate <VALIDATOR_ADDRESS> <AMOUNT> --from <KEY_NAME>

Important: - Unbonding period: Same as validators (21 days mainnet / 100 blocks devnet) - No penalty: Delegators are not penalized for undelegating - Slashing risk: If validator is slashed, delegators lose 5% too - Tokens automatically returned after unbonding period

Rewards

How Rewards Work

Block Reward: 10 CPC per block (halves every 1M blocks)

Block Reward Split: - 70% → Validator Pool (block producer) - 30% → Miner Pool (PoC workers, currently burned until Phase 2A)

Transaction Fees Split: - 90% → Validator (block producer) - 10% → Treasury (community pool)

Validator Reward Distribution: 1. Validator has delegations: - Validator receives commission (0-20%, configurable) - Delegators share remaining amount proportionally - Any dust from integer division is burned

  1. No delegations:
  2. Validator receives 100% of their pool

Example:

Block Reward: 10 CPC
Validator Pool (70%): 7 CPC
Validator Commission: 10%
Total Delegated: 100 CPC

→ Validator: 0.7 CPC (commission)
→ Delegator A (60 CPC): 3.78 CPC
→ Delegator B (40 CPC): 2.52 CPC

Check Rewards

./cpc-cli query rewards <YOUR_ADDRESS>

Output:

Delegator: cpc1abc...
Total Rewards: 125.5 CPC

Epoch    Reward
------------------
0        25.4 CPC
1        24.8 CPC
2        25.1 CPC

Claim Rewards

Rewards are auto-credited to your balance - no manual claim needed!

Commission

For Validators

Set your commission rate (0-20%):

./cpc-cli tx update-validator --commission 0.15 --from mykey

Rules: - Range: 0% - 20% maximum - Cooldown: 7 days between changes - Announce period: 4 hours before change takes effect - Max increase: +5 percentage points per change

Example: 

Day 0: Commission 5%
Day 7: Announce change to 10% → Effective in 4 hours
Day 14: Can change again (cooldown passed)

Default: 10% Recommended: 5-15%

For Delegators

Choose validators with: - ✅ Low commission (more rewards for you) - ✅ High uptime (consistent rewards) - ✅ Good reputation

Protection: During the 4-hour announce period, delegators can undelegate without penalty (just the normal 21-day unbonding period).

Tips

For Validators: - Keep uptime >75% to avoid jailing - Set reasonable commission (5-15%) - Update metadata (name, website) for visibility

For Delegators: - Diversify across multiple validators - Check validator uptime and commission - Monitor rewards regularly
