Delegators (Stakers)
What Are Delegators?
Delegators are all stakers who delegate their assets to validators, financially backing them to secure Mosaic Chain. By risking their capital (slashing) to support validators, delegators earn staking rewards in return.
Two types of delegators participate in Mosaic Chain's DPoS consensus:
1. MOS Coin Holders
Delegate MOS coins to validators
No NFT required to participate
Flexible staking across multiple validators
2. Delegator NFT Holders
Delegate Delegator NFTs to validators
Each NFT stakes to one validator
Can combine with MOS coin staking
The Delegator's Role
Delegators are passive participants in Mosaic Chain, contributing to blockchain health and security indirectly. Unlike validators, delegators don't run nodes or maintain infrastructure—but they play a critical role in the network's economic security.
Two primary responsibilities:
1. Select responsible validators
Research commission rates, uptime, and reputation
Perform due diligence on validator performance
Monitor slashing history and track record
2. Delegate assets strategically
Stake MOS coins and/or Delegator NFTs
Diversify across multiple validators to minimize risk
Balance reward potential with slashing risk
Key considerations:
✅ No technical requirements - No nodes, no uptime, no infrastructure
✅ Earn staking rewards - Passive income from validator performance
⚠️ Slashing risk - If your validator is slashed, you lose 0.1% of your stake
⚠️ Reward dependency - Your earnings depend on validator performance and commission rates
Active Monitoring Recommended
While delegators are passive participants, regular monitoring is advisable:
Check validator performance weekly or monthly
Monitor uptime, slashing events, and commission changes
Be prepared to switch validators if performance declines
Rebalance your portfolio based on changing conditions
Remember: Your validator's performance directly impacts your rewards and your capital. Passive participation doesn't mean "set and forget"—it means staying informed without running infrastructure.
Requirements to Become a Delegator
To participate as a Delegator, you need:
MOS coins - At least 50 MOS (global minimum)
Choose a DPoS validator - Research validators based on commission, uptime, and reputation
Create a staking contract - Stake your MOS coins (and/or Delegator NFT if you have one)
Wait for the end of the minimum staking period - Global minimum: 28 days / 672 sessions
Optional:
Delegator NFT - Allows you to stake the NFT's nominal value in addition to MOS coins
What You Can Stake
1. MOS Coins
Stake MOS coins to any DPoS validator
Everyone can stake MOS coins (no NFT required)
Minimum: 50 MOS per staking contract
Can split your MOS across multiple validators
2. Delegator NFTs (Optional)
Own a Delegator NFT to stake its nominal value
Each Delegator NFT can be staked to one validator
NFT nominal value is staked in addition to any MOS coins you stake
Key insight: You don't need a Delegator NFT to participate. Anyone with MOS coins can start staking immediately.
Delegator NFTs (Optional)
Delegator NFTs are optional assets that allow you to stake their nominal value to validators.
Key features:
Nominal value - The NFT's nominal value is your stake (subject to slashing)
One validator per NFT - Each Delegator NFT can only be staked to one validator at a time
Multiple NFTs for diversification - To stake with multiple validators, you need multiple Delegator NFTs
Transferable - Can be sold or transferred to another account
Binding required - Must be bound when staked to a validator
Expiration period - Delegator NFTs have approximately 12-24 months of validity from binding
Time-limited staking - Plan your staking strategy around the NFT's expiration date
Do you need a Delegator NFT?
❌ No - You can stake MOS coins without any NFT
✅ Yes, if you want to stake the NFT's nominal value in addition to MOS coins
Important considerations:
Monitor your NFT's expiration date closely
Unstake and rebind (or acquire a new NFT) before expiration
Expired NFTs cannot be used for staking
Plan your staking periods within the validity window
Rewards
Delegators earn a share of the validators' block rewards, minus the validator's commission.
How Rewards Are Calculated
Your rewards depend on:
Your stake - More stake = more rewards
Total stake - Your share is proportional to your stake vs. total
Validator's commission - Lower commission = more rewards for you
Validator's activity - Only active validators earn rewards (200 per session)
Formula:
Your rewards = (Your stake / Total stake) × Session rewards × (1 - Commission rate)Reward Distribution
Rewards are distributed at the end of each session (1 hour ≈ 600 blocks)
Only when your validator is active (selected by the subset algorithm)
If your validator is in waiting or chilled status, you earn nothing in that session
Reward Sources
Validators earn from multiple sources, and delegators share in these rewards:
Block Rewards
Newly minted MOS coins (expansion formula)
80% distributed to validators (20% to Treasury)
You earn a proportional share minus commission
Slashing Risk
Delegators share in both the rewards and the risks of their chosen validators.
What Gets Slashed
If your validator is slashed:
Your staked MOS coins - 0.1% per slashing event
Your staked Delegator NFT nominal value - 0.1% per slashing event
