TOS Energy Model (TEM)

The TOS Energy Model allows users to stake TOS tokens to generate “Energy” that can be used for gas-free transactions, providing predictable costs and eliminating the need to hold gas for every operation.

How It Works

1. Stake TOS tokens (lock period: 7-365 days)
2. Generate Energy based on stake amount and duration
3. Use Energy instead of TOS for transaction fees
4. Energy regenerates over time while staked

Benefits

For Users

• No gas fees for everyday transactions
• Predictable costs - stake once, transact freely
• Earn while staking - tokens remain yours, just locked

For Projects

• Sponsor user gas - stake on behalf of users
• Reduce friction - no “need gas” popups for users
• Budget predictability - fixed staking cost vs variable gas

For Network

• Reduced circulating supply - staked tokens are locked
• Long-term alignment - stakers committed to network success
• Spam prevention - still requires stake commitment

Energy Generation

Energy is generated based on:

• Stake amount: More TOS = More energy
• Lock duration: Longer lock = Higher multiplier
• Time staked: Energy accumulates over time

Lock Period Multipliers

Transaction Types

Pay with TOS (Default)

let tx = Transaction {
    fee_type: FeeType::TOS,
    gas_limit: 10_000,
    // Fee paid from TOS balance
};

Pay with Energy (Gas-Free)

let tx = Transaction {
    fee_type: FeeType::Energy,
    // No gas_limit needed, uses Energy
};

Supported Operations

Staking Operations

Freeze TOS (Stake)

# CLI
tos_wallet freeze_tos --amount 1000 --days 30

// JavaScript SDK
await tos.freezeTos({
    amount: 1000_00000000, // 1000 TOS
    lockDays: 30
});

Unfreeze TOS (Unstake)

# CLI (after lock period ends)
tos_wallet unfreeze_tos --amount 1000

// JavaScript SDK (after lock period)
await tos.unfreezeTos({
    amount: 1000_00000000
});

Check Energy Balance

tos_wallet get_energy

const energy = await tos.getEnergy(address);
console.log(`Available Energy: ${energy.available}`);
console.log(`Daily Generation: ${energy.dailyGeneration}`);

Energy Regeneration

Energy regenerates continuously based on your stake:

Energy per second = (stake_amount × multiplier) / 86400

Example:
1000 TOS staked for 30 days (1.5x multiplier)
= 1000 × 1.5 / 86400
= 0.0174 Energy/second
= 1,500 Energy/day

Maximum Energy Cap

Energy caps at 30 days worth of generation:

Max Energy = daily_generation × 30

Example:
Daily: 1,500 Energy
Max: 45,000 Energy

Use Cases

Individual User

Stake: 1,000 TOS for 30 days
Daily Energy: 1,500

This covers approximately:
- 1 transfer/day (1,000 energy)
- OR 1 contract call every 3 days (5,000 energy)

Active Trader

Stake: 10,000 TOS for 90 days
Daily Energy: 20,000

This covers approximately:
- 20 transfers/day
- OR 4 DEX swaps/day
- OR combination of both

Project Sponsorship

Project stakes: 100,000 TOS for 365 days
Daily Energy: 300,000

This sponsors approximately:
- 300 user transfers/day
- OR 60 contract calls/day

Fee Type Selection

Transactions can specify which fee method to use:

pub enum FeeType {
    /// Pay with TOS balance (default)
    TOS = 0,
 
    /// Pay with Energy (gas-free)
    Energy = 1,
 
    /// Pay with UNO balance (for privacy transactions)
    UNO = 2,
}

Automatic Fallback

If Energy is insufficient, transaction fails with clear error:

Error::InsufficientEnergy {
    required: 5000,
    available: 3000,
}

User can then retry with FeeType::TOS or wait for Energy regeneration.

Delegation (Coming Soon)

Users will be able to delegate their Energy to others:

// Delegate Energy to another address
delegate_energy(recipient, amount_per_day);
 
// Revoke delegation
revoke_energy_delegation(recipient);

This enables:

• Projects sponsoring user transactions
• Services providing gas-free experience
• Parents funding children’s wallets

Economic Impact

For Token Price

• Reduces circulating supply
• Creates natural demand for TOS
• Long-term holder incentives

For Network

• Sustainable fee model
• Spam resistance maintained
• Predictable network economics

Comparison with Other Models

Summary

The TOS Energy Model provides:

• Gas-free transactions through staking
• Flexible lock periods from 7 to 365 days
• Higher rewards for longer commitments
• Continuous regeneration of Energy
• Project sponsorship capability

This creates a sustainable economic model where active network participants can transact freely while maintaining network security through stake requirements.
