Fee Model & Economics

Omne’s economic model prioritises accessibility over revenue. Fees exist to prevent spam, not to generate income.

Microscopic fees

Denomination

Gas price is denominated in Quar. The default gas price is 1000 Quar.

import { toQuar, fromQuar, formatBalance } from '@omne/sdk'
 
toQuar('1.5')                               // "1500000000000000000"
fromQuar('1500000000000000000')             // "1.5"
formatBalance('1500000000000000000')        // "1.500000000000000000 OMC"

Anti-spam (non-fee controls)

Rather than raising fees to discourage spam, Omne uses dedicated controls:

Rate limiting

• Per-peer: Each P2P peer has bandwidth and message rate limits
• Per-account: Transaction submission rate limited per sender address
• Per-IP: RPC endpoint rate limiting with configurable quotas

Quality of Service

• Stake-weighted QoS: Validator messages prioritised by stake
• Message priority: Consensus messages survive overload; low-priority traffic is shed first

Circuit breakers

• Mempool flood protection: Backpressure when mempool exceeds threshold
• RPC overload shedding: HTTP 429 responses with X-RateLimit-* headers

API key quotas

Operator-provisioned API keys can carry per-key rate limits:

{
  "key": "partner-token",
  "profile": "observer",
  "quota": {
    "requests_per_minute": 120,
    "burst": 12
  }
}

Fee recycling

OMC is a $1 soft-pegged commerce token. Aggressively burning fees (as Ethereum does with ETH) would create deflationary pressure that breaks this peg. Instead, Omne uses fee recycling:

The EIP-1559-style base fee adjustment still applies (fees rise under congestion, fall under low utilisation), but the destination is recycling rather than aggressive burning. This keeps OMC supply approximately neutral.

The split is defined by ANTI_SPAM_BURN_RATE = 0.08 and recycled fees are credited to VALIDATOR_FEE_POOL_ACCOUNT.

Validator rewards

Validators earn rewards from:

• Block production fees — share of transaction fees in blocks they produce
• Performance bonuses — based on uptime and attestation participation
• Longevity bonuses — for sustained participation in consensus

const rewards = await client.calculateValidatorRewards('omne1validator...')
 
rewards.baseReward        // base fee share
rewards.performanceBonus  // uptime bonus
rewards.longevityBonus    // participation duration bonus
rewards.totalReward       // sum

Staking

Validators stake OGT (Omne Governance Token) to participate in consensus:

The optimal stake can be estimated via the SDK:

const optimal = await client.estimateOptimalStake(0.95)
// { recommendedStake, minimumRequired, expectedReturns, riskFactors }

Slashing

Validators can be slashed for:

• Double signing — signing conflicting blocks at the same height
• Extended downtime — failing to participate in consensus for an extended period
• Malicious attestation — submitting fraudulent attestation data

Slashing outcomes are routed to either a burn address or the treasury, depending on the offense.
