## Funding Strategy

### Option 1: Venture Capital
- Raise $1.5M - $2M seed round
- Give up 20-30% equity
- Pros: Fast funding, network/connections
- Cons: Investor pressure, loss of control

### Option 2: Grants & Donations
- Apply for blockchain grants (Ethereum Foundation, etc.)
- Open-source community donations (GitHub Sponsors, Gitcoin)
- Pros: No equity dilution, community-aligned
- Cons: Slower, uncertain amounts

### Option 3: Fair Launch with Treasury
- 2% of genesis mining goes to treasury (20,000 ONC)
- Treasury funds development (if ONC reaches $50, that's $1M)
- Pros: Aligned with fair launch ethos
- Cons: Chicken-and-egg (need value first)

### Option 4: Hybrid
- Small initial funding ($200K-$500K from angel investors or grants)
- Bootstrap to testnet
- Raise larger round after testnet success
- Use genesis treasury for long-term sustainability

**Recommended**: Option 4 (Hybrid approach)
