🗳️ Voting System – Cost Estimate
Decentralized blockchain voting platform | Flutter + Serverpod + Cryptounit
📌 Executive Summary (for investors / clients)
MVP / Pilot version (real testing with up to 1,000 users): €40,000 – 70,000
Beta version (ready for party / HOA / municipality pilot): €70,000 – 120,000
Production (security, audit, scaling, explorer, auditor API): €120,000 – 200,000+
🧱 What is included? (detailed breakdown)
| Component | Description | Estimated cost (€ net) |
|---|
| 1. Base platform (existing prototype) |
Flutter (mobile) + Serverpod (backend). Auth, roles (member/operator/journalist/auditor), PostgreSQL + Redis + Elixir for real-time. |
15,000 – 25,000 |
| 2. Blockchain core (most expensive) |
Smart contracts in C++ (EOSIO): voting, delegation, Community factory. Integration with Cryptounit (RPC, signatures, gas paid by organizer). Minimal working explorer. |
20,000 – 50,000 |
| 3. Pilot scenarios (turnkey) |
Invitations + automatic wallet creation, delegation, organizer/operator dashboard, CSV/PDF export, result viewer with explorer links. |
15,000 – 30,000 |
| 4. Security & audit |
Redundant RPC providers, role separation (organizer vs admin vs auditor), smart contract audit, security documentation + testing. |
10,000 – 20,000 |
| 5. Optional (if needed) |
• Branded blockchain explorer — €5,000 – 10,000
• eID / government system integration — €10,000 – 20,000
• Zero-Knowledge Proofs (ZKP) — €30,000+

📊 Total cost formula
MVP (demo with real votes): €40,000
Beta (party / HOA / municipality): €60,000 – 80,000
Production (ready to scale): €100,000 – 150,000
All figures — turnkey development, excluding monthly support.
⚠️ Why not cheaper?
- This is not a Telegram poll — it's a legally significant voting system
- The blockchain part cannot be done cheaply and securely at the same time
- Role separation (5 groups: organizer / operator / member / journalist / auditor) is ≈80% of architectural work
- Smart contract audit alone costs €5,000 – 10,000 even without development
- This is a political / municipal / enterprise-grade product, not a simple website
✅ What you get in production version
- 📱 Mobile apps (iOS + Android) and Web portal
- 🔐 Immutable votes on Cryptounit blockchain
- 👤 Cold wallets — private keys never leave user devices
- 🎯 Delegation (transfer voting power to trusted members)
- 🏘️ Community as a service (create unlimited polls inside your organization)
- 📊 Blockchain explorer for full transparency and audit
- 💰 Gas paid by organizer — voters never pay fees
- 📁 CSV/PDF exports with cryptographic proofs
📊 Comparison: Our system vs alternatives
| Criteria | Google Forms / SurveyMonkey | Our blockchain system |
|---|
| Results can be altered? | ✅ Yes (admin can change) | ❌ No (immutable blockchain) |
| Anyone can verify results? | ❌ No | ✅ Yes (blockchain explorer) |
| Voter anonymity | ❌ No (tracks identity) | ✅ Yes (pseudonymous wallets) |
| Delegation support | ❌ No | ✅ Yes |
| Gas fees for voters | N/A | ❌ None (paid by organizer) |

🎯 Resume
- This is an institutional-grade product, not a weekend hackathon project
- Smart contract audit alone costs €5K–€10K in the open market
- Competitors (Snapshot, Aragon, Agora) start at €50K+ for similar setups
- We are offering full stack — mobile + web + blockchain + explorer + audit tools
