Infrastructure Comparison for Payment Solutions
AppChain vs. Public Network vs. Traditional Ledgers
Choosing the right ledger architecture is critical for payment network performance, cost, and control. This table compares the three primary options for FinTechs and crypto startups.
| Key Factor | AppChain (Custom) | Public Network (e.g., Ethereum) | Traditional Ledger (SQL/NoSQL) |
|---|---|---|---|
Transaction Finality | < 2 seconds | ~12 minutes (Ethereum) | Immediate |
Transaction Cost (Avg.) | $0.001 (fixed) | $1-$50 (variable gas) | $0.0001 |
Throughput (TPS) | 1,000+ TPS | 15-30 TPS (Ethereum) | 10,000+ TPS |
Data Privacy & Control | Full (private chain) | None (public data) | Full |
Settlement Assurance | Cryptographic finality | Probabilistic finality | Trusted third-party |
Regulatory Compliance | Designed for compliance (KYC/AML modules) | Permissionless (compliance challenges) | Established frameworks |
Time to Market | 4-8 weeks (with Chainscore) | Immediate deployment | 3-6 months (custom build) |
Developer Experience | Custom EVM, familiar tooling | Public RPC, congested mempools | Standard APIs, no crypto primitives |
Interoperability | Bridges to major L1/L2s | Native ecosystem access | Closed system, API-based |
Total Cost of Ownership (Year 1) | $50K - $150K (infra + dev) | $100K+ (gas fees + dev) | $200K+ (dev, infra, security) |

Frequently Asked Questions
Get clear answers on timelines, costs, security, and support for your custom payment network development.
From initial design to mainnet launch, a standard deployment takes 6-10 weeks. This includes 2 weeks for architecture and design, 3-4 weeks for core development and smart contract audits, and 2-3 weeks for testing and deployment. Complex integrations (e.g., multi-chain bridges, advanced compliance modules) can extend this timeline, which we scope and agree upon upfront.
