Strategic Infrastructure Decision
Build a Dedicated Fashion Layer vs. Using a Shared L2
A technical and economic comparison for fashion brands and marketplaces choosing between a custom StarkNet Cairo ZK-Rollup and a generic shared L2 solution.
| Key Factor | Build Your Own Layer | Use a Shared L2 (e.g., StarkNet Mainnet) | Chainscore Dedicated Fashion Layer |
|---|---|---|---|
Time to Market | 9-18 months | 2-4 months | 6-10 weeks |
Upfront Development Cost | $300K - $800K+ | $5K - $50K (Gas/Deployment) | $75K - $200K |
Custom Tokenomics & Royalty Logic | Full Control | Limited by L2 Standards | Tailored to Your Brand |
Sequencer & Prover Control | You manage infrastructure | Reliant on L2 provider | Managed by Chainscore with your governance |
Data Privacy & Brand Isolation | Maximum (Your chain) | Shared with all L2 apps | Dedicated execution environment |
Native Fashion Asset Standards | You must develop & audit | Use existing (ERC-721/1155) | Pre-audited, fashion-optimized templates |
Cross-Chain Interoperability | Your team integrates | Native via L2 bridges | Pre-built bridges to Ethereum, Polygon, Base |
Ongoing Maintenance & Upgrades | Full in-house responsibility | Managed by L2 provider | Full-service SLA with 99.9% uptime |
Typical TPS for Fashion Drops | Configurable (10,000+ possible) | Shared capacity (varies) | Guaranteed throughput for your mints |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $50K - $150K | $150K - $300K |
