Architecture Decision Matrix
AppChain vs. Shared L1/L2: A Performance & Privacy Comparison
A technical breakdown of how a dedicated AppChain compares to deploying on a shared public network for applications requiring high performance and data privacy.
| Architecture Factor | Shared L1/L2 (e.g., Arbitrum, Base) | Privacy-First AppChain |
|---|---|---|
Transaction Throughput (TPS) | Shared with all dApps on chain | Dedicated capacity, 1000+ TPS |
Transaction Finality | Network-dependent (2-60 sec) | Sub-2 seconds (configurable) |
Transaction Cost | Volatile, subject to network congestion | Predictable, fixed or near-zero |
Data Privacy | All data public on-chain | Private mempool, encrypted state, selective disclosure |
Customizability | Limited to base chain rules | Full control over VM, consensus, gas rules |
Time to Deploy | Days (smart contract deployment) | 4-8 weeks (full chain development & audit) |
Security Responsibility | Relies on base chain security | Your team + our audit; sovereign security |
Development & Maintenance Cost (Year 1) | Low upfront, high variable op-ex | $150K-$500K+ CapEx, predictable op-ex |
Ideal Use Case | Public DeFi, NFTs, general dApps | Institutional DeFi, enterprise B2B, compliant gaming |

PREDICTABLE, TRANSPARENT, AND SECURE
Our 4-Phase Delivery Process
We deliver production-ready, privacy-first AppChains through a structured, milestone-driven approach. Each phase has clear deliverables, technical reviews, and client sign-offs, ensuring alignment, mitigating risk, and guaranteeing a successful launch.
01
Phase 1: Architecture & Design
We define your AppChain's core architecture, including consensus mechanism (e.g., Tendermint, Geth fork), privacy layer integration (ZKPs, TEEs), and tokenomics. This phase establishes the technical blueprint and security model.
Deliverables: Technical Specification Document, Network Architecture Diagram, Initial Threat Model.
2-3 weeks
Typical Duration
3+
Design Reviews
02
Phase 2: Core Development & Privacy Integration
Our engineers build the chain's core logic, custom modules, and integrate chosen privacy primitives (e.g., Aztec, zkSync's ZK Stack). All code follows OpenZeppelin standards and is developed with comprehensive unit/integration tests.
Deliverables: Deployable Chain Codebase, Privacy Module SDK, Initial Testnet Deployment.

03
Phase 3: Security Audit & Hardening
The codebase undergoes rigorous internal review followed by an external audit from a top-tier firm (e.g., Trail of Bits, Quantstamp). Vulnerabilities are remediated, and the chain is stress-tested under mainnet-like conditions.
Deliverables: Final Audit Report, Remediation Log, Performance Benchmark Report.

Phase 4: Deployment & DevOps
We deploy the validated AppChain to your chosen infrastructure (cloud, bare metal) with automated CI/CD, monitoring (Prometheus/Grafana), and alerting. We provide full documentation and handover operational runbooks to your team.
Deliverables: Live Mainnet, DevOps Pipeline, Monitoring Dashboard, Operational Runbooks.

Frequently Asked Questions
Get clear answers on timelines, security, costs, and our development process for building confidential blockchain applications.
From initial design to mainnet launch, a standard deployment takes 4-8 weeks. This includes 1-2 weeks for architecture and privacy model design, 2-4 weeks for core development and integration of privacy modules (like zk-SNARKs or secure enclaves), and 1-2 weeks for testing, security audit review, and deployment. Complex protocols with custom privacy logic can extend to 12+ weeks. We provide a detailed project plan with milestones during the discovery phase.
