Smart City Infrastructure Comparison
Legacy vs. Blockchain-Integrated Architecture
A direct comparison of traditional centralized systems versus a blockchain-integrated approach for municipal services, highlighting key operational and security differences.
| Architecture Feature | Legacy Centralized System | Blockchain-Integrated System |
|---|---|---|
Data Integrity & Audit Trail | Manual logs, prone to tampering | Immutable, cryptographically verifiable ledger |
Inter-Departmental Data Sharing | Siloed APIs, complex integrations | Permissioned, real-time shared state |
Citizen Identity & Access | Fragmented logins per service | Unified Self-Sovereign Identity (SSI) |
Transaction Finality & Settlement | Batch processing, days to clear | Near-instant, cryptographic settlement |
System Uptime & Resilience | Single points of failure, planned downtime | Decentralized network, 99.9%+ uptime SLA |
Fraud & Corruption Risk | High, relies on manual oversight | Low, enforced by smart contract logic |
Development & Integration Time | 12-24 months for new services | 3-6 months with reusable modules |
Ongoing Maintenance Cost | High (vendor lock-in, legacy support) | Predictable (open-source, modular upgrades) |
Compliance & Reporting | Retroactive, audit-intensive | Real-time, transparent, and programmable |

Our Phased Migration Methodology
Our structured, four-phase approach ensures your city's legacy systems transition to a secure, scalable blockchain with zero service disruption and measurable outcomes at each stage.
01
Phase 1: Discovery & Architecture
We conduct a comprehensive audit of your existing infrastructure and data models to design a future-proof blockchain architecture. Deliverables include a detailed migration blueprint, interoperability mapping, and a phased rollout schedule.
2-4 weeks

Phase 2: Pilot & Smart Contract Development
We build and deploy a pilot on a private testnet, focusing on a non-critical service (e.g., document notarization, permit tracking). Smart contracts are developed in Solidity 0.8+ with OpenZeppelin libraries and undergo formal verification.

Phase 3: Staged Production Migration
We execute the migration in controlled stages, moving one service module at a time with real-time monitoring and rollback protocols. This ensures 99.9% uptime for legacy systems while the new blockchain layer is activated.

Technical & Commercial Questions
Smart City Migration FAQs
Answers to the most common questions from city planners, CTOs, and procurement officers about migrating public infrastructure to blockchain.
A phased deployment typically takes 8-16 weeks from kickoff to production. This includes 2 weeks for discovery & architecture, 4-8 weeks for core development and integration, and 2 weeks for security audit, testing, and go-live. For proof-of-concept pilots, we can deliver a functional MVP in under 4 weeks.
