NOVA-CIDADE-L3-Test: Blockchain Development and Testing Network

Short Summary

 

The NOVA-CIDADE-L3-Test testbed is a Layer 3 blockchain network built on Arbitrum rollup technology, hosted on dedicated on-premise servers at NOVA IMS. It provides a sovereign, EVM-compatible development and deployment environment for smart contract research and decentralized application prototyping, operating both a test network for experimentation and a main network for operational deployments. The testbed is purpose-built to support smart city and traceability applications, with active projects spanning food provenance tracking in Portugal and peer-to-peer energy sharing initiatives. By running on institutional infrastructure, it ensures data sovereignty and low-latency access for research partners. Its Arbitrum rollup architecture provides Ethereum compatibility while delivering significantly reduced transaction costs and higher throughput, making it suitable for high-frequency traceability and IoT-integrated urban applications.

Application Cases

 

Application case:

Short description:

Food Traceability

Deployment of smart contracts on the NOVA-CIDADE-L3 mainnet to record and verify provenance data across the Portuguese food supply chain. On-chain records provide immutable logs of origin, handling, and transit events, enabling end-to-end traceability from producer to consumer.

Peer-to-Peer Energy Sharing

Smart contract infrastructure supporting decentralized energy trading between prosumers in local energy communities. The network enables automated settlement of energy transactions without intermediaries, supporting Portugal's transition to distributed renewable energy systems.

Smart City Data Governance

Deployment of decentralized protocols for managing urban data streams, including transparent logging of sensor data and public service interactions. Supports auditability and citizen trust in municipal data systems.

Smart Contract Education and Prototyping

The testnet provides a zero-cost, low-risk environment for MSc and PhD students to develop, deploy, and test Solidity smart contracts as part of coursework and dissertation projects, without requiring real assets or external infrastructure.

Note 2: Intellectual property, confidentiality, and exploitation conditions are governed by the applicable NOVA regulations, the CITADELS consortium framework, and any project- or service-specific agreements. Background IP remains with the original rightsholders. Foreground generated through collaborative or service activities will be managed according to the applicable contractual framework, including provisions on ownership, access rights, confidentiality, dissemination, and exploitation. Additional NDAs, data-processing agreements, or specific IP clauses may apply depending on the nature of the data, software, models, or other assets involved.

Note 3: Access is granted on a project-based or institutionally approved basis, subject to feasibility assessment, resource availability, compliance with data protection and security requirements, and acceptance of the applicable terms and conditions. Special arrangements may apply for CITADELS secondments and other approved visiting researcher schemes. Where sensitive, proprietary, or regulated assets are involved, additional safeguards may be required before access is enabled.

Note 4: The NOVA-CIDADE-L3-Test network is built on Arbitrum Orbit, which is released under the Business Source License (BSL 1.1). Under this license, the software may be freely used for non-production, research, and educational purposes. Deployment in a production or commercial environment may require a separate license from Offchain Labs. Users intending to build commercially exploitable applications on this network should seek independent legal advice and, where required, obtain the appropriate license before proceeding. NOVA IMS makes no representations regarding the suitability of this infrastructure for any specific commercial purpose.

Ethical and Societal Aspects

 

Ethical and societal
aspect:

Short description:

Food Safety and Consumer Protection

By providing immutable traceability records across the food supply chain, the testbed contributes directly to public health and consumer rights. Citizens can verify the provenance and handling of food products, reducing the risk of fraud and supporting regulatory compliance with EU food safety legislation.

Energy Transition and Sustainability

The peer-to-peer energy sharing application supports the decentralization of energy systems, enabling local communities to trade renewable energy without reliance on centralized intermediaries. This contributes to the European Green Deal objectives and supports energy poverty reduction by enabling fairer access to clean energy.

Transparency and Accountability in Public Services

Smart city deployments on the network promote transparent, auditable interactions between citizens and public institutions. Immutable on-chain records reduce opportunities for corruption and increase public trust in municipal data systems.

Decentralisation and Reduced Platform Dependency

By providing sovereign, institutionally-hosted blockchain infrastructure, the testbed reduces dependence on commercial cloud blockchain services, supporting digital sovereignty objectives aligned with the EU's digital strategy.

BSL Licensing and Commercial Fairness

Users are required to comply with the Arbitrum Orbit BSL 1.1 license terms. This ensures that commercial actors engaging with the testbed do so on fair and legally sound terms, protecting both the open-source ecosystem and the institution.
