Pactus Nexus: Pactus Novel Exchange for Unified Solutions
Pactus Nexus is an open-source, energy-efficient, and scalable blockchain solution designed to meet the objectives of the NGI TrustChain initiative. Built on the Pactus platform and powered by an enhanced Solid State Proof of Stake (SSPoS) consensus mechanism, the project aims to deliver a secure, interoperable, and user-friendly framework for decentralized applications (dApps) across various sectors, including finance, healthcare, and supply chain management.
The project introduces a novel consensus model that reduces consensus steps from three to two, improving computational complexity from O(n²) to O(n). This significantly boosts performance while minimizing energy usage, with validators capable of running on low-power devices such as Raspberry Pi Zero (2W power consumption). This sustainable design ensures environmental friendliness and accessibility, making blockchain participation more inclusive and cost-effective.
Pactus Nexus will provide modular software components, API toolkits, and developer documentation to facilitate integration and adoption. The platform will undergo real-world testing with end-users and stakeholders to ensure functionality, usability, and compliance with GDPR, eIDAS2, and other EU standards. Emphasizing co-creation and user validation, the solution will be tailored to actual market needs through continuous feedback loops.
Expected outcomes include a validated and documented blockchain system ready for distribution, a user-tested prototype reaching TRL 7, and a business plan to support long-term sustainability. The project will also leverage and extend existing IPRs, including the Pactus protocol, PAC token, PAC Viewer, and Sensifai’s AI technologies.
By combining technical innovation with environmental sustainability and practical usability, Pactus Nexus offers a transformative solution for the future of decentralized trust infrastructures, fully aligned with the goals of NGI TrustChain Open Call #5.
- Motivation for the project: Pactus Nexus provides a scalable, energy-efficient, and interoperable blockchain foundation essential for TrustChain, enabling sustainable digital identity, secure data exchange, and inclusive decentralized services across sectors.
- Generic use case description: A lightweight, modular blockchain solution enabling secure, low-energy, and scalable digital identity and data exchange for sectors like finance and healthcare, demonstrating real-world application of the enhanced Solid State Proof of Stake (SSPoS) consensus.
- Essential functionalities: Pactus Nexus offers essential functionalities including an energy-efficient consensus (SSPoS), modular blockchain components, seamless interoperability, decentralized identity support, low-cost validator operation, and open APIs for easy dApp development and integration.
- How these functionalities can be integrated within the software ecosystem: These functionalities can be integrated via open-source modular components, APIs, and SDKs, enabling seamless plug-and-play adoption within the TrustChain ecosystem and ensuring compatibility with existing digital identity, data governance, and cross-chain frameworks.
- Gap being addressed: Pactus Nexus addresses the gap in energy-efficient, scalable, and user-friendly blockchain infrastructure by offering a sustainable alternative to resource-intensive DLTs, with seamless interoperability, low-cost operation, and support for decentralized identity and data exchange.
- Expected benefits achieved with the novel technology building blocks: The novel building blocks enable faster consensus, 90% lower energy use, scalable deployment, and seamless interoperability. They support GDPR-compliant digital identity, reduce operational costs, and promote inclusive, sustainable blockchain adoption across real-world sectors.
- Potential demonstration scenario: A real-world demo in the healthcare sector where patient data is securely shared across institutions using Pactus Nexus, showcasing low-energy validators, fast consensus, GDPR-compliant identity management, and seamless integration with existing TrustChain components.
