Dromellar (Andromeda Stellar): A Regenerative AI–Blockchain Currency and Hydrological Infrastructure for Sustainable Digital Economies

The rapid expansion of artificial intelligence (AI) and blockchain technologies has generated new forms of digital economic infrastructure but has also raised increasing concerns regarding environmental sustainability, resource consumption, and the ecological footprint of computational systems. Large-scale data centers supporting AI and cloud computing rely heavily on energy-intensive hardware and water-dependent cooling systems, creating new challenges for sustainable technological development. This paper presents the Dromellar (Andromeda Stellar) framework, a conceptual architecture designed to integrate AI-generated digital assets, blockchain verification mechanisms, and regenerative hydrological infrastructure into a unified digital–physical ecosystem. With regards to the proposed nomenclature, this digital currency should not be confused with XLM’s Stellar, which is an existing cryptocurrency that would be completely distinct from Andromeda Stellar. Just as there are multiple distinct types of physical Dollar currencies – such as the United States, the Canadian and the Australian Dollar. Perhaps as humanity is gradually evolving in her archetype, becoming a constellation-bearing archetype (Homo constellatus), future human societies will start making financial expenditure in “Stellars” – as it poetically rhymes with “Dollars”. The chosen name “Dromellar” is derived from a combination of “Andromeda” and “Stellar” and has been proposed to honour the influential multi-currency name of “Dollar”. Potentially in a similar manner, there could be a new digital currency name of “Stellar” deemed as the “Andromedan Stellar”. Within the present framework, ERC-721 blockchain tokens function as both digital artifacts and sustainability-linked assets whose metadata structures may encode environmental performance metrics. Artificial intelligence systems generate symbolic digital tokens that combine algorithmic design with blockchain-based ownership verification. These tokens operate within a broader digital ecosystem that connects digital economic activity with environmental monitoring systems embedded in physical infrastructure. A central technological component of the framework is a chemical-free closed-loop water purification cascade designed to reclaim water used in computational cooling systems. The proposed eight-stage purification process incorporates thermal energy recovery, mechanical filtration, membrane separation, adsorption, electrodialysis, ultraviolet sterilization, and mineral stabilization to restore water quality suitable for reuse. The system is designed to recover up to 95% of cooling water, thereby significantly reducing freshwater withdrawals associated with large-scale computational facilities. Environmental performance data generated by sensor networks can be recorded on blockchain networks, enabling transparent sustainability accounting through tokenized environmental credits referred to as Aqua Relics, which represent verified volumes of reclaimed water. The framework also introduces the concept of the Stellar Bank, a hybrid institutional model combining digital financial infrastructure with distributed hydrological hubs that provide water regeneration services and community water access points. Perhaps, societies could gradually implement such a digital currency into the physical world, to the point of creating physical coins and notes resembling a form of “Stellar”, golden cash, recognised by a renewed banking system – further stimulating clean water-regenerating and recycling rates of transaction internationally and globally. By linking digital asset generation with ecological restoration mechanisms, the Andromeda Stellar framework explores a regenerative model of digital infrastructure in which computational activity contributes to measurable environmental outcomes. The paper outlines the conceptual foundations, system architecture, hydrological processes, governance mechanisms, and potential societal applications of this interdisciplinary approach to sustainable digital economies aligned with global sustainability objectives.
