Solar Bankers launches first energy sustainable blockchain node

The renewable energy and blockchain company Solar Bankers has taken the next step in decentralizing and increasing the accessibility of blockchain technology with the launch of its Solar Bankers Node – the first energy-sustainable blockchain node that rewards users with Solar Bankers coins.

Solar Bankers has specialized in helping developing countries expand rural electrification with its turnkey solutions for decentralized P2P energy trading, which integrate a micro-grid infrastructure and its patented PV devices with the highly scalable Sky Fiber blockchain platform to provide a complete package of easy-to-use technologies with everything communities need to run a local energy marketplace. This innovative market solution is now available for pre-order at


In order to expand its blockchain ecosystem and increase the scalability of its P2P model, the company has now launched its Solar Bankers Node. The Node is a highly energy efficient Fiber node, running on its own small-scale solar panel. Being completely energy self-sufficient, the Solar Bankers Node represents a major step towards energy-sustainable blockchain development.


Concerns over the energy-sustainability of blockchain technology are mounting. The two largest blockchain platforms, Bitcoin and Ethereum, have long been the focus of controversy due to their high energy consumption. Ethereum, which is the platform of choice for most blockchain companies, is not far behind. With a cumulative consumption of 18.5 TWh last year, the Ethereum network consumed more electricity than the entire country of Iceland. These vast amounts of consumed electricity call for reflection on the further scalability of these two platforms.


With this problem in mind, Solar Bankers embraced the most sustainable blockchain solution on the market today. The Sky Fiber blockchain, developed by early Bitcoin and Ethereum developers, uses less than 1 kWh per transaction and can be run on a device with low computing power. This enabled Solar Bankers to design a blockchain node that does not require any further power supply other than the sun. The Solar Bankers Node mounts a Raspberry Pi and a power bank on a 20-30 W module.


The Fiber technology lends itself for use in energy grid infrastructure due its elimination of the mining requirement, enabling a digital currency system in which coins are transacted in a straightforward, energy-efficient manner. Its web-of-trust consensus algorithm facilitates near infinite scalability, providing each micro-grid with its own blockchain to manage transactions and thus avoiding the frequent overloads experienced by the Ethereum network.


The Solar Bankers Node aims to tie remote developing areas into the globalizing economy not only by facilitating localized energy marketplaces but also by giving households their own energy-autonomous blockchain node to integrate them into an expanding database infrastructure.
