Blockchain can be used to develop secure peer-to-peer platforms for exchanging assets without intermediaries and in a trustworthy, sustainable, accountable, and transparent way to fulfill UN SDGs and the objectives of the EU Green Deal. Although research into blockchain has significantly increased in the last few years, there are not many academic or commercial solutions with sustainability and open innovation in mind. Moreover, most of them present solutions at very early stages

Blockchain has the potential to radically change many societal sectors and to foster open innovation in all types of organizations, including supply chains, or the enforcement of governance in a completely innovative way. This overview has inherent methodological limitations due to its length and high level, so only a sample selection of some of the recent solutions is presented to give an idea of the potential of blockchain. The solutions described are not meant to be representative or generalizable. Such cases are the basics for further research, having in mind how blockchain can solve many of the current cybersecurity issues. Furthermore, open challenges were mentioned as a guidance for researchers and companies for future
