In Japan, the government is taking the lead in promoting Society 5.0 and the Digital Rural City concept (regional revitalization). In addition, giant IT companies in the US are advocating web 3.0, with blockchain as the core technology, as the next technology after web 2.0. Blockchain technology is essential for the new digital economy. Distributed ledgers and crypto assets based on blockchain technology have the potential to revolutionize the conventional economic system.

Due to anomalous events in crypto asset transactions, such as money laundering and fraud, there is still a negative view of the new economy based on blockchain technology. Some people may have a negative impression of blockchain, thinking of speculation on crypto assets with inflated prices, money laundering and fraud. However, it would be unwise to miss out on the big benefits just because of the drawbacks. By making use of network science, topology, machine learning, quantum logic, etc., anomalies such as money laundering and fraud, as well as the prediction of price spikes, are possible to a certain extent.

A new system can be created by using the power of mathematics to suppress the shortcomings of crypto asset transactions and by fully utilizing the benefits of distributed ledgers based on blockchain technology. The central concepts of this system are Web3 and the decentralized autonomous organization DAO, which have the potential to become the ‘new economy: the cyber-physical economy.’ We invite you to participate in research on the realization of a ‘cyber-physical economy’ based on blockchain technology.
