YANO MakotoPresident, RIETI


The Japanese government is aiming to realize Society 5.0, "a human-centered society that integrates cyberspace and physical space." To realize such a society, the creation of "a human-friendly interface" connecting the two spaces will be indispensable. To this end, blockchain (a decentralized ledger) is expected to play a major role. Blockchain is a groundbreaking technology which enables the creation of records (ledgers) on the Internet that cannot be falsified or copied and that are not centrally controlled. Blockchain has been making tremendous advances as a basic technology for building new industries on the Internet. In this Special Seminar, we invited Chris DAI, CEO of LONGHASH, Japan to discuss with YANO Makoto, President & CRO, RIETI, how to ensure the sound development of new industries.
