WEB3 engineer's journey

WEB3 is a group of technologies that will support the next generation of the Internet, including distributed ledger technology (DLT), cryptography theory, smart contracts, DApps development, and token economics. I am studying these at the University of Tokyo's Blockchain Innovation Endowed Chair to delve deeper into the latest trends and technologies in the industry.

DLTs are used in a wide range of sectors, from finance to logistics, and improve transparency and trust by eliminating centralized control. Cryptography secures data, smart contracts streamline business, DApps provide users with freedom and control, and token economics shape new economic models.

In this blog, I will explain the latest technologies and trends I have learned in an easy-to-understand manner and explore the future of web3. Please stay tuned.
