The rise of cryptocurrencies has shone the spotlight on their underlying technology, which is known as the blockchain.

A wide number of startups are now pitching services using the technology, which is often touted as the next major development since the internet.

This trend was visible at a two-day blockchain conference in Tokyo last week that attracted nearly 100 firms, including many from overseas, who showcased a variety of products. Their offerings ranged from job matching platforms and cosplay ecosystems to health care services and even a smartphone handset.
