In April 2016, Tech Bureau, which also operates one of Japan’s largest cryptocurrency exchanges, Zaif, formalized a partnership with NEM by announcing that both Mijin and NEM will share the technology code-named Catapult. Catapult has been in development since early 2016 and is an enhanced version of NEM/Mijin written in C++ and designed to increase throughput, flexibility, stability, optimization of network communication, and scalability, offering better network performance. Following this announcement, Tech Bureau then announced it closed its Series A financing round raising $6.2 million.
Not much is known about Catapult at this point, and the wiki will be updated to reflect new things as they are known.
