The NEM Blockchain Project, Version 2.0 – Catapult


Another next milestone for the blockchain tech sector is achieved.






NEM, an ongoing open source distributed ledger technology project, is releasing the whitepaper on a private chain that is being developed by Tech Bureau. Codenamed Catapult, it shall be a successor and second iteration of Tech Bureau’s much touted Mijin private blockchain technology. It is a complete re-hash of the entire blockchain in C++. Further, the platform is re-architected to make use of API gateways, providing superior performance in terms of speed, connectivity, security, extensibility, scalability, and flexibility.

“Catapult is redefining the blockchain architecture landscape. It not only improves on the utility of the blockchain technology, but it also brings enterprise class design into the otherwise rigid and cumbersome blockchain solutions that we are used to.” says Lon Wong, CEO of Dragonfly Fintech & core member of the NEM project” says Lon Wong, CEO of Dragonfly Fintech & core member of the NEM project.
The new architecture allows for true permissioning where every user can be permitted or not, to use the blockchain, or just to see her account activities. All existing business rules of an entity can be reused and integrated with the Catapult via its powerful API gateway.

Further, Catapult is an open system and therefore is a universal standard of, and by itself. Any system can be used to communicate with it, provided it adheres to the standard web design standard.

This flexibility allows for the Catapult blockchain to not only assume 3 important roles – public permission-less, private partially permissioned, and absolutely permissioned – but also allows it to be inter-operable and shareable among different clusters of distributed ledgers.

“Catapult shall be complemented by Dragonfly Fintech’s solution to interoperate from one blockchain cluster to another seamlessly. Together, our solutions shall put us in the forefront of blockchain technology.” — Takao Asayama, Tech Bureau, Corp.

As a permissioned blockchain, the Catapult has been internally tested to scale to 3,000 transactions per second. Catapult will be released as an open source solution and shall be incorporated into the NEM public chain at some point in the future.
