Qtum Core

Qtum core updates normally consist of Qtum Improvement Protocols. These QIPs are generated by both our developers and the community and in some cases requests from enterprise users. Our developers evaluate the impact of each QIP and work on high priority QIPs. All bug fixes and feature enhancements that have been issued to the core project will be listed here.

Qtum Neutron

Qtum Neutron is a new smart contract platform being built on top of Qtum. It is designed with several security improvements and to enable smart contracts to take full advantage of Qtum's features. Smart contracts can be written in Rust for the Qtum Neutron platform.
