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 v0.18.1 Released: v0.18.1 – Hard Fork Mandatory Update before block 466600 (446320 in testnet) – New features and bug fixes
