Qtum Hard Fork Announcement, November 27th
<h2><span>A call to action for the community</span></h2>
<p><span>This
is a significant step forward for the platform's functionality and efficiency,
not just a routine enhancement. </span></p>
<p><span> </span><br></p>
<p><span>To
prepare for the hard fork, the </span><span><a href="https://qtum.org/"><span>Qtum</span></a></span><span>
team has thoroughly planned and executed a testnet hard fork on October 8,
2023, which served as an essential trial run. </span></p>
<p><span> </span><br></p>
<p><span>This
successful testnet deployment provides a framework for upcoming changes on the
mainnet. </span></p>
<h2><span>Update Required: Qtum Build v24.1</span></h2>
<p><span> </span><br></p>
<p><span>It's
important that all network participants promptly upgrade their Qtum build to
v24.1 before the network reaches block height 3385122 to ensure smooth
operations after the hard fork.</span></p>
<h2><span>Instructions and Resources for Updating</span></h2>
<p><span> </span><br></p>
<p><span>Qtum
has provided detailed instructions and resources on its </span><span><a href="https://github.com/qtumproject/qtum/releases/tag/v24.1"><span>GitHub page</span></a></span><span> to help community members
