<p>Cardano, a decentralized blockchain platform, has <a href="https://app.cgov.io/governance/fdd468da5cc4ac8431dcd7e2b3211666c73bc229f85879469f67f1d9d51d344d%3A0" rel="noopener noreferrer nofollow">officially activated </a>Protocol Version 11 through the Van Rossem hard fork. This makes it the first network upgrade fully approved by the community through onchain voting</p>
<p>The upgrade also brings faster, cheaper smart contracts, giving developers more powerful tools to build on the blockchain.</p>

<p>Cardano has officially activated the Van Rossem hard fork, upgrading the network to Protocol Version 11 (PV11).</p>
<p>Unlike previous upgrades, this marks the first Cardano hard fork approved entirely through onchain governance. The proposal was voted on by Delegated Representatives (DReps), Stake Pool Operators (SPOs), and the Constitutional Committee (CC) under Cardano’s new governance system introduced in the Conway era.</p>
<p>Following the successful activation, Intersect, the organization coordinating Cardano’s governance process, confirmed the upgrade had gone live on the mainnet.</p>

<h2 id="h-what-s-new-in-protocol-version-11" class="wp-block-heading">What’s New in Protocol Version 11?</h2>
<p>Protocol Version 11 mainly focuses on making Cardano smarter, faster, and more efficient for developers building decentralized applications (DApps).</p>
<p>The upgrade introduces several improvements, including:</p>
<ul>
 <li>New Plutus smart contract features are introduced through multiple Cardano Improvement Proposals (CIPs).</li>
 <li>Lower smart contract execution costs with improved cost models.</li>
 <li>Faster processing using new case expressions for Boolean, Integer, and Data types.</li>
 <li>Expanded cryptographic functions, including BLS12-381 support.</li>
 <li>Better consistency across Plutus V1, V2, and V3, allowing developers to use the same built-in functions across all versions.</li>
 <li>Stronger ledger rules and improved network security.</li>
</ul>
<p>According to Intersect, testing showed no performance regressions after the upgrade, while security audits confirmed the safety of the new Plutus features and execution cost models.</p>
<p>The transaction format also remains unchanged, making the transition smoother for existing applications.</p>

<p>Beyond improving today’s network, Protocol Version 11 also lays the technical foundation for <a href="https://coinpedia.org/news/cardano-price-prediction-analyst-says-whale-buying-and-etf-hype-could-signal-bottom/" rel="noopener noreferrer nofollow">Cardano’s</a> upcoming Dijkstra era, where more advanced smart contract capabilities are expected.</p>
<p>Intersect’s Hard Fork Working Group recommended the hard fork in June, and later approved by its Technical Steering Committee before receiving enough governance votes to move forward.</p>
<p>Before activation, Cardano’s Constitution required that at least 85% of active stake pools upgrade to compatible node software, helping ensure a smooth network transition.</p>
<p>Following the successful upgrade, ADA saw a modest market reaction, rising to around $0.1649.</p>
