<p>The Ethereum Foundation has <a href="https://x.com/ethereumfndn/status/2096976125511541198?s=20" rel="noopener noreferrer nofollow">graded</a> 62 proposals for the Hegotá upgrade, putting quantum security at the center of its roadmap. On Sept. 7, the Protocol Cluster ranked EIP-7805 and EIP-8141 in the S tier, while setting December 2029 as the target for quantum resistance across Ethereum’s execution, consensus and data layers. The assessment involved roughly 60 contributors.</p>

<h2 class="wp-block-heading" id="strong-hegot-ranking-narrows-the-upgrade-scope-strong"><strong>Hegotá Ranking Narrows the Upgrade Scope</strong></h2>
<p>The Protocol Cluster published its <a href="https://cryptofrontnews.com/ethereum-hegota-upgrade-priorities-put-faster-blocks-first-ethlabs-confirms/" rel="noopener noreferrer nofollow">Hegotá</a> ranking alongside its protocol priorities on Sept. 7. Nine Protocol teams and experts produced 397 grades across 62 proposals. EIP-7805, known as FOCIL, and EIP-8141, known as Frame Transactions, received S-tier status.</p>
<p>S means “must ship,” while A means “expected to ship.” Fifteen proposals received A grades, eight received B grades, and seven received C grades. Meanwhile, the cluster declined 28 proposals, while two remained pending until mainnet evidence becomes available.</p>
<h2 class="wp-block-heading" id="strong-quantum-target-runs-through-2029-strong"><strong>Quantum Target Runs Through 2029</strong></h2>
<p>The Foundation wants <a href="https://cryptofrontnews.com/ethereum-shifts-from-poseidon-as-hash-based-proofs-advance/" rel="noopener noreferrer nofollow">Ethereum’s</a> execution, consensus and data layers to reach quantum resistance by December 2029. It plans that work across several upgrades. The Protocol Cluster said Ethereum should prepare for Q-day as early as 2030.&nbsp;</p>
<p>However, it noted that credible estimates place that threat later, and its arrival remains uncertain. Google, Cloudflare and Microsoft have also set 2029 migration targets. The Foundation will keep its deadline until a January 2027 review with outside experts.</p>
<p>Full post-quantum readiness sits at L*, five forks after Glamsterdam. That schedule requires an average fork cadence of 7.2 months. A minimum viable post-quantum milestone could arrive at J* with a 12-month cadence.</p>
<h2 class="wp-block-heading" id="strong-privacy-and-research-priorities-expand-strong"><strong>Privacy And Research Priorities Expand</strong></h2>
<p>The cluster identified five research areas: fast finality, post-quantum security, privacy, state management and <a href="https://cryptofrontnews.com/early-ethereum-zkrollup-pioneer-loopring-dex-shuts-down-as-zkevms-overtake-its-design/" rel="noopener noreferrer nofollow">zkEVM</a>. It also said Hegotá should begin work on native, trustless and censorship-resistant private transactions.</p>
<p>Vitalik Buterin has discussed replacing vulnerable BLS signatures. The Foundation’s plan also links account abstraction with EIP-8141. Client teams could begin Hegotá implementation in late Q4 2026.&nbsp;</p>
<p>Geth will publish its list, according to the cluster. The Protocol Cluster will hold a Reddit AMA on Sept. 16 at 2 p.m. UTC. Researchers will discuss Hegotá priorities, the tier list and questions.</p>
