<h4><strong>While the bug caused certain nodes to fall out of sync, block production on the network continued uninterrupted.</strong></h4>
<p>The <a href="https://x.com/0xPolygonFdn" target="_blank" rel="noopener noreferrer nofollow">Polygon Foundation</a>, which oversees the protocol’s development, confirmed on Wednesday that consensus and finality functions have returned to normal.</p>
<h3 id="strong-what-happened-and-how-it-was-fixed-strong"><strong>What Happened and How It Was Fixed</strong></h3>
<p>The issue stemmed from a faulty proposal by one validator, which caused some Bor nodes—responsible for transaction ordering and block production—to diverge onto separate forks. RPC nodes, which help applications communicate with the blockchain, relayed inconsistent data during this time.</p>
<p>Polygon co-founder Sandeep Nailwal explained that the team deployed fixes on Heimdall v0.3.1 and Bor 2.2.11 beta2, removing the problematic milestone from the database. According to Nailwal, “With these fixes now live, nodes are not stuck, checkpoints and milestones are finalizing normally.”</p>

 <p>UPDATE:</p>
 <p>The hard fork has been successfully completed, and milestones are now processing normally along with state sync. Checkpoints are going through and consensus finalization has been fully restored on Polygon PoS.</p>
 <p>We will continue to monitor the network closely to ensure… <a href="https://t.co/UwiAYdcKXu" rel="noopener noreferrer nofollow">https://t.co/UwiAYdcKXu</a></p>

<p>To address the issue, Polygon executed a <a href="https://academy.bit2me.com/en/que-es-hard-fork/" target="_blank" rel="noopener noreferrer nofollow">hard fork</a>. This update corrected node communication, ensuring that all nodes are now aligned with the main chain. While users may have noticed delays in transaction confirmations or discrepancies in node responses, the underlying blockchain remained operational, and new blocks continued to be added without interruption.</p>
<blockquote class="twitter-tweet">
 <p>UPDATE: Milestone fixes rolled out</p>
 <p>We identified the cause of the finality issue and have rolled out v2.2.11-beta2 for Bor and v0.3.1 for Heimdall, the latter a hardfork to be implemented at 3PM UTC.</p>
 <p>We will continue to monitor the network to ensure all issues all resolved.… <a href="https://t.co/NSiS19cd5C" rel="noopener noreferrer nofollow">https://t.co/NSiS19cd5C</a></p>

<p><a href="https://www.alchemy.com/overviews/rpc-node" target="_blank" rel="noopener noreferrer nofollow">RPC nodes</a> are a critical part of blockchain infrastructure because they act as bridges between applications and the blockchain. When nodes fall out of sync, applications may display outdated data or experience temporary transaction delays. However, because Polygon’s block production continued, no on-chain transactions were lost. This is what the Founder and CEO of Polygon said about this:</p>
<blockquote class="twitter-tweet">
 <p>Earlier today, Polygon PoS experienced a disruption where checkpoint finality on Ethereum was still active, but local fast finality on the chain (i.e. milestones) were delayed.</p>

<p>This incident highlights a growing trend in blockchain networks. As smart contracts, file storage, and cross-chain interoperability increase in complexity, software bugs have become more common. In July, Polygon <a href="https://status.quicknode.com/incidents/cjqf5klxfbdh" target="_blank" rel="noopener noreferrer nofollow">faced</a> a similar event when the Heimdall mainnet halted for an hour. These incidents emphasize the importance of robust node monitoring, rapid bug fixes, and coordinated updates to maintain trust in blockchain systems.</p>
