data-path-to-node=\"7\">Onchain Data Shows Block Production Halt for Sui Mainnet<\/h2>\n<p><span>The Sui <span>blockchain<\/span> experienced a severe network stall,<\/span><span> halting all block production for exactly five hours and 55 minutes.<\/span><span> According to onchain data from<\/span> Suiscan<span>,<\/span><span> the mainnet <a href=\"https:\/\/x.com\/DegenerateNews\/status\/2060023887467798535\/photo\/1\" target=\"_blank\" rel=\"noopener noreferrer\">stopped processing new checkpoints<\/a>,<\/span><span> effectively freezing all <span>decentralized finance<\/span> ( <span>DeFi<\/span>) activity.<\/span> <span>The Sui core team confirmed the issue on X,<\/span><span> stating that a crash bug in the <span>gas<\/span> charging logic introduced during the 1.<\/span><span>72 release <\/span>caused the disruption<span>.<\/span><\/p>\n<p data-path-to-node=\"9\"><span>The network first alerted users that it was experiencing a stall,<\/span><span> warning that transactions would be delayed while developers worked on a fix.<\/span><span> During the outage,<\/span><span> the network\u2019s native token SUI dropped approximately 6.<\/span><span>6%,<\/span><span> reaching a low of <\/span>$0.90 per unit<span> before partially recovering once services resumed.<\/span><\/p>\n<figure

class=\"wp-caption-text\">Image source: X<\/figcaption><\/figure>\n<p data-path-to-node=\"9\"><span>The incident marked the second major downtime event for Sui in 2026,<\/span><span> following a similar <\/span><a class=\"ng-star-inserted\" href=\"https:\/\/news.bitcoin.com\/from-blocks-to-standstill-sui-mainnet-outage-freezes-onchain-activity\/\">January network stall<\/a><span> that kept validators offline for over six hours.<\/span><\/p>\n<h2 data-path-to-node=\"9\">The Technical Reasoning Behind the Breakdown<\/h2>\n<p data-path-to-node=\"10\"><span>The <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-gas\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">gas<\/a> charging logic is a critical component governing transaction fee calculations,<\/span><span> and a failure at this layer resulted in a complete network freeze rather than degraded performance.<\/span><span> At a high level,<\/span><span> the incident was caused by an edge-case bug in the consensus commit logic related to handling conflicting transactions, causing<\/span><span> different validators to reach different conclusions when computing consensus commits.<\/span><\/p>\n<p data-path-to-node=\"10\"><span>The Sui core stack utilizes multiple layers of transaction processing,<\/span><span> where consensus produces an ordered stream of commits and deterministic execution turns those commits into checkpoints.<\/span><span> Because validators observed that more than one-third of the <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-staking\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">stake<\/a> was signing a different digest,<\/span><span> certification became impossible.<\/span><\/p>\n<p data-path-to-node=\"10\"><span>Consequently,<\/span> v<span>alidators on the Sui mainnet were forced to manually identify the divergence,<\/span><span> implement a fix to purge incorrect consensus data,<\/span><span> and enable corrected logic.<\/span><span> Even after regular operations resumed,<\/span><span> some <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-a-bitcoin-node\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">nodes<\/a> were still reported to be operating with degraded performance.<\/span><\/p>\n<p data-path-to-node=\"11\"><span>While the interruption was unintended,<\/span><span> the network\u2019s default safety-focused architecture behaved as designed by preventing a user-visible fork.<\/span> <span>At the time of the outage,<\/span><span> Sui ranked among the top <a href=\"http:\/\/www.bitcoin.com\/get-started\/what-is-a-blockchain\/\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">blockchain<\/a> platforms by total value locked (TVL),<\/span><span> securing approximately $536 million across 137
