Sui confirmed that its mainnet experienced a network stall on <\/span>May 28<\/b> after validators experienced a major outage that temporarily disrupted transaction processing and settlement.<\/span><\/p>\n

In a post on X, the Sui team said the network was “currently experiencing a network stall”. It warned users that transactions could be paused while engineers worked on a solution.<\/span><\/p>\n

The incident appeared to affect mainnet settlement infrastructure rather than isolated frontend or RPC services.<\/span><\/p>\n

Sui’s public status page later showed a “major outage” affecting mainnet validators and listed “mainnet settlement” as an active incident while the team implemented a fix.<\/span><\/p>\n

Explorer activity appeared frozen during outage<\/b><\/h2>\n

Blockchain explorer activity suggested transaction processing stalled for <\/span>more than an hou<\/b>r during the incident.<\/span><\/p>\n

Multiple system-level transactions visible on the explorer displayed nearly identical timestamps, including ConsensusCommitPrologueV4, settlement_prologue, and several programmable transactions.<\/span><\/p>\n

\"Sui<\/a>

The repeated timestamps suggested the network was no longer progressing normally during the outage window.<\/span><\/p>\n

At the time of writing, Sui said the issue had been identified, and a fix was being deployed.<\/span><\/p>\n

The team had not yet publicly disclosed the incident’s root cause.<\/span><\/p>\n

Validator outage appeared isolated to mainnet settlement layer<\/b><\/h2>\n

Sui’s status page suggested the disruption did not affect the broader network infrastructure uniformly.\u00a0<\/span><\/p>\n

While “Sui Mainnet \u2013 Validators” showed a major outage, the project’s public RPC nodes, testnet validators, devnet validators, and related RPC infrastructure all remained operational during the incident.<\/span><\/p>\n

The split suggested the issue primarily affected mainnet validator settlement activity rather than public network access or development infrastructure.<\/span><\/p>\n

The status page also showed Sui mainnet validators maintained roughly <\/span>99.99%<\/b> uptime over the past 90 days before the outage. Outside of the unresolved May 28 incident, the recent operational history appeared largely stable.<\/span><\/p>\n

Reliability remains central challenge for scaling-focused blockchains<\/b><\/h2>\n

The incident renewed attention on the operational complexity of modern high-throughput blockchain networks.<\/span><\/p>\n

Many newer Layer 1 chains optimize heavily for speed and scalability through increasingly sophisticated validator and execution architectures.<\/span><\/p>\n

However, those systems can also introduce additional coordination risks when validator infrastructure or settlement mechanisms encounter failures.<\/span><\/p>\n

\n

Final Summary<\/b><\/h2>\n
    \n
  • Sui confirmed a validator outage disrupted mainnet settlement and temporarily stalled transactions across the network.<\/span><\/li>\n
  • Status page data suggested the disruption remained isolated to mainnet validator infrastructure while RPC nodes and testnet systems stayed operational.<\/span><\/li>\n<\/ul>\n
