Sui Mainnet Suffers Two Outages in Two Days After Gas Bug
Sui’s mainnet experienced two separate outages over a two-day span after a gas logic bug stalled transaction processing across the network, raising immediate questions about the Layer 1 blockchain’s operational reliability.
What happened during Sui’s two mainnet outages
The Sui network went down twice in rapid succession, with both incidents occurring within a roughly 48-hour window. During each outage, mainnet transaction processing stalled, leaving users unable to execute transfers or interact with decentralized applications built on the chain.
The disruptions were logged on Sui’s official status page, which tracks network incidents and resolution timelines. A fix was subsequently released as mainnet-v1.72.4, targeting the underlying issue.
WHAT TO KNOW
- Outage count: Two mainnet outages within two days
- Impact: Transaction processing stalled, blocking user activity network-wide
How a gas logic bug stalled transactions
The root cause has been attributed to a bug in Sui’s gas logic, the mechanism that meters and prices computational resources for on-chain operations. When gas calculation malfunctions, validators cannot properly process or finalize transactions, effectively halting the network.
Gas systems are critical infrastructure for any blockchain. A flaw at this level does not just slow throughput; it can prevent any transaction from completing, which is consistent with the full stalls observed during both incidents.
Why back-to-back outages raise reliability concerns
A single outage can be treated as an isolated incident. Two outages in two days suggests a deeper stability problem that a single patch did not fully resolve on the first attempt.
For users and developers on Sui, stalled transactions mean frozen assets, failed trades, and interrupted application logic. DeFi protocols on the network, which handle real capital flows, are particularly sensitive to downtime of this nature.
The reliability question becomes especially relevant as blockchain ecosystems compete for developer and user attention. On Solana, for instance, platforms like Pump.fun have generated massive activity volumes, demonstrating the kind of sustained usage that demands consistent uptime from underlying infrastructure.
Network stability is also a factor for institutional participants evaluating Layer 1 platforms. Events like the Artificial Intelligence Summit in Indonesia and GovXcellence Jakarta have highlighted the growing intersection of blockchain technology with government and enterprise adoption, where reliability is a baseline requirement.
The consecutive failures put pressure on Mysten Labs, the primary developer behind Sui, to demonstrate that its validator infrastructure and protocol logic can support mainnet-grade reliability as the ecosystem scales.
