$1.88M Wiped Out As Sui Blockchain Suffers Third Outage Before Recovery

What happened
The Sui blockchain recently experienced a series of significant outages, leading to considerable disruption and impacting investor confidence. Over a 48-hour period, the network suffered three distinct downtime events, culminating in substantial liquidations for leveraged traders. Data from CoinGlass indicated that close to AUD$2.8 million (equivalent to USD$1.88 million) was wiped out in SUI liquidations, with long positions bearing the brunt of approximately AUD$2.55 million (USD$1.72 million) of these losses.
The initial issue, surfacing on May 28, was attributed to a crash bug within the gas charging logic introduced in version 1.72 of Sui's software. This incident resulted in a near six-hour mainnet halt, during which no new block checkpoints were recorded. Following a palliative patch and validator upgrades, the network temporarily resumed operations.
However, this reprieve was short-lived. A second outage occurred just hours later, revealing that the initial fix had only partially addressed the underlying problem. The network again succumbed to a variation of the same core issue. The third and most recent disruption, which hit on May 29, was identified as an issue during an epoch transition at approximately 4:30 PM EDT. While validators continued to generate system transactions, user transactions completely ceased flowing.
The Sui core team ultimately pinpointed a latent bug in how a specific failure state was preserved across validator restarts, preventing the network from completing its move to the next epoch. Reportedly, the root cause across all three outages is linked to modifications in the gas charging logic, which were implemented to facilitate zero-fee stablecoin transfers on the network. Validators have since deployed a definitive fix, bringing the network back online. No user funds were reported lost during these events.
Why it matters for Australian investors
For Australian investors holding or considering SUI, these repeated outages underscore the inherent risks associated with newer, high-throughput blockchain networks. While SUI's price initially fell to approximately AUD$1.37 (USD$0.9035) on international exchanges like Binance following the third stall – breaking the crucial AUD$1.52 (USD$1.00) support level that had held for much of 2024 – the broader impact extends beyond mere price fluctuations.
Such events can erode trust and raise questions about a network's long-term stability and reliability. Australian investors typically utilise platforms like CoinSpot, Independent Reserve, Swyftx, and BTC Markets to trade or hold various cryptocurrencies. While these exchanges are regulated by AUSTRAC for anti-money laundering and counter-terrorism financing purposes, the security and performance of the underlying blockchain network remain a critical factor.
Disruptions can lead to missed trading opportunities, difficulties in moving assets, or, in the case of leveraged positions, significant liquidations. The Australian Taxation Office (ATO) views cryptocurrency as property, meaning any gains or losses from SUI trading would be subject to capital gains tax (CGT). Prolonged downtime, while not directly impacting the ATO's tax treatment, adds another layer of uncertainty for investors needing to manage their portfolios and accurately record transaction times for tax purposes.
Furthermore, the Australian Securities and Investments Commission (ASIC) focuses on consumer protection and market integrity. While ASIC's direct oversight of individual blockchain networks is limited, repeated incidents like Sui's outages highlight the volatility and operational risks that Australian investors should be acutely aware of when engaging with decentralised finance (DeFi) protocols and relatively new Layer 1 blockchains.
Impact on the AUD market
The immediate impact on the broader Australian dollar (AUD) cryptocurrency market stemming from Sui's outages is likely limited, given SUI's market capitalisation relative to dominant assets like Bitcoin (BTC) and Ethereum (ETH). However, the incident serves as a cautionary tale for the burgeoning Australian crypto ecosystem.
Australian investors are increasingly looking for transparent and reliable blockchain infrastructure. Downtime on any major blockchain, even a smaller one in global terms, contributes to the overall perception of risk within the digital asset space. This can influence allocation decisions, potentially leading some investors to favour more established, battle-tested networks.
While trading activity for SUI on Australian exchanges isn't as high-volume as on international platforms, Australian users can still be exposed to price volatility via cross-exchange arbitrage or simply holding the asset. Any significant price depreciation on global markets due to network instability will naturally flow through to AUD-denominated prices on local platforms.
Another consideration for the AUD market is the potential for regulatory scrutiny. Repeated, high-profile outages could draw increased attention from Australian financial regulators. While the direct cause may be a technical bug, the broader narrative of instability in a decentralised financial system could inform future policy discussions regarding investor protection within the Australian crypto landscape.
What to watch next
Moving forward, Australian investors should closely monitor several key developments related to Sui. The Sui team has indicated that a detailed incident review is forthcoming. This review will be crucial for understanding the full scope of the issues, the preventative measures being implemented, and the network's commitment to long-term stability.
Investors should also observe the network's performance for any further signs of instability or recurrence of similar issues. While the immediate fix has brought the network back online, the nature of these outages, particularly their recurrence and the link to gas charging logic, suggests a need for robust and thoroughly audited software development practices.
Track SUI's price action on major exchanges and observe whether it can regain the previously significant AUD$1.52 (USD$1.00) support level. Sustained trading above this mark might indicate renewed investor confidence, while continued weakness could signal ongoing concerns.
Finally, the broader implications for Layer 1 blockchain development are worth watching. The challenges faced by Sui underscore the complexities of scaling and securing decentralised networks while introducing new features like zero-fee transactions. Australian investors should continually evaluate the fundamental technology, development teams, and decentralisation efforts of any blockchain project they consider, understanding that even established networks can face unforeseen technical hurdles.

Common questions
How does the ATO tax SUI if it experiences repeat outages?
The Australian Taxation Office (ATO) treats SUI, like other cryptocurrencies, as property for capital gains tax (CGT) purposes. Repeat outages do not change this tax treatment. Any profit made from selling SUI is subject to CGT, and losses can be used to offset future capital gains. It's crucial for Australian investors to keep precise records of all transactions, including acquisition costs, sale proceeds, and dates, regardless of network stability issues, to ensure accurate tax reporting.
Can I still trade SUI on Australian exchanges during an outage?
During a blockchain outage, an Australian exchange like CoinSpot or Swyftx would likely halt trading for the affected asset. This is because the underlying network is not processing transactions, making it impossible to facilitate deposits, withdrawals, or sometimes even internal transfers. While your SUI holdings on an exchange are generally safe (as no user funds were reported lost in these specific outages), you would be unable to execute trades until the network and the exchange resume normal operations.
What Australian regulations cover the risks of blockchain outages for investors?
While no specific Australian regulation directly governs individual blockchain network outages, several regulatory bodies play a role in investor protection. AUSTRAC focuses on anti-money laundering and counter-terrorism financing for Australian crypto service providers. ASIC is responsible for market integrity and consumer protection, potentially looking into how exchanges manage and communicate risks to Australian investors during such events. Investors should be aware that the inherent technical risks of blockchain networks are largely outside direct regulatory control, emphasising due diligence before investing.
