Sui Mainnet Faces Stagnation; Walrus Protocol Read Functions Active

The Sui Network is currently experiencing a significant technical disruption, leading to a temporary cessation of on-chain transactions across its mainnet. As of May 28, 2026, the core development team has confirmed that the network is undergoing stagnation, which has directly impacted ecosystem projects and decentralized applications built on the infrastructure. While write operations are currently stalled, some services remain partially functional through alternative access points.

Impact on Walrus Protocol Operations

The Walrus Protocol, a prominent data storage and availability layer within the Sui ecosystem, has reported that its operations are partially affected by the underlying network failure. Specifically, the protocol is currently unable to process new write operations on the Walrus Mainnet. This limitation is a direct result of the Sui blockchain's inability to finalize new transactions during the period of stagnation.

However, the protocol’s architecture allows for some resilience during such outages. The team stated:

Direct reading function through aggregators is normal due to Sui mainnet network stagnation preventing write operations.

This means that while new data cannot be uploaded to the storage layer, existing data remains accessible to users and developers through decentralized aggregators.

Current Status and Technical Response

The Sui core team is actively working on identifying the root cause of the network stagnation and implementing the necessary repairs to restore full functionality. During this period, the following conditions apply to the network:

• The processing of on-chain transactions has been effectively paused to prevent state inconsistencies.
• Validators and node operators are in communication with the core team to coordinate a network restart or patch deployment.
• Ecosystem protocols like Walrus are maintaining "read-only" states to preserve user access to historical data.

Conclusion

This incident highlights the challenges of mainnet stability within high-performance blockchain environments. While the Sui core team focuses on technical restoration, the ability of protocols like Walrus to maintain read functionality serves as a critical measure for data availability. Users and investors are advised to monitor official channels for a "resume" signal on transaction processing and to expect a backlog of operations once the network returns to its functional state.
