Sui and Solana Blockchains Face DDoS Attacks

The attack comes just months after smart contract exploits hit Sui-based projects like Typus Finance and Nemo Protocol. Those incidents drained millions, adding to the concerns about network reliability.

So far, the Sui Foundation has not released an official statement.

Solana: No Slowdowns, Despite Massive Attack

Solana is also under a sustained DDoS attack, but it has shown surprising resilience. Most users did not notice any slowdown. Apps continued working. Even stablecoin activity reached an all-time high of $16.6 billion in circulating supply.

Experts credited Solana’s performance to major backend upgrades over the past two years. The chain previously suffered from outages during high traffic events in 2021 and 2022. But now, it appears to have matured.

The validator count on Solana has dropped from ~2,500 to ~800 since 2023. However, the higher count still offers more DDoS protection than Sui. Also, Solana uses deterministic leader schedules and internal stress testing to prepare for such events.

Some see this attack as part of a larger pattern. On December 12, Solana project Almanak postponed its airdrop due to DDoS issues. This incident may be connected to the broader assault on Solana’s infrastructure.

Community Reactions

Solana co-founder Raj Gokal confirmed the attack but highlighted that performance remained strong. Helius CEO Mert described the event as invisible to most users, calling it proof of network maturity.

Meanwhile, some on crypto X speculated about a “chain war” between ecosystems. Theories included sabotage by competitors or ideologically motivated actors targeting high-throughput networks.

In contrast, Sui’s delays reignited the decentralization debate. Crypto researcher Justin Bons used the incident to warn other chains, including Solana, not to cut validator counts further.
