Solana Withstands One of the Largest DDoS Attacks in Internet History With No Network Disruption

Solana has weathered one of the most powerful distributed denial-of-service (DDoS) attacks ever recorded without any visible impact on network performance.

The attack, which has been ongoing for more than a week, peaked at nearly 6 terabits per second (Tbps), ranking as the fourth-largest DDoS attack in internet history, according to data shared by SolanaFloor.

Despite the scale, network metrics show Solana continued to process transactions normally, with sub-second confirmations and stable slot latency throughout the period.

Solana Joins Google, Cloudflare and AWS in Record-Scale DDoS History

Charts accompanying the disclosure place the Solana incident alongside historic attacks targeting major centralized infrastructure providers, including Google Cloud, Cloudflare customers, Microsoft Azure, and AWS.

While those attacks ranged from 2.3 Tbps to as high as 46 Tbps, Solana’s appearance on the list marks a rare case of a public blockchain facing traffic volumes comparable to the largest assaults on traditional internet services.

Validators and core infrastructure absorbed the traffic without degraded performance, reinforcing claims that Solana’s architecture has matured significantly since earlier congestion episodes.

Meanwhile, the Sui network experienced a DDoS attack just a day earlier, which resulted in delayed block production and periods of reduced performance.

A DDoS attack is an attempt to overwhelm a network, website, or system with massive traffic so it can’t operate normally.

Attackers use large numbers of compromised devices (a botnet) to send junk requests at the same time, flooding the target with data.

The goal isn’t to steal information, but to slow the system down, cause outages, or make services unavailable.

DDoS attacks are not rare in crypto. Last year, the Cardano network experienced an attempted DDoS attack beginning at block 10,487,530.

Raul Antonio, chief technology officer of Fluid Tokens, explained that the attack tried to manipulate the blockchain into charging lower fees for high-value transactions.

Likewise, layer-2 blockchain Manta suffered a DDoS attack shortly after successfully listing its Manta token on multiple exchanges last year.

Solana Faces Liquidity Reset as Losses Mount

As reported, Solana is entering a period of stress as on-chain data points to shrinking liquidity and falling profitability.

Glassnode data shows the network’s 30-day realized profit-to-loss ratio has remained below 1 since mid-November, a level typically linked to bearish conditions, meaning traders are realizing losses more often than gains and market sentiment has weakened.

Analysts at Altcoin Vector describe the situation as a “full liquidity reset,” a phase that has historically marked the early stages of new liquidity cycles and, in some cases, market bottoms.

While near-term volatility remains high, analysts say conditions could begin to stabilize within weeks, potentially setting the stage for a recovery by early January if the pattern mirrors past cycles.

Meanwhile, amid growing demand for Solana funds, Web3 infrastructure provider Alchemy has rebuilt its Solana stack from the ground up, aiming to deliver near-zero downtime, faster transaction speeds, and higher scalability.
