Solana Weathers One of the Largest DDoS Attacks in Internet History—Network Never Skips a Beat

Solana just shrugged off a digital tsunami.

The blockchain faced down what's being called one of the largest distributed denial-of-service attacks in internet history. The sheer scale of the assault would have crippled lesser networks, flooding them with malicious traffic until they buckled under the pressure.

The Attack That Wasn't

Here's the kicker: there was zero network disruption. No halted transactions, no frozen validators, no panicked tweets from developers. While the attack raged, Solana kept processing transactions as if it were just another Tuesday. The network's architecture—its unique proof-of-history consensus—acted like a digital seawall, letting the flood of junk data wash past without eroding the core ledger.

Resilience by Design

This wasn't luck; it was a stress test passed with flying colors. The event proves the network's underlying infrastructure can handle extreme, coordinated offensives. It validates the engineering choices that prioritize throughput and finality, even under fire. For a chain often criticized for past outages, this silent victory speaks volumes about its maturation.

A New Benchmark for Blockchain Strength

The attack sets a new, brutal benchmark for what constitutes a 'large-scale' DDoS in the crypto world. Solana's ability to absorb it without a hiccup sends a clear message to both adversaries and institutional onlookers: this network is built tough. It turns a potential PR nightmare into a powerful demonstration of anti-fragility.

In a sector where 'security' is often just a marketing bullet point, Solana just showed its receipts. While traditional finance frets over IT patches and compliance forms, a decentralized network just survived a firefight that would have taken legacy systems offline for days—all without a central incident response team. Maybe the 'wild west' of crypto is building better fortresses than the old guard.

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.

BREAKING: @Solana has been under a sustained DDoS attack for the past week, peaking NEAR 6 Tbps, the 4th largest attack ever recorded for any distributed system. Network data shows no impact, with sub second confirmations and stable slot latency.

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.
