Solana Endures One of the Largest DDoS Attacks in History

Solana network faces a massive DDoS attack lasting over a week, with no impact on transaction processing.

At the time of writing, the Solana network is experiencing a massive DDoS attack, ongoing for over a week, according to SolanaFloor. 

🚨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.

Experts report that the intensity reached 6 Tbps. The incident ranks as the fourth largest in history, alongside attacks on Google Cloud, Cloudflare, and AWS infrastructure.

Despite the volume of incoming traffic, the blockchain continues to process transactions normally. 

The Pipe Network team emphasized that the average transaction confirmation time on the Solana network remains around ~450 ms, with the p90 metric being less than 700 ms. 

The project’s founder, Anatoly Yakovenko, described the situation and the blockchain’s response as a “bullish” factor. 

The 6tbps ddos is bullish. Someone is spending as much as the chain makes in revenue to send it bits.

Amid the attack, the price of SOL has decreased by 4% over the past day. At the time of writing, the asset is trading around $127. 

On December 14, the L1 network Sui also experienced a DDoS attack, which resulted in block production delays. 

Update: @SuiNetwork experienced degraded performance due to a DDoS targeting validators

However, all is fixed now and performance has normalized ✅ pic.twitter.com/vY8yuibS1o

The Most Popular Blockchain

The Solana ecosystem has maintained its status as the most popular network among global investors for the second consecutive year in 2025. However, its share of overall interest has significantly decreased, analysts at CoinGecko noted. 

The @Solana ecosystem has recorded its 2nd consecutive year as the most popular blockchain ecosystem, capturing 26.79% of global interest in chain-specific crypto narratives in 2025.

The figure stood at 26.79%—down 12% from the previous year. 

“This reflects the challenges faced by a first-layer blockchain in expanding beyond its close association with meme coin speculation, as well as the sideways movement of SOL’s price, despite broader institutional adoption marked by the launch of ETF in the U.S.,” experts commented. 

In second place is the L2 network Base from the cryptocurrency exchange Coinbase. Its figure fell by 2.9% compared to 2024—from 16.81% to 13.94%. The top three also included the Ethereum blockchain—13.43%. 

Sui and BNB Chain emerged as leaders in interest growth, taking fourth and fifth places, respectively. 

Over the year, Sui’s figure jumped by 6.9% to 11.77%, while BNB Chain’s rose by 4.9% to 9.05%. According to analysts, the latter benefited from the launch of Binance Alpha and the pardon of the founder of the largest cryptocurrency exchange, Changpeng Zhao. 

In December, experts at Glassnode observed a “liquidity reset” in Solana.
