Solana’s blockchain network appears unimpacted after a massive DDoS attack peaking at 6 terabits per second (Tbps), described as one of the largest in history.

The attack lasted over a week, targeting Solana’s infrastructure during high-activity periods like the Breakpoint event, yet causing zero downtime or performance degradation.

This story is an excerpt from the Unchained Daily newsletter.

A Denial of Service (DoS) attack occurs when an attacker uses a single device to inundate a target with excessive traffic, overwhelming its systems and disrupting normal operations.

Last week, Solana founder Anatoly Yakovenko described the attack as “bullish,” saying “someone is spending as much as the chain makes in revenue to send it bits.”

The Sui network, which was also targeted by a DDoS attack, experienced degraded performance and transaction delays earlier in the week.
