Quick Breakdown
- Assault peaked at 6 terabits per second, the fourth-largest ever, behind strikes on Google Cloud and AWS.
- Blocks processed in under one second; validators stayed online 100% with no user impact.
- Following Sui’s recent DDoS struggles, where blocks lagged, Solana showed superior stability.
Assault rivals global giants, leaves Solana unscathed
Solana faced a multi-day DDoS flood peaking at 6 Tbps on December 15, according to data from Pipe Network and SolanaFloor. The attack flooded RPC endpoints without causing any block delays, slot skips, or failed transactions across the chain. Validators maintained normal vote rates while processing routine volumes of over 100 million daily transactions.
🚨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.

Network upgrades, such as QUIC transport and stake-weighted Quality of Service, handled the surge. This marks a turnaround from 2022 outages, when smaller DDoS waves halted operations for hours. Recent hardening, including firewall rules and endpoint limits, blocked the traffic before it overwhelmed consensus.
Uptime boosts Solana’s enterprise push
The document highlights that Solana’s flawless handling of a record 6 Tbps DDoS attack bolsters its suitability for enterprise use. This is supported by ecosystem achievements such as Kraken’s tokenized stocks via Backed Finance and the partnership between Taurus and Everstake for custody staking. Furthermore, institutional confidence is evident, as Forward Industries has appointed Ryan Navi as CIO to build Solana treasuries.
The live Base-Solana Bridge significantly advances cross-chain capabilities, a collaboration with Coinbase and Chainlink CCIP. This bridge enables secure and seamless transfer of assets like SOL between the Base and Solana networks, unifying liquidity. This allows developers to integrate native Solana assets into Base applications, simplifying cross-chain movement and driving adoption across DeFi, gaming, and NFTs.
A significant institutional milestone was achieved when Galaxy Digital completed one of the first U.S. commercial paper issuances and settlements on a public blockchain, specifically leveraging the Solana network. This landmark transaction, arranged by J.P. Morgan and purchased by institutional investors including Coinbase and Franklin Templeton, settled in USDC stablecoins. This move from theoretical experimentation to active institutional participation showcases how Solana’s programmable infrastructure can enhance the efficiency and security of capital markets for sophisticated investors.
