Scalability Over Stability? Solana Experiences Third Network Outage in Six Months

Since launching its Proof of History, Solana has suffered issues with stability. In the last six months, the Solana network has recorded three outages.

Solana prides itself on being the world’s first web-scale blockchain. The project quickly rose up the crypto rankings as it sported a highly scalable, decentralized blockchain capable of consistently processing over 2,500 transactions per second and of reaching an impressive 50,000 TPS.

Solana has taken an uncommon path when compared to the rest of the industry, having implemented the Proof of History blockchain model (PoH) which creates a historical record for events that occur on the network. While other blockchains require validators, Solana’s validator maintains its own clock by encoding time passage in a simple SHA-256, thereby making transaction confirmations faster.

Solana Suffers Another Outage After a DDoS Attack

Since launching its Proof of History mechanism, Solana has suffered serious issues with stability, and the Solana network has recorded three outages in the last six months


On September 14th, the Solana network was offline for 17 hours. Then, in December, the Solana network experienced a sudden drop in transaction speeds after another DDoS attack

The most recent was recorded in the early hours of Tuesday, January 4th, when the Solana network was reportedly hit with a distributed denial-of-service (DDoS) attack. The DDoS attack sent the Solana Network offline for a couple of hours.

Wu Blockchain announced that by 8:00 UTC, the issue had been fixed, and Solana was back to functioning properly. A Grayscale security report explained that the DDoS attacks on Solana stemmed from possible flaws in the network’s cryptography.


Justin Bons of Cyber Capital claimed that Solana’s proof of history consensus model may not be sufficiently secure against DDoS attacks.

On the Flipside

  • Despite its lack of stability, Solana remains one of the fastest networks around, claiming to be able to process 50,000 transactions per second.

Why You Should Care

Although Proof of History drastically improves the speed and capacity of the Solana network, stability has to be prioritized for sustainable network growth.
