The surge in on-chain development activity for Solana comes in the wake of a recent DDoS attack on Thursday that slowed down the network considerably. The fifth-largest blockchain managed to mitigate the issues without a network shutdown, but it raised serious concerns over network vulnerability.

A DDoS attack refers to a coordinated botnet-targeted activity that overwhelms a network with fake traffic. Many experts blamed the coordinated DDoS attack on fundamental design flaws and Solana’s proof-of-history (PoH) consensus mechanism. Earlier, a Grayscale Investment report also flagged Solana’s PoH use and said:

“The Solana consensus mechanism uses a new blockchain technology that is not widely used, and may not function as intended. There may be flaws in the cryptography underlying the network, including flaws that affect the functionality of the Solana Network or make the network vulnerable to attack.”

In September, the Solana network faced a similar issue when a sudden surge in…
