Solana (SOL), the fifth largest cryptocurrency by market capitalization, tops the on-chain development charts despite a recent denial-of-service (DDoS) attack.

According to Santiment data, Solana has surpassed Polkadot and Cardano’s daily GitHub update rates and has become the top blockchain in the last month. The daily GitHub updates for Solana hit 90 between November 12 and December 13, followed by Polkadot at 76 and Cardano at 65.

The surge in on-chain development activity for Solana continues after a DDoS attack slowed the network significantly last week. Solana was approached to troubleshoot issues without shutting down the network, but it raises serious concerns about the vulnerability of the network.

Many experts blame the DDoS attack on fundamental design flaws and the Solana Proof-of-Histoc (PoH) consensus mechanism. Previously, a report by Grayscale Investment also recalled Solana’s use of the PoH algorithm:

“Solana’s consensus mechanism uses a new blockchain technology that is not widely used and may not work as well as intended. There could be flaws in the cryptography underlying the network, including vulnerabilities that affect the functionality of Solana or make the network vulnerable. ”

Solana faced the same problem in September when a surge in transactions resulted in a network outage that lasted nearly 17 hours. The engineers at the time couldn’t solve the problem and the validators eventually had to restart the network.

Blockchain Solana has become one of the fastest growing smart contracts in 2021 and is a growing choice for upcoming DeFi and NFT projects. The project’s growing popularity is often compared to Ethereum and is referred to by some as the “Ethereum Killer”. However, growing concerns about the fundamentals of the network could make this goal increasingly utopian.

SOL hit a new all-time high of over $ 260 before the DDoS attack, but fell to a weekly low of $ 164.15. It is currently trading at $ 156, according to CoinMarketcap, down 9% in the last 24 hours.
