On December 11th, Cyber Capital founder and CIO Justin Bons tweeted that Solana was attacked by DDoS again yesterday. Solana sacrificed decentralization and security for speed. They chose history to prove that the consensus algorithm POH has basic design flaws, because POH will lead to the creation of deterministic blocks.
Previously, most public chains did not choose the POH consensus for good reasons. Only the creation of non-deterministic blocks can increase security and resist censorship. Because no one can predict who will create the next block. In Solana, it is possible to predict and therefore attack the next inline block producer. For example, a hacker can attack the next 100 validators. Rather than attack the entire network, this attack is effective regardless of scale. This severely reduces the SOL security and the ability to resist DDoS attacks, and this attack can also be combined with a 51% attack. Allows an attacker to temporarily gain control of the network by attacking other Stake Holders.
In addition, if combined with Turbine will lead to more dire consequences. Because Turbine divides the transaction memory pool into groups of validators. This means that using PoH, transactions can be reviewed by attacking a specific validator in the next inline group.
