律动 BlockBeats 消息，12 月 10 日，Solana 再次遭到 DDoS 攻击，Cyber Capital 创始人兼 CIO Justin Bons 在社交媒体发文表示，Solana 为了速度牺牲了去中心化和安全性，他们选择历史证明共识算法 POH 存在基本设计缺陷，因为 POH 会导致确定性区块创建。此前大多数公链没有选择 POH 共识是有充分理由的，只有非确定性区块创建才能增加了安全性并抵制审查，因为没有人可以预测谁会创建下一个区块。而在 Solana 中，可以预测并因此攻击下一个内联区块生产者，比如黑客能攻击接下来的 100 个验证者，而不是攻击整个网络，无论规模大小，这种攻击都有效，从而严重降低了 SOL 安全性和抵御 DDoS 攻击的能力，而且这种攻击还可以与 51% 攻击相结合，允许攻击者通过攻击其他 Stake Holder 来暂时获得对网络的控制权。此外，如果与 Turbine 结合还会导致更可怕的后果，因为 Turbine 将交易内存池划分为验证者小组，这意味着使用 PoH，你可以通过攻击下一个内联分组中的特定验证器来审查交易。

: The founder's consensus algorithm has design flaws. The founder's consensus algorithm has design flaws. The source of blockchain network rhythm news was attacked again on March. The founder and posted on social media that they sacrificed decentralization and security for speed. The history proves that the consensus algorithm has basic design flaws because it will lead to the creation of deterministic blocks. There is a good reason why most public chains did not choose consensus before. Only the creation of non-deterministic blocks can increase security. Security and resist censorship, because no one can predict who will create the next block, but can predict and attack the next inline block producer, such as a hacker, instead of attacking the whole network. This attack is effective regardless of the scale, thus seriously reducing the security and ability to resist attacks, and it can also be combined with attacks to allow attackers to temporarily gain control over the network by attacking others. In addition, if combined with attacks, it will lead to The more terrible consequence is that the transaction memory pool is divided into verifier groups, which means that you can review transactions by attacking specific verifiers in the next inline group. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
