On March 18th, when investors are immersed in FIL currency to break through the 100U new high carnival, multiple media reported that the Filecoin main network at night suspected that there was a double flower vulnerability. At one time, the price of Fil was adjusted to 74U. Filecoin officially investigated it immediately, saying that no network problem or API vulnerabilities were found. The root cause of this problem was caused by the incorrect use of the exchange Lotus API, and only one exchange received this. Influence. The Lotus team is working with all exchanges to correct their use of API and determine the use specifications. Mo major media have reposted official reports to clarify the facts. At this point, the problem with the Filecoin main network dual flower has come to an end. Perbid may have questions, what is the "double flower problem"? Why does it cause such a great impact? In short, according to the literal meaning, it is spent twice or many times in a sum. It ’s like I spent 100 yuan for shopping in Alipay. As a result, the Alipay system produces bugs. Deduct, then I use these 100 yuan to eat, this is the problem of double spectacles! If this is OK, there will be no trust in the blockchain. rn rn rn 双花问题是怎么产生的rn 1、控制超过51%的算力：当第一次的交易通过验证并记录在区块中后，在The network is used to verify the new blockchain with a better computing power, and this digital asset is spent for the second time in the new chain. Because the new blockchain is longer, this will lead to the first exchange The blockchain is abandoned, and the digital assets spent for the first time will return to the account, which causes double flowers. Therefore, on the Filecoin network, the official control of the effective computing power of a single node cannot exceed 20%of the entire network. This is also to avoid the phenomenon of controlling the entire network's computing power, and now the effective computing power of the Filecoin network has reached 3.377EB. The cost of attack is too high; 2. Time difference: Due to the consensus mechanism, the block confirming the time for a long time, and the transaction is used with a certain number of digital currencies. Before this transaction is confirmed, it will be conducted twice again before the completion of this transaction. Transaction;
Has "double flower vulnerabilities" in history In 2018 a miner control at least 51%of the computing power of BTG (bit gold), successfully steal 38 on the exchange Ten thousand BTG, currently worth as high as $ 12 million; In 2019 attackers rent more than 51%computing power, conduct double -flower attacks, at least 54,000 ETCs, currently worth about $ 650,000;
