Bitcoin SV network under attack 51% – Bits Media

Yesterday, 3 August, the Bitcoin SV cryptocurrency network was attacked 51%. According to analysts, reorganized 14 blocks.

Initially, the researcher of the analytical company Coinmetrics Lucas Nutzci reported about the attack (Lucas Nuzzi) In the evening 3 August. According to him, yesterday about 11.45 In the morning, a "serious drifting power" appeared on the Web..

Later, Coinmetrics confirmed this information and stated, that her Farum blockchain security tools recorded reorganization 14 Blocks on the Bitcoin SV network. Coinmetrics noted, that the attack is over, But the influence on the mining bullets is still preserved. As reported by NUCSI, as of the evening 3 August Pulas mined coins at "completely different" heights of blocks.

Attack 51% allows the attacker to obtain partial control over the blockchain. It can be used to attack double expenses, Moreover, the likelihood of the success of the attacker becomes maximum. Another possibility of attack 51% - violation of the blockchain work through a complete or partial stop of confirmation of transactions.

The essence of the attack is to receive more 50% Hashrate in blockchains, Using Pow, or 50% Coins in blockchains, Using POS. The larger percentage of control he will be able to get, the faster and more successful the attack will be. Having an advantage over other miners or validators, The attacker can create an alternative chain of blocks and rewrite a certain number of the last blocks with the transactions he needed.

In the evening 3 August The Bitcoin Association recommended that operators of the nodes mark the blocks of the chain of attackers as invalid. Blockchain Bitcoin SV, The Bitcoin Cash has appeared as a result, In July, he was subjected to four attacks. It is not yet clear, Who is behind the attack. Coinmetrics is studying the chain of attackers in search of "traces of double expenses on exchanges", - said NUCSI.

According to him, The main mining pools of Bitcoin SV are still trying to establish work and get blocks in one chain. According to Bitinfocharts, From Monday to Tuesday, the Bitcoin SV hashReite has fallen almost to 50%. However, Nutzzi believes, that this is a consequence of confusion after the reorganization of blocks.

Last spring, analysts reported, that Bitcoin Cash and Bitcoin SV are vulnerable to attack 51% After crashing a reward to the miners.
