Crypto Exchange Kraken suspended the Monero (XMR) deposits after the network underwent a confirmed attack of 51% on August 12, which raised new concerns concerning the safety of evidence of proof of medium -sized work.
According to network data, the Extraction Pool Qubic briefly controlled more than half of the Monero hashrate, culminating at 2.6 GHG / s. This majority dominance allowed Qubic to reorganize the blockchain blockchain in depth, effectively rewrite the history of transactions and orphan of around 60 blocks.
Kraken intervenes as a precaution
Kraken said in a statement that Monero’s deposits had been interrupted as a safety measure:
“As a security precaution, we have taken a break of monero deposits (XMR) after having detected only one mining pool has gained more than 50% of the total hashness of the network. This concentration of mining power poses a potential risk for the integrity of the network. We are actively monitoring the situation and will resume the deposits once we determine it.
Pressure corner of confidentiality
Monero, launched in 2014, is known for its strong confidentiality features. Unlike Bitcoin and Ethereum, Monero hides the amounts of the sender, the receiver and the transaction, making it a favorite choice for users looking for anonymity. Although these features stimulate adoption among the defenders of privacy, the smaller hashrate of the network compared to high -level blockchains leaves it for a long time vulnerable to majority attacks.
The recent feat underlines these risks, stressing how concentrated mining pools can temporarily undermine the integrity of networks focused on privacy.
