A 51% attack on Monero (XMR) has rattled the crypto community, leading Kraken to temporarily halt deposits. What are the implications for blockchain security ? Here's a deep dive into the issues and outlook for 2025.
The renowned crypto exchange Kraken has announced the temporary suspension of Monero (XMR) token deposits on its platform following a 51% attack against the Monero network. This major takeover raises concerns about the network’s integrity and the potential risks it poses.
For context, 51% attacks are among the most feared scenarios in the cryptocurrency universe. This type of attack occurs when a group of miners manages to control more than 50% of a blockchain network’s computing power. In Monero’s case, the Qubic project reportedly seized the majority of the hashrate through a useful proof of work (uPoW) mechanism.
This network takeover by Qubic represents a serious threat to Monero’s integrity. It could enable transaction censorship, double-spending, and even block reorganization, severely compromising the network’s reliability.
Faced with this critical situation, Kraken decided to temporarily suspend deposits of Monero as a precautionary measure. Although XMR’s price initially dropped following this announcement, the cryptocurrency appears to be gradually recovering, showing an increase of nearly 12% over the last 24 hours.
The crypto community remains vigilant regarding the evolution of this 51% attack and its potential repercussions on the Monero network. Market participants will need to collaborate closely to strengthen the security of this decentralized blockchain.
This incident once again highlights the critical importance of security in the cryptocurrency ecosystem. 51% attacks represent a serious threat that challenges the principles of decentralization and blockchain integrity.
