Summary

Monero recently experienced an 18-block reorganization, triggering concerns about the potential for double-spend attacks. Security expert Cosine from SlowMist emphasized the need for the Monero community to address such issues to prevent ongoing threats. While a double-spend attack is not imminent, the possibility remains, even without 51% hash power control. Experts suggest requiring more than 10 confirmations for XMR transactions to mitigate risks from these reorganization events.
