Monero Faces 18-block Reorg as Experts Warn of Double-Spend Risks

Monero (XMR), one of the leading privacy-focused cryptocurrencies, recently went through a significant network disruption.

Reports highlighted that the blockchain experienced an 18-block reorganization, a rare but serious event that temporarily rewrites transaction history. Such reorganizations can shake confidence among users and service providers, especially when transaction security is at stake.

Why it matters

Normally, Monero transactions are treated as reliable once they reach ten confirmations. However, following this reorg, analysts recommend waiting for more confirmations to ensure payments remain valid. The sudden shift revealed how vulnerable networks can become when block sequences are altered, increasing the likelihood of double-spending scenarios.

Expert warnings

Blockchain security specialist @evilcos from SlowMist cautioned that ignoring the risks tied to reorganizations leaves the community exposed. He compared the threat to a “Damocles’ sword,” stressing that such dangers constantly loom over proof-of-work blockchains if vigilance is neglected.
