Monero Shows 51% Vulnerability — Reputation at Risk

I explain why a 51% attack is dangerous: in Proof-of-Work systems one participant must not control more than 50% of the hashrate, because that concentration breaks the basic security assumptions.

The risks from a 51% attack include double-spending my own transactions, temporarily freezing or undermining the network, and forcing repeated chain reorganizations that create instability.

For Monero, this is a reputational hit — it markets itself as decentralized, yet hashrate concentration shows vulnerability. If the control lasted only a few hours and then dispersed, the immediate damage may be limited, but the episode reveals a real centralization risk.
