A 51% attack occurs when a cryptocurrency miner or group of miners gains control of more than 50% of the blockchain of a network. The 51% attack scenario is uncommon, especially for more established cryptocurrencies, due to the logistics, hardware, and costs involved. However, a successful block attack may grant the attacker complete network control, allowing them to double-spend coins, prevent other transactions from confirming, and prevent other miners from mining.
