Cost of a 51% attack

Online calculator that estimates the cost of a 51% attack on the Bitcoin network.

Uses current network hash rate and mining parameters to approximate how much computing power would be required.

Calculates hardware costs (ASIC miners), infrastructure, and electricity expenses needed to control more than 50% of the mining power.

Demonstrates that executing such an attack would require extremely high investment and energy consumption, making it economically impractical for Bitcoin.

Intended as an educational tool to illustrate Bitcoin’s security model and the economic difficulty of attacking the network.
