Tag: What is a good Hashrate for Bitcoin?

To attack Bitcoin you need at least 51% of all the hashrate in the world, now that the miners produce 100 quintillion hashes per second that’s becoming a very expensive and unlikely scenario. In short, the more hashing power used to mine Bitcoins, the harder it is for a single person to get 51% of it.

The Bitcoin hash rate is expressed as hashes per second (h/s) . Bitcoin’s network is large and powerful, and as a result, can calculate quintillions of hashes every second. For reference, a quintillion is a million million millions, or 1,000,000,000,000,000,000.

Each Bitcoin block takes 10 minutes to mine. This means that in theory, it will take just 10 minutes to mine 1 BTC (as part of the 6.25 BTC reward).
