Simply put, hash rate is a measure of the processing power of the Bitcoin network that helps you in strengthening your security. When Bitcoins are mined, blocks of verified transactions are ‘hashed’ or secured at a particular rate before adding to the blockchain. When the bitcoin network reaches a hash rate of 10 Th/s, it means it could make 10 trillion calculations per second. The hash rate is a measure of how many times the network can attempt to complete ‘hashes’ per second.
