#Bitcoins #Mining Difficulty Level #Miners need to find the #nonce as an #input to the #hash input to guess an #output that starts with a required number of zeros (the #difficulty). Hash output = Hash of (previous block header + merkle root hash + nonce) hash for block number 647,729: 000000000000000000064b9fcad14d747b725552005db1a77e6344a7c672a9bf The #Bitcoin #protocol adjusts the difficulty level every 2,016 #blocks or about every 2 weeks, by adding or removing a leading zero of Hash output. The aim is to produce a new block every 10 minutes.
