**blockchain**network. It is used to measure how hard it is to find a hash that will meet the current target. The network will adjust the difficulty so that a hash is found every 10 minutes. The difficulty of the network can be measured in hashes per second. If the hash is not found, it will be decreased by

Answer (1 of 5): The “chain” part of

**blockchain****is****hashing**– that**is**, each new block contains the hash of the previous block to ensure there has been no “missing” block between the two, or another block can’t be inserted at a future point.**Hashing**

**is**generating a value or values from a string of text using a mathematical function.

**Hashing**

**is**one way to enable security during the process of message transmission when the message is intended for a particular recipient only. A formula generates the hash, which helps to protect the security of the transmission against tampering.
