 Smart contracts on Cardano are simple programs often referred to as validator scripts in which users define custom logic. They are automatically executed by each Cardano node validating the transaction when the transaction attempts to move funds from the script's address. The address of each script is derived from the hash-sum of the compiled script. 
 
-Once deployed, smart contracts become immutable, which means they cannot be changed. They are distributable and tamper-proof, fast, and cost-effective, as there is no middleman, which saves both money and time.
