What is the terminologi for an address that starts with
tz and for one that starts with
KT1? The former is controlled by a secret key, and the latter is controlled by a piece of Michelson code that was published on the blockchain.
As said in the glossary,
tz accounts are called "implicit accounts" and
KT1 accounts are called "originated accounts" or "smart contracts" (these two expressions are synonyms since Babylon).
