everyone thinks everyone else is doing it,
so everyone claims they are doing it….”
(Chris de Rose 2015/Dan Ariely 2013)

Pre-written logic (computer code) Stored and replicated on a
distributed storage platform (eg a
blockchain)
Executed/run by a network of
computers (usually the same
ones running the blockchain) and
can result in ledger updates
(cryptocurrency payments, etc)
