My favourite pet peeve -> essence of public blockchains:
Encryption {key}
Timestamping and consensus {stamp}
Verification {check}
TRUST in terms of transparency, efficiency and free access or are people something lying, cheating and stealing, have (therefore)
inefficient means in place and abuse their power to no let others participate.

Expert question: What is the accidental part of the blockchain discovery? -> Answer: The (later customized ‘op_return’) data field of a
transaction.
