“The 1st ever ‘blockchain’ was the Samaritan alphabet on stone.Transcriptions on stone back then was considered immutable.Understanding the Newtonian physical properties of stone allowed ancients to timestamp information through energy expenditure (proof of work).

The #Bitcoin Time Stamping feature combined with the energy expenditure through Proof Of Work follows principles of Newtonian physics and creates a decentralised digital immutable Blockchain.”
