4. “ They say that it’ll hit us on Hogswatchnight and the seas will boil and the countries of the Disc will be broken and kings will be brought down and the cities will be as lakes of glass,’ said the man. ‘I’m off to the mountains.’ ‘That’ll help, will it?’ said Rincewind doubtfully. ‘No, but the view will be better. ― Terry Pratchett, The Light Fantastic

8. SEALING ➤ Earlier the third-party/ middleman gave us the trust that whatever they have written in the register will never be altered. In a distributed and decentralized system like ours, this seal will provide the trust instead. Source: „WTF is The Blockchain?“ -Mohit Mamoria
