Here is my summary of the book What is blockchain?

• Blockchain principles

  • Start with the story of Changpeng Zhao - a blockchain billionaire in less than a year.

  • He created Binance in 2017 a flatform to transfer bitcoin and altcoins.

    • Where do we have inefficient intermediaries? Who can we eliminate from our supply chain? “Going direct to the customer” has always been a way to save money for both producers and consumers.
    • where can we eliminate steps in our supply chain?  Where can we replace a centralized record keeper with a decentralized ledger? Where can we eliminate an intermediary? That’s where a blockchain solution is often hiding.

  • Code, Not Contracts

    • A contract is paperwork that records a transaction between two or more parties.
    • A smart contract is computer code that establishes agreements between parties and then executes the transaction when certain conditions are met, without the need for a third party.
