The document discusses the history and basics of blockchain technology. It explains that blockchain was invented in 2008 and allows digital information to be recorded and distributed, but not edited, deleted or altered, creating an open and transparent system. The document outlines some key applications of blockchain beyond cryptocurrencies, including for banking, voting, supply chain management, and healthcare. It argues that blockchain adds a trust layer that can disrupt existing industries and transform how business is done across many sectors in the coming years.

2. What is blockchain?
Will it really change enerything?

3. The very beginning: 2008
Satoshi Nakamoto invented bitcoin and the
blockchain.
For the first time in history, his invention made
it possible to send money around the globe
without banks, governments or any other
intermediaries
A trustless environment to trust each other and among businesses.

4. The Basics

Timestamping Consensus building

5. Blockchain bring us…
• Data updated near real time
• Information integrity + timestamped
• Data auditability + immutability
• As robust as distributed architectures
• As secure as other cryptographic solutions
• Transparency of transactions

6. But the most important thing is
BLOCKCHAIN solves governance
issues from the technology

7. How it Works?

9. Beyond transactions… programable blockchains

10. Smart contracts Work in three steps

pragma solidity ^0.4.0;
contract SimpleToken {
/* This creates an array with all balances */
mapping (address => uint256) public balanceOf;
/* Initializes contract with initial supply tokens to the creator of
the contract */
constructor (uint256 initialSupply) public {
balanceOf[msg.sender] = initialSupply; // Give the creator all
initial tokens
}
/* Transfer tokens */
function transfer(address _to, uint256 _value) public {
balanceOf[msg.sender] -= _value; // Subtract from the sender
balanceOf[_to] += _value; // Add the same to the recipient
}
}
