1.BlockchainThe distributed ledger

“The Blockchain is a way of

maintaining consensus on a decentralised distributed network. If you have lots of disparate parties with no central authority, how do

you make sure they all agree?

Blockchain as an historical recordThe Blockchain is a file which contains the historical truth since the beginning of its times. Imagine it as a notary writing all the things which happen in the world, every one of them.

In a Blockchain,

every node is a notary

“The first Blockchain application is

Bitcoin, a cryptocurrency. It uses a Blockchain to store all the

transactions, which are verified and stored by every node.

Cryptocurrencies are the smallest part

Smart Contracts

Distributed applications

Distributed Autonomous

Organizations

Proof of Existence

Storage sharing

Process Automatization

2.Smart ContractsAgreement in the Blockchain

“A Smart Contract is a program

runned in a Blockchain. Every node in this Blockchain maintain and

update this program’s state ensuring its conditions’

accomplishment.

A world of possibilities

With Smart Contracts we’re able to build:◎ Cryptocurrencies◎ Distributed

Applications (DAPPs)

◎ Distributed Autonomous Organizations (DAOs)

“A DAPP is a Distributed Application,

an application which runs in a Blockchain. It combines Smart

Contracts and web technologies to give an easy to use interface and a

nice user experience.

“A DAO is a Distributed Autonomous

Organization, an organization based in the Blockchain. It

combines Smart Contracts and custom coins to build this self driven

organizations.

Thanks!Any questions?
