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.
