Your guide to the Ethereum blockchain
Unlike most software of traditional applications, smart contracts don’t run on your computer or somebody’s server: they live on the Ethereum network itself.
This means that to be able to interact with them, first they have to be deployed to a blockchain.
During development of your DApp you can deploy it on:
Smart contracts are a way to decentralize the controlling logic and payment functions of applications.
You can think of a smart contract replacing a server-side (“backend“) component in a regular application.
The most popular languages for writing smart contracts on Ethereum are Solidity (inspired by C++, Python and JavaScript) and Vyper (based on Python).

Client-side interface of a DApp can use standard web technologies (HTML, CSS, JavaScript, etc.).
Typically are used a JavaScript convenience libraries, that provide an API to make integrations with smart contract (backend) easier for developers.
By choosing hosting / domain for a DApp, there are options:
What are DApps and how they differ from classical Apps?
Blockchain and smart contract development are still relatively new and highly experimental.
They require a different engineering mindset than traditional web, or app development where ‘move fast and break things’ has become the norm. Blockchain development is much more like hardware, or financial service development.
Each aspect of any application can be somewhat centralized <-> or decentralized.
DApp is an application that is mostly or entirely decentralized.
Every block contains a list of transactions. In Ethereum there are two kinds of transactions between accounts:

What is Decentralized Finance?
Decentralized finance (DeFi) are financial smart contracts, decentralized applications (DApps), and protocols built on Ethereum, that can be pieced together like a Lego.
Financial DApps are one of the hottest use case of Ethereum at the given moment.
Why use DeFi?
As the size and complexity of our economies grew, central authorities (i.e. governments, central banks, corporations) gained more power as more people placed trust in them. However we often have very little say in how corporations handle our investments, or even how our governments manage the economy.
DeFi aims to create a financial system that’s open to everyone and minimizes one’s need to trust and rely on central authorities. Technologies like the internet, cryptography, and blockchain give us the tools to collectively build and control a financial system without the need for central authorities.
You just need an internet connection and will to learn to use DeFi.
What can you do with DeFi?
There are several use cases of DeFi:
– Lending – lend or borrow tokens and also earn passive income
– Decentralized exchanges (DEXes) – buy, sell, or trade cryptocurrencies or tokens
– Derivatives – trade nearly any asset using synthetic pricing
– Payments – transfer funds by using payment channels
– Assets – manage tokenized physical assets such as gold
– Prediction / Betting markets – bet on the outcome of any event
– Insurance – insure yourself by sharing risk with a community of people
– Yield Farming – use DApp and earn token for it
How to get involved in DeFi?
