Let's Web3

What is Web3?

Web3 (also known as Web 3.0) is an idea for a new iteration of the World Wide Web which incorporates concepts such as decentralization, blockchain technologies, and token-based economics. Some technologists and journalists have contrasted it with Web 2.0, wherein they say data and content are centralized in a small group of companies sometimes referred to as "Big Tech". The term "Web3" was coined in 2014 by Ethereum co-founder Gavin Wood, and the idea gained interest in 2021 from cryptocurrency enthusiasts, large technology companies, and venture capital firms.

From Web1 to Web3:

- Web1: Basic HTML,e-mails. Users could only read the information, without the chance of direct interaction. Web1 was also called “Static Web”.

- Web2: Informative and interactive. The user who was once just a passive actor, became the holder of the creation and management of online content, building new processes and interactions. Web2 was also called "Collaborative Web".

- Web3: Decentralized, private and secure. Users control their own data, identity and destiny. No entity would be able to collect data without the user's consent, nor limit or censor anyone's access.

Blockchain Network-Layer 1

Blockchain Network is the network base on Blockchain technology. Layer 1 refers to a base network and its underlying infrastructure. Layer-1 blockchains can validate and finalize transactions without the need for another network.

Blockchain Network-Layer 2

Layer 2 is a collective term to describe a specific set of Layer 1 scaling solutions.The main goal of most Layer 2 is to increase transaction speed (faster finality) and transaction throughput (higher transactions per second) without sacrificing decentralization or security.

Infrastructure

Infrastructure is the technologies, tools, and solutions developers need to build and operate web3 apps.It connects developers and blockchain networks, like node providers,Web3 API providers,Web3 wallets,blockchain explorers and so on.

Cryptocurrency Exchanges

Cryptocurrency exchanges function similarly to online brokerage platforms, providing you with the tools you need to buy and sell digital currencies and tokens like Bitcoin, Ethereum. It is the gate connecting the real world and the Web3 world.

Dapp

Decentralized application is like a digital app found on any smartphone or laptop, with the additional feature of employing blockchain technology to keep users' data out of the hands of the organizations behind it. Just like cryptocurrency is decentralized money, dapps are decentralized apps.
