Web3 represents the evolution of the World Wide Web from Web 2.0 to Web 3.0, and is changing to a decentralized version.
We use technologies like blockchain, smart contracts, and cryptocurrencies to create a more open, free, and secure internet ecosystem.
Web3 does not only refer to blockchain technology, but also includes the construction of decentralized applications (dApps) that operate by utilizing new technologies such as blockchain networks, decentralized storage, and digital identities.
A decentralized system is a network where control and decision-making are not concentrated in a single entity or authority, but are distributed among its users.
This allows all participants to have equal voice and power in how the system operates and evolves.
A clear example is Bitcoin, where new Bitcoin transactions and generation are managed collaboratively across a network without the need for a central bank or government.
Blockchain is a technology that functions as a decentralized register where transactions are chained together thanks to cryptography and recorded in secure blocks.
Blockchain is the technology behind cryptocurrencies like Bitcoin and Ethereum.
Its main characteristic is decentralization, which ensures data integrity and transparency without requiring a central authority.
Bitcoin is a type of digital money that allows you to buy things or send money to people on the internet without intermediaries.
Imagine having coins that you can use to buy video games or pay friends on the internet.
You don't need to use a credit card or go through a bank. It's like cash through the internet.
Let's say you want to buy pizza over the internet and decide to pay with Bitcoin or other currency. What you do is send a small amount of “digital money” directly to the pizzeria, without having to provide a credit card number or go through a bank.
The pizzeria will receive your payment almost instantly, and you will receive your pizza at home. All of this is done safely and quickly, using a computer or mobile phone.
This is where the term “read, write, own” was born.
Web 1.0 only allowed receiving (reading) information.
Web 2.0 made it possible to receive and send (write) information.
Web 3.0 also allows you to own one.
An NFT (Non-Fungible Token) is like a unique digital possession that cannot be exchanged for anything else because nothing is the same in the world.
It's like a collector's card, but it's a digital edition with a special certificate showing that you're the sole owner.
Even if someone makes a copy of your digital sticker image, only you have a certificate proving that the original is yours.
1 Bitcoin is exactly like any other Bitcoin, but 1 NFT is not exactly the same as any other NFT.
Imagine an NFT like a title register for your home. NFTs represent that home and indicate that you are the rightful owner. When buying a home, you acquire ownership rights to real estate. An NFT is like a right to its ownership.
