Imagine we were at the beginning of the 2000s, when popular websites like Wikipedia, YouTube, blogs, forums, chat, PayPal, and social networks emerged. At that time, people began to realize how engaging Web 2.0 technology was. The main characteristic of Web 2.0 is its interactivity, where users could comment on forums, create their own blogs, interact socially, and even send money without going through banks.

The hallmark of Web 2.0 is user participation and interactivity, but it still used centralized servers controlled by the companies owning the servers or applications.

The next big development came in 2009 with the launch of Bitcoin, which was actually the starting point for Web 3.0 technology. At that time, few realized that Bitcoin and the blockchain technology behind it would become so popular.

Then, in 2014, Ethereum emerged with its smart contract technology. I still remember the early days of building smart contracts using the web3.js library.

This was the dawn of Web 3.0, characterized by features like decentralization, data and digital identity ownership, smart contracts, openness and transparency, security and privacy, decentralized applications, decentralized governance, and the use of a wallet as a password replacement for access.

The key aspect of Web 3.0 and blockchain is decentralization, giving users full control over their data.

But what is blockchain?

Imagine a large ledger shared by many people. Everyone can write something in it, and everyone can see it. Each entry cannot be altered or deleted because it's organized in a sequence protected by very robust mathematical calculations. You can transfer money on the blockchain without intermediaries, with transfers that can be done in seconds, compared to cross-border bank transfers which can take days.

P2P (Peer-to-Peer) Transfer

In Web 3.0, direct peer-to-peer transfers eliminate the need for intermediaries like banks, PayPal, or VISA. If you want to send Bitcoin to a friend, just enter their wallet address, and the transaction will be verified and settled directly on the blockchain without third-party intervention. The transfer process in Ethereum is even faster, just seconds.

Crypto Wallet

A wallet in Web 3.0 doesn't store money directly but holds addresses and keys to move assets on the blockchain. Similar to having a debit card, this wallet provides access and control over digital assets.

Smart Contract

Imagine a contract in the physical world with specific rules. In blockchain, a smart contract is a contract written in programming logic, removing the possibility of multiple interpretations.

Examples of Smart Contract Applications:

  • Funding for Children: You could save an amount of money for your child to start a business at age 24. When your child turns 24, they automatically receive the funds to start their business, done without intermediaries and errors.
  • Entrepreneurship and Inheritance: You can set up funds for heirs to only be accessible after meeting certain criteria like age or achievement, ensuring the assets are used according to your wishes.
  • Waqf and Land Titles: Smart contracts can be used to manage waqf, where endowment funds or assets are automatically distributed according to pre-set rules. For land titles, smart contracts can ensure that land ownership cannot be changed without the consent set in the contract.

Implications of Web 3.0

Web 3.0 offers a new paradigm by shifting ownership and control from centralized entities to individuals. This technology changes how we view identity, assets, and online activities, without relying on large tech companies or centralized authority regulations. Although still in its early stages, Web 3.0 is beginning to disrupt traditional industries like finance with DeFi, gaming with P2E, and social media with decentralized applications.

If you want to glimpse the future of the internet, now is the perfect time to start exploring Web 3.0. This technology is the first step towards a new generation of the internet.
