Frequently Asked Questions
What is the difference between Bitcoin and Ethereum?
Bitcoin was designed primarily as a decentralized digital currency. Ethereum extends this concept by allowing developers to build and run smart contracts and decentralized applications on its blockchain.
How can someone start investing in blockchain technology?
Beginners can start by using reputable cryptocurrency exchanges to purchase digital assets or by investing in blockchain-focused ETFs and public companies. It’s important to research and understand the risks involved. 👉 Explore reliable investment platforms
Are blockchain transactions truly anonymous?
Not entirely. Most blockchain transactions are pseudonymous—public addresses are visible, though not directly linked to real-world identities. Some networks offer enhanced privacy features.
What are smart contracts?
Smart contracts are self-executing contracts with terms written into code. They automatically execute when predefined conditions are met, reducing the need for intermediaries.
Can blockchain be used beyond cryptocurrency?
Absolutely. Blockchain is being used in supply chain tracking, healthcare data management, voting systems, digital identity verification, and much more.
What is Web3?
Web3 refers to a new iteration of the internet built on decentralized protocols, often using blockchain. It aims to give users greater control over their data and online interactions. 👉 Learn more about Web3 tools
Blockchain is more than a technology—it’s a movement toward decentralization, transparency, and user empowerment. The individuals mentioned here represent just a fraction of those contributing to this fast-evolving ecosystem. Whether through code, capital, or advocacy, each plays a part in building the foundation of a decentralized future.
