Frequently Asked Questions
What are the most important blockchain concepts for beginners to understand?
For beginners, focus first on understanding decentralized networks, cryptographic security, consensus mechanisms (like Proof-of-Work vs. Proof-of-Stake), smart contracts, and the difference between coins and tokens. These fundamentals provide context for more advanced topics.
How can I safely store my cryptocurrency?
Always use reputable wallets (like hardware or properly configured software wallets), enable two-factor authentication, never share private keys, and be wary of phishing attempts. For small amounts, mobile wallets are convenient, but larger holdings belong in cold storage.
What's the difference between blockchain and cryptocurrency?
Blockchain is the underlying distributed ledger technology that enables secure, transparent record-keeping. Cryptocurrency refers to digital assets (like Bitcoin or Ethereum) that use blockchain technology for monetary transactions. All cryptocurrencies use blockchain, but not all blockchains have cryptocurrencies.
Are blockchain transactions truly anonymous?
Most blockchains are pseudonymous rather than anonymous—transactions are publicly visible but tied to wallet addresses rather than personal identities. Some networks like Monero offer enhanced privacy features, but complete anonymity is difficult to achieve while complying with regulations.

How do decentralized applications (DApps) differ from regular apps?
DApps run on peer-to-peer blockchain networks rather than centralized servers, giving users more control over their data and digital assets. They typically feature transparent code, token-based economies, and operate without single points of failure—though they may sacrifice some speed and scalability compared to traditional apps.
What are gas fees in blockchain transactions?
Gas fees represent the computational costs of processing transactions or smart contracts on networks like Ethereum. Users pay these fees to compensate validators for securing the network. Fees fluctuate based on network demand—learning to optimize gas settings can significantly reduce transaction costs.
