Core Concepts
What is a Blockchain?
A blockchain is a chain of "blocks" containing transaction data, linked and secured using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. This creates an immutable record that can't be altered without changing all subsequent blocks.
Block Structure
Key Properties
🔗 Immutability
Once data is recorded, it's extremely difficult to change
🌐 Decentralization
No single point of control or failure
👁️ Transparency
All transactions are visible to network participants
🔐 Security

Frequently Asked Questions
What is blockchain technology?
Blockchain is a distributed ledger technology that records transactions across multiple computers in a way that makes them secure and tamper-proof. Each block contains transaction data and a cryptographic hash linking it to the previous block, creating an immutable chain. The decentralized nature means no single entity controls the network, making it resistant to fraud and censorship. Blockchain is the foundation technology that powers all cryptocurrencies.
What are gas fees and why do they exist?
Gas fees are transaction costs paid to network validators (miners or stakers) for processing and validating transactions on blockchain networks like Ethereum. They compensate validators for computational work and help prevent spam transactions. Gas fees vary based on network congestion - higher demand means higher fees. Users can often choose to pay higher fees for faster processing or lower fees for slower processing.
How do blockchain transactions work?
Blockchain transactions follow this process: 1) A user initiates a transaction, 2) The transaction is broadcast to the network, 3) Network nodes verify the transaction is valid, 4) Miners or validators compete to add the transaction to a block, 5) The transaction is confirmed and added to the blockchain. This creates a permanent, immutable record that can't be altered without changing all subsequent blocks.
What is the difference between public and private blockchains?
Public blockchains (like Bitcoin and Ethereum) are open to anyone and are decentralized, with no single entity controlling the network. Private blockchains are controlled by a single organization and restrict access to authorized participants. Public blockchains offer transparency and censorship resistance, while private blockchains provide more control and privacy for enterprise applications.
How does blockchain ensure security?
Blockchain ensures security through multiple mechanisms: 1) Cryptographic hashing makes it extremely difficult to alter data, 2) Decentralization removes single points of failure, 3) Consensus mechanisms ensure network agreement on valid transactions, 4) Immutability means once data is recorded, it cannot be changed, 5) Transparency allows all participants to verify transactions, 6) Public-key cryptography secures user identities and transactions.
