What is Blockchain?
Blockchain is a decentralized digital ledger that records transactions across many computers, ensuring that the record cannot be altered retroactively without the alteration of all subsequent blocks.
How Blockchain Works
Transactions are packaged into blocks and added to a chain in chronological order. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data, which is confirmed by network participants (nodes).
Applications of Blockchain
- Cryptocurrency: Bitcoin and other cryptocurrencies rely on blockchain for security.
- Smart Contracts: Automated contracts with terms directly written into code.
- Supply Chain: Enhances transparency and traceability within supply chains.
- Healthcare: Secures patient records and reduces fraud.
Challenges
Despite its benefits, blockchain faces challenges like scalability, energy consumption, and regulatory issues.
FAQs
Is blockchain secure? Yes, blockchain's decentralized nature and cryptographic techniques make it highly secure.
Can blockchain be hacked? While theoretically possible, hacking a blockchain is extremely difficult due to its decentralized nature.
