Blockchain FAQ
Q: How does blockchain differ from traditional databases?
A: Traditional databases are centralized and controlled by single entities, while blockchains distribute data across networks with no central ownership.
Q: Is blockchain only useful for cryptocurrency?
A: No. While cryptocurrency was the first application, blockchain now serves supply chains, healthcare records, voting systems, and hundreds of other use cases.
Q: What prevents someone from altering blockchain data?
A: The combination of cryptographic hashing, network consensus rules, and distributed verification makes data tampering computationally impractical.
Q: Are private blockchains different from public ones?
A: Yes. Public blockchains (like Bitcoin) are open to anyone, while private blockchains restrict participation to authorized entities, often used for enterprise solutions.
Q: How energy-intensive is blockchain technology?
A: It varies. Proof-of-Work systems (like Bitcoin) consume significant energy, but newer Proof-of-Stake blockchains use 99% less energy while maintaining security.
Q: Can blockchain scale to handle global transaction volumes?
A: Scaling solutions like layer-2 networks, sharding, and sidechains are dramatically improving throughput – some networks now process 100,000+ TPS.
