The 7 Essential CCS339 Questions Explained
- How does blockchain achieve decentralization and why is it revolutionary?
Blockchain eliminates central authorities through distributed ledger technology (DLT), where transactions are verified by network nodes. This prevents single-point failures and censorship, enabling trustless systems. Revolutionarily, it allows peer-to-peer value transfer without intermediaries – foundational to cryptocurrencies like Bitcoin.
- What cryptographic principles secure blockchain transactions?
Two core mechanisms provide security: Hash functions (SHA-256) create immutable data fingerprints, while asymmetric cryptography uses key pairs (public/private) for digital signatures. Together, they ensure data integrity, authentication, and non-repudiation – making tampering computationally infeasible.
- How do consensus algorithms like PoW and PoS differ in maintaining blockchain integrity?
Proof of Work (PoW) requires miners to solve complex puzzles, consuming significant energy but providing battle-tested security (Bitcoin). Proof of Stake (PoS) selects validators based on staked cryptocurrency, offering energy efficiency (Ethereum 2.0). Both prevent double-spending but involve trade-offs in scalability and decentralization.
- What are smart contracts and how do they enable dApps?
Smart contracts are self-executing code on blockchains (e.g., Ethereum) that automate agreements when conditions are met. They form the backbone of decentralized applications (dApps), enabling complex functions like DeFi lending and NFT trading without intermediaries, while inheriting blockchain’s security and transparency.
- How do public and private blockchains differ in use cases?
Public blockchains (Bitcoin, Ethereum) are permissionless and ideal for transparent, censorship-resistant systems. Private blockchains (Hyperledger) restrict participation, prioritizing speed and privacy for enterprise solutions like supply chain tracking. Hybrid models offer balanced approaches for specific business needs.
- What are the major scalability challenges in blockchain networks?
The “blockchain trilemma” highlights the difficulty in achieving scalability, security, and decentralization simultaneously. Solutions include Layer-2 protocols (Lightning Network), sharding (splitting databases), and alternative consensus mechanisms – each addressing throughput limitations while managing trade-offs.
- How might blockchain disrupt traditional finance through DeFi?
Decentralized Finance (DeFi) uses blockchain to recreate financial services (lending, trading) without banks. By enabling programmable money, reducing intermediaries, and increasing accessibility, it challenges legacy systems but faces regulatory and volatility hurdles before mainstream adoption.
