Unit 2: Foundations of Ownership, Security Related Concepts in Blockchain

  Unit 2: Foundations of Ownership, Security Related Concepts in Blockchain Foundations of Ownership In traditional systems, ownership is often documented and verified by centralized authorities (e.g., land registries, banks). In blockchain, ownership is established and proven through cryptographic methods, primarily using public-key cryptography . Public and Private Keys: Each user on a blockchain network has a unique pair of cryptographic keys: a public key and a private key. The public key acts as an address, similar to an account number, visible to everyone. It's used to receive assets or data. The private key is a secret code that grants control over the assets associated with the public key. Only the person possessing the private key can authorize transactions from that address. Digital Signatures: To prove ownership or authorize a transaction, a user digitally "signs" a message or transa...

Unit-1 Foundations of Software Systems and Blockchain

  Unit 1: Foundations of Software Systems and Blockchain 1. Layers of a Software System Software systems are typically organized into layers to separate responsibilities, improve maintainability, and allow independent scaling. Common layers include: Presentation Layer: Handles user interface (UI) and user interaction (e.g., web pages, mobile app screens). Application/Business Logic Layer: Contains the core business rules and orchestrates data flow, processing user requests (the "brains" of the application). Data Access Layer (DAL): Provides an interface for the application to interact with data storage, abstracting database complexities. Data Layer: The actual persistent storage for data (e.g., databases, file systems). This layered approach promotes modularity and makes systems easier to develop, test, and update. 2. Integrity Integrity in software systems ensures that data is accurate, consistent, and trustworth...
