2. Blockchain Technology: Fundamentals
2.1 What is Blockchain?
Blockchain is a type of distributed ledger technology (DLT). Instead of storing records in a central database, blockchain spreads identical copies of data across a network of computers (“nodes”). When a new transaction occurs, it’s packaged into a “block,” cryptographically linked to the previous block, and replicated across all nodes. This creates a permanent, chronological “chain” of records.
2.2 Key Features for Defense
- Decentralization: No single point of control or failure. This improves resilience, especially in contested environments.
- Immutability: Once a record is added, it can’t be altered or deleted without consensus from the network.
- Transparency: All authorized participants see the same data, reducing miscommunication and fraud.
- Security: Cryptography ensures only authorized parties can access or write data.
- Smart Contracts: Lines of code that execute automatically when pre-set conditions are met, enabling automation of complex processes.
