An educational overview of blockchain fundamentals, explaining how distributed ledgers work, their advantages over centralized databases, and comparisons of major blockchain platforms including Bitcoin, Ethereum, and Stellar.
This article provides a comprehensive introduction to blockchain technology, tracing its conceptual origins from traditional ledgers to modern distributed systems. It explains the core problem blockchain solves—enabling multiple independent parties to maintain a shared database without central authority—and describes the technical mechanism of how blockchain networks achieve consensus through cryptographic verification. The article then contextualizes Stellar within the broader blockchain landscape, highlighting how Stellar's Proof-of-Agreement consensus mechanism differs from Bitcoin's Proof-of-Work and Ethereum's Proof-of-Stake, while emphasizing Stellar's focus on fast, low-cost payments and real-world asset integration.
