Part 19/19:
Bitcoin’s consensus mechanism exemplifies a marriage of cryptography, game theory, and distributed network architecture—creating a system that is secure, resilient, and self-regulating. Its reliance on proof-of-work aligns economic incentives with network integrity, making malicious attacks prohibitively expensive and maintaining a transparent, verifiable ledger open to anyone. As the ecosystem continues to evolve, scalability and protocol innovation remain active areas of research, promising a future where Bitcoin could support a truly global, decentralized financial infrastructure.
