Part 2/9:
Andreas opens by asserting that Bitcoin should be classified as an "open blockchain," highlighting its core characteristics: global reach, decentralization, and permissionless participation. Unlike many so-called blockchains that operate within permissioned environments, Bitcoin’s open blockchain allows anyone worldwide to participate, innovate, and verify transactions without needing approval from central authorities.
This openness is fundamental to Bitcoin’s identity. It emphasizes transparency and inclusivity, enabling a system that remains resilient against censorship and centralized control.
