Traditional cybersecurity relies on information secrecy—passwords, encryption keys, security through obscurity. Bitcoin introduces cyber-physical security: protection through thermodynamic cost that cannot be bypassed with knowledge alone.
This category explores the paradigm shift from hackable information security to unhackable cyber-physical defense, examining attack vectors, consensus security, and the electro-cyber dome concept.
Security based on energy expenditure rather than information secrecy—fundamentally unhackable.
Proof-of-work creates defensive shield protecting digital infrastructure through physical cost barriers.
As hashpower increases, attacks become more expensive—creating self-strengthening defense system.
Bitcoin's core protocol has never been hacked in 16+ years. Learn why Bitcoin's proof-of-work security makes network-level attacks economically impossible while understanding real vulnerabilities.
Comprehensive guide to Major Jason Lowery's electro-cyber dome concept—how Bitcoin's proof-of-work creates a defensive shield in digital space analogous to military air defense systems.
Step-by-step guide to evaluating Bitcoin's security model. Analyze hash rate, economic attack costs, decentralization, and thermodynamic security guarantees.
Comprehensive analysis of the paradigm shift from information-based cybersecurity to thermodynamic cyber-physical security, exploring how Bitcoin's proof-of-work creates unprecedented digital defense mechanisms.
Compare Bitcoin's proof-of-work security model to traditional information security. Understand how thermodynamic security differs from access control and encryption-based approaches.
A 51% attack occurs when an entity controls majority Bitcoin mining power. Learn why such attacks cost $20-30 billion, what damage they can cause, and why they remain economically impractical.
