Part 7/9:
The criticisms levied against Bitcoin highlight the limitations of relying solely on hash power for security. If BTC boasts significant hash power but fails to address node connectivity and transaction efficiency, the security asserted by its advocates may fall flat.
Moreover, the oversimplified argument that a powerful hash rate suffices as proof of security ignores critical vulnerabilities associated with double spending and insufficient transaction processing capabilities. Events where an attacker attempts to double-spend might fool a network, but the connections and verification processes among legitimate nodes remain paramount.
