Part 6/9:
For Bitcoin to effectively function, particularly in cases of double-spending, nodes must be able to communicate and verify transactions efficiently. Losing the ability to transmit information instantaneously could lead to vulnerabilities. Bitcoin's transaction verification system involves a complex web of nodes that need to confirm transactions to prevent fraud effectively.
CS theories indicate that the best network designs ensure nodes are well-connected, maintaining robustness even under attack or if some nodes go offline. This contrasts with Bitcoin's design, where keeping block sizes smaller to accommodate more nodes can inadvertently jeopardize the network's ability to communicate effectively.
