What happens if a BIP does not receive 95% confidence from miners?

It will automatically be implemented.
It will be rejected.
It will be put into a waiting list.
It requires further community discussion.

The correct answer is: It will be rejected.

If a BIP (Bitcoin Improvement Proposal) does not receive 95% confidence from miners, it means that there is insufficient consensus within the mining community to implement that specific proposal. The 95% threshold is a guideline that indicates a significant majority of miners support the change before it can be incorporated into the Bitcoin protocol. Without this level of agreement, the proposal does not move forward and is effectively not adopted into the network's codebase. The notion of consensus is fundamental in decentralized systems like Bitcoin, where multiple independent parties must agree on changes to ensure stability and reliability. In this context, proposals are crafted to enhance or modify the network, and without the necessary support from a substantial majority, the protocol remains unchanged. Subsequently, the proposal may be revisited in the future or adjusted before seeking approval again. This highlights the importance of collaborative decision-making in governing the Bitcoin network, ensuring that only well-supported changes are made for the overall benefit of the community and the network.
