Pragmatic definition of consensus for light clients

The discussion highlights the necessity of implementing mechanisms that would allow miners to explicitly advertise the rules they enforce continuously. This could potentially be achieved by using methods such as displaying their client IDs or a bitmap field that details the rules, forks, and Bitcoin Improvement Proposals (BIPs) they support. The implementation of such mechanisms would facilitate an on-chain negotiation process regarding the enforcement of new rules or the discontinuation of old ones. This approach aims to reduce the recurrent controversies by moving away from the binary expectation that node operators must either enforce all rules or none. By making these changes, the entire ecosystem could benefit from greater transparency and reduced confusion about rule enforcement among miners, ultimately leading to a more stable and predictable blockchain environment.
