I included this link in my reply to you:

Proof of blockchain fair sharing is a draft Bitcoin protocol change proposal by Iain Stewart, with the goal of allowing the network to continue to settle on a sensible consensus blockchain even when subject to a considerably-greater-than-50% attack.

The protocol is under construction. The following description is a "teaser", establishing its basic flavour and sketching how it exploits an asymmetry in the goals of the honest (<50%) and malicious (>50%) miners to avoid the usual reductio ad absurdum argument against any protocol surviving a >50% attack.
