Abstract

This RSKIP proposes an improvement to the Fork Detection Data present in merge-mining tags (used by the Armadillo Fork Detection System). The tag is extended to include the cumulative work of the chain. This allows more accurate 51% attack detection.

You can read RSKIP223 [here](https://github.com/rsksmart/RSKIPs/blob/master/IPs/RSKIP223.md).
