I am talking specifically about what Peter Todd talks about here:

https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-December/012103.html

I have been away from the space for a bit and would like to catch up on things, and I was hoping somebody could link me to any IRC chats or other things not just in the mailing list for me to read over.

I am not particularly worried about this, because I think there are enough fully validating nodes that invalid blocks will be caught, but still, it is a new economic incentive towards less security, which is of course a potential issue.

I'm sure it's already been dealt with or is being dealt with, and I am hoping somebody can link me to the most recent advances in that regard, so I can get all caught up.

Thanks!
