No, Factom runs on top of Bitcoin chain. Guardtimes solution is built on their
"keyless signature infrastructure"
https://github.com/GuardTime/libksiMy impression, based on cursory perusal of the code is that theirs it is not a blockchain
but more like linked list of hashes. Nothing to do with Eth or smart contracts either.
Fine, I just wanted to make the point that if it comes down to a serious solution / app -> Some (open source) chain code is just forked / copied, not adopted.
IMO R3 is expected to do exactly this as well, so after they've played around enough, they'll build own stuff.
