I've found they've been extremely quiet for the whole year, or longer. They did recently send out an email talking about their progress and showed some demos, but I just skipped over the email actually, didn't look into it to see if they talked about their POS 'Proof of [stuff]'.

I just dug it up and they say Proof of Replication is going great. But don't show anything, they promise to open the code in the 'coming months' so people might see what progress has been done if any.

No progress was mentioned for Proof of Spacetime.

Edit: The link to their update, the only substantial one since the ICO last year I think... https://filecoin.io/blog/update-2018-q1-q2/

Yeah, this is the kind of stuff I'd seen that had made me reluctant to talk about FileCoin as "IPFS has found a way to..."

They wrote a paper describing a plausible system that - if it existed - could do a thing. They've been much less successful actually finding a way to implement it.
