Not at the moment and, unfortunately, I'm not sure if this is really doable (although we may be able to, e.g., track the top X most popular blocks). Like bittorrent, IPFS breaks files into blocks. However, unlike bittorent, IPFS treats all files as a part of a single, global filesystem (basically, one huge torrent).
Bittorrent aggregates statistics at the torrent level (it doesn't track statistics per block). However, in IPFS, the analogue would be aggregating statistics at the node level (what we already do).
So, the question is, at what level should we track statistics. We could do track statistics for each block independently but this is likely to lead to quite a bit of overhead. Alternatively, we could try to aggregate statistics at, e.g., pin roots. However, we'd then need to keep track of which blocks are referenced by which pins at all times (arguably more expensive in terms of disk space).
