I started a thread here recently:
https://bitcointalk.org/index.php?topic=1805042.0The topic was a coin similar burst, but the space used is usable by other people. (and it burns more coins if they become too cheap to help keep the value stable or ascending)
iamnotback assured me that using Proof of Storage cannot be made secure, and that Burst was nothing but rubbish.
I am interested to read the replies to this thread, in particular any comments about the viability of proof of storage.
*edit*
Look who turned up while I was writing that post lol...
