I don't know the answers to your questions.  I only just remembered that I had ran the NAS client and bought some coins back in April of last year, so I was curious as to the health of the coin.

Do you remember when was the last time you ran the NAS client?  If you run it now, do you connect to any peers?

My copy of the NAS blockchain is nearly a year old, and the two peers I have in my client's list are apparently no longer running the software.

If your blockchain is relatively up to date, could you zip it up and share it on mega (https://mega.co.nz/) or dropbox?  I'd like to take a forensic look at the NAS blockchain.

Thanks.
