monero win64 #204352 block
I understand that everybody wants to be cautious with unapproved blockchains but I also wanted to get my wallet synced and not wait any longer so I downloaded the above torrent file.
I can tell you that it worked perfectly for me and I sent some XMR to poloniex once I was on this chain and the payment has arrived. So all good for me.
My seedbox is seeding this chain on 500mbit if you want to grab it.
If you want to be super-super-cautious then wait for the devs to release an approved blockchain, which I don't understand why this hasn't happened yet.
That's really odd. That blockchain.bin didn't work for me on Windows 7 64-bit when I downloaded it earlier this morning, so I ended up having to use other means.
