Is downloading a torrent version of the blockchain a safe alternative? What assurances are there that the file you download this way is the real thing?

Downloading from a torrent is the best approach if you are able to do it. You don't need to worry about getting a bogus blockchain because the bitcoin client contains built-in checkpoints. So even if somebody gives you a blockchain which is internally consistent, the client will still reject it because it doesn't match its checkpoint values.

I run BitTorrent to seed the blockchain torrent and there is never any drop in the demand. I also run a full bitcoin node and that also runs at capacity feeding blocks to peer nodes. So there must be a lot of people installing Bitcoin-Qt for the first time Cheesy

You can run bitcoin-qt with the rescan (-rescan) option and check the blockchain. I do this at least once a month just to make sure my blockchain is good.

Quickest way is to download as a torrent file - is about 9 gb or torrent and this includes the blockchain until about one month ago.
Move the downloaded torrent file - bootstrap.dat - to the bitcoin folder - C:\users\me\appdata\roaming\bitcoin on win8, then start the qt client and it automagically builds the database (takes about 2 hours) and then downloads the last months transactions.

Mine is the 15.3GB and that is just the amount in my block's folder, which is where the blockchain is housed. The real answer is cause different file system uses different ways of measuring a gb. I am on Mac so I can measure base 10 or base 2. Mine was measured in base 10 making 1000MB == 1gb, in base 2 mine is 14.3GB. Sorry for the confusion.

Also some people maybe a couple blocks ahead or not depending on who they are connected too as well.

Thanks.
didn't thought of it
thus we have to compare the amount in bytes

could it also depends on the the size of a disk's cluster and files fragmentation level?

Just curious, why do everyone report a different size?
I can see 14.2, 14.4 and even 15.3 GB, and there is something like 10% difference. Why and how?

depending on the time of install and use it can contain different logs, peers, debug data, etc.
wallet size are different too

Currently my wallet is just a few MB, and so as the debut log and peers.dat

I don't think these files will grow to something like a GB, or will them? Shocked

Do you have Bitcoin-QT installed as your wallet?

I gave up downloading the bootstrap from source forge, letting the client do it now, might be done by the end of the weekend *sigh*
Then I'll have somewhere fee free offline to store my coins...

Just finished downloading today, took about 48 hours.

Where in the PC is the blockchain stored so I can see how big it is?

I'm on OSX and it's in Library>Application Support>Bitcoin - I'm not sure where you'd find it on Windows, but I assume it would be similar?

Thanks. I've looked around my win 7 installation and found it in AppData -> Roaming -> Bitcoin
The current size of the bitcoin folder is 14.5 GB

According to the Blockchain.info, the size is 12,107 MB right now. But it can take more space in your system.

That's fine, I was just a bit worried it would be like 50GB and I'd hit my data cap.

You should be careful about running a full node on the PC once the blockchain's sync'd. Especially if you have high bandwidth, you'll very quickly run into your limit through sharing blocks and relaying transactions.

Well while I've got a data cap at the moment, I'll be moving to Australia in the next 2-3 months where I'll get an unlimited connection - so it should only be a temporary problem. In the meantime though, is there any way I can stop my full node from operating if it ends up using too much data? I assume closing the wallet client won't do anything...

So, what do we do to avoid running as full node? I'm downloading the bootstrap file separately from source forge, and it's 9.9 gb zipped, should be done by the morning and then there will be some catching up for it to do but at least it will save my hard drive.

PS
Download Link: https://sourceforge.net/projects/bitcoinblockchain/files/29-10-2013/ Download Size: 9GB (Compressed) - 13GB (Decompressed)
Re-directs to the most recent version.

You can even get a torrent for it.

Netlimiter will work well for it. Some other solutions may also work. Once sync'd, QT can still be functional with a limit of ~3kb/s https://bitcointalksearch.org/topic/selfish-node-min-bandwdith-needed-for-bitcoin-core-tons-of-other-data-334778

I have wondered this too and haven't even taken the time to look and see how large it is. Yeah, they have to do something about this at some point. I mean you can't have like 100 gigs required to buy/sell BTC, the hardware will become too onerous if they want to get everyone using it. Why can't they just eliminate some of the "older" transactions? Or, how about making it optional whether to download entire blockchain or only a part of it?

So what solutions are available to not have a massive blockchain on one's pc? Are you stuck with it unless you want to chance a hosted wallet?

If you want to keep your BTC safe, you could do a paper wallet from a hosted environment. But i guess that technically wouldn't be the safest as you do need the internet to generate the paper wallet which has the public/private key available.
