Bitcoin QT blockchain

[monsterx]

Is there any other way to download the QT blockchain instead of waiting approx. 2 weeks while it downloads through the wallet program?

Sorry for dumb question...

find a bootstrap.dat

Most of the waiting time isnt really a bandwidth issue, but is the fact that every block and transaction is scanned to make sure it follows all the rules.

If you have a decent internet connection, you can download it faster. The time left to download isn't time it will take to download. Bitcoin Core 0.10.0 is faster. Try it if you are using older versions.

If you don't have enough storage or connection, you should probably go for SPV clients.

And what should I do with that?

As I've read, starting with 0.10, a bootstrap file is no longer needed, as the blockchain syncs much faster. Just boot up 0.10 and wait for it to sync...

Thanks a lot, I will try that.

Yes, with 0.10.0 using the bootstrap will make the sync slower. Lets assume you can download the bootstrap with full speed as well as download blocks with the full speed your connection provides. The bootstrap.dat will be verified after it is fully downloaded, while the regular sync via 0.10.0 will let your machine verify the blocks while you download them.

@OP if you have problems finding good nodes to use the full potential of your connection, try adding some of these below. You can add them via:

Code:

addnode IP add

where you replace IP by one of the IP-adresses from the list. You have to enter the command in to the console (Help -> Debug Window -> Console)

Code:

I use electrum because of that.

not only synchronising blockchain, I don't have enough space the store the blockchain :/

[Amph]

yeah there is

buy a evo ssd, it will sync the whole blockchain in 1 hour(tried it myself), and it's not expensive at all

For most of us the bottleneck is probably still the internet connection. Even slow mechanical disks can write >30MB/s on average[1], even a 100MBit/s connection will not deliver 30MB per second. In order to to sync within 1 hour you would indeed need a 100MBit/s connection and the disk should not have a big impact, since you would receive data at ~9MB/s, unless you use the disk for something heavy at the same time.

well that's wierd because with my 850 pro i've synched the whole chain in 45 min, and i don't have 100mb, but only 8

Someone here can show me what is "block reward" ? I don't understand that.

When is "block reward" is 25 BTC and when is 50 BTC or 100 BTC,....

thanks !

A block reward is what's distributed to miners when they find a block. The reward is now 25 BTC and doesn't change until the next halving.

There is a bit torrent with the blockchain if I rememeber right.
There is also someone in the market place selling USB drives with the blockchain pre loaded on.
That is a great idea, it is not smart to download all those 30 gigabyte everything you reinstall your computer.
Better to have the chain on a USB stick. Peace.

The torrent is useless now with Core 0.10

And you don't have re-download the blockchain everytime you format your computer. Simply don't delete the blockchain folder... Put it in your storage partition, and just point Bitcoin Core there

Why is that? Is the torrent not compatible?

What part of the Bitcoin-core installation folder to you need to back up when reinstaling?
Is there a part of it that is the block chain, or can you just save it all, and put it back on the drive after you have reinstalled?
Thanks 

[emrebey]

see datadir parameter. you can backup/restore later on. if it's not given, look for the default directory.

Oh, that was very helpful, thank you man
No need to reinstall right now, but I will remember that post,
when the time will come for reinstalling.

The torrent is compatible... But with 0.10 you have no advantage in using it

As for the blockchain, you have the datadir option as replied. The default dir is on %appdata% in Windows and .bitcoin in Linux. I always have it in a separate partition that's never formatted.
