Blockchain Download

[jackg]

Could anyone send me a copy of blockchain or tell me where I may be able to find one. I feel that this may save power from my internet and laptop as verification of blocks can be done offline. I already have online accounts with coinbase but am thinking of getting a bitcoin wallet that is more secure.

blocks verification can't be done offline (cmiiw). I think you may have misunderstood something.

to answer your question. use bitcoin core and let it sync or google bitcoin bootstrap.dat torrent. though I don't know if there's still an up to date version of those.

from the thread: "IMPORTANT NOTE:  As of Bitcoin Core version 0.10.0 or later, this torrent is slower than a direct download using the bitcoin P2P protocol & client.  This torrent is now only maintained for research and development purposes as a secondary option.  Please use Bitcoin Core directly to download the blockchain."

i recommend use a light-wallet which dont sync full blockchain (if you don't need full blockchain). light wallets (electrum & co) still are very secure and NOT CENTRALISED like blockchain.info or coinbase..

You will still be need to be online to download the blockchain. And then be online when you start it for it to go through the validation progress. It shouldn't take much power however, if 100w is a lot of money for you, i don't think crypto will work out for you anyways.

If you're just trying to do some transaction then get back offline, get a SPV wallet. Here;

You can buy them, on USB stick if you want to, a complete blockchain. But I don't know why would you be doing this.

If downloading the blockchain is so troublesome for you and your computer, then maybe you shouldn't be doing it. There are many other lite wallets out there that are working just fine. Just stick with those!

I believe that the block verification can be done offline, it does not need any info from peers to verify the blocks.
Even if someone does send you a USB copy of blockchain, it would be outdated and you should have to synchronize it online again, and you would have to do it everytime you want to send a transaction. AFAIK, the power usage doesn't matter much whether you synchronize online or offline as the client would still have to verify each block individually. SPV are nearly as secure, ignoring the tiny risk of having not verify the entire block.

Valid points have been made. If you still want one you could try to contact, he offered the service at one point: https://bitcointalk.org/index.php?action=profile;u=61202

The power of my laptop is 80W and I don't know about the internet power.

How long will the synchronisation of a 2.6 GHz processor and a 50mbs. Any way of calculating this?

The power should be relatively low, around 10 watts. The speed of the CPU does not depend solely on the clock speed but also on the IPC (Instructions per cycle), giving us your CPU model would help more. Your internet speed is unlikely to be the bottleneck around here, using SSD would speed up the process significantly. In the end, whether you transfer the blockchain from USB or from peers, the time taken would be roughly the same as it takes time to both verify and transfer the files from USB to your computer.

Basically, OP should be doing this on a RasPI and the only reason to do this would probably be running a node or something.

So again, jackq, why are you trying to do all of this. Are you trying to just set up a wallet or you want to run a node? Because it doesn't really sound like you're trying to run a node 24/7, thus getting bitcoin core in your situation is probably not the way to go.

How long would the installation/download take on my raspberry pi b+? And I can leave that connected to the modem without any other aplications running but i  will also need to use my 5tb seagate expansion drive on that? I have already started using that with my windows version but I suppose the blockchain I have already installed will be the same for all operating systems. I should add that I am not willing to overclock as that will damage my CPU and that I have raspbian installed. Why does everyone assume that people have a reaspberry pi? It is a very good and small computer though!.

Depends on your download speed and the processing speed of the Raspi which might be pretty slow. Maybe some user who set up a node on a RasPi could help you, or do some reading on this search;

But you still have not answered; Why do you want to set up Bitcoin Core this way?

I want to install the blockchain before it gets to a point where it will take years to install! I also want to eventually run a website from the Raspberry Pi and sell the copy of the blockchain download. I want to know how the databases are set up in order to do this and will so inspect the format of the data directories and the blockchain locked databases in order to learn more about bitcoin and how i can manipulate parts of it in order to program auto payments from a website.

That sound borderline illegal. It's open source, if you sell it for profit you're breaking the license. Its also available for free, downloadable for free and the bootstrapped downloadable for free, all under the same open source license.

And there's nothing to learn its just a bunch of heavy .blck file that you slap in the AppData roaming folder, then let the wallet sync, which still would take a while.

And you can't manipulate parts of BTC.

I meant that i want to create a piece of code that runs of my website that will send money from my wallet to theother person's waller. I am not trying to find flaws in the bitcoin network to exploit I am just trying to create an auto payout service for a wesite so that is sends payments to users from my bitcoin that I own!

Thats okay, but you said "sell copy of the blockchain download". There's many way to spin this but you'd simply be breaking the license in any case. If you're trying to make a payout system, then sure and running a bitcoincore can work, even though there's better options, but you'll also need cold storage.

Cold Storage? What i cold Storage?

If you mean physical storage I have a spare 4.43TB that could be used for this!

Cold storage mean offline storage. A wallet that has never and never will touch the internet, that way you can say with fair accuracy that it's impossible to steal its privkey. Otherwise you're susceptible to getting hacked. Especially when you're not an expert on internet security.

This explain cold storage for Bitcoins;

I have another hard drive that this could be done with but will keep up stength on both and may even force users to have the information manually confirmed, thus, eleminating the chance of theft by ensuring bitcoin isn't stolen or misused from our cloent's accounts. Will also try to run a python program which will select 1000000 characters that will take up less than 1mb of space which can be stored offline! Thus further eliminating chance of theft.

But although blockchain is centralized, isn't it only unencrypted in your browser, so I'd they were hacked, you wouldn't lose your bitcoin, only if you yourself were hacked?
