Blockchain Download

[Small]

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.

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..

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?

Blockchain itself is decentralised. BLOCKCHAIN.INFO is a centralised SERVICE. They store encrypted private key on their server and send the encrypted private key to you when you submit a request or submit the correct 2FA. If they were hacked, you could get hacked too, depending on their algorithm. Additionally, they have a lot of vulnerabilities in the past.

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.

This is bullshit. You can sell the blockchain because it is public database and there is no license attached to it. You can also sell most bitcoin wallet software including bitcoin core because they are released under the GPL and the GPL allows you to sell software. That's how redhat became a billion dollar company.

Edit: actually bitcoin core is released under mit license which is even more permissive:

And their API is horrible. It keep causing bugs and issues with services that include it. Blockchain.info is a online centralized and not all that secure service for carrying your Bitcoin and to be honest, it is probably not a good one.

I think you should instead run a good SPV wallet for convenience, that way you have no need to hold the complete blockchain and if you wish to have a online foothold to put your bitcoins in the hand of a third party for a moment, i would recommend Coinbase.

I am actually already using Coinbase and like their service. If you have a large amount of bitcoin then you can place it in their "vault" and either use 2FA with your phone, your other emails, or another person's email. Which would be useful for large businesses as they could have all of the executive leaders confirming the release of money. Coinbase also have a 48 hour cancellation period where the money will not be sent until that periood is up and the transaction is not terminated! If i wanted to create an online bitcoin site then I would have to find a way of recalling the data and manipulating the data to view what transactions have been sent to my account.
