Title: Bitcoin Core Wallet & torrent of Bitcoin Core
Post by: Faliro on August 25, 2017, 10:48:04 AM
Hello

I will install a fresh copy of Bitcoin Core Wallet to an old computer and also Armony wallet

My question is:
Because it's an old system and the synchronization with the block chain will take forever,
can I download the torrent of the core and somehow  "install" it to the destination of the wallet so to be synchronized immediately?

Or even better, not using the  Bitcoin Core Wallet have the torrent core directly to Armory Wallet???

Thank you all!

Hi!

The bootstrap torrent file contains a large portion of the blockchain that you can copy into Bitcoin Core's data directory. However it will not be synchronized immediately for 2 reasons:

1) The bootstrap torrent file won't be up-to-date so you will still have to download a significant number of blocks

2) Bitcoin Core / Armory will need to scan the blockchain for relevant transactions (ie. transactions that affect your wallet)


Be careful what you download though, I think there currently is no "official" bootstrap.dat file.


Unless Armory has had a major update lately that I'm not aware of, you'll need Bitcoin Core to run Armory, as Armory relies on Bitcoin Core. If set up correctly, however, Armory should just automatically run Bitcoin Core in the background.

JGarzik here, a previous core dev, made a bootstrap.dat of the block chain. If you have to download it, download it from him - it'll be a bit safer though I'm not sure it's still updated or not.

It depends on how much security are you willing to trade off. It is definitely fine to run the bootstrap.dat for Bitcoin Core to synchronize the client using it. The client will verify each block independently to ensure that it is valid. It will hence, take much more time for it to synchronize, also with it not being synchronized with the latest block.

If you are referring to the whole data directory, you are sacrificing quite some security in this case. For starters, Core doesn't realise that the data directory is from a foreign source and will not verify each block. You are relying on other people to do it for you. Not that is a huge security risk but its still there.
