Every time I finish installing the Bitcoin wallet client, I have to wait a long time for it to sync the blockchain data. It’s already over 80 GB now, and syncing could take 3 to 5 days. So I backed up the blockchain data to use directly next time, which makes syncing much faster. Today I’ll share how to use ready-made offline data.
First, a word on security. No matter where you download the offline blockchain data, you should run a virus scan to prevent trojan infections, and then check the file contents for any executable programs like .exe or batch commands. If there are any, that’s abnormal — don’t use them. The Bitcoin network validates every transaction, so you don’t need to worry about the authenticity of the blockchain data: if even one block were faked, every subsequent block would change, so the data is safe.
First, download the offline blockchain data to a folder on your local computer.

I upload the blockchain data once in a while; you can pick a day’s data here — the closer to now the better. Click in and you’ll see the blockchain data; you need to download all of it to a folder on your local computer.
After downloading the blockchain data, put your wallet file in there too. If you don’t have one, ignore this step — the Bitcoin wallet will create a new one itself.
Then configure the Bitcoin wallet client to point at the new blockchain data folder, and double-click to launch the Bitcoin wallet client.
Then, because our wallet backup time and the blockchain backup time are out of sync, some transactions regarding your own wallet won’t show up, so we need to have the wallet recompute the blockchain data from start to finish, writing the new transactions into the wallet file — and at the same time this is a check on the blockchain data. I’ve forgotten the command for the moment; I’ll add it here when I remember. You can Google it in the meantime.
