Topic: Verifying Bitcoin Core - page 2. (Read 210204 times)

Yes, if you use bitcoin core, then you must download the whole blockchain.

---

If you run Bitcoin Core, it will download over 200 GB of blockchain data.

If that's too much for you, you can use something like Electrum: https://electrum.org/#download and it will hardly download anything at all. There are tradeoffs: Electrum isn't a full node, you're connecting to a random Electrum server (which has indexed the full blockchain so you don't have to), and telling it which addresses you own. So you're giving up some privacy for the sake of convenience. Lots of people do it.

I am confused, I want to download a bitcoin wallet to my windows desktop, it says the bitcoin core is 200+gb in size, does that mean you have to download all that size to use a wallet? is there no other quicker and easier way? Sorry noob here

You must be Change Certification Trust from Wladimir's key to Full Trust or Ultimate Trust,

If you are using Kleopatra (Microsoft Windows):

If you are using GPG Keychain (Mac OS):

Have I correctly verified Core?

I've done this following but am a bit out of my depth:

1. Downloaded and installed Kleopatra (GPG4WIN)
2. Imported Wladimir's ASC from Bitcoincore.org
3. Downloaded bitcoin-0.17.1-win64-setup.exe
4. Downloaded SHA256SUMS.ASC from Bitcoincore.org
5. Verified SHA256SUMS.ASC was created with Wladimir's certificate via Kleopatra (*See below)
6. Obtain SHA256 hash of bitcoin-0.17.1-win64-setup.exe (**see below)
7. Confirm the SHA256 hash matches the SHA256 hash in the SHA256SUMS.ASC file (***see below)

As far as I can tell this is correct, but step 5 has me a bit unsure, mainly due to the following:



I am led to believe that this message is correct, and that 'The data could not be verified' is simply a result of me having not verified Wladimir's key via Kleopatra.

Does all of this look correct?

The thread was last updated in September. You could go here, choose whatever version you want and then download the SHA256SUMS.asc file.

Is the 1.7.0 or 1.7.0.1 signatures available on here?

I downloaded Ver 16.3 as it was "urgent" - I downloaded the block-chain (again) 'cause bootstrap and porting dat files didn't work... Block chain is now downloaded but:

• There's yet another version "urgent" update or risk life and limb.
• All the wallet addresses start with "3" not "1"

Nice one people - WTF!

Just wanted to ask the same question. And what information I must learn as a beginner? From which forum here should I start?

Is it possible to have the 0.17.0 release signatures added?

Bitcoin core am well sure is an implementation of bitcoin which was published by it's great founder satoshi Nakamoto under the name bitcoin which was later renamed bitcoin core,in other ways view company have been regulated for they release of hash,they process it's self has been documented BIP2 and BIP123 which are categoried

Is there room for me to chat privately with a contributor on this platform?

does this update require resyncing the blockchain?

How to know that your license and certificate are not fake?

Be humble respect each other and help people specially for those people who needs help.
thanks for all of things

Use Google.

What about if i have Ubuntu with Bitcoin core in the PPA?  its auto updating it, i dont do anything manually beside clicking on Update  Huh

The downloads for old versions are still found on the website. As long as the user was not on some phishing site, everything is fine. I would still recommend using the latest version given how much better it performs versus the older ones.

Hope you misstyped the version, on bitcoin.org the release downloadable is the 0.15.0.1 not 0.13.0, so i hope you downloaded the last one.

bitcoin core is the first and one of the oldest wallet for bitcoin, is good but you have to keep in mind that it downloads all the chain on your computer so you need a lot of space almost 200Gb.
