hi , I'm lookin for blk dat for download , do any of you know where I can find them? without install bitcoin core?

See Bitcoin block data (728 GB): inputs, outputs and transactions (https://bitcointalk.org/index.php?topic=5307550.0).

Unless you mean the actual files like blk00005.dat. In that case I'm curious what you want with them.

Not all blk files, but this guy keeps an archive of pruned blockchain of about 2.2GB worth of block data: https://github.com/Blockchains-Download/Bitcoin/releases (https://github.com/Blockchains-Download/Bitcoin/releases)
If you're only looking for some latest blocks, you might find it in one the release. (refer to the date of the release to match your target block)

"Ensure all files are in the same directory. Check the Bitcoin-Blockchain-DATE.exe to ensure it is digitally signed by Rare Ideas, LLC. Run the EXE. For Bitcoin Portable, select to extract the files to your BitcoinPortable\Data\Bitcoin directory."

I'm suppose there is included in exe file , sniffer for privatekeys:) , not to use...!

So every GitHub repository that has ".exe" in it are private key sniffer, huh.

The repository isn't' mine but the exe file is a variation of 7z archive tool to extract the compressed files "Bitcoin-Blockchain-2022-07-10.7z.001~003".
If you already has 7z or similar, you can extract those with it.

I've just given you an option, use it at your own risk.
Use Bitcoin Core for the safe option.

So every GitHub repository that has *exe in it are private key sniffer, huh. -> you should think that there is :)

You cannot unpack and  you can extract those with 7z


I've just given you an option, use it at your own risk. -> as always :)

I get what you mean but it's quite amusing that it's coming from a person who's asking for unverified block files.

How about assumevalid=<latest block hash>?
You can add it in your Bitcoin Core's "bitcoin.conf" file or as command line arg and your IBD will be faster. (after the default assumevalid block)

Answer:) :  I'm ask becouse I would like finish my job, , few hours ago my external hard disc fired , and I lost my database. I ordered new and I'm waiting for deliver.


:)

In that case: you're not using Bitcoin Core to trust others, right? So just install Bitcoin Core on your system, restore a backup of your wallet.dat, and let it sync. If you're low on disk space, let it prune. With a modern system and decent internet it shouldn't even take too long.

I do not understand : I do not believe that exe file is clear without anything inside , in this example I do not to see any reason to make exe file for unpack the files which are not 7z - try download and unpack.


I'm using BTCore , but I had on external disc.:)

It's been a long time since I've seen a compressed file with executable extension for extracting it. I wouldn't use it anywhere else than in a VM I'm going to wipe afterwards. Better safe than sorry.

So just redownload it on a local disk :) No need to risk your funds.

For the record, those files are 7z, the extensions "7z.001", "7z.002" and "7z.003" indicates that it's a 3-part split 7z archive.
Also, anyone can just skip the exe file, any tool that can extract 7z files will do.
