I want to create a new bootstrap.dat file for a Dogecoin. How do this kind of files are created and how can I create one? What tools should I use? any answers/links/references are appreciated. I have searched here, but I haven't found any satisfying answer. I saw this post: Creating my own bootstrap.dat but there is no method mentioned of putting the block in the bootstrap.dat file. Saw this post too: How do you generate a bootstrap.dat file? but the tools mentioned are for Bitcoin and I'm not sure how to use them.... can anyone create a more explicit, step-by-step tutorial for doing this? something that anyone can understand? thanks in advance!

Since van der Woerdt's answer in first question you link to indicates you can simply concatenate the blk files, you can open a DOS window (if your using windows), then type

CD C:\Users\<my_user>\AppData\Roaming\DogeCoin

(if you're on Win7+)

And then

COPY /b blk0001.dat+blk0002.dat bootstrap.dat

And that would be it!

  • Well I didn't knew exactly what he means by "concatenating", but if it is that easy then it's awesome! thanks a lot, I'll give it a try!

  • Why there aren't downloads available for this? It's a waste of connections syncing over network.

  • @nobody: "To concatenate" means to attach sequentially after one another.

 From Mac

  1. Open terminal

  2. Go to the folder where the blocks are. In this case Bitcoin's folder (it's the same for other bitcoin forks)

    cd "/Library/Application Support/Bitcoin/blocks/"

  3. Run this code that will concatenate all the blk files. In this case there are 4 so you would do:

    cat blk00000.dat blk00001.dat blk00002.dat blk00003.dat blk00004.dat > bootstrap.dat

    You can also use the * wildcard to insert them all onto the bootstrap file, or a determined range delimited by the wildcard. Like:

    cat blk0****.dat > bootstrap.dat

  4. Done.
